HSU Research ULS-15 MK2

By Jim Wilson (theJman)

Taken as a whole, the HSU Research ULS-15 MK2 may be the best value going in the 15" subwoofer market. At less than $850 shipped it represents an amazing bargain, yet it's not just the low price that makes it stand out. This subwoofer was executed to near perfection by HSU; from its appearance to the obvious attention to detail - and of course the magnificent sound quality - they nailed every aspect. You realistically couldn't ask for more from a subwoofer that costs what this one does. With all the changes the company has recently made to their product line it seems HSU Research may have grown weary of being an also-ran in the ID (Internet Direct) market. It's evident they want to be on top of the heap now, and if my experience with the ULS-15 MK2 is any indication they have every right to be. Make sure HSU is on your short list the next time you go shopping for subwoofers. You can thank me later.

Re: HSU Research ULS-15 MK2 Discussion Thread

As a HSU VTF-15H MK2 owner I will say this. My sub is stupid big for a 15". Had this been out I would of likely bought it instead. 18" cube is excellent for a 15" driver.

all three subwoofers are identical (VTF-15H MK2, ULS-15 MK2, VTF-3 MK5 HP) It's nice to see enclosure options. Completely sealed small size. Ported midsize and large size (mine).

I love mine I really do. I want to try PSA out but my sub leaves nothing to desire. I just want to add a second to take advantage of the XMC stereo subwoofer capability and have better room response across my couch listening space.

Good review btw.

Why not two?

What surprises me is their flat to 20hz claim when the other subs when sealed and in EQ1 fall off from ~40hz. This ULS has 5db more output at 20hz than the VTF-15H MK2 that I own when sealed and in EQ1. Is it being my enclosure is too big for sealed? I know mine was made more for ported w/ the ability to seal but thats a pretty significant hit. Although 1 port open and mine is 6db louder at 16hz compared to the ULS. Of course this is comparing the charts.

And then you factor in the price. Dual ULS-15 mk2 for 1640 shipped is a crazy good price especially since it's the same driver/amp as mine where dual mine are $2016 shipped.

I'd love to see/hear what dual ULS's could do in my room. Unfortunately I already own the bigger box version so economically adding second is all I need to do.

Hi Jim, how does the ULS-15 MK2 compares to the subs you already reviewed, the Rythmik E15 and the SVS SB-13 for both movies and (music) sound quality? Thanks.

Well now that you mention it Tally !!!
Actually, as with many things in our life, it is a matter of money, nothing more or less, just plain old cash.
I have it on my Christmas list and I will of course have to throw some cash in the bowl for my wife to buy it so my other subs will have to go on the for sale block.

Good Listening

The SB-13 is an over-achiever, no question there, but with a 13.5" driver it is at a bit of a disadvantage to the others with their 15" drivers. It can hang with the two of them for the most part, so if you don't push things to the limit it certainly is a good choice. The E15 is still my favorite among the three, but the ULS-15 is a real close second. Think 1a and 1b instead of 1 and 2. The best part is none of them is a bad choice; no matter which you went with you'd end up being happy. It's just which fits best for a particular situation.

Re: HSU Research ULS-15 MK2 Discussion Thread

Jman! As usual I thoroughly enjoyed your review. I have a question however, about when you reference things like absurd levels, or painful levels(sorry for the paraphrase) etc. The reason I ask is, everyone has a different threshold. More than that though, for example in my system MV-20 is my baseline. This is quite loud but not to where I worry about hurting my subs. I'll adjust accordingly depending on mood, company etc. I understand due to speaker sensitivity differences and room size differences it might not be a lateral comparison, but I wonder if it would be worth noting relative volume levels for comparison. Or even what the values are on your spl meter during such passages. Btw, I enjoyed your inclusion of Dave Grohls attributes. As a drummer who plays guitar and sings, that was nice to see. I also love AIC's dirt. I have a promo copy of "Jar of flies" that has little plastic flies in the spine.
