I'm singing the 4x12 blues recently: it's got a cold, cold tone. Too much beamy highs, too much rumbly bass, and not enough air and mids. And coupled with a Fender, you KNOW I mean too much bass. So I'm looking to trim this baby down and get some more air and midrange. My two options right now are as such: A 4x10 cab (Marshall? Avatar?), possibly with the bottom two speakers pulled (aka "detuned"). This should break up the closed-back standing waves problem and give a little bit more open-back feel, with the tightness of closed. A 2x12 ported cab (Freda). These are closed back, but ported so that the air gets pushed out, removing standing waves and doomphiness. So here's what I'm worried about. I'm trying to sweeten highs and reduce bass grumble. Just a tad. Freda brags about how deep and resonant sounding his 212s are, and I wonder if it won't be more of the same problem. I've been searching for 12" speakers that emphasize the mids over the bass and treble, but I can't seem to find any. 10s, on the other hand, seem to do this naturally. But I'm not looking to completely overhaul my tone: I don't want to wind up with a vowel-shaped, barky EQ. I really wish there was some way I could try these out before buying. Any opinions would help.
