Probably I'm overkilling, but I'm using a tri-amped rig. Playing a bass guitar for over 30 years, I've learned that: 1-You need a lot of power to make a lead gitarist humble and to have expression, transparency and a constant sound at low and high volumes. 2- I use a Powersoft amp (M28q) delivering up to 2800 Watts: 1400Watts to an 18"sub, 700 to a 2x12" and (limited) 700 to a 2 x 10" ( Beyma 10mcf400Nd). More technical: A low B is about 33Hz, for this you need a real woofer (at least 15""). Signal analysis shows that subs have ups and downs of many dB's in their frequency range. With the dsp in the Powersoft you can create a fairly flat frequency response, (dependant on the size of the room) which has a great impact on transparancy. A standard speaker grille can not handle this, hence I use a Weber barbecue grille for the woofer. Also overtones of bass strings can reach up to 12,000Hz as shown by signal analysis, which explains the expensive Beyma's. Another technical point is that passive cross-over filters lower the damping factor of amp-to-speaker interaction and may add some mud to the sound. In my studio, the bass guitar players using the rig are satisfied. It was expensive (speakers ±1200$ and cabinet materials ±400$, Powersoft 2,000$), but we are happy with the rig. In conclusion, I wanted a rig that is able to reflect my playing. My dogma is that you can not add something to a rig that is not capable to pass it, but filter these things you don't want.
