You may want to the try the M3ti. The M3ti is one of Axiom's more laid back speaker, owing to the 6.5" driver. You'll probably consider them richer sounding than the M2ti. I have a pair of the M3ti's with a Acoustic Research Sub (with the same stats as your, it is the ARS108PSB) and I think it sounds very good. Also, your speakers may just need time to break in. Hope this helps!
