Would this be the first one in the wild?

I think someone at the open house bought one.

Pictures! Sorry terrible quality from terrible camera and even worse photographer, pictures taking is not my thing but I thought that maybe a few of you would want to see some pics. Camera died before I finished speaker and sub final placement (moved lcr up to match depth of this monster).

Audyssey 2eq run on THX Onkyo reciever with sub bumped to +2 db hot. Sub 9:00 Q.5 ports open and firing. I don't have any measurement equipment now, hopefully soon but DIY acoustic panels up next before that purchase. Just finished watching WOTW at -8 and whoa!!!! Zero port noise (home run on new design) and I never could tell the 1400w burst was running out at any extended bass scene. Just clean, smooth, hard hitting bass jumping into the bones. Mine is also signed by the good ol' Doc on amp and is a great personal touch to an awesome bang for the buck sub. Huge thank you to Dr. HSU, Pete, and everyone else at HSU Research. Also got in 12 gauge monoprice wire to run to fronts and a new center channel stand today that I put together and got this beast from garage to basement by myself. I am beat and going back to enjoy the new toy! I will check in tomorrow, hope someone enjoys pics and I again apologize for the crappy quality.

Assuming equal efficiency as the PB13 (who knows, it may be higher because of the bigger woofer), if the HSU amp can manage as much short-term power as the SVS, then it should make about the same numbers.
In general I am always very wary about comparing different data sets. There are many different variables involved, even when looking at CEA2010 data. For example, does one use single tone bursts or an averaging of tone bursts? Was there a fudge factor to convert the CEA2010 peak output to RMS output? Does one measure with the subwoofer in normal orientation or a different orientation?

Our measurement procedure is as follows:

We place the subwoofer in the middle of a parking lot. We use Beta 1.62 version of the CEA2010 software developed by Don Keele. We use a TES 1356 SPL Calibrator to calibrate the mic (Earthworks M30) before each test. We use the Pre-pro mic preamp, the same one that Don Keele uses. We do not use any fudge factor. We place the subwoofer in the normal upright position as suggested in the CEA2010, place the mic on the floor directly in front of the front baffle, 1 m from the woofer dust cap. We then test up to the highest level without hitting 'fail'. We do not use averaging.

So the reality is that our data is not directly comparable to any other data set that is gathered without using the exact same test procedures that we do. We believe in the validity of our methodology, but we do have to be careful about making extrapolations.

Sincerely,

Hook the sub up to the TV in the background :-)

Looks fantastic Luke, what a nice home theater you have there, congrats! Thank you for everything, please enjoy!

Hey Luke! Glad that you got your sub too! Enjoy, man!

1. Keep the 2 HO's and add a VTF-15H
2. Sell the 2 HO's and get dual VTF-15H's

Thanks

I think you should start by adding one VTF-15H. Assuming that you are very happy with it, then the next step would be to sell the HO's and get another VTF-15H. That's not to say that mixing and matching can't work, but results are more predictable when using identical true subwoofers.

A couple VTF-15H will fill this space really nicely. Should make for a huge upgrade!

Sincerely,

The VTF-15H in it's normal orientation without feet is exactly 25" tall, and exactly 26" tall with feet. If that ends up cutting things to close, then putting the unit on it's side is just fine too!

Good suggestion! The Satin Black finish is actually much less reflective than any Piano Gloss Black finish, so with the lights dim it should work nicely.

Just a heads up everyone, we recently added a VTF-15H Quick-Setup Guide and VTF-15H Owner's Guide to our website. These are listed as a *.pdf file in the lower right hand corner of the VTF-15H product page.

The Owner's Guide is actually the Owner's Manual (yes, even though rare nowadays, we did provide an Owner's Manual!!!), and provides some details on placement, settings, operating modes, Q control, etc.

Sincerely,
post #229 of 5101
I look forward to anyone who has had experience with JL F112 subs that move to this unit for two channel. I currently have a pair and have contemplating a change. Was looking at a pair of Empire of Quad Legends.

I am incredibly happy with my JL and am awaiting for impressions of the SB12 as well. Concern with the SVS is output above 20hz in comparison to the JL though.

Also, what finishes if any are in the pipeline on this sub?
post #230 of 5101
True subwoofer with an attitude. Very dynamic, fills in the sound beautifully then bam, right there in the thick of it when called upon. I feel it plays everything exactly like the soundtrack asks of it. Excellent home theater subwoofer and from the little music I have listened to it is no slouch in that department. Thats it for me, I will leave the rest of the reviews to the pros as I am just an enthusiast in the audio department and don't have the proper measurement equipment or years of knowledge and comparisons that many members of the forum have. I am once again extremely satisfied and look forward to seeing how others feel!

If anyone wants to discuss anything just shoot me a pm as I don't want to derail thread. Thanks for the suggestion shadyJ, just got back from fabric store with a yard of black velvet and works great!

Sincerely,

I have a rather large open family room as my HT. (15x20x12 vaulted and opens to kitchen). Placement would be best sideways with 26 inch side facing the listening area. Other options can be accommodated but this would be ideal if it is a realistic option.

Sincerely,

My old Hsu had the Piano Glass Black finish and my VTF 15 is satin black. They are nothing alike. The VTF 15 isn't very reflective at all.

Hey Luke,

Sounds like you are just as happy as I am! Congrats and enjoy!

This thing looks great and sounds like it is awesome. I am wondering how this thing will stack up against the new Velodyne DD-15 Plus Sub. I am in the market for a pair of subs but never bought a ID sub before. I have been looking at the Epik Empires, svs, ed's & rythmiks. I have one question, how come only a 350 watt amp in this unit?
post #235 of 5101
350 watts is plenty for this unit. It all goes into the design, driver, and effeciency. This product was developed for over 2 years so I assume Dr. Hsu has the power plus enclosure size characteristics down to a science.

It doesn't matter.

It could be 5 watts and that wouldn't matter. All that matters is the performance, and one aspect of performance is the output numbers that have been posted. If those numbers are even close to accurate, this sub has very impressive output and compares extremely favorable to the subs from the other manufacturer's that you mention.

Thanks Pete. Once I purchase one if I don't have too much trouble calibrating them together I may just keep all 3, but we will see.

I've seen the sub before, so I can say that is a big shepherd!
post #240 of 5101
She is a large female 85lb Shepherd. The sub is not small by any means, but a small sub wasn't what I was looking for. Pic for comparison and to show two large animals that are very gentle but do have a loud bark and a strong bite!
