first of all I like Ascend a lot when music is of major significance. If HT is #1 priority, I might look for towers that can handle better midbass and dynamics. If there is any weakness, at all, of the Home Theater compared to a good cinema, its usually in the midbass. As far as video, discrete surrounds, LFE, etc, I think the HT is better.
There are workarounds, but involved. I can't choose for you, because I don't know. Note that small increases in dimension look bigger in real in regards to large subs. The pb12 seems to be huge, but I like what I read especially since the very recent amp tweak. Outlaw is perhaps the most thoroughly respected brand that I might know of, particularly for their electronics.

I will be taking your recomendation on the ascend acoustics 340 fronts and center, pair of 170 rears, & Onkyo 805. What is your opinion of the outlaw LFM-1 sub vs SVS PB12?
