Maybe because there's other sealed subs that offer the same performance for a lot less money.

this and currently even with the uls15 on sale it still cost 1124.00 shipped. If I am spending that coin I would be getting a xs30 instead for another 25.00. being the psa has twice the cone surface and double the rms power i would expect quite a significant output adavantage and deeper extension. of course this is speculation based on what info is qvailable between the 2.

According to their respective product pages:

- the PSA XS30 has a 725W RMS amp; and

- the HSU ULS-15 has a 1000W RMS amp.


-- Edit --

Hmmm...just noticed that the HSU's RMS power is "short-term". I checked the owner's manual, but it has the same spec.

short term is not rms, that peak.

Well, if you're in the market for a sealed 15" sub then there are better options. Unless you're only concern is space limitation, in which case the HSU would be a good place to look.


As mentioned before, most looking to buy a sealed 15" setup could/should look to the PSA XS30.


At the same time though, it's extremely easy to build a sealed 15" setup now considering you can buy pre-made flat pack enclosures. You can build an equivalent sealed 15" setup for under $600 now. That includes the driver, amp, enclosure kit, and any extra pieces you may need.


So for the price of a single HSU ULS-15 you can either pick up a PSA XS30 or build two sealed 15"s and power it easily with an iNuke3000dsp.

Yup - that's why I updated my post.
I wonder why they didn't list the "continuous" RMS spec, like they do for their other subs.

Maybe they were afraid it would look weak. It's a bit strange that HSU would withhold information like that though, just to ensure it would keep selling.

Yeah. And really if you can pick up the flat pack it's barely DIY. The hard part is designing the enclosure, cutting the wood, and building it. Most of that is done for you now.

Part of the reason I didnt buy subs from them...also back in 2008 pete said the new website was going to include measurement numbers with all subs. 5yrs later I have yet to see any unless Im looking in the wrong spot?

The ULS 15 is for when you want lots of output and high sound quality from a sub that can go into a lot more places because of the smaller size, higher WAF, and wireless connectivity (I use my ULS-15s as desktop speakers). You can get get more output from larger subs for roughly the same price. The output level can be roughly that of a VTF3, so it is not shy in loudness. It has other features such as a ULF Trim, XLR inputs, and a pretty serious XBL^2 driver, so it's a pretty deluxe sealed 15". If you want substantially better from a sealed 15", you have to move up quite a bit in price range, up to a Velodyne DD15 or Paradigm Sub 25. I think the continuous RMS power is somewhere between 500 and 600 watts, my guess is 550.

Or you can build a pair of sealed Ultimax 15"s for less than the cost of the ULS-15, and have equal or better SQ, better in room response, and much higher output levels. Only thing lacking here is the more compact size of the ULS-15 and wireless connectivity. Really, you can get more output from larger subs at less than half the price. I'm thinking that a sealed Ultimax 15" alone would best the ULS-15. Wish someone could do actual comparisons here though.


It seems the ULS-15's selling point is it's small size and high WAF.

You can always build a more powerful sub than whatever is on the market... if you have the tools and the woodworking skills. Don't forget that many of the subs on the market isn't just slapping a driver in a box and connecting them to a amp. You get a nice finish, you get built-in limiters and equalization, and all the features and connectivity that the ULS has. If you added all that into your DIY project, the costs do mount. This is all neglecting the costs in time as well. The ULS-15 is a bargain if you would rather skip that project. This argument has been done to death against the JL Audio subs too.

But with flat-packs the design work is literally done for you. All you have to do is glue the pieces together, clamp them down, then finish them however you like. Commercial subs aren't the only subs that can have impressive finishes. It takes time and work, but alot of people in DIY enjoy it. You could literally buy every tool you need to build your own box, and still come out under the cost of the ULS-15.


Most subs on the market are just drivers thrown in boxes connected to an amp. They usually have paper veneer finishes and high tunes. The minority of higher quality commercial subs are the one's you're talking about. Where companies take their time to actually design the subwoofers from the driver to the amp and add beautiful finishes.


The iNuke3000dsp would provide tons of power and the ability to eq specifically to your room's response. Rather than getting a pre-eq'd sub, you now can tune it to sound it's best in your room. Throw in some measuring gear and you're still under budget.


I'm not saying the ULS-15 isn't impressive, because it is. I'm just trying to say that I think the ULS-15 isn't mentioned much on here because there are other options that usually come up first. Most people are Ok with a larger sub and aren't space limited, so the ULS-15 is sometimes pushed to the side.

In my opinion, the short version, the ULS-15 lacks value for what you get.

This is one way to put it.


But I think it really just lacks what many people value the most. High output low frequency extension for a reasonable price. This subwoofer is built for people who value the compact size, functionality, and WAF, the most.

I don't know what subs you own, but unless they are well executed DIY subs, they are not likely to be any better of a value.
