I posted about this recently - yanking the tweeter from an older Avatar 1x12 cabinet with a Delta 12LF driver, and installing an Eminence LA6-CBMR 6-1/2" sealed back midrange speaker and an Eminence PXB:1K6 high pass board. http://www.talkbass.com/forum/f15/need-help-wiring-replacement-high-pass-filter-avatar-cabinet-mod-924361/index2.html This is an idea that's been kicking around TB for years. It was an easy mod (once I got good advice here on wiring up the board). I've been gigging and rehearsing with this baby, and it's a champ. My amplifiers' tone controls work in a way that's new to me - real tone-shaping in the upper midrange. It's very flexible in bringing out good tones with different basses. (It does what I always expected a tweeter to do but they never did.) It weighs 50 lbs. I am just digging the tone options. If you can find one of these older (non-neo) Avatar cabs for a good price, go for it and do the mod.
