I replaced the stock speakers in my Carvin RC210 with Eminence Kappas, and while the sound is now relatively massive, the thing has become heavy. Real Heavy. Like it negates that value of being a combo in the first place. My new theory is that I'd like to A) Get new lightweight 10" drivers for the carvin cab B) Get a lightweight 12" cabinet (like a Flite with horn) or lightweight 2x10 or 15" ampeg portabass cab. Anybody know of drivers for (a)? Anyone got any advice on B? I figure, from reading about portabass, that I would want a little more beef as opposed to with the Flite it seems that the downward firing 12" will provide more oomph. This is for DB and Electric, everything from faux Jazz to Rock. Any feedback would be appreciated, no pun intended.
