Official HSU ULS-15 Thread - Page 2

post #31 of 2712
Wow, you guys actually listen at reference levels??? That is waaaay too loud for my ears!

The problem with a 1600 ft^3 well-enclosed room is that there may be some frequency response anomalies that may not be present in a deeper room. So even if a single subwoofer can fill the space easily, one may get a significantly better result with multiple subwoofers...

I think the answer to your question lies in the first couple of sentences in post #25 by Pete_Hsu.

Curtis can correct me if I am wrong, but I seem to remember him stating that Reference Level for the LFE channel is 115 db.

People keep trying to point out that each design has its own set of strengths and weaknesses.

Meanwhile, everyone seems to be looking for one sub that has no weaknesses.

Much as I like HSU products, the PB-13 in 15 Hz tune is a very successful compromise between output, extension, and sound quality.

Spyboy did you listen to both subs in the same room?

The list of subwoofers I would like to try in my home includes:

Genelec HTS6
Epic Conquest
Submersive
PB-13
HSU ULS-15
Rythmik 15
Def Tech Trinity
MFW-15
Ed A7-900
Danley TH-50
JTR Captivator
Velodyne DD-18
J L Audio F113
J L Audio F112
J L Audio F212
J L Audio Gotham


There are others, but in-home comparisons are not affordable. If money was not a problem, I could do what several people with more money than I have done and compare whatever I wished to compare.

I am interested in which subs you have compared in the same room, and at the same time, since audio memory is poor.

One of my friend has a sealed room of 1,200 cufeets... We tested my sub in his house....the SPL meter was crazy!

I obtained the same SPL levels,(peaks of 115dbs sometimes, sustained bass over 105) and the same feeling I have in my house with my ULS and A7s-450 pair!

That friend of mine has an VTF2-MK3 in that room and sounds impressive, but the ULS just felt stronger.

No. He is just making things difficult for the ULS... HAHA

He probably hasn't even heard a ULS...

I have 2 ULS-15's in a 1800 cubic foot room. I had a single for a month or so before I went to two. A question was raised, will one hit reference levels? I would like to know how you define reference levels? I don't think anyone actually listens at true reference levels it is much too loud.

With two running level with the mains I regularly hit 116 db peaks on War of the Worlds heat ray scene and Master and Commander canon battle. Master and Commander will just about knock the wind out of you. For music it is awesome, the best thing I can say is that it blends in and you do not notice the sub. It is in no way boomy. I think the % music to movies number is flawed. There is lots of music in movies which is critical to the illusion and plot, every sub must be musical.

A PB13 or PC13 would not really fit in my room and it would look horrible, it is too big for me.

Here is a REW reading in room at the listening position. That's pretty flat and pretty low. This is with Audyssey as an EQ.



Here are the subs without EQ, flat to 5 hz.



Here is a photo of the room


Top quality in my opinion.

So you are siting your expert opinion on this sub vs the Rhythmic but in truth you have not listened to either one.
Why render an opinion on something you have no knowledge of?

It is safe to say this is the SVS forum not the AVS forum. I have come to terms with that.

I'll give you mine...


A7s-450, A7-450, ULS-15, VTF2.3, VTF3.3 Turbo, VTF2, MBM-12,SPL1200R, VLF810,
CHT12R, DD15.

The best in palpable extension, and musicality was the ULS...

What do you mean by palpable extension?
post #47 of 2712
Easy there fellas He actually has a couple VTF-3 HO's and a couple MBM's. and is just expressing interest in wanting to listen to many different subs.

I'd love to be able to listen to every subwoofer, but it's just not realistic. Also, to be a fair comparison, one would need to compare one sub to another in the exact same room. And even then, one subwoofer may work better with one particular crossover frequency, and another subwoofer may work better with another crossover frequency...or one subwoofer may work better with one placement position, and another subwoofer may work better with a different placement position...or one subwoofer may work better in one room size, and another subwoofer may work better with a different room size. And after all that, there are user preferences in play. So there are many different variables to factor in.

It's enough to give one a headache if they think about it too much

Palpable bass...mmmm let's say that my ULS make me feel more some very deep content that even my 3.3 turbo wasn't... So for that ultra low content it is, in my room, adding a little "air sensation presence" that wasn't there before it.
Hard to describe,small, but, it is there...

In the the new Incredible Hulk for example.... When Edward Norton is trapped at the bridge, and is turning into The Hulk when he touches the glass walls of the bridge...You receive a very deep wave...that just isn't as strong with my 3.3 in the same spot.

Thanks,

Many people say they don't need wireless but I like the total lack of wires around the subs. I have jacks in the walls and I truly don't need wireless but I use it.

I also want to get an MBM when wireless is available. On an MBM in my setup wireless is a big deal for my layout.

Any ETA on the MBM? My birthday is in July I have to begin laying the groundwork with the fun police.

SWEET!

That is not a projector is it?

Is that a flat screen LCD or Plasma? If so, what size is it?

Hey Bill,

It looks like Dr. Hsu wants to come out with a more basic MBM for now that has newer finishes and a sealed/ported variable tuning switch. Adding wireless to the unit will require a much more significant board redesign, and will add significant expense to the unit, so he wants to hold off on adding wireless for now. Bummer That said, maybe later down the road you can accomodate one or two more ULS-15's instead

I can't see how more ULS will improve things. My FR is smooth and I have the power. I am sorry to hear that the wireless MBM is not being done now. I could run a wire but wireless would sure be easier.

Thanks for the compliment.

It is an Epson 1080UB, I like it a lot. The Screen is a Stewart Firehawk with a narrow frame option. It stands up to ambient light really well although I can control the light.
If you have a Superbowl party or something like that you want to be able to keep the lights on dim for people coming and going.

We'll see, maybe at some point down the road, we will be able to come out with a wireless MBM. For now, I think there are some aftermarket wireless devices that can be used if necessary.

On the bright side, we should be getting the MBM-12 MK2 sooner than expected, since we don't need to make big changes. I would expect availability within 2-3 months.

Sincerely,
post #56 of 2712
Well my single ULS-15 arrived yesterday. Unfortunately my basement renovation isn't complete yet so for the next week or so it will remain in its box, serving as nothing more than a new perch for the cat. I'll report my thoughts/impressions once I've got everything set up.
post #57 of 2712
I have the ULS-15 Quad Drive and I like my subs. The wireless is a mixed bag. At first I liked the versatility of it but I was getting too much interference with my Bluetooth PS3, my wireless network, Squeezebox etc. I decided just to hook them up the old fashioned way and they sound great. If I were to put them in a custom room I would not use wireless but would run cables to their positions.
