Uls-15

[ryounglaw]

Tell me about them, I have a 4200 cu foot room, townhouse and will use it for 99% HT. My other options are the PB13 Ultra and the PB12+. I have not heard a lot about the ULS 15. School me. I like the wireless idea.
Thanks

Weren't you previously deciding on a LFM-1 EX's against a PB13-Ultra?

I would say you need at least 2 subwoofers for a 4200 cu ft room.

 

[ryounglaw]

I can't make up my mind. Its a lot of money and i want to get it right the first time. thanks for the advice

I can tell you I wouldnt want to be your neighbor if your connected with common walls but then again if you get two subs you might not be connected for long so My votes for two subs

 

[blued888]

Get dual subwoofers.

I say go dual PB13-Ultra's or dual ULS-15's and be done with it!

Who agrees with me?

 

[Chopin_Guy]

The reviews I have read of the ULS suggest that dual units is the starting place for best performance---especially in a room in the size range of yours. You could even go with the quad setup if you wanted....

I know that two ULS subs or two Ultra 13s doesn't seem to be in the price range you are looking at given all your discussions about your sub choice. The Ultra will outperform the ULS and I will attach two reviews of each tested within the same parameters and you can see the bench-test results of the two. For example the ULS-15 has 15.5% THD with the 20hz sine wave....where as the Ultra-13 with the 20hz sine wave had 6.03%--BIG difference and the Ultra-13 still does much better at 15hz with only 7.9%....

You have already been told about everything you can when considering your subwoofer decision....the Ultra-13 will give you the most performance in your price range. For a little more and if you feel like you need the even more then you could go with an Epik Conquest. But the Ultra is a much more practical unit in anyones space. And if you want the MOST then DIY......

Just curious questions

How tall is your room ? and what is the sq ft layout. The only reason i ask is I have an open room, my den that is bacially a square 20 x 20 x 10 ft high which is about 4000 cu ft. And Yes I know square is bad acoustically but don't worry sound position take care of, and have some acoustic treatment, and actually listening distance is much closer 10-12 ft.

The reason I ask and not that I have any thing against the PB13-Ultra or SVS at all. I have a single SVS PB12-Plus and it drives my room perfectly ( not to say that PB13-Ultra would be more perfect ) I am just wondering out loud if two SVS PB12-Plus would provide you an excelent level of sound at a lower cost?

Okay I was just wondering and since you are set on two, larger PB13-Ultras I am corious did you ever consider a single JBL 113f FATHOM which would be about the same price?

Good luck!

P.S. - I know you said PB13 and PB12+, but if possible and iti is not always possible, but in your case it appears to be possible, if you have mutiple subs, it is best if they are identical.

P.S.S. - Thought my wife was going to die laughing last night. Her sister called and my wife told her I was relocating my sub and her sister said "What is the matter isn't it loud enough ? I guess some people just don't apprecaite the sound of a great sub

I really LOVE my ULS-15 Mk2 subwoofer! It does music and home theater very well -- and paired off with the Von Schweikert VR-5 HSE speaker (and the LampizatOr Lite 7 DAC), no less!

It's especially good at rounding out the lows with live rock and blues, but does equally well with jazz. And HD TV drama/action? It's very, very good.

I'll be publishing a review on the ULS-15 in a few weeks, so I'm pretty familiar with them. It's proven to be a great subwoofer, but 1 won't be sufficient for a room that size. Realistically you would need a pair.

 

[KEW]

You are responding to a post from 2009, but good to hear you will review them. You'll review the new Mk II version, right?

 

[theJman]

Actually, I was responding to a post from Friday - the one above mine - but I never looked back further than that!

LOL! You actually included a post from 2009 in your post, but its all good!
Looking forward to your comments on the Mk2.
Wish you had the original to compare it to to see what Hsu did with it. The original ULS-15 was getting "long of tooth" but was a major contribution to the subwoofers available when it was introduced!

The ULS-15 mk1 was and still is a very good sub. The driver in it is the real deal, a XBL^2 design with triple copper shorting rings, extremely linear with a healthy amount of throw. It would be a very expensive driver if it were sold itself. I also liked the way the ULF Trim was handled in the original. The original ULS-15 was an ideal system for getting very low distortion deep bass and a flat frequency response throughout the room. The new ULS looks good, but there are things about the old one I like better.

Lets make it easy!

http://www.ayllonmedia.com/1/post/2015/10/does-the-hsu-fit-a-look-at-the-uls-15-mk2-subwoofer.html

$850 (shipped) is a nice price decrease (especially if it doesn't give up any performance). For a well built 15" sealed sub, it is nicely capturing the price point PSA left open when they discontinued the XS15se. But, then again, PSA said no one was buying the XS15se because they all wanted to upgrade to the $1,000 S1500 (which I think is the ULS-15 mk2's closest competition).

Juan,
Enjoyed scanning through your review!
Some of the information in your review is incorrect.
Your experts told you wrong, the XLR connection is the best (less prone to interference), followed by the line-level (the most commonly used connection), and the speaker level connectors are last (because of possible compromise to the signal going to your mains). It may be that none of these is audible, but if the XLR or line-level is easy to use, there is no good reason to use the speaker levels. Glad you followed Hsu's advice on that!
Also, you say the ULS shares the driver with the VHF, but I don't believe that is true. Hsu says they share the same motor structure, but it would be generally unwise to select the same driver for a ported model and a sealed model.
That said, I enjoyed reading your review and hope you continue to add to the compilation of information on audio gear.

You are indeed correct Kurt; Dr. Hsu personally told me they share elements but the drivers are not the same.

 

[Juan C. Ayllon]

Thanks, Kurt! I appreciate the feedback and complements. What's also cool is that if you go to Hsu Research's site, click on the ULS-15 Mk2 tab and scroll down to the bottom of that page, you'll see that they quoted excerpts from my review and posted a link to it, as well. How cool is that?

Have a great weekend, my friend,



Juan
