Hi, My current bass rig is an older mesa boogie diesel 1x15 paired up with an swr triad (1x15, 1x10, 1x5). I'm running the rig with a sansamp RBI, behringer composer pro xl compressor, and a stereo 2x600 poweramp. Together, this rig is badass , but out of curiousity, does anyone know the db SPL of the older mesa boogie diesel 1x15's? The triad is only 98db and sounds awesome, but the mesa sounds much louder. In a rock setup, this rig is awesome because the triad brings out the blended overdrive from the RBI nicely and the mesa adds booty. Any info is appreciated.. Thanks!
