Spock:
No sub with the M80s -- they are used strictly for 2 channel music in a smallish listening area, and I listen primarily to classical (that means I'm not a bass freak). The bass from the M80s are sufficient for pipeorgan or percussions from very large orchestral pieces.
I used a Deftech sub when I tried out the M22s. I believe I might have posted a review here somewhere. I don't know if "weak or thin" are the proper words to use, but the sound is definitely not "real". It feels like I'm listening to my MD player (inferior sound compared to CDs) through some cheap headphones ...
Maybe the M80s are THAT good!
