HSU VTF-15H and Infinity SW-12, use both or just VTF-15h?

[phampau]

I have been doing research for the past couple of months and decided on the HSU Vtf-15H for my sub upgrade. I am also expecting my Denon X4000 to be here this week and need some advice. I'm debating about whether I should run the Infinity SW-12 with the Vtf-15h or would it not do me any benefit at all? I did the crawl today to find the best spots for my sub and have found 2 spots where I think I could put each sub so long as they would be "compatiable". The Vtf-15h would be behind my MLP and the SW-12 would be in the front right of my MLP by the fireplace. The sw12 would be wired and the VTF-15h would be wireless if that matters. From my reading, the denon x4000 has sub-eq which would eq both subs separately so i'm thinking maybe it would be better to run both instead of just the Vtf-15h. From reading the forums, i have read mixed reviews, some say never to mismatch a "better" sub with a "lower" sub and some say it sounded better and fuller? What are your thoughts? Thanks for your help in advance! Paul

I say try 'em and see what happens. They could cancel each other out in some frequencies and leave you wondering where your bass went; or SubEQ could work some magic and make them compliment each other. Since it won't cost you anything to try, you might as well play mad scientist. If you don't, you'll always wonder what would've happened if you had. If it doesn't work out, it's not a decision you have to be stuck with, after all.

They won't cancel each other out. Does the sub EQ allow for 2 subs? If not, the SW12 will struggle to keep up with the 15H and commit Hari-Kari. When going multi-sub it is recommended that they be identical so they have the same in room response. Two subs with vastly different response will not always result in better sound (and in this case, this is what I would expect with these two), but you never know until you try. If the 4000 supports EQ for both, then I'd definitely try it.

X4000 does indeed support Dual SubEQ. See this FAQ for some additional details:

tldr: SubEQ should be able to compensate overal response from two different subs

 

[ReUpRo]

Audyssey SubEQ calculates distance and phase of two subs independently. (This will also factor in differences in signal cable length, distance to sub and in your case, one being wired and the other wireless.) At the end of this, both subs will be time aligned to the main speakers and phase aligned to each other.

Audyssey will then apply a single filter to the combined room response of the two subs. This happens to be the recommended approach to integrating multiple subs.

x4000 will be in tomorrow! I will play around with it this weekend and report back with my findings! Thanks! Paul
