Has anyone ever bottomed out a Tempest with a 250w amp? When I model my design with lspCAD excursion is only about 25mm p-p with 125W into 8ohms (250w in 4ohms). However, I beleive that most amps can put out much more in short bursts. A paradigm PW2200 is rated at 250w and 750w dynamic power. Whenever you look at car amps they specify the RMS power and max power. I have a shiva(100l, 4" port 21hz, sonotube) hooked up to the same amp and I bottom it out quite often. The amp is only about 1/3. Should I be expecting much higher volume levels before I bottom out (or the amp shuts off)?
