Just use the RCA sub(lfe) in. Thats it. I leave the power switch on auto. Once I set it about a year ago I have never touched it since. It is plugged into the wall through a surge protector and its the only thing on that protector.

Oh well, new one will be here tomorrow!

Well, I'm impressed! I knew the VTF3 MK3 was big, but seeing it is totally blew me away. It does fit in the corner that I was planning on, so I did get my measurement right.

I did a quick adjustment to the system and threw WoTW in. Completely different experience from prior viewings (with my Dayton or the PL200). This time I actually FELT it. If anyone in the PNW finds a little gray/white bobtail cat running scared, please send her home! All the animals were diving for cover. I plan geting the system properly tweaked this weekend, but all I can say is... WOW!

I just got the new amp today and installed it. I put the volume on the new amp to the same lvl I had it last time and its the same lvl my other subwoofer is at. I plugged it in and ran a test tone just to make sure it was function properly and the sub over powered my room. It was extremely loud which surprised me since it was the same setting as last time and as the other subwoofer(also same on the AVR crossover and LVL). I re-ran audyssey from my onkyo 5007 and my other subwoofer is at -3.5 while the one with the new amp is -9.5.

I don't understand why this would be. Both are set up the same, haven't switched places or anything. Previous setups always had this sub at -4 which was only -.5 degrees cooler than the other. Is there a difference in the new amps? Or is this a bad sign about my other subwoofer and its amplifier? I ordered them at the same time.



Sent this to HSU. Maybe they have a way I can test the amp to make sure its receiving and outputting the right amount of power.

Told ya it was big fedex delivered it and my wife txt's me "OMG this box is huge!"

I'm equipping a newly renovated basement. The room is approximately 30' x 14'. Drop ceiling about 7.5' so cubic area is below 3000 cu ft. (Rear of room opens to the right about10 ft.) The screen is at one end and the seating position is at the 14 mark. Rear surround channels will be mounted at that position. Basically, I am using half the room for the seating area.

I bought Energy RC-50 floor standing speakers with a matching center. I need a sub. I'm not sure how a VTF sub will differ from an STF. I've read the description of the difference on the website but I'm not sure it will matter to me since I think the speakers will not need a sub for good bass. Please correct me if I'm wrong. I've only ever had bookshelf speakers to this point.

Will an STF-2 do the job in this room? VTF-1 is $100 more. Do I need it? I like having powerful bass in movies but don't require my brain to rattle.

I'm narrowing down my picks for my system and I believe HSU answers those questions. But more to the point my living room area is 2052 c-ft, w/2 open door ways, kitchen is 1596 c-ft, and bedroom is 1824 c-ft. I have one place only for an VTF-15, and 3 places for 2-VTF3.3'S though that really is more than I'd like to spend. I love movies but music is my passion. Can any of you owners of either make some suggestions? Thanks in advance..........

Has anyone had success using wireless devices such as SubCast, or the AW-1 from Audioengine?

I would like to use one for a VTF3.3.

The Audioengine device appears to be a nice product and respected by those in-the-know.

VTF-15 should work great, that room is not all that large, my one VTF3.3 does fine in my 16x20 room...

Thanks Squeeks... I'm wondering how musical the VTF-15 is over the VTF-3.3, or 2.3's. As I said there's only one place to put the VTF-15 nearfield to the left of my LP.

The VTF-15 is more musical than the 3.3 when in sealed mode. At its ported modes, as the Q control goes higher it is a lot tighter too.

Basically, you can make the VTF-15H' sound as whatever you want it to sound like. This is a great thing!

I just don't want the sound to be localized at the back of my room when playing music.

Don't worry, it is an excellent sub.

as long as you dont have it crossed over at 150hz it shouldnt sound localized...and again, since you can convert it to sealed, it will sound really good for music, i know my 3.3 does

Well, to say for sure that it won't be localized isn't right either. I have my 3.3 nearfield next to the couch on side away from where I sit. Well, it's really a love seat. At first, I had issues with localizing it and then, playing with the settings on the AVR, it was much better. I think you'll have to set it up in your home to really be sure and tuning things afterwards will also be very important.

It seems you're happy with the ability to make those kinds of adjustments--that's good to hear. Everything points to the 15H for me so the more comments like these, the closer I get.

I was looking at the VTF 2 MK3 but I have a question about it. In max extension mode will it still sound good for music too? I wanted to get one but I don't want to keep switching between modes all the time, I just wanted to put it on max extension and be done with it. I'm between a VTF2/3 MK3 and the PC12-NSD at the moment.

The sub will have the same SQ, you will just change the filter applied to the lower freqs. Of course, when you let those lower freqs for the sub to play, the sub will be less dynamic in the higher freqs especially when pushed hard. You can set the sub to either option and be gone with it. It is not necessary to be running it back and forth, but there are people that don't care and do it anyway. You have the option to do what you want.

So how would a VTF-2 or 3 MK3 in max extension mode compare to an SVS PC12-NSD?

I have not heard the pc12-NSD, but a single VTF-3 MK3 is a great bang for the buck. It will competely pressurize your room - unless your room is huge.

You will not be disappointed with the MK3.

Just wanted to say....I finally got a blu ray copy of this movie.......OH MY GOD!!!!!! That part of the movie showed me that my little Stf-2's (got duals and waiting for one more) are able to do WAY more than I thought possible! INCREDIBLE!!!! Thanks for the suggestion INCREDIBLE!!!!!

I don't want to over do it either, my room is only 1100 cubic feet. That's why I was thinking maybe the VTF 2 instead of the 3.

My thoughts are - it's better to have a little more than you need rather than not enough. I recommend the VTF3 100%.

Thanks for your reply, I have another question, wouldn't plugging the ports and raising the Q more localize the sound?

well, like someone else said, you can have 4 subs in a room that size and as long as they are configured right it wont be overkill..so..buy as much sub as you can afford...

never heard the svs, but I have owned 2 of the 3.3's and IMO, that sub is simply amazing...I was getting usable output in the 16hz region with one.

I think that design gets as much performance out of a 12" driver with 350 watts then most boxed subwoofers using the same output.

You also have the option to tune the 3.3 your way, keep both ports open for even more output or use maximum extension with one port plugged... not sure you can do this with the pc12.

I have a mid to large space and couldn't imagine needing more bass than what my VTF-3R provides. A 7 year-old sub with about equal specs to the current VTF2-MK3
Although if I heard a new VTF3, I'm sure I couldn't live without one.

I took delivery of my HSU VTF 3 MK3 last Wednesday and I was finally able to get it dialed in. The sub sounded good at first but it did not sound great. I was getting this annoying pop on low frequencies in movies like War of the Worlds. After messing with the port options and placement I was about to give up, but I stuck with it.

After hearing many great things about the MK3 I knew that the issue had to be user error so I contacted Pete over at HSU. He helped me dial the sub in to where it sounded really good but I still had the pop.

Pete then asked me to toggle the EQ off on my Pioneer 1120 so I did. DING! After turning off the EQ on my receiver this sub kicked me in the chest so hard! It was like I freed the bass god and he began to pressurize my room with glorious deep solid clean bass!

I kid you not, my room felt like it was shifting with the cracks on the floor in War of the Worlds chapter 5. Iron Man 2 was INSANE and most importantly the pop was gone!

My biggest advice I can give is cut off the EQ so you can see how it sounds before the signal is touched. I am running it with both ports open in 25hz mode. The sub volume is set to 1.5 and the receiver SW level is -1. At this level my room is totally covered with the MK3.

I have a way more expensive sub from a well known sub company in my main home theater and I am thinking of selling it and getting a HSU ULS-15 to replace it.

Here are some picks of the sub in my gaming room.

Thanks Pete and everyone here who helped me pick out such a awesome sub. I really wish people can audition these subs because there will be no way you would leave without buying it.

I'm surprise to hear this, what is your crossover set at? The 1120 only does sub distance and gain, no eq of the sub. Does turning the eq off also disable the amp's crossover, giving control to the sub's crossover? I'm interested in the 3.3 and your room looks significantly smaller than mine.

Not sure what it does exactly. I heard that the EQ tries to boost some low frequencies causing more stress but I could be wrong. My crossover is being handled by the receiver and it is set to 80.

Whatever the pio EQ is doing it is affecting the sub in a bad way. I was just happy that shutting it off fixed it. To verify I switched to my Denon and used audyssey and I did not have any of the pop issues.

The sub is fantastic connected to the Denon /w EQ on and off. It also sounds fantastic connected to the Pio with the EQ off.

The reason I checked on the Denon was to verify that it was not the sub causing the issue; it is indeed the 1120's EQ.
