There is a VTF3 mk4 in the Hsu B-stock section for 607, or $706 shipped. That isn't much more costly than a VTF2 on sale and it is a beastly subwoofer.

That is nice, but I'd really rather have the down firing model though.

When I got into this hobby everyone told me to run my satelites at 80 and cross my sub at 120. This was a rule of thumb I followed for a long time but was never completely satisfied as my sub was very localized during more mid-bass action in movies and music. Now I keep everything at 80hz and notice a bigger difference. Hell, id cross my sat's lower if they could perform in the 40s and 50s with decent respect! I have the HSU HB-1's and they are very capable of giving a decent mid-bass punch of 80hz and I don't feel the need to fill the missing gap, I would suspect your Klispch speakers are probably the same? I could see the 80/120 rule being applied in speakers which are less than capable of giving a decent mid-bass presentation, or massive roll-off occurs right at or just before 80hz. However you Kilipsch speakers should be more than capable of playing down to 80hz at a respectable (just not as loud as the sub). Just curious if the localization of 120hz really bothers you or have you tried crossing at 80hz?

Not sure what you mean.

I do not cross my sub at 80, my speakers are all set to 80 and small, which means they play everything down to 80hz, and the rest is directed to the sub + the LFE content (keeps sub from being localized). The LFE channel is completely different. It can have content up to 120hz that is meant for the sub only, and should, so the rule is to keep your LFE channel at 120hz so you arent clipping anything meant for the sub.

If you set the LFE channel at 80hz, anything above that meant for the sub goes, well, no where. It is lost IIRC. Granted, this is a small issue in content, but the speaker crossover and LFE crossover are two different things and functions.

Now setting your fronts to something higher than 80 when they can play that low is definitely a bad move, because you are sending content to the sub that it does not need and it can be very localized. I used to have small fronts that had to be set at 100hz, it was kinda annoying.

I never know where my subs are, but I sure know they are doing something.

That's new to me, thanks for clarifying. I always understood the crossover as frequency across all 6 channels in a 5.1 setup (at least this is how it was explained to me). Perhaps I am missing out on keeping my sub at 80hz but I just notice the sub being much more localized and slightly boomy when crossed at 120hz. However if a movie's LFE track is designed to play as high as 120hz then perhaps I'll cross differently in the future.

Thanks for the information

The LPF (low pass filter) for LFE (.1) is not a crossover. It is a low-pass filter that is usually recommended to be set at its highest level, which is probably 120Hz.

Boomy sub is due to placement or improper calibration.

It's not calibrated incorrectly but it's also not in the best spot either... Due the shape of my room and limited areas for placement of this massive sub there are only two spots for it and it comes down to (for me) which is the better of the two. After mucking with with it at 120hz last night it's too boomy and very localized in it's location. I may be clipping that channel, per what I have learned here, but I am going to keep at 80hz for the time being.

Hi there,

Not sure if this was mentioned already, but if you feel it's too boomy in that region, you can try setting the crossover to in on the subwoofer and the crossover knob to max. Set the LFE channel crossover back to 120 Hz. It may not make much of a difference, but it's worth giving a shot. Ultimately, it's whatever sounds best to you. Using the dBSPL meter with the test cd, would help in determining why it sounds boomy to you.

Sincerely,
Kevin

You can also set the sub xo to 80 Hz. Only about 5% of the LFE will be cut out. You most likely will not notice it.

In my room we had to set the VTF15's to xover IN and 90hz (max) to fix an issue and get audyssey to create a flat response. I surely do not notice anything lacking

Help.
I was watching some movies this weekend and I notice during some kick drums on the sound track I will hear a faint popping noise. First I thought it came from the one of my hsu speakers. I checked the subwoofer cone and there is a small crack just below the surround. What the heck. I'm one of those people who tries to take care of their speakers. The subwoofer is Only a year old never pushed to its limit just recently happen. How much is it to replace a woofer cone?.

It won't cost you anything. Just let Hsu know, because you are covered under warranty.

Could just be a hidden defect that didn't manifest itself until now. I wouldn't worry about it, Hsu will take care of you. I have had two VTF3s for years now, never a problem. One of them is over 5 years old and the other over 7 years old, both still works like a charm, despite my continuous abuse.

There's no difference. Low frequencies behave in such a way that it doesn't matter. That doesn't mean to say that you haven't heard front firings that sounded bad, or only bottom firings have sounded good but trust me, it was only by chance that the down firings have sounded better. If that's the case at all.


Too many great sub designers make front firing for there be a definitive advantage with down firing. HSU, SVS, JL Audio. HSU even does both, and for their flagship model it's front firing.


Again, it doesn't matter.

+1 it's like when I was in high school and tried weed a few times and it didn't work. Just so happened that the first time I smoked a joint it affected me. Thought that was how I had to do it to work... until I found out that wasn't the case. Just coincidence. Ahh high school

Maybe you guys are right. Heck, you probably are. I just always figured that a downsizing sub had an advantage of working with the floor or the room more directly. I guess this is incorrect?

Yeah, it doesn't work with the room like that. The only potential advantage that down-firing might have is, since the woofer is facing away from the listener, some higher order harmonic distortion may get masked. Outside of that, I can think of no advantage of down-firing from the perspective of sound quality.
