to start i, i've got the model with the avatar proprietary deltalite ii 2512 drivers. some folks love the sound, i find myself wanting to bridge the gap that is present from the upper mid dip in these drivers to where the horn picks up. i plan on deleting the horn, as i do not favor them in a bass cab (i play a kappalite loaded mesa powerhouse 215 and an svt 810). if my research shows correct, 1.6khz seems to be the common crossover point for this set up, but with factory 2512 drivers. i can't find any t/s parameters on the avatars save for statements by others about the upper mid dip. should i cross over higher to let the woofers do their thing until they run out of freqs? if i cross over at 1.6khz, will the upper mids produced by the 6" drivers be loud enough so that the lows coming from the drivers won't overpower them? next... i cant find a 4 ohm crossover for this application. should i run two input plates each with an 8 ohm 1.6khz (if that's what we go with) on them? last question... does anyone make (or can anyone here make me) a cab ready one to these specs? thanks, folks!

The reason for using a mid driver isn't frequency response so much as dispersion. Twelves can go to 3k hz or more, but they'll be beaming. 1.5 to 2k hz is a good range to go from twelves to a midrange, but as for the crossover that's probably a DIY proposition.

This crossover would work for 1600hz . It's a highpass so it won't change the ohms of the cabinet as it only affects the mid driver . You will have to take the existing crossover completely out of the cabinet and run the power from the speakons directly to the woofers and the crossover also . Then out of the crossover high output to the mid driver .

Could you run two six-inch mids with this?

The guys at avatar seem to suggest 2.5-3.5khz.

That's probably because they use 2.5 khz in their 12/6. But they also use 12dB filters, which is marginal. The only reason to use either a 2.5 khz crossover or 12dB filters is to keep the price down.
I've considered replacing these drivers with a set of 3012 HOs

If you're going to that you might as well start from scratch and do it right with a greenboy or BFM design.

IMHO with those woofers it is a waste of time and money. Your speakers go up past 4.5k.

Not so sure. The Avatar OEM deltalite ii drivers are a FAR cry from an eminence factory model. The upper mid dip is so severe, it almost seems like it doesn't recover. It's well documented that many users feel the gap between these drivers and the horn is too extreme. Others love the combo.
