...and my 210 is just not doing it for me. It's just doesn't go deep enough before farting out, and its too clear and precise in the mid range (I'm going to go ahead and say to much Jaco, not enough grind). I've been thinking of all my favorite bass tones, and I'm starting to realize that most of these guys use bigger speakers other than 10's. A good portion of them do use 810's, but I can't afford something like that, and I really don't need one quite yet. But I was thinking that a 212 or even a 215 might suffice my quest for tone. Some examples btw: Yes I do realize that most of these guys are running cranked tube amps and Al is even running a distortion pedal. I can't afford a tube amp right now, but I can get a VT bass. Next on my list is a tube amp, but until then my GK 700RB-II is doing me just fine. Except for the fact that I am sending all 480 watts at a 500 watt 210, and it's not getting the lows I want, or the grind I want without farting out. It's an Avatar 210 btw. I have tried both a Mesa Boogie 215 and a Berg 215 and both of them sounded super fantastic, including at near ear splitting volume. I was testing them with an SVT and a Mesa M9. The lows were definitely there, and the with a little eq'ing and pushing the amp hard, I got a bit of the grind I'm looking for. I have not tried a 212 yet, but I'm thinking it may not be a bad idea to look into. So now here's the kicker. I want to build this cab. My roommate has been building his own cabs for 5-6 years now, and he told me that if I buy the speakers and the hardware, he could definitely build one for me. I told him I would help. Of all the available plans out there, which do you guys recommend for a 212 or 215? Also, sealed or ported? Which will be defined, but incredibly present in the low end? Also, speaker recommendations? Celestion? Eminence? Peavey? Any others? Best place to buy?
