My limited experience with the RL-P 18 is that it is a very low distortion driver by most standards (5400 LMS is king ). This in comparison to a Mach5 IXL 18.2.2. The RL-P was cleaner at all levels, until in convieniently destroyed itself. Other than that, it is not a driver that is going to take well to extreme abuse. If the coil is bottomed, you're SOL. As everyone is saying, this probably isn't your best bet as he's not after pure SQ. One thing this driver has on it's side is looks. Not much comes close to the aluminum cone and rubber surround. Oh, and it performs well too. A key piece of advice is the mention of having your goals and your equipment matching. If you wanted a nice looking woofer with high SQ then the RL-P would be a good choice. If you're looking for SPL then a BL would be a good choice.
