I have a pair of the older 80wpc 16s. Happily content, except when I think 4 80wpc amps isn't enough. I haven't bridged the 2 75wpc Crown D 150s either, (would also need 3 more)but there would be only a very silght if at all difference. Now. I have also a knocked about Altec 9440, but alas of only one. I would need 4 or 3 more running in the 800wpc bridged mode to perhaps gain anything substantial when one thinks of "more power" by the usual rule of thumb.
