The Official HSU VTF-15H Thread - Page 130

post #3871 of 5093
Placed an order for the VTF-15H on Tuesday, got the Fedex tracking that it should be arriving this Friday. Pretty excited. My current sub is an STF-2 that I purchased about 2 years ago now. The STF-2 is a really good sub and I'm sure it will sound even better in my upstairs closed in game room but right now in my living room that is open on one side to my kitchen and one of the other sides is separated by the stair case, I think it just a little too small for the area. Its a pretty open layout. My wife thinks the STF-2 is more than enough and thinks I'm crazy for wanting a bigger sub lol. Can't wait til it gets here. I plan on taking the day off Friday to try set it up. The rest of my system consists of Polk speakers...Monitor 60s (front L/R), Monitor 40s (side surrounds), CS2 center, and RM8s as rear surrounds, Denon AVR 891.

I've been reading up on the initial settings so this thread has been very helpful. I'm sure I'll have some question though on getting it set up right. Dr. Hsu was really great at helping out with setting up the STF-2 and that was part of the reason I stuck with HSU. You can't beat great customer service and a great product.

Here is a sketch of my first floor layout where the sub will be getting used. The STF-2 is in the corner as shown, will that be a good place for the 15H? There is plenty of room there. My favorite sitting spot is in the center of the couch directly in front of the tv.

That should be a great position for the sub. Set it to two ports open, EQ2, Q=0.3 to start. Your room should have excellent support at 16 Hz and 20 Hz.

Hate to let this bad boy go but too much fighting with the wife over this monster.

Not a scratch on it and only nine months old with five year electronic and seven year manufacturer warranty:

Man with Father's day right around the corner that is very tempting. If I still lived in SoCal I would want this! GLWS!

Great, thanks Dr. Hsu. It is out for delivery right now. Can't wait for it to get here.

Hi xavb,

Congrats on your new VTF-15H! Welcome to the Hsu Family. biggrin.gif

So I don't have an SPL meter but just did Audessey MultEq set up with the sub at 9 oclock on volume, EQ1, 1 Port open, Q7, Crossover all the way up, and EQ set to out. It set the sub at -5.0 in the trim levels in the AVR. Is that ok, or should I adjust to get it to +-3.0?
post #3888 of 5093
-5 is fine, but you can shoot for -3 to +3 by adjusting the sub knob and rerunning. I boost my trim level by 4 in the AVR after I run audyssey, so I shoot for around -4 or -5 so its close to zero after boosting.

Exactly what I do. -5 db after auddysey then to 0 db.

-5.0dB is about average for Audyssey.

I would avoid running your sub hot, because that's an excellent way to shorten the life of your amplifier
and put unnecessary stress on the internal parts of your sub.

Audyssey set the levels of my front subs at -2.0dB and my rear subs at -4.0dB.
post #3891 of 5093
I disagree, but to each their own. Audyssey generally sets the sub too low IMO then wants you to use dynamic eq to boost that stuff, when I cut that stuff of.

If you have an 830 (mine) to 900 setting on the gain, a 4-5 db boost is nothing spectacular.

People have been adding a 3-5 db boost to subs for a long time.

Boosting 8 is a jump. You can always call hsu and see what they think. I actually do from -5 to -1 after audyssey.
post #3893 of 5093
Thanks for the advice everyone. If I was to adjust the gain and rerun audessey to get it to +-3 , would turn the gain on sub up or down?

Where did you set the levels of your subs at after running Audyssey?
post #3895 of 5093
This is from the audyssey thread


Some people like to bump the sub trim because they like lots of bass, but that's their preference.
The general recommendation is to listen to music and movies for a week or so without changing the sub channel. Then if you decide you really like more bass, turn it up somewhat. Remember that increasing it by 3dB (from -4 to -1) doubles the amount of power that the subwoofer's amplifier has to provide
post #3896 of 5093
Dr. Hsu or another hsu rep, what's your thought? Have you had amp burnouts?
post #3897 of 5093
Ideally going dual 15hs then you can get more output with less amp draw

My gain is 830, the trim was set by audyssey at -3 last time, and I have it at +1. While I'll agree its mote stress on the amp, the lifespan reduction is debatable. Are we saying instead of 15 years it'll last 13? No one knows. Id rather listen to the sub at a level that works in my room vs what audyssey thinks is right.

I like the audyssey product, and won't dispute what they calculate the power requirements at, but if you read enough of their stuff they think the product is set it and forget it, when its been proven its not. I think it gets most right, but I've never been happy with the sub setting.

Lets not even get into the fact we run audyssey with on eq setting and one q setting, then change it all up after audyssey.

Per the $150 SPL meter they recommend for use with REW, my sub reads 2-3 db lower than the mains. None of it is perfect, and that's why I disagree with assuming boosting trim a few db above what audyssey set it as is a big deal.

But we could go on about this all day smile.gif

I'll just leave it at I've been boosting a few db for 4 years now with two different Hsu subs, and not experienced any issues. I also watch movies very loudly and the sub handles it perfectly. This could be more of an issue running a higher q or in one port sealed or even sealed mode. But with 2 ports open and a lower q, I don't think the sub is stresses that much.

Dr. Hsu can probably shed some light. I also agree its a good idea to listen for a week or with known material before deciding to boost.

Do you mean you change these settings after running Audyssey? That wouldn't be good. You would need to run it again if you changed anything but the gain which we just do in the AVR because it is precise there. Perhaps I misunderstood.

I agree audyssey is not a set it and forget it which all the know it alls in the audyssey thread would agree. It's a good foundation for setting trims but we all like to tweak it. I bump my center about 2db and my sub 3-4db. Also lets no forget the "magic eq" it does on each channel. Setting trims and distance is the least of what it does
