Will dual banana plugs work with spring terminal jacks?
An amp with A and B speaker channels, where A and B can be played simultaneously, like my JVC ax-2. Eg. Connect your highs to the A channel and your lows to the B channel, select A+B. Biwiring with a single channel, or single pair of channels rather, is pointless. Thought that was obvious.
My step dad tried to explain bi-wiring and my thoughts were the same as this video. I have the same polk audio speakers as the video also and never used the bi-wiring feature because it never made sense. How did this feature make it out from the drawing board I’ll never know 😂
Tons of brands have it and since not a single one explains what's *truly* happening I made this video series.
Wouldn’t the “best” be to utilize two amps, one that performs better in the higher frequencies for the top end and an amp that performs better in the lower frequencies? Something like a class A/B with more wattage and bigger power supply to drive the larger mechanical woofers etc maybe even digital. Then maybe a class A or tube for upper end??? And maybe ultimately four mono amps? A very good compromise could be two Parasound JC 5 dual mono block amps…. 🤓🤓
Perhaps you missed it, but this video addresses bi-wiring *only* and not bicycling nor bi-amping. If you don't understand the distinction it is explained at 3:27. Should you wish to discuss other topics such as bicycling and bi-amping you should find other videos to do so. Thanks.
@ no I didn’t miss anything, I was simply striking a conversation out side of the “bi wiring” aspect. Simply hoping to have an intelligent conversation. Sorry if I stepped outside of the rules.
@@titaniummaster1532 Sorry if i overreacted. I apologize. In a nutshell I do not recommend PASSIVE bi-amping which is why intelligent people call it "fool's bi-amping", a term perhaps coined by Chuck Hawks, and like bi-wiring I suspect it was concocted by dealers so they can dupe consumers into buying 2X amplifiers. Can you think of why? Because it has a clear benefit . . . . *to the dealers*: they make BI-profits on each customer that falls for their scam. As for the notion of using an amp that's good in the highs for the tweeter and one that's good in the bass for the woofer, why not save money and buy a single solid state amp that's good in both the highs and the lows, true of around 99% of the ones out there in modern times (contrary to the liars pushing passive bi-amping), assuming you seek high fidelity to the input signal. If on the other hand you wish to color your sound to taste with fixed, non-adjustable aberrations you have no control over (like from a tube amp) nor can defeat with the push of a bypass button, then buying one amp the mangles the sound one way for the tweeter and another that mangles the sound going to the woofer, because you seek to creatively alter the sound (not my bag) that might make sense, but my goal is to faithfully recreate the amp's input at its output. That is, I agree with Quad founder and amp and electrostatic speaker designer Peter Walker, who wrote: " "the perfect amplifier is a straight wire with gain" and also ""An audio power amplifier is required to produce an output signal that differs from the input signal in magnitude only." [So any other difference is inherently a distortion.] If instead of reproducing the entire range of frequencies (both the bass and treble ) accurately you find an amp that instead changes the sound in some manner besides just level, there's name for that: a crappy amplifier. ACTIVE bi-amping, however, is completely legitimate but to execute it properly you need to entirely bypass your speaker's crossover. Simply removing a speaker's jumper straps does not accomplish this (at least for about 99% of them out there) and instead use an external electronic crossover to separate the highs from the lows pre amplification. It's a lot of work for only modest results and I also would never suggest actively bi-amping unless you use measurement gear to get the levels correctly.

Sooo... bi-wire is pointless unless you amp the two separately, correct? I thought this was to whole point of being able to bi-wire.
What speaker (with a double set of input terminals) do you use?

@@opietaylor6507 Page 4 of your owner's manual shows, using nothing but wires, how to bi-wire: www.martinlogan.com/uploads/documents/manuals/Motion_XT_Motion_Series_Owners_Manual_REV1.pdf Yes, to answer your original post's question: it is pointless to bi-wire assuming an adequate single wire is already in place, but nearly all companies, including yours (I was a ML dealer, by the way) describe how to bi-wire because the dealers like it when their clients BUY wire, especially when its twice as much wire as they actually need.
Bullshit.
What a compelling, evidence-based argument you make.
@@m.zillch3841 thank you
If there is not a crossover/band pass filter on the high frequency posts, you're going to blow the tweeters, if you send it a full range signal.
There is no bi-wireable speaker on the market that does not protect the tweeter from the bass frequencies. Although some consumers mistakenly think they are bypassing their speaker's crossover, they aren't.
@@m.zillch3841 his diagram sure doesn't show that.
Some high end esotheric gurus will disagree, but this is the real thing. Thank you for speaking out the plain truth.
Thanks! Spread the word by linking back to my vid.
This is such s waste of time and money. Just use the proper wire gauge.
I'm glad you agree with the video.
The fact is there is no sound difference to the human ear. Save your money & time for better upgrades !
Well ,,, is bi wiring terminals not made for bi amping ? Thats the only way you can bennefit for bi wiring ?
Well .is
I realized this years ago when this nonsense got started. Seperate terminals for bi-amping make since though. Therefore, supplying speakers with seperate terminals makes sense in case one wants to bi-amp.
so "bi-wiring"actually means "buy-wiring" . That is neat.Thanks for the great video.
Yes, it means "(needlessly) buy 2X wiring"
Bi wiring is so you can use separate ISOLATED amplifiers. One amplifier for the highs, and one amplifier for the lows. (OR LOW MID HIGH IN A 3 way set up but I digress) So you could use a low wattage Tube amp or Class A amplifier for the tweeters/mids and a Hybrid amp, class AB or D amplifier for the Subwoofers. PASSIVE Crossovers could be used before the amplifiers or ACTIVE Crossovers and or even a graphic EQ's or before each amplifier to limit what the amp is SEEING to amplify either full rage vs HIGHS, MIDS, and LOWS... this conserves power and lowers amplifier distortion, as low frequencies require more watts and current. where as the mids and tweets can get a CLEANER less THD (Total harmonic distortion) and a lower noise floor. - Just my opinion - Thought I would share a different point of view.
This video is about bi-wiring, not bicycling nor bi-amping. They are three different things.

Dual post 2 way bi-wire (08:13) makes zero difference. Utter nonsense...
I'm glad you agree with the video, rather than the Polk owner's manual (and others) I quote at that timestamp.
Buy wiring, try wiring. Whatever sounds good to you is all that matters.
For people who don't care if they are being duped by marketers, yes.
Just last week only ,here in India ,one seller was selling a refurbished amp and used this term of bi wiring,which I had never heard before ,I am now 65 years of age.I was wondering as to what is this new evolved technology .You really cleared my doubts.I think we must use thick speaker wires between Amplifier and the driver and let that wire do the rest of the distribution etc .between woofer and tweeter which hitherto is still happening.Thanks again for busting this myth of biwiring.
Bi-wire speakers force a jumper if you don’t bi-wire. That’s got to hurt the sound.
Pretty much all 2-way speakers have this Y-split in their overall circuit, either inside the cabinet (hence invisible to the owner) or externally (i.e., bi-wiring posts) so the single amplifier can feed both the tweeter and woofer sections and the most reliable way to do it is with wires properly soldered in place INSIDE the speaker cabinet. Instead adding extra binding posts externally, connections, jumpers, extra wires, extra terminations at their tips, etc. is simply increasing the points of potential failure, oxidation, poor conductivity due to human finger print oil, and botched polarity (the consumer errantly mis-wires the + and the - or the sleepy factory worker making the speaker does).
There is a wave that, having nowhere to go, goes backward. That over a long stretch vs short stretch could matter.
That's like saying "handheld flashlights with long bodies don't work as well and are dimmer because the electricity powering the bulb/LED has to travel farther." . . . I explain the marketers' common lie regarding back-EMF here: 11:46
What about voltage drop? Two loads on a single wire will cause more voltage drop. The tweeter (being the lower powered load) will therefore get less voltage than the woofer. How much less will be proportional to the current flowing AND the length of the wire (and the cross section of the wire). Of course with sufficiently thick wire the effect will be negligible, but is the threshold low enough that this is a concern?
The block diagrams are the same so the circuits are the same. Assuming adequate wiring is used there will be no audible difference.
@ the circuit diagrams are the same but that doesn’t mean there isn’t a difference. Voltage drop will be present. It’s only a question of whether it’s a significant value to affect things. Saying “assuming adequate wiring is used” is a lame response, without defining what’s adequate.
@@frodev728 Regarding conventional single wire connections, since a user-prepared 5.00 meter speaker cable and another that when precisely measured is actually a 5.01 meter length have a slightly different resistance, I guess there must be a "difference" in the load the amp sees between the two, right? That's essentially the same sort of scam the bi-wire marketers use: rather than doing what's rational, i.e., doing a comparison of bi-wiring against a single wire by ear (under *BLIND* test conditions to preclude the possible influence of expectation bias-which they clearly avoid because they would fail such a test), they instead demonstrate that if you have a highly sensitive multi-meter you can measure small differences such as either the change in resistance between a 5.00 m. and 5.01 m. wire, or, if you prefer, conventional single wiring vs. bi-wiring, and then they proclaim, "See! Measurements don't lie. This proves it. There IS a difference!" Also, I defined what I meant by "adequate wire" by providing a link to McIntosh engineer Roger Russell's site both in the video itself at 25:15 plus also in the video's notes with a direct hyperlink. [edit: provided timestamp in video now corrected.]
@ thanks for the extra detail. I was somewhat multitasking whenI watched this video so I missed some of that detail, apologies. I’m not trying to be contrary at all, I’m just relating this to things I do understand (from my work as a leisure/auto electrics installer) where voltage drop is a very real issue that needs consideration. As I’m not familiar with the voltages and currents involved in driving a speaker (although I assume they are very small compared to what I’m used to working with) I wasn’t sure if the voltage drop would be significant enough to be an issue. If it didn’t come across in my previous comments, I found this video really interesting and wasn’t intending to refute it. thanks for your considered response.
@@frodev728 Fair enough
Well we make the Artillery folks work outs, lol! Actually no, this is outdoors, at the Boston Massachusetts Hatch Shell, next to the Charles River. Tho folks in apartments across the street get a l smoke 🤣😁! Hello from (almost Boston, l) Salem Massachusetts, US!
Hello Salem!
my right speaker is broken
Distorted or totally dead?
Unless the amplifier can split the low and high freq. directly before it can hit the output jack, then it could. But it would have to be setup to do that, either buy aCPU or some other means of separation. I knew I was right about this crap all along. Signal is just signal, positive and negative on the terminals. No extra filler or frills. Still it amazing to me how music come from an amplifier to a speaker to begin with.
11:03. I do not think that was a fair test to try and give people. No one is going to be able to know exactly where the speaker box is going to end. That is something that is only known by the creator and no one could not answer that would out it being just a complete guess and or reading your mind somehow. To test to see if someone was able to learn from the content that was posted you should ask a question in witch the answer for the question was previously taught.
The point is the location of the box is immaterial to the electrical circuit however the cabinet location *tricks* people into thinking bi-wiring is "electrically different" where in truth it isn't. Assuming adequate wiring is used there's no difference.
For a minute there, I thought you swapped the Polk Speakers for one made by Bose. 🇺🇸🧙🏽♂️
There IS a difference when you have to use a longer speaker cable like 5 meters. Than biwirengcane bring a difference in sound, because the loss for the tweeter is lower, especially when you use a thinner cable for the tweeter. Call me grazzy but it sounds plausible.
If you use an *adequate* wire in the first place there is no difference.
@m.zillch3841 So you say...
Hello. Bi wiring is doing nothing except skipping the crossover and supplying the individual speakers too much bandwidth abd the wrong impedance. If the wires are coming from 1 set of power outs there is absolutely no advantage to this. Crossovers are used for a reason. They protect the speakers from frequencies they cannot or do not need to reproduce. Bot to mention the fuse in case of overload. If you want better more precise sounds bi amping is what you want. An active crossover is used and then the signal goes to separate power amplifiers that are matched for the speaker. ¹
"Bi wiring is doing nothing except skipping the crossover" Huh? Since bi-wiring in truth does not bypass the crossover I suspect you must have missed this part: 7:25
Thank you..part 1 & 2 answer my concern for a passive subwoofer & stereo speaker combined on left & right channel of an amplifier. Passive subwoofer needs only the crossover & not a separate amplifier should the wattage is good enough. Right?
Passive subwoofers can work but if they run on the same amp channel as the main speaker they put more strain on it so you limit the amp's output before the onset of clipping (distorting). There are several advantages to instead use a *separate* amp for the sub running just the low frequencies via an outboard, active (electronic) crossover (or a "sub out" found on may receivers), usually using a crossover frequency of 80Hz, such as when you use a "powered sub", and then sending only the high frequencies above 80Hz to the amp running just the main speakers. This division of labor principle is called "bass management".
This is so wild how perfectly it alligns with my own setup, coinciding with what it's being shown on the video as an example. I still can't fathom how this is able to being done with just 1 pair of speakers. I use it to mostly check youtube videos audios that seem to prefer to heavily come out of just one of the speakers. Making me feel there's something wrong with the other one. But then with a quick check like this, makes me realize there's some sort of compression, editing, or something on that video's end, and that my setup is just perfectly ok.
TY
You're welcome.
this way you get to buy extra wire.....
That's why it's called "buy-wire". ;)
Why not strip enough of the wire to put it through both positives and both negatives? It then eliminates the cheap interconnects and uses the same wire running from the amp?
That works great! . . . but many designs of wire strippers aren't friendly to stripping that LONG amount of insulation off all at once.
Agree and I find it works great as long as you have decent cables and strippers!
I speak as a novice here, just asking a question. I read an article stating that bit worked - not because "the same signal is sent to both high and low", but because the woofers, tweeters wec...draw their respective current from the amp. It's not the amp pushing current, its the tweeters and woofers pulling their respective current, and when they do this they behave differently. Ie, a tweeter and woofers have different power needs, and they draw as needed. Theyvare not "pulling" full spectrum.ure how the crossover factors into that theory, but it seemed to makes some sense. Again though, learning. I will say, I originally started bi wiring because I had some silver speaker wire. I used it for the highs. You will probably say it's impossible, but you will never convince me that the addition of the silver dramatically brightened the sound..When I sold the silver cable, I added a second set of the cables I already had in there. They difference was really dramatic again I know I am conflating two things, but biwiring this way definitely made a difference. When I added the second pair that sound was gone, and there is nothing jumping out at me that shows that 2 pairs of the same wire are different than one. But when the silver was in there it was undeniable So make of that what you will.
If you watch the complete video you'll discover that when diagrammed the two wiring scenarios aren't just similar, they are EXACTLY THE SAME BLOCK DIAGRAM. This proves the electrical circuits are the same and therefore behave the same. The only distinction is the length of the wires and that the Y-split, WHICH EXISTS IN BOTH, occurs inside a wooden box in one scenario but not inside of it in the other. Electricity does not care if its wire is inside vs. outside of a wooden box so it does not behave differently, assuming one always uses an adequate gauge for the task at hand. Still having trouble seeing they are exactly the same circuit? Then watch part two (which only has narration for short segments and is mostly just diagrams with my homemade sound effects): ruclips.net/video/NJhFxuymlCI/видео.html Another trick to make bi-wiring "sound different" is to use a compromised wire that FAILS to conduct all frequencies properly instead of easy-to-find and extremely inexpensive wires, of an adequate gauge, that DO successfully conduct all frequencies accurately with ease. If you purposefully (or errantly) use a junky wire that, for example, suppresses high frequencies on the run to the tweeter but don't use this same wire for the single wired speaker, the two wiring scenarios will obviously sound "different" but this doesn't prove "bi-wiring works"; it proves you foolishly used inadequate wiring.
@m.zillch3841 I watched it all. I'll watch Part two. It's funny the silver cables were like 8 grand retail. Big, prodigious affairs. I didn't pay that, for the record.. I realize that doesn't mean anything in terms of design. But I have experimented with quite a bit of silver and it definitely sounds different to me it's brighter, and harsher overall. Copper is darker. I had an all silver rig, from tonearm wire, to rca, to speaker cable (notwithstanding whatever copper was in the speakers etc...). The highs predominate and they lack an overall sense of something, for sure. . It didn't sound like there was low end frequency info missing, although perhaps that was the case. Dunno. It could be bad design, But that's not supposed to be the case is it? Is silver not generally considered a better conductor than copper, all else equal? I'm not arguing with you, your explanation makes sense. I was justcsaying thatcwas something i read i found interesting. I'm also not a Cable evangelist. I use Blue Jeans. Nothing special. I think part of the shear difference I experienced with Bi wiring initially may (?)have been due to removing the jumpers that came with the speakers. You likely don't believe that makes a difference either, lol. Fair enough. Like I said. I'm a novice, just fartng around. I love plenty of things some engineer reductionist doesn't believe in, so I like trying things for myself. The world is signal plus noise, after all ;) To be honest, I think i will ditch the bi-wiring and get a decent pair of jumpers because of your video, if it's likely to be doing more harm than good. Otherwise I've been content to leave it as is.
@@jasong6702 In audio people, including myself, often hear things that are just in their imagination due to "expectation bias" aka "the placebo effect". We (and professional audio scientists) work around this by conducting blind tests but that usually requires an assistant and takes time, but it's the only way to be sure one isn't imagining things . . . which happens all the time and the people who claim they are immune to it are simply wrong.
This make me realize that I put my iems in the wrong positions
I had a broken barely working cassette deck that had really much flutter, not wow tho
FALSE: CENTER is a little more at the right. i tested in my studio here. i saw it in my stereo view meter.
Unlike most content we are exposed to, where a single MONO mic is casually aimed at the general direction of a sound source (such as narrator reading text) and then the signal is *electrically* steered into various positions across the sound stage using precision pan pots, this is a fully acoustic event recorded with a guy walking around either a stereophonic mic or set of mics in a particular array. Vagaries such as the exact direction the narrator speaks, a performer's slight swaying left to right or putting their weight on one foot or the other as they talk, the mics' exact positioning/aiming/placement, differing sensitivities between mic capsules, their mic pickup pattern in a polar plot measured either as a raw value ignoring frequency from the far field or weighted to take into account their non-flat frequency response due to things like the proximity effect, frequency dependent cross-correlation values, and room acoustics in a possibly asymmetrical recording venue can all cause the image location to swing one way or the other in a fully ACOUSTIC recording. P.S. This also might be of interest, from the same guy (Chesky) demonstrating how differing mic arrays can alter the sound recording imaging: ruclips.net/video/0P-AoenC5Rk/видео.html
@@m.zillch3841 i understand but in recording studio, center, precisely (EXACT center) need to be exact. people think it's a center reference, it will scrap their mixing with long work, it's really piss off and waste our precious time. it took me 1 year to notice my center reference wasnt in the exact center. i messed my mix. and i come here to have an exact center reference, and its again not centered. the audio of this track should me fixed. or it should explain people this is not exact center at least. sorry and thanks.
I didn't make these tracks, I merely condensed them down to the bare essential parts (in my DAW) to a more useful, short, concise sequence making it easy to place/aim/align HOME audio speakers. The original version (I got from the Chesky Jazz Sampler CD JD37) was well over a minute long with large, silent gaps between the segments whereas my condensed version jumps quickly between the 7 key locations in a matter of seconds to quickly assess a stereo speaker setup. You mentioned you had a situation where your center balance was off but "it took me a year to notice". I guess that means it was extremely subtle? For precise center alignment I would suggest you not use this test and instead should use mono sources, not stereo ones made acoustically with stereo mics in some unknown venue. I have now added this disclaimer to the notes below the video: NOTE: THIS TEST I HAVE CONDENSED DOWN WAS RECORDED ACOUSTICALLY, USING EITHER A STEREO MIC OR A SET OF MICS, so due to the vagaries of room acoustics, UN-calibrated mics with varying capsule sensitivities, their imprecise placement/aiming, a wandering/moving sound source (the narrator walking around the room, probably WITHOUT the benefit of a tape measure and protractor to ensure the exact same distance and stated angle at all times), and a human's tendency to modulate their speaking voice level rather than being fixed in level, etc., the precision of the image locations won't be as exact as if the placement had been determined ELECTRICALLY by pan pot from a repeating, fixed level, MONO track, rather than from this level-varying, stereo-mic'd, live source, human-walking-around-a-room signal generator. This may make this test unsuitable for some users needing greater precision. For precise adjustments a MONO source signal ELECTRICALLY/DIGITALLY manipulated to each exact imaging position from a calibrated, NON-human source would be more ideal than some guy running around a room!
@@m.zillch3841 big thanks
omg i knew the center is a little more righttt i thought its my hearing
Dude all these people that push this bi wire ideology is for fools. I can't believe they honestly think there's a difference. Electricity travels to fast in that short of a distance to make any difference. . There's no difference in normal 2 way speaker wiring with one wire that splits inside the box or your biwiring speaker that has 2 wires run to it if those two wires are paralleled at the amp. If the output of the amp only starts with one pair of wires then the bi wires or single wires eventually end up paralleled.
When the Jumpers are good you don't need biwiring Cables. But biAmping can realy improve the sound when you have two Amplifiers.
Do you mean passive bi-amping or active bi-amping?
@m.zillch3841 I mean one Preamlifier with two Amplifier.
I know nobody asked.. I've bi amped my towers w a multi channel amp. Active through a minidsp2x4HD. "corrected" crossovers to LR4 and "corrected" inverted low end for phase sum. Full Eq of course. Id put it up against any towers costing 10x !
Both bi-cycles and bi-amping are not the topic of this video.
@@m.zillch3841 Correct. I guess I am just supporting those that point out bi amping is a viable option. vs bi wiring. I mention nobody asked because I am somewhat aware I am off topic.
@@kewlbug Fair enough. There are several varieties of biamping and the most common way most people do it, through a multichannel AVR in "passive" bi-amp configuration, is interestingly actually inferior to using a single amp channel of the AVR to drive the full speaker. It would take several paragraphs of text to explain why but once I figure out a way to convey it quickly and easily I'll make a video on it.ACTIVE bi-amping, what I suspect you are doing, is the real deal but the benefits are rather modest; the main reason to do it is more that you increase user control.
@@m.zillch3841 Yes, I prefer full control. Active using all 4 ch on the miniDSP for the towers. amp is a giant 12ch (bridgable to 6). I mostly do car audio sound quality competition stuff. Where every driver is fully active.
Bi-wire = Bull-$hit
Jumpers can present problems. You may find biwiring is more revealing, even if you're not spending a ton on the wire itself.
Bi-wiring in general can present problems because the design inherently has double the number of potential failure points: Double the number of possible loose connections. Double the number of poor contacts. Double the number of bad solder points inside. Double the number of points which may oxidize over the years. Double the number of points to potentially botch polarity by accidentally reversing your black (-) and red (+) attached wires.
Great video!
