Maybe they did not sell well.

However the Satin Black is on sale right now. Save $100 on a Dual Drive system, which is basically $20 for shipping over regular price.

My room is a closed 2500 cu.ft. room and in certain scenes in certain movies the impact and extension scare people (the crash scene in Castaway freaked out my kids). Don't get me wrong...One ULS was no slouch but two of them handle EVERYTHING so "effortlessly".

That is great. In that small room:

I really try not to steer people in the wrong direction. I have been doing this hobby for a long time and I also consult in the HT arena and I still believe that a ULS-15 dual drive system is at the top of the class for both HT and music play back. And of course some of the other lucky owners that have a Quad system well just damn.

I am glad you are now in a special club. Need pictures when you can get them.

post #129 of 2712
Yes John, I see you are trying to become the subwoofer king. You still have a way to go before you catch TheEar but your getting close. A very fine system you have and I find it hard that you have to be the only one enjoying it. Maybe the bassheads in this forum can all gtg and come visit your place.
post #130 of 2712
Just watched a rented Terminator Salvation last night. So all I got to watch was the PG-13 version.

BTW Blockbuster what's up with no popup/top menu choices? I stopped the movie to eat dinner and when I came back to it you can't select a chapter to go to. The only choices were audio setup. WTF? I had to manually skip chapters to get back to where I was when I stopped the movie.

Anyway

You got to own this one.

Some of the scenes in this movie have the most intense bass I have ever heard. Better then Ironman, Incredible Hulk and the Transformers movie. This movie will work those 15" drivers harder than any previous movie played on your system. Critics panned this movie but they must not have the same systems we have. The bass was so intense it made watching the movie extremely enjoyable. It really drew you into the movie experience.

In fact all of you bassheads out there, and you know who you are, need to get this movie.

I thought the same... I've got a pair of ULS-15s in a pretty small room and the LFE was "most bodacious".

Off topic, I enjoyed this movie a lot more than Trans2 or GIJ...The other two movies are just a little too busy for my taste.

I haven't had the time to set up a shoot so I could use some flattering light, a wider lens and better composition but since my integrity is being called into question , here's a couple of test shots I did to look at the color balance.

I'm liking the setup keef95. I know the ULS-15's play nice with those Paradigms.

I turned my boss on to the Monitor 9s. They are great sounding speakers. If I hadn't upgraded my crossovers and tweeters in my Klipsch speakers last year, I might have moved to the 11s or signature series. When you get the photography right please post some more.

Peace

Well well well we have another new club member. Welcome Kimwyn. So many questions.

So what was it that convinced you to try a Dual Drive system? I guess, since you said that you where going to pick them up, did you go to HSU for a demo? Was it something you read in your research? What size room are they going into? What veneer did you decide to get?

Keep us updated if you can. And congrats on the new purchase.
post #137 of 2712
Just got tracking order for my new Dual Drive order. How easy is the setup with wireless..etc. if I am not the kind of guy who knows anything about spl meters... etc? Have dedicated room 16x20x10. I figure I should be able to get great performance just with basic adjustments....

I see the club is getting bigger. Let's all welcome Tomtoo.

The wireless setup can be hit or miss depending on your home enviroment. I do not use the wireless feature. My Dual Drive is hardwired. However shadyJ wrote a good setup guide here: http://forum.hsuresearch.com/showthread.php?t=12560

In order to help you with the settings on the sub, please answer the following questions.

What receiver do you own?

What other speakers do you own and what are the main speakers frequency range?

What size woofers are in your main speakers?

In order to get the subs properly intergrated into you system you really want to invest or borrow someones SPL meter.

Also you should read this if you haven't yet: http://www.audioholics.com/tweaks/ge...nnection-guide

Yamaha rx-v3900, and speakers are 12 year old Acoustic Research 315HO. I believe they have 100hZ crossover to dual 5 1/2 midranges. I have no idea how this is all going to sound together. I expect that I will be buying new front towers soon (have beautiful B&W center channel) with more mid bass response.
post #140 of 2712
Ok Tom

I have the rx-v1800 myself.

This would be a good starting point. Set the speakers to small in your Yamaha. Set the volume on the subwoofers to 11:00 and make sure the X-over on the sub is set to out. Set the ULF trim knob midway between the 16Hz and 50Hz setting. Then run YPAO on the Yamaha.

Of course all of these setting can be changed after you play around with them some. I spent 3 weekends moving my 4 subs around and tweaking them manually until I found the optimal settings for my room.

Good luck and let's hear from you again after you get the subs setup.
post #141 of 2712
Will do. Have not tried YPOA program yet. Is this a major engineering task or simple? I assume it just sets the speaker distance and crossover settings.. or more?
post #142 of 2712
It would take to long here to answer your question fully. The simple direction is, read the manual first. Then plug the microphone into the front of the AVR, go into the Yamaha menu and select auto calibration.

I am not a big fan of the YPAO. It does not always work correctly. But I have the tools to do a manual setup. And I have the experience to know when it has not done the calibration properly.

If you want the system to sound the best that it can be, you might need to find help locally or maybe read this entire section while you wait on your delivery:

Of course if you want to pay the airfare I can become available.

I would have to decline, as I suspect you are not a 5'8" blonde bombshell. If I am incorrect, please advise
post #144 of 2712
Are there any other reviews with measurements of performance other than the Secrets review? It seems to show distortion at 100db of over 10% from about 25hz downwards. Maybe that's just the case with most sealed subs (I see the JLF113 had around 12% at 20hz, and the Sub25 less than 10%) but was curious how audible that would be. I currently run my PB13 in 15hz tune which seems to provide much more output with distortion well under 10% even at 15hz if I recall. But was looking to possibly sell that and add dual sealed subs so I can put them up front in my family room theater (about 1700sqft, not a sealed room) and place my Paradigm Sig S2's on top of each sub (as if I stand moun them I can't put subs up front and need to keep it nearfield as I have now which for me isn't optimal due to a null I have in the subs current location).

I recall reading in this thread that dual ULS's would be "equal" in output to one Submersive, but was wondering if that output was at the expense of distortion higher than 10% and where/who measured this? Maybe duals would lower this distortion somewhat I assume.

Somewhat shocked that there are only 5 pages on this ULS 15 sub (and not really that many on the HSU forums either)? Curious as to why that is?
post #145 of 2712
Hi PBC

Here is Pete, who works for HSU response to the distortion in question from the HSU Forum:

Quote:


I'd like to thank Ross Jones and Dr. John Johnson for the great review on the ULS-15 and HB-1 MK2/HC-1 MK2.

Some of you may be wondering why THD was 15% @ 20Hz @ 100db with mic 1 ft away from the cone. In Dr. Johnson's room, at the location where the ULS was placed, notice from the frequency response graph at 1 ft distance that there is a deep bass suckout where 20Hz is 6db down vs 60Hz. This inflates the 3rd order harmonic with a 20Hz test tone, which is what caused THD to be relatively high at that frequency. With outdoor measurements, the ULS would be no more than 1-2db down at 20Hz compared to 60Hz.

In our own demo room, where we don't have a deep bass suckout, THD @ 1ft from the ULS-15 was actually less than 5% @ 20Hz.

So the moral of the story is to use some caution when comparing results from one room to another or to outdoor measurements. In fact, even a small change in position within a given room will mean that data cannot be easily compared between one sub and another. For example, the ULS must be in a different location than the JL subs that Dr. Johnson measured, because there is not a prounced 45Hz suckout on the frequency response graph at 2m distance with the ULS.

P.S.: Even if not directly comparable due to potential differences in positioning, the THD measured from 25-50Hz @ 100db @ 1ft was even less on the ULS-15 compared to the F113 (note that 25-50Hz data is not shown in the review). Also, the frequency response is much more extended than the F113 too.

Two reasons really, they are expensive, therefore most ppl are hesitant to spend that much money on subwoofers. And 2 we are having so much fun with our subs that we don't post much.

I have probably been the most vocal on the merits of these subs. I used to do Ht installs and to me these are some of the best sounding accurate subs I've heard to date. You have probably read the reasons why I went with the HSu over the SubM, so I won't spend time here.

One last thing I would like to add is most of the customers who have bought these subs are not the type of ppl to post on any forum.

If I was you I would try the Dual Drive before selling the Ultra. Hsu does offers a 30 day trial and I would not want you to get the DD and then not be completely happy. You would be going from a ported to a sealed design and as you know they will sound different. Would that be an option? I have no doubt that if you do like them the Ultra would not be up for sale very long.

Hope this helped.
post #146 of 2712
Did HSU write/respond directly to Secrets? I'm somewhat shocked that JEJ would not have mentioned that response in his review. It's the only review I know of that posts measurements of this sub for THD. So most people like myself would simply compare the various JEJ reviews (as he says they're all done in the same rooms/spot and the same way) to get some sense regarding max output at 10% THD. I'm sure he'd post a followup or response from HSU to the review. HSU should really consider this. Especially given how other subs JEJ is measuring in that room have not seem to have this "suck out".

As for Pete's response re: less than 5% at 20hz, was this too at 100db?

Unfortunately I live in Toronto so the 30 day trial is out of the question given the costs of shipping. I think the previous page mentions $3,000 landed for dual ULS-15's, so shipping/brokerage duties would likely be upwards of $300 to $500 in that.

Still surprised at the lack of ownership on AVS and other HT forums. An ID company's best marketing is these forums and HSU seems to have fallen off the face of the map it seems which is unfortunate. The ULS is less expensive than the PB13 and several other options that are available and much more talked about for some reason. If these subs perform as some say they do one would think given the size factor these would be discussed at length and have hundreds of owners talking about their merits, especially on this and other similar forums. Hmmm.

Almost bought the VT3-HO or whatever it was called when it came out but it too never seemed to take off.

Wonder if anyone in the GTA has one or two of these puppies that I can listen to and compare.

I do not know the answer, maybe Pete will be by to answer that question or you could PM him.

That does make a difference on doing a trial.

With your assumption that there is a lack of ownership how does HSU stay in business?

Hsu marketing is probably more magazine based. I have seen their ads in Home Theater and Widescreen Review. I believe they cater more to the HT installation business. That is why I said

As you say there is not alot of postings of their merits but I can say I have never seen a post from anyone who was disappointed with the performance and sell them to get something else. It was one of the reasons that convinced me to buy a Dual Drive system.

When I said expensive I meant when you buy a Dual Drive system or Quad. Unless a single is placed in a small sealed room you really need to get at least a Dual Drive system to get the benefit of output.
post #148 of 2712
So how would these two subs compare, one HSU and one SVS PB 13 ultra in sealed mode? Sound similar, any distinct advantage between one and the other?
I am presently using the SVS (one) and must admit I am intrigued with dual HSU, but just curious about sound quality etc. The SVS is rather large and having two of them in the room would be a stretch, two of the HSU might fit better.
My preferences are clean low distortion accurate. I listen to jazz, classical, electronic and watch blue ray movies at about 50%-50% ratio.
Thank you.
Happy Holidays.
post #149 of 2712
I don't think anyone will be able to field that question because no one who owns a PB13 is going to run it in sealed mode. You don't gain much, but you lose a lot. I don't think that sub was ever seriously intended to be used in sealed mode. I would expect the ULS-15 to have much greater performance in every respect to a sealed PB13.
Also, regarding the above discussion concerning distortion, I would expect the ULS-15 to have much less distortion than say another comparative sealed 15" sub, because of the XBL^2 technology being employed, so I would tend to believe Pete's figures over that of the publication. XBL^2 is a very highly-regarded motor design.

I think in sealed mode the HSU would outperform the SVS for sure, but would love to see some measurements. As you can see here, above 20hz in sealed mode the PB13 is pretty impressive.

It seems to beat out the HSU VTF-3 HO subwoofer almost right across the range in terms of clean output.

Darn I wish Ilkka was still doing these.
