Where will we be in five years. To me things seem to be changing SVS and Adire and DIYers and making great bass, for resonable cost. Will the mainstream manufacturers follow? Some subs out there are great like the Paradigm servo15 and the big Velo's etc. But these don't have the bang for the buck of DIY. Are we raising the bar or are we such a small group that we will have no affect on the speaker comapanies like B&W, Energy, Paradigm, Totem, Polk, and a million others? I think for sure we will see smaller digital amps with tonnes of power and no fans for reasonable money fairly soon. I personally will never buy another piece of gear with a fan! What do you see in the future for commercial and DIY subs? Bass doesn't go much lower, and crazy volume levels are here now if you want them, what's next?
