I'm getting a new PartsExpress 250W plate amp to drive my Tempest Sonotube sub (my Peavey is just too noisy!), and am considering buying two of them to biamp. Has anyone tried this? My concern is that the Tempest will no longer be able to fill my room and make my heart rumble with the lower power of the PE250 as compared to my old Peavey CS400 bridged. Any thoughts? Also looking at making a easy enclosure for the PE amp, since there is nowhere on my Sonotube to mount it. If anyone has experience with that, I would welcome the input... Thanks!
