Two configurations: A 4x10 that can handle 400W, powered to max (400W) A 4x10 that can handle 1400W, powered to max (1400W) Tell me if this is correct. Assuming everything else is equal (porting, tuning, etc.), the 4x10 @ 1400W is only ~5.44dB louder than the 4x10 @ 400W (10*Log(1400/400) or is that the wrong)?? How noticeable is that? I have an Avatar 1x15 and 2x10. I don't like the 1x15 much, so I'm gonna ditch it. Should I just swap it for another Avatar 2x10, or should I ditch them both and shop around for a good used 4x10? This is the reason for my question. Two Avatar 2x10s would handle around 1400W. Most 4x10s I've seen handle less power (I'm looking at Ampegs and SWRs that handle 400W), so that means if I just buy another 4x10 I could downgrade my power amp to something lighter, or just get rid of the rack and get a good head. And then there's the question of how other 4x10s would SOUND (ie tone) compared to the Avatars. So I dunno, answer the poll and give me your thoughts/opinions. It would be cool to break even money-wise (after selling/buying), but I can stand to lose $300-$400.
