The Official HSU VTF-15H Thread - Page 14

Congrats on ordering the 15H. You're really in for a treat. Make sure you let us know your impressions when it arrives.

We have CEA-2010 data on every SVS model with the new amps. We will be adding that to our website. But I don't want to sidetrack this thread - it's about Hsu's new product and not about SVS.

I've got hundreds of hours logged with Keele's 2010 program and I know exactly how Ilkka generated his data. Since there was a lot of initial discussion about the CEA-2010 output values, and there was some confusion about Ilkka's data in particular, I wanted to clarify how to obtain 1M GP Peak equivalent values from Ilkka's data. There is no "estimation" - add 6 dB for the distance changing from 2M to 1M, and add 3 dB to convert from RMS to Peak. This applies to every sub he tested, including other Hsu products too and not just SVS products.

I won't post again in this thread out of respect for Hsu and their product launch. All the best, Pete.

Yesterday, I watched LOTR3(Battle of pelennor fields) and Spiderman3(chapter 6 I think...) and I registered 117dbs uncorrected peak values, at listening position, with Radio Shack analogue meter....Impressive!

It sounded clean, extremely tight, and appeared to have more in the tank to offer...

While Im sure it can do more(couple more of clean dbs)...I didn't want to push it more, I really value this subwoofer... so, no need to break it.
Excellent SPL monster sub!

This was with two ports open, Q @.5, volume at receiver -12, LFE level at 0, level at sub about 9'o clock...(11-12 feet listening position in a 3,100cufeet room)

I also tried it with This is It Blu-ray, and it really sounds like a sealed sub(very tight), not "boxy", even in the ported config with two ports open.WOW!

Sounds like two VTF-15h's would be overkill. Perfect!

HAHHHAA. Exactly.

What amazes me more is that, even with the A7s-450, I didn't had that SPL at midbass/upperbass(and it was an SPL monster at those freqs)...and that is a big sealed sub, with an 1,300watt RMS amp, an 18" driver with 22+- XMAX...I mean wow!

It is far more powerful than the MBM-12 in the midbass/upperbass...

That's not what I wanted to hear. I was thinking about adding an MBM-12 to my VTF-3 MK3 but I just keep getting drawn back to the 15H

What to do, what to do...

My VFT-15 should be here Friday. So I'm open to suggestion demos. Anybody want to recommend how to show this off?

^^^now that is the statement i didnt want to hear....... Pete, what do you think of that?

HAHAHAHA.... Kimwyn...I'd knew you''ll jump out...
I was just playing you!!!HAHAHA
Nah, seriously...
It really feels more powerful, and tighter in the midbass/upperbass than the MBM does The A7s-450 was a closer match to the output of the VTF-15H in midbass/upperbass...But the VTF-15H wins.

If your room has high deep bass gain...both ports open, EQ2, Q at .3, 9 o'clock volume setting...enjoy!

The MBM-12 is extremely powerful for a 12" driver in a compact box....but.... bigger subs are bigger subs...

Anyway, when I had the 3.3 and I added the MBM-12, the system sounded excellent! Night and day difference!

So, I think you won't lose with either option you choose...

Take a look at this thread: http://www.avsforum.com/avs-vb/showt...55493&page=171


Recent favorites for bass include How To Train Your Dragon, The Last Airbender, Jonah Hex, and Iron Man 2.

Did you have the MBM-12 nearfield and the 3.3 farfield? If so, does the 15H, in your opinion, outperform the combination? I have the 3.3 about 12' away from my LP at the moment and I don't really get that thump in the chest I'm looking for. I was hoping a nearfield MBM-12 would help with that. Just trying to figure out what the best option is.

This decision was so easy...until they went and announced this beast.

Thats exactly how i feel and i have a dual drive. i bought the second ULS the during the week they announced the VTF-15H.....

I had the 3.3 with the MBM, in the farfield, nearfield, just everywhere....

As i see it...

The VTF-15 H feels more powerful than the combination....YES, it does!
Dual 3.3 +MBM = VTF-15H ...very close call
Dual 3.3 and dual MBM will outperform the VTF-15H...YES!

seeing this thread and reading thru it makes me wonder what my second sub will be in the future. epik doesn't make the sentinel anymore which is what i have. i love the sub's triangular ports though. darn sexy and innovative and 15 inches too. besides the mid bass being really excellent on this, how is the low end?

I've done a good bit of testing/playing with the low end. I originally had a house curve built in but now have it EQ-ed with the BFD flat down to 16Hz with both ports open, Q=0.5.

If I switch to 1 port plugged and EQ1, Q=0.7 it's flat to just below 12Hz. The sub has plenty of extension.

Looks like I am joining the Hsu family, I just ordered VTF-15H. Merry Christmas and Happy Birthday to me.

Now my sleepless nights begin until it arrives!!!!!!!!

I just got mine this morning so I can say it will be your neighbors with sleepless nights after you get yours if you watch any late night movies.

The low end is incredibly good too. But not surprising, because it is a HSU big ported sub. What is really amazing is how powerful it is in the midbass/upperbass given that it is a ported sub with just the right amount of amp power...!

I still can't believe how this sub with "only" 350wrms sounds like this...
That driver has to be very very efficient...I read somewhere that the 3.3 had 90-91db of sensitivity, but this has to have much better sensitivity...

I wonder how this compares to my Empire with music. I just watched Changeling(Jolie/Eastwood) and the shock scenes in the mental hospital made me want to go over and hug my Empire. I miss the low end from my SVS PC12-Ultra once in a blue moon. This sounds like it could be the ultimate combination of their strengths. I am hoping for a comparison.

Also, I am glad that the design is along the lines of what Chad did with Empire as far as efficiency. People said the same thing about the 600 rating for the Empire, even being sealed, but the thing rocks. So much for overpriced 5000 watts subs. Well done HSU. Now I just need to avoid reading the gushing reviews on this thread.

It really is amazing how they were able to get so much mid bass and still get so much strong low bass as well and yet still produce a sub that is so tight and great with music. IMO having the Q control is a great idea because it allows you to tune the sub to your liking and then just leave it there. The sub does so many things well. It hits really hard and digs deep even with both ports open(16Hz) and still has great mid bass. Or you can plug a port and dig even deeper and only give up a little mid bass. I know there's always trade offs but IMO this sub is the right combination.

Ed has made some respectable posts in this thread, but I'm still a little shocked at the lack of speculative comparison to this sub and the PB13 given the numbers and price difference.

*I'm a very happy Ultra owner, but you never stop looking at subs. Ever.

It appears to be an exceptional sub. I prior standard for music was a VTF3 MK2. I always found the HSU subs to be more musical than the SVS subs. The Empire will have to be ripped from my grasp. It is that detailed and that powerful. Also, I am wondering if one can set the knobs on the back(Q control etc) and forget it or would I have to change tunings for different material?

Yes you use the Q control to find your sweet spot, then set it and forget it. Over the past week I experimented with several Q settings with 1 port open, EQ1 and EQ2 as well as two ports open EQ2. My sweet spot is two ports open Q=0.5. Now I never touch it It stays there for CDs, concert DVD & BDs, movies & TV.

I am no pro but I would be shocked if this sub bests the Ultra in sheer output. However, with the price, tuning flexibility, and bass detail expressed here it is indeed an unbeatable value. Imagine that you can get 2 of these subs for almost the price of an Ultra. That is hard to beat, especially if it as musical as other HSU subs.

I've tried pretty much the same settings over the past few days adjusting the Q settings and it's really tough to say what I like better between Max Headroom(1 port/EQ 2 with the Q setting at 0.3) or Max Output (both ports open with the Q setting at 0.5) like you have it. I haven't even tried sealed yet and don't find a need to - the bass is clean with one or both ports open. They both work well for music and movies but seems like more material suits the Max Output Mode. I got the sub gain at 9'o clock and my receiver is at -7.0 and don't want to raise either any higher than that. My wife has already complained a few times thinking my neighbors might come knocking.

What setting do some of you other owners have it at?

I use max output with Q at 0.3 and I leave it there most of the time for TV, movies, and music. Even with both ports open this sub sounds good with music. However, if I really want to clean things up and want the best match with my mains for music, I run it on sealed maximum extension with Q set at 0.5.

If you haven't tried sealed mode give it a shot. Its actually pretty cool being able to hear how plugging up the ports tightens and cleans what is already good sounding bass.
