- I compare the Sundown Audio Xv3 and Uv2. I also discuss when you would want to use one vs. the other. This is part one, the second part is coming soon. Thanks for watching! Part 2 can now be found here: • Sundown Audio U Series...
Авто/Мото
Both have a 30 mm Xmax at 70% bl which is insane as it is. Both get just as loud and both get extremely low as well. The xv3 will play lower or windier. The uv2 is more tight and musical. What set me to buy the uv2 was the efficiency at 92 db and the xv3 at 84. Both can take almost double rms but the x can take even more. I feel the u is underrated especially for the price point. Don’t let the “spl” turn you away they still get super low. Hopefully this helps someone
Great feedback, thanks!
yes me too Id rather take an Sa classic than an X series for music daily that im not trying to just play Decaf all day . My next big purchase from sundown will probably be the new Version 2 U series 18s .
The u has a high fs well the 12 inch does its like 41hz. Is that going to drop to mid 30s after break in or no?
@@akuma4u The fs will drop some, but I wouldn't worry about needing a low fs with the U series, the motor force more than makes up for it.
4.5³ per sub and 70" of port area per tuned to 35hz per 18" sub. Ran the X v.3 18s in the same enclosure. Did awesome on burps but was highly suffering on music. U series enclosures are much smaller than X v.3 enclosures. Just a tip from trying both.
just found your channel im subbed!👍🏽
Awesome thank you!
Just found your channel. Great vids so far
Thanks!
Thanks for sharing and opinion.👍👍
Question. I want to get this sub however I would like to upgrade some parts. I seen on Jacob’s FB page he had his wife upgrade the motor on the New Uv2 with a Zv5 Motor. What would swapping out the motor help with this modification? Also. In addition if I could upgrade the voice coil from 4 layer to 8 layer what would that do to the sub? Thank you for your info. Love your educational videos and I’m a huge fan. Thank you sir 👌🏼
Using a Zv5 motor with Uv2 frame and soft parts kind of creates a hybrid between the two. It may handle a little bit more power due to the bigger motor soaking up more heat. It will also not be as loud on low power but on high power may exceed the Uv2. This is due to the motor structure differences. We will have to see how one plays in Carlos Rodriguez van for verification. Also, the 8 layer coil is more musical, less spl. It weighs a little more, so it lowers the fs on the sub. However, it can add a small bump in power handling, maybe 100-200 more watts overall. I was honestly thinking about a hybrid like this back when I ran my Uv1. Overall, it would be a cool music sub, with a decent spl factor and more power handling. I don't know that it would be that much of an upgrade over a regular Uv2, that sub is a straight crazy beast!
I usually build my subs but I grabbed a couple of the Wlldse U clones because of there ridiculous value, for the first 12 I paid $122! I bought it out of curiosity It showed I checked it out and instantly went order a 2nd but price jumped to $142 but for a 200oz motored 3" copper coil Uv1 frame that's a bargain. Anywho out of the box I tested it and they had an FS of 42 after flexing em for few weeks it dropped to 38 and they were super punchy they crushed double kick drum total rapid punch in the chest but they really were mehh on the low lows which I like also so I laid a ring of old plumbers solder around the original cap and buried it in epoxy then bought a couple of big heavy 7" dust caps too. The solder and cap were 60ish grams of I remember right and it lowered the FS to 31 then with glue 30htz and wow what a difference they hit so much lower and still do kick drum pretty good but with that heavy moving mass there not quite as tight, but the mandatory higher tuning because of my 95 mustang gt convertibles tinsey trunk size there's box size limitations, smaller box smaller port I e. 41htz so there still not killer on low lows but a good all around. People shit on those subs as knockoffs cheap blah blah but value is value, skars somehow gets a pass by the masses and they have ripped sundown off big-time. But I'm not about brand I'm about performance sundowns great and all but a bit pricey. I have about $500 in each of my custom 400oz 15s that's about max for me and bit more than I want to spend but they'll give n X V2 a run but with 3 1" slugs and non bumped t yoke and the DC Audio med to large roll cone I'm probably limited to 3" of x-mech, also I prefer TI frames over the sundown custom tooled frame because I like being able to inspect my coils at a glance the tooled frame is very difficult basically only through that 10mm tall hole vent spacer. I do have a custom 18 I built with the custom tooled 18 frame and I will say it is the absolute strongest frame I've ever seen and I found it having a 12" spider landing cool as hell so I had to source a 12" x 3" spider...$60 very rare and not cheap and I bought an extra but it will probably never get used I was under the impression it was a 3 layer well there a 5, I have a mega roll and that spider and its so stiff with a cab45 I could get about 2" out of it and if I had enough power to get 4" the 3"x3" 8 layer would go thermal fast. Some day it's going to get reconed but it's a shelf queen now. I think I'm going to make a HT sub with it even limited excursion a 1k or 2k PA amp it will shake the house, it was built to be wild and outlandish looking and it worked people online went crazy over it that's why when I built the motor from scratch just pile of steel I used seven 9.25"x .875" slugs. It works good overall and BL was like 24 in series at 4 ohms so it's not crazy high BL but not terrible and it still has an FS in the mid 20s so it does crush the lows bigtime. It just is soooo power hungry to move, when I redo it I'm going just 2 10" spiders so with a 7" deep motor that 4" will be a possible. It's on my RUclips channel "waltzs budget bumping" it's just a hobby channel so I haven't done anything lately even tho I've done a bunch of stuff tho, but I just built A Pillars and starting my door enclosures in my 2010 grand caravan and I'm going wall next so I might do some content especially if I get around to removing my 15" top assemblies and putting 21" top assemblies on my motors it priced out to $650 before tax and shipping for all the parts for 2 they would be better for a just 2 sub wall. Welp sorry for the rambling ,love the channel great tech, box tech is not my strong point and winisd makes my head hurt. I have the TS parameters for my 15s and need someone to do a box design my current box may be ok but maybe not it's 7.5cf 120 SQ" of slot port area tuned to 32htz. Subs up Port up, I wanted to try that over my old subs box that was subs up port back it made my rear hatch rattled bad. Again sorry for rambling on n on lol. Oh yeah... Jk
I tried to look up your channel but couldn't find it, got a link?
Wlldse is hardly a u clone they have a similar basket and that's where it ends
@@SidyDidIt Agreed, from my research, they are about 2 db less sensitive. That is a major gap. However, for those who are not concerned with db, those are still a great budget sub! For those of us who are trying to squeeze every little bit out though.... we know quality. ;)
Are they better than XT 15 in crossfire’s subwoofer
Have you covered pro's and con's of subwoofer installation in a hatchback/compact car?
Nothing like that exactly. I have covered lots of different vehicles but not that one specifically. I will add the idea to my list. Please add you thoughts as well!
@@caraudiolab what I was wondering is, if installing a subwoofer in a hatchback/small truck would act like a 4th/6th order since the compact car/small truck cabin is so small.
@@johnmedrano9782 Oh absolutely. With a ported box, it will act similar to a 6th and with a 4th it will act similar to a 4th. It really depends on the size of your sub box in comparison to your car cabin. The bigger the box, the more it acts like one. However, a hatchback actually can act a little bit like a horn loading enclosure. This is some of what makes a hatchback special!
Good video. It would have been better to do a side by side comparison. The Uv2 is perhaps Sundowns most underrated sub (second only to the NSv5). I would definitely choose the U over the X. Both great subs.
I agree, the U series is my favorite sub of all time. Those who have ran it, they know.
I have an Xv2 15" and Uv1 15" sub that I may pull out some time and compare against each other, maybe even put in a box and test side by side once we get some cooler weather!
@@caraudiolabthat would be an awesome video! Missing the new videos!
@@RandyRossundercaste Just put one out and working on some right now! I have a dozen or so recorded, just need to edit.
Amigo. I’m thinking about hoping on Deaf Bonce 4515R. I want to buy the UV2. I’m having a difficult time choosing between the both lol. One is very costly the other is very efficient and less costly. I would be using a SALT 8K to power which ever sub I go with. Any info helps. Thanks.
Per power, you will be louder with the Uv2 easily. However, with an 8k, you will be prone to blowing one Uv2, that is a ton of power! I have had friends who were hard core Deaf Bonce fans and switch to Sundown. They never looked back, but the 3" coil sundowns can't handle that kind of power. If you never want to worry about blowing a sub, go with the deaf bonse. You can always turn down the amp to 4k and be just as loud with the Uv2 though.
I'm about to put in 2 u v1 12s in my trunk. Really wanting a 150 but would rather it be musical. I was thinking of tuning to 31-32 hz in around 4 cubes net or tuning to 35-36 hz with 4.3 cubes net. Any ideas on db loss and how it would they differ in playing music? Im using an 8inch aero so if I end up not liking it I can retune. Was just seeing what your input would be . Great video by the way!
btw going to be running them on a jp33 @ .5 so should be clamping close to 3k in a 2015 honda accord (box is sub foward port on driver side)
The 35-36 hz would be slightly louder from 35 to 70 (or wherever you set your high pass filter at). The 31-32 would dig slightly lower in the 20's. Personally, I like the U tuned to about 34 hertz. They still give that punch and can play into the mid to upper 20's. You will want at least 4 cubic feet, but can go slightly higher as well, like 4.5 cubic feet. That port combination size with box size should give you good bandwidth and sound good. Let me know how it turns out!
4.5 cubic ft for 2 12?
Great comparison. I have (2) U15 v1 and they sound great even though I messed up on tuning. Meant to tune to 32 but ended up at 38 after all displacement, but still sounds really good. Wish I had 12s though. :)
The U series sub is probably one of the best out there, they get loud on low power! You don't have more room to build the box bigger? The 15's like about 3.5 cubs after displacement (even though Sundown recommends 3).
@@caraudiolab yep, and I they currently have 5.85cf net. Not enough. :(
okay soo i just brought 4 u15 v2 i’m putting in my 66 cadillac…. should i have just gotten the x ???
@@geraldblacher6318no.. just tune your enclosure to 32 hz... them u's are gunna eat that cadillac.
personally, i think the U series is the best all around woofer ever made...
if youre into rebuilding subs, you can customize the soft parts, and bring the fs of the driver down, making it hit the lows better...

@@bdc211 gotcha man !!
I will be goin for dual u10 d4 v2 in sealed enclosure powered by salt-4 .. I designed the box 0.6cuft each (recommended 0.5cuft) should it be ok in 0.6cuft or should i go lower/higher in volume.. Please assist me, i want the sub to hit hard and musical (for daily driving)
The subwoofer will be placed in mpv ( Toyota alphard) most back section of the car facing rear in a tiny space.. The car has been fully soundproofed, mids and tweets are from ct sounds meso and everything seams to got loud with the soundproofing done..
That sounds great! I missed your comment, if you still need help, reach out to me on Facebook Caraudio Lab, just created the page yesterday.
Have you ever took a close look at a crescendo contralto? I got some from a friend of mine but it's hard to find any information on them. I'm pretty sure they're a catalog sub but they look nice
I have heard that some of their subs were catalog subs, not sure about the Crescendo Contralto though. The specs look similar to a U series sub with an 8 layer coil, which is good. Although, unless you know people who have run them, you can't entirely be sure the specs are solid. They are a well liked brand though. I would say you got a good sub though, I bet they are good for music.
@@caraudiolab thank you very much. I'm trying to decide between it, an xv3 12 I own, or buying a stereo integrity SQL 15 and go sealed. I'm just afraid I might be disappointed in the output of the si. My plan was to run the single X in a fourth order or ported. I'm curious if I can get close to the SQ of the SI out of the xv3. I have two American base HD 12s now on an 8K. And they get dumb loud but I'm looking for a little more SQ and trying to decide which sub to run. I've had two sundown sa classic 12s before ported. I just found your videos yesterday and I want to thank you very much for making such great content I know a lot about audio far as installation and electrical but I know nothing about the construction of a subwoofer or TS parameters I'm completely ignorant.
@@850CANE If you already have those, I wouldn't buy the SI, although it is a fantastic sub from people I have talked to. I can say that some people actually run x series sundown subs in SQ competition vehicles. If you are not too worried about space, run a tapered transmission line for that x sub, that would be the flattest bandwidth and sound quality without doing something really unusual, like infinite baffle or something.
@@caraudiolab you're the man! Thank you again! I'll definitely start researching into the t lines.
@@850CANE Maybe I will create a video on it for an easy design. Would 30 hertz and up work? Also what is the longest box you could use? Trying to figure out how many folds it will need.
Sundown uv2 motor force = 188
Sundown xv3 motor force = 149
Hope this helps :)
Thank you for that info! I know Jacob Fuller said that the V2 will be .5 db louder with the same power. I love the U series sub and they are what I run now!
Question: the uv2 12 has an fs of 41hz. Isnt that too high for a daily music sub? Can it still be put in a box tuned to 30 to 32hz?
Yes, you can put it in a box tuned to 30 no problem. You really need a low fs if you have a sub without a lot of motor force. If you had a cheap sub with a high fs, then it wouldn't work as well in a lower tuned box. But, those Uv2's have plenty of motor force.
@caraudiolab thanks for the info. I just got a u12 v2, what kinda box and how much port area should I be using ?
@@akuma4u You can go sealed, ported, 4th or 6th order with those. How much space do you have to work with and what amp are you running?
@caraudiolab jp23 wanna run ported. Looking for a loud as possible but musical that plays everything. 2 net, 16 per, 35hz???
@@akuma4u Stick with 16 per cube for the port, if slotted. Areo ports, you can go down to 12. If you play normal music, example off radio, Pandora, etc, 35 hertz is great! If you want to run rebassed music, you should go down in tuning some, maybe 33 hertz. You will loose a little spl the lower you tune. I would also go slightly bigger with your box. But not over 2.5 cube each. Somewhere in between is great, like 2.25 cubes each. The U's like a slightly bigger box than recommend. I run my 15's at 3.5 instead of 3. That is what most people in the industry recommend.
Check out the b2 rage xl 10s
560oz motors 8 layer flat wound aluminum coils might be better than the uv2s
👍👀👍
So with more throw the X should be windier?
If you play low enough and have enough power to need the extra excursion, then the X will be absolutely windier.
Which is a better daily banger.
Really depends on your goals such as tuning. If you are tuned 30 hertz and under, go with the x, if you are tuned 35 and higher, go with the U. If you are tuned in between, then it comes down to bass preference. I like punchy bass, so the U is great for that. The x doesn't produce that classic punchy sound, you would have to experience it to understand. They are both great for sound quality. Personally, I love the U, one of the best subs out there for sound quality and spl. If you want wind, then the X is great for that with better total excursion.
@caraudiolab I always get my boxes tuned to 32hz. An I really don't listen to rebassed music. Spotify , youtube music premium , pandora and xm radio. Are my daily vibes. So with what you are saying is the U is better.
@@2015gtbass For that, absolutely yes. Especially if you use a 15" sub or 18" sub. The Uv1 are on sale still, most of them. I just purchased 18's for $300 after taxes shipped from directionix online this week. They are clearanced due to the Uv2 subs that are out now. If you use 10" or 12" subs, at 32 hertz, you may consider the x sub if you are willing to spend a little more. However, the Uv1 sub is the best buy on the market right now until they are sold out.
Yeah by looking at how tall the x is, I just never could understand how that you have the same x max
I am going to talk about that exclusively and explain what is going on in part 2. I actually had it recorded and accidently deleted it. So, I just have to re-record it. You can expect it within the next 4 days.
@@caraudiolab great stuff man
@@brockmarquis8511 I just got that video (part 2) uploaded. Let me know if that answers your question! Thanks for watching!
Even though sundown doesn't rec. the X subs. in sealed, they perform Awesome in 4th orders! Windy asf! I know someone who is running 12-15in X's, In a B-pillar 4th order wall, on 12-8ks @ 1/2 ohm per amp!
I have heard that, thanks! I just haven't actually seen a 4th with x subs. Thanks for the feedback!
@@caraudiolabI just looked again, the guy has 12- 8k amps @ 1/2 ohm per amp, ran to 12-15 inch sundown X subwoofers in a 4th order, its like a hurricane, of wind!
@@evilinside5984 Wow! That sounds like so much fun! I think you have given me inspiration to do a video about getting windy!
Much prefer the Xv3 inside a 4th order bandpass. They play everything from 18-60hz extremely well.
I have modeled U subs in a 4th but have never liked the outcome. People always talk about how they are great in a 4th though. I can't say I have ever heard the Xv3's in a 4th. Everyone around here throws them in series 6th order builds.
@@caraudiolab I've built all of the above. U series in 4th orders as well as x V2 up to nightshade 4th orders and 6th orders. U do very well in bandpass situations. 4ths and 6ths. My current personal build is a 6-Zv5 4th order that plays within 3db from 25-55 HZ and plays down to 18hz. Very very efficiently. It's really just all on the end users goal for the setup. Can pretty much achieve whatever you want with traditional platform ( SA and U series) as well as the long throw tooled platform ( x-sddn & team subs) if you know what you're doing.
@@caraudiolab modeling is always off in car audio. Set up hardly ever react the way they do in winIsd
@@DibeezyTheGifted I have never had anything turn out like it models as well. But I like to model to get and idea of how the sub preforms.
@@DibeezyTheGifted I have worked a lot with 6ht, ported and sealed but haven't done much with 4th, just a little paying around.
U series has a 9.5" spider and the X has a 11" spider. I built hybrid U's. Utilized the best of all 3 worlds. Spl surround because of the 9.5" spider, U cones with epoxy and baskets, zv5 spiders with an 8 layer zv5 d1 coils on X v.3 motors . They do phenomenal.
Hi Michael! That sounds like a great combination! I still have to get a demo of those the next time I see you. The last time I had a demo, you were still running deaf bonce subs. Thanks for that feedback!
Most definitely. Definitely much louder now.
Are those parts for the 15 inch? What would I need for parts for a 12?
I got a zv3 12 motor with zv4 drop in with spl surround and black spider currently. Sounds good but missing some low end I think due to the high fs. What would u recommend for a new custom build to get louder and musical?
sundown post alot of technical stuff on their facebook and youtube n tiktok as well
I try to catch their stuff but I am sure I have missed a lot. I am subscribed to Jacob's RUclips channel, he has posted some amazing stuff himself! I always feel like there is so much more to learn!
just found your channel im subbed!👍🏽
Thanks for the sub!
