Agreed size is a factor here. I'm really looking to go to dual subs, but I'd only be able to bury these in a corner. I'd been looking at the SVS cylinder options for minimum footprint/maximum placement options. The SVS may, and I say "may" until we verify the output numbers, have less output for more money, but they have a serious space savings at only 16.5" round compared to 18x26.
...and on the fence I sit.
