Wow. These are unreal!! And no measurements when designing? That “waveguide/baffle” thing is hilarious!!! I’m still a novice but just looking at the wooden Vader grill is a joke! Lol Nice job fixing these! 🎉
Brian Cheney of VMPS worked on a design with someone named Mike Danis. To say that Mike Danis had a very good pair of ears would be an understatement. He saw some potential in a VMPS design and they created something special. It was going to be a new VMPS speaker model. Alas, Cheney passed away and then, so did Mike Danis. There might just be one pair in existence. I've heard it, and it's better than GR Research's big speakers (I've owned a pair, loved them, they were great for what they did), better than Alcyvox (which go for $200K), Wilson Audio AlexX speakers. The world was so close.... Danny, if you're in the area, you're welcome to come listen. RIP Brian Cheney. RIP Mike Danis.
If they designed something that sounded good, it would be the first time. Feel free to send me over some pictures and information on it. I'd be glad to see what they came up with.
Sounds like there are many VMPS owners who could benefit from and open field, a gallon of gasoline, and a reliable lighter. If it weren't for Danny these speakers wouldn't be worth their weight in firewood.
Well the story goes, VMPS was located in northern California out of a guy's home. He had a couple of guy's working in his garage to build his speakers, so there was no factory, I lived down the street from VMPS. He used to advertise in the back of stereo review in the 80's , he built his speakers by ear and sometimes he would put plumbers dum dum around the dust cap and it would end up on the grill, his drivers was purchased as he was able to find a supplier, he was a one man manufacturer, in his home he did not have a lab to do R&D. A friend of mine purchased a pair from a tag sale a we opened it up and he had built the speakers with 22 gauge wire. So the VMPS died when the builder/ owner passed away all of his inventory was left with his wife, she had no audio knowledge, his inventory was spread all around town like flea markets, then I was driving in the same town and someone had left all his cabinets on a pallet in the rain with a sign that read free. I heard he was a great guy. But his company was no JBL .
I remember these speakers from around 2005. I think a guy made them out of his garage somewhere in Northern California? They had a good reputation at the time.
I think the VMPS guy's name was Brian. I heard nice things about him and his speakers. The story I heard goes that he would sell a $20k+ speaker set and then when the customer didn't like them he would then fly out (at his own expense... ) and then set them up properly. This review of his less expensive speakers have changed the way I interpret that story. I have a set VMPS subwoofers (probably just a JBL kit), they sound fine due to the large cabinets but after this review I will look at the VMPS emblems differently.
Brilliant video Danny. I would love you to tackle some of the old Electrovoice Interface range like the C or D or even the Sentry. These are phenomenal vintage EV HiFi speakers but I'm sure your work would make them world beaters.
Inspired by this a year watching this series, I have started fiddling in Vituix. I am working on a two-way design. I applied as much of your philosophy as I could, Danny. I found a tweeter with a low Fs, used a paper woofer, crossed them at 1500hz. I used a 3rd order Butterworth, kept it to 7 parts. I am only modeling, not measuring real world results. But using the same 1/3 octive smoothing, I managed an 89.8 dB sensitivity +/- 0.7 dB. With no smoothing, +/- 1.8 dB. I feel ready for a lesson in testing and creating a test bed. Then it will be time forcabinets including: Baffle Design - Beyond Rounding and Flush-Mounting.
I had a pair of 1990 VMPS super tower II , they were pretty good in spacial ques and sibilance and they rocked and thumped , mine had traditional drivers no ribbon ect drivers
VMPS has been a favorite punching bag of Danny since Brian Cheney was still alive, and occasionally they would spar on web forums. VMPS speakers have taken cues from Infinity in their use of planar and ribbon transducers together with dynamic woofers, but their crossovers have also always been minimalist.
That is not true. I have no favorite punching bags. I treat all speaker upgrades the same and just do what our customers ask. Brian did use to go a bit overboard on the forums and his posts made it quite apparent that he was no loudspeaker designer. He actually got furious with me when I designed an upgrade for the 626R the first go around. He threatened to sue me, sent harassing emails, etc. In the end is didn't amount to anything, and at this point, not even worth talking about.
@@dannyrichie9743 True. But he got furious with you because of the way you presented your upgrade. You used words that just trashed his rep when he was alive. Not cool.
@@davidcrandon2329 I was just as honest about his speakers as I am with every other speaker we work on. Sadly, there was just no getting around the fact that he really had no idea what he was doing.
@@dannyrichie9743 exactly my point. You have no couth.

Don't say all the reviews were bought, or biased, or whatever...
@@davidcrandon2329 I have no couth? Ha, ha, ha..... Brian stuck around for so long because he operated out of his garage, had no real overhead, and nothing better to do.

I made my own sound coat using a mixture of white glue and drywall mud about 1/4" + thick. 12 years later, still in place, cabinets are dead quiet and heavy.
I’ve got a pair of VMPS Super tower R’s. They’re the size of refrigerators with down firing drivers and up firing tweeters. It’s a weird design, but some people loved em. I’d love to get rid of them.I assume the company was bought, because the original owner unfortunately passed away. Or, was that speaker made before? Thanks Danny.
My DIY speakers are similar but I use tri amp configuration with MiniDSP DRC88BM handling the crossovers ..... after tuning with Dirac Live its sounds really really good
This was interesting Danny. I use the same tweeter in my own Quintetta loudspeakers that I designed back in 2004. Are you using any additional circuitry other than the 3rd order network on the tweeter in this upgrade? Great response after your upgrade, I was really impressed with your work on that particular speaker.👍
What was the msrp of these speakers? The build quality is on par with "white van" speakers and the dry wall slurry enhancement really got me! Its amazing how much crap was and is out there on the market.
It's understandable that the virtical off axis would be bad. Those panel drivers probably have even intensity all over, making the time alignment a challenge. But not only for the med and treble drivers, but with the med driver itself! Whereas cone med drivers have center weighted higher notes, and less differences in time alignment.
I guess the guy who designed these really made them to play well in the room they were in with the amplification he had. Any other room or amp, they fall apart.
I had vmps tower ii s in 1990 , they rocked and rolled and with a minor tweak in crossover parts by a friend and it open them up , btw Can you see about the more traditional driver speakers from vmps such as my old pair tower iis
@@dannyrichie9743 Don't be an ass. You are a good speaker designer, but you still have a stick up your ass regarding the arguments you had with him 20yrs ago.
It makes me think of the reviews this and the other loudspeakers you mention received. How could they write well about them, recommending them? Bad faith, no doubt.
Well with this speaker having pots on the tweeter and mid, you could make it sound like almost anything you wanted (in theory) but considering how it arrived to us, I don't think Even Klipsch lovers would appreciate such an "exciting" speaker. ;P
Amazing how little attention was paid to in integrating drivers in these older designs. Sadly, many yesteryear brands were the same, price didn't seem to improve things much either.
Great job again !! Amazing to think how much time and effort they put into product development - without benefite of a measuring mic and system. I don't know the age of these things, but nowadays, there's no excuse. REW and a UMIK-1 for starters at a minimum
have you heard barefoot speakers, and if you have what are your toughts.? ithink they used on old model a bryson amp inside. now they have shiftet to the digital amps hyper night something.
@@dannyrichie9743ok thanks because I bought a 10" Dayton designer and I was going to try to wrap the frame with zip tape , which is used on roofs to stop it from ringing, Then I remembered that the brute was stamped. I also have the designer 6.5 that I used for a midwoofer maybe I should wrap them because I crossed those at 1800 . Thanks
At what distance have the smooth new response been meaured? Drivers measured individually and integrated in software or measured all at the same time with the same sweeps?
We can see how complex the crossover can be. Factor in box volume, design, resonance control. Then factor drivers, behavior, control, reactance, capacitance, inductance. Then factor your upstream components, cabling, amp, preamp, source, each with their own universe and influences. Then factor your room acoustics, control of which remains an amorphous science and expensive. Then factor your own ear with its unique sensitivities. And your musical tastes lastly. Complexities should convert any atheist.
I have a pair of Radiotehnika S-90B speakers made in Latvia in the soviet times. They have their own problems but i don't think they are as bad as the VMPS. I have upgraded the midrange case to a woodcase and it has approx 1 inch of sound damping material inside all around. The old was made of plastic and resonated the vocals. Then i have upgraded the crossover cables from 19 gauge to 16 gauge full copper cable. That made a noticeable difference in the sound details. The crossover has level adjustment potentiometers to adjust the midrange and tweeter level and i have balanced them as good as i can. The crossover has air core inductors out of somewhat thick copper and the capacitors are soviet military MBGO-2 Paper in oil (PIO) capacitors.
I am a noob to crossovers but not to the channel .My speakers sound ok until I increase the volume and then one gets distortion ( not cracking or popping like a blown speaker just odd sounding distortion ) . Is that a sign of a damaged crossover ? cheers
This looks like a speaker designed by someone who wanted their own speaker line but had no idea what they were doing. How on earth did those things sell?
to bad the 4 driver screw holes are out of wack, really wonder how they just trew in the woofer and drilled it in place :) no inserts... while it would not costed any effort since this side had machining on it already. besides the front was made for a different woofer to begin with... looks to be an amazon special ? (Chinese) lure some people in with the planars and ribbon, screw the rest of the design. 2018 model they though slot loading the planar is better... haha
I'm buying a Pair of Bowers & Wilkins DM-220 Stand Mount Speakers with original Stands tomorrow in mint Condition.. They will be connected to my NAD C 3050 Integrated Amp. GR Research or anybody, are these 2 Items any good??? The B&W Speakers are the Black, Silver and Blue version.
Question. Why does your Bully-speaker cost almost 3x as much as your Brute speaker ?. I've been looking for a new pair of speakers for a very long time but everywhere i go, it's always a cheap poorly made crossover and the cabinett rings like a churchbell on sundays. And since you're well known for building really good stuff, i'm having my eye on the brute. And with all the BS going around in the speaker industry now with cheap crossovers = speakers don't perform as they could.. it's almost impossible to find a speaker which doesn't cost an arm and a leg, and is good quality all through.
so what i get some all this, is a company they make planner model speaker, to go niched and then rip ppl of with everything cause they shop there just for the planners hype/. parts express speaker made to milk a niched market sloppy or am i missing something?
the problem with these is they have 2 nice drivers !!! and then they manage to screw it up since they are not competent. they had drivers that many wanted to use., except for the woofer :) they wasted good materials and money from the customer
I get the impression that all loudspeakers ever made are badly designed and this guy is going to fix them all. He must have been sent to the planet Earth from an advanced civilization.
He praises some brands/models from time to time, but most speakers we typically get sent aren't well designed or have issues that need to be addressed. (which is why they get sent to us)
@@hoth2112 I always believe that hifi equipment sound is subjective. What sounds bad for some is honey to others and has nothing to do with brand names. The sound engineers design the sound of their products to please a broad range of people. So saying that some brand names sound bad is not a good idea.
He had a beef with Brian Cheney and they had several rows throughout the years. Interesting now that Brian is dead 12 yrs, he still calls his speakers disasters. I'm not sure why they were critically acclaimed at CES then.

Please be careful. This is a incurable disease. You also really start learning when you get a good measuring system.
Your crossover won't turn out like you think. You have to measure your drivers in the box that you will use them in to model the crossover correctly.

Going where no VMPS have gone before! Stereo Trek
This is a proper speaker review (and fix).
So bored of armchair audio ‘reviewers’ claiming everything is great.
So, the moral of the story is that sometimes you CAN make a silk purse out of a sow’s ear.
It's understandable that the virtical off axis would be bad. Those panel drivers probably have even intensity all over, making the time alignment a challenge. But not only for the med and treble drivers, but with the med driver itself! Whereas cone med drivers have center weighted higher notes, and less differences in time alignment.

GR Research or anybody, are these 2 Items any good??? The B&W Speakers are the Black, Silver and Blue version.
Question. Why does your Bully-speaker cost almost 3x as much as your Brute speaker ?. I've been looking for a new pair of speakers for a very long time but everywhere i go, it's always a cheap poorly made crossover and the cabinett rings like a churchbell on sundays.
And since you're well known for building really good stuff, i'm having my eye on the brute.
And with all the BS going around in the speaker industry now with cheap crossovers = speakers don't perform as they could.. it's almost impossible to find a speaker which doesn't cost an arm and a leg, and is good quality all through.
The Bully adds another mid-bass driver. It steps up the lower end to our servo controlled woofer that also requires the servo amplifier.
Everyone runs off to see if they can't poach some for a steal to upgrade and wind up with a great speaker
80db eff. Wow, would need some real power to get these going.
reminds me: You car was unpimpable! :))))
How much would the upbrade cost? Jusf curious. 😅

so what i get some all this, is a company they make planner model speaker, to go niched and then rip ppl of with everything cause they shop there just for the planners hype/. parts express speaker made to milk a niched market sloppy or am i missing something?
But you didn't tell the viewers how much the ungraded parts kit was ?

Where's the guy who says speakers are to be enjoyed as designed? 😂
Brian cheney didn't believe in measuring or measurement in general.
Years ago I heard one of the big speakers they made, wtf they were awful. Now I know why. The pots, x-over points, 80 db woofer. So many bad ideas.😮
That looks like something I designed! Lol's
Great vidi. I've learned a ton from ya.
That speaker looks like it was built by nasa using ISS technology
I think they might have been designed and built by flat earthers. ;-)
@@dannyrichie9743 If you put in the research you'll find that ALL speakers (and upgrade kits) are built by planar realmers, especially Maggies 🤜🏻 😲
Greatvideo a lot of junk out there
"It would be best to..."
...get a burning permit.
Whoever made those speakers are lucky they didn't get sued for fraud or something.
what a joke. How much are those speakers!? Also interesting about not blowing on ribbon, didn't know that (never owned ribbon) $1600 .
Ohh yah I had that happen, because a door next to the speakers got closed created a pressure wave destroying the ribbon of my magneoan MgIIIa
the problem with these is they have 2 nice drivers !!! and then they manage to screw it up since they are not competent. they had drivers that many wanted to use., except for the woofer :) they wasted good materials and money from the customer
Love u Danny
Where's the other videos of VMPS
This is the only one he's done so far, which is why he talked about the 3 other VMPS 626R he worked on in the past in this video.
I get the impression that all loudspeakers ever made are badly designed and this guy is going to fix them all. He must have been sent to the planet Earth from an advanced civilization.
He praises some brands/models from time to time, but most speakers we typically get sent aren't well designed or have issues that need to be addressed. (which is why they get sent to us)
@@hoth2112 I always believe that hifi equipment sound is subjective. What sounds bad for some is honey to others and has nothing to do with brand names. The sound engineers design the sound of their products to please a broad range of people. So saying that some brand names sound bad is not a good idea.
He had a beef with Brian Cheney and they had several rows throughout the years. Interesting now that Brian is dead 12 yrs, he still calls his speakers disasters. I'm not sure why they were critically acclaimed at CES then.
@@davidcrandon2329 Why doesn't he make his own instead of heaping crap on other people's creations? I'm not buying this BS.
