I've been using 170 "Classics" for years as my 2-channel music machines. I have them teamed up with a Rocket UFW-10 and the system sounds sweet! If the recording is done well they will let the sound shine through. I sometimes have to check my center speaker to make sure it's off, the 170's disappear with the right material.
They are also the L/R mains for my 5.1 setup for movies and do an excellent job there as well. If the SE's are improved you will be very pleased with them.
