I just got through reading all five pages of Storm's enquiry about powering the 250s. I'm running Altec Valencia 846As in a DIY active configuration via a Behringer CX3400 active crossover. The treble poweramp is a Yamaha B-2 v-fet (100W per channel). The bass amp is a Kenwood Basic M2(225W per channel) I'm no wiz with the technicalities of the amp/speaker interface,but from what I've read it seems to me that the removal of the passive crossover between the amps and the drivers gives the amplifier power an easier ride. The Storm/amp power thread has given me pause to ask the same question; Do I have a safe enough power-margin that I can generally put aside having issues with clipping? I like my music loud(around 95-100 dB),but not really much louder.The room is around 24ft x 40ft. Thanks in advance to any respondents.
