I have a pair of BG400s and a pair of C4s. The BG400 has 4 five inch speakers and runs 300+ watts to them. With DB this is perfect for any bluegrass or acoustic jam or gig. If I add a C4 it now is 8 speakers and 500 watts. The frequency response if really good for DB.
I have played Senior Center type gigs with the pair along with drums, electric guitar and horns. There was no problem keeping up.
Since I have two sets, I have actually played country gigs with both sets. Thats 16 speakers and 1000 watts. Why do I have two sets? I have problems hauling an upright DB and big bass cabinets. The PJBs are 14” cubes and can be placed around the bass in the SUV so all fits. With this setup I can play 4 or 8 or 12 or 16 speakers and have 300, 500, 600 or 1000 watts available.
(For the record I have a serious Berg setup and an electric 5 string to play with the big boys when needed. )
