Martin Logan speakers

Owned 7 pair of  logans over the years plus descent subs and have heard most newer models and honestly they got it right on CLS2Z and the other models well they dont have that magic. Logan also has raised prices as have others and cut corners on quality.

The quality and the amount of bass on the models with passive woofers is very dependent on the room placement and the partnering amplifier. I have my Aerius i in room corners, about 3 feet in from the back wall and about 2 feet from side walls and about 12 feet apart and 12 feet from the listening chair. I do have a subwoofer in the room but I don't find the speaker bass lacking for most music and only use he subwoofer when listening at low volumes. I was driving them with a borrowed pair of Bryston 7B-ST mono blocks for a while and  the bass response from those 8" woofers was completely adequate. Most people have the speakers way into the room so the bass module can't couple with the room. If the room shape allows, they can be placed very close to the side walls without any issues since they don't really have much side-wall reflections. Just my experience.

I have owned Martin Logans for years and family and friends alike are amazed at the sound.  I have a surround system being run by Classe 5200 and an SSP 800.  Movies and music sound great no matter whats playing.
