I think that I've asked this before, but as an exercise I wonder what people think would be the characteristics of an ideal support speaker. Rythmik FM8 looks good because it can play clean at higher frequencies and also dig deep. 4 x L12 would be more affordable. If you were tasked with building an ART system from scratch, what would be your strategy for the support speakers and why? I'd be interested in what people think about a 2 sub, 4 sub, or even a larger system with surrounds that play deep. What would work well and is also a good value?
