Is it true that 10s are the best for tight, punchy bass; and 15s are best at producing deep, solid walls of bass? Or can you really have tight, punchy, deep, solid bass with all 10s or all 15s? I currently use a 200 watt Eden Nemesis 2x10 and a 160 watt Carvin 1x15, depending on where I'm playing. No offense to Carvin owners, but the Nemesis is a superior combo in terms of sound quality. However, I've noticed that the Carvin's 15 inch driver can take more of a pounding from my B string without sounding like it's breaking up at high volume. Suppose I wanted to put together a larger bass rig. Could a good 4x10 cabinet produce solid bass and handle a B string well at high volumes, or would I be better off with a 2x15? I don't want to quantify everything like comparing the cone surface area of four 10s versus two 15s or anything like that, because numbers don't always tell the whole story. I'm just wondering if there really is a significant difference in the ability of 10s and 15s to produce all the qualities in bass that we want. Maybe enough 10s can sound very deep and solid. Maybe high quality 15s can sound tight and punchy. What's your experience with 10s and 15s?
