Sounds like a driver problem to me, I don't want to jinx myself but I drove my 3.6 with 200 watt classe power for years and it could get congested when cranked on dynamic music. Macintosh 501 mono's made this a different speaker!
However, unless you play really loud more frequently than not...I mean party loud you should have enough power with your lamms IMO.
