I have a Laney R115 (15" speaker) and it suits me quite well, im not overly pleased with the sound, but its fine. Im using it with the R5 (300W 2x10) The music store has the R410 (same cab, just 4x10") for a bargain basement price and I was wondering if I should upgrade. I couldnt use both cabs, but id be ok with selling the 115. Would it sound 'better' (IYO)? Would it be louder? Any other advantages? Ive played the can with the head version of my combo and it sounds better to me. . . .
