I've got a pair of 2nd hand SWR Triads. I originally powered these using a Soundtech 800W digital power amp (2 x 400W into 4 Ohms) wit a Sansamp PSA-1 as preamp I had to stop using this setup as the sound was indistinct, muddy and the speakers really flapped I've now dug my Bass 350 out of the cupboard but even that doesn't seem to be cutting through. Have other bassists had problem with the volume put out by the Triads? Please help! I'm trying to get away from the endless cycle of buying more kit. I like the sound of the Triads and the sound pretty damn loud in isolation, but can't be heard over a drummer and guitarist.
