Say On, O' Swami of Sound!
Wow. The big enchilada with all the chiclets!
And what, pray tell, O' Swami of the Site, side firing towers are you listening to these days?
Frankly, the side firing option just seemed optimal for me- I was hurting for space on my HT main wall, and these saved me that two feet of space that a couple of subs take up. Plus, it makes sense to have two subs equidistant, rather than one sub off center somewhere.
