Jamming through the band's practice amp is easy, as I just bring my bass, but I don't like it. The practice amp is a Fender Rumble 100. Sounds good till I have to turn up to hear over the loud drummer, then it loses the highs and the lows are muddy. I want to bring one of my 15" cabs and the Markbass LMII head I just got. I thought I'd make it easier by making the cabs maybe 20 pounds lighter, so I want to change out the EVM speaker for a neo. Either a Basslite 300watt, or Kappalite 450watt, but am undecided which one. I thought it best to do both my cabs with 8ohm, and may also use them with my SVT. Also thought about just doing one only with a 4ohm. My cabs are vented and are approx 3.3 cubic feet. Both speaker types will go as low as 1.8 cubic feet, with the basslite to 4.2, and the kappalite to 5.1, so my cabs are right in the middle. Any advice on which speaker type?
