I sell them at work, and have been very impressed. Good tweeter, decent mid, big magnet, and seem to handle some serious abuse. IMO, they blow away a memphis pr, and put up a tough fight against a JL tr.
I sell the full line of RE audio coax's, and never had any problems. They have a very clean and balanced output. I also carry alpine type R, PG rsd, and mb quart and they go step for step with all of them.
