I have recently bought myself a complete stereo system of the following:
Axiom M22Ti speakers (on stands)
Cambridge A500 amp (65 watts peak at 8 ohms)
D500 cd player
T500 tuner
kimber 4tc speaker wire and pjb interconnects

I am happy with the way the system sounds now that it's been broken in and I've played around with speaker placement (although it was pretty good when i just got it). However, I've heard suggestions that speakers should amount to about half of the total system cost. My Axioms cost about as much as my wires and interconnects, and a little more than 1/6 of my total system.

I am considering buying some bigger speakers down the road for my system, because I want more bass. An alternative may be to get a subwoofer (I used to have a Sony SAWM40 sub, but it wasn't a good match for the Axioms). My amp is claimed to be a high-current amp capable of handling 4 ohm loads. Would the M80 be too much speaker for my system? I plan to have them in a roughly 20' by 20' room.
