TL upgrade for AB700/800?

Does anybody know what moves I need to make on the crossover to accomplish this? I know I could drop in the RDO-194's, but would like to run the same tweeters that I have in the 1.2TLs.

Saying that it's "too hard" to pursue your dreams is no different than admitting to yourself that you are too lazy to achieve them.

    These are among the first generation of high-end Polk in-wall speakers. They run the same drivers as the SDA-SRS. In this case they use the SL2000 tweets and MW6512 driver.

    The 700 has one driver/tweeter and the 800 has two drivers and a single tweeter.

    John, The RTA-8T has an almost identical Hi-Pass section. There's an RTA8TL-Rev2 Schematic, for use with the RDO-198s. Looks doable, if you can fit everything on the circuit board.
