Excellent mid woofers

By: on 14 September 2016
These are the best speakers I've owned. I'm using two in an MTM by Curt Campbell called the "Slapshots" with a Morel tweeter; they sound great. Accurate but not 'clinical', and they even make poor recordings such as my Hendrix bootlegs sound OK,. There's enough bass output for most recordings to leave the sub woofer off, too. Vocals sound great, really natural and I can listen to these for hours. I keep hearing things I haven't heard before and the RS180Ps really bring out different drum sounds. As a bonus, they look great and I don't want to cover them with grills!
