If I ever get around to tri-amping my front three, it would be via a 770 with the addition of a 7100/7125. The 770 would drive the woofers of the front three plus full-range to the surrounds. Three channels of the 7100/7125 would drive the mid-range of the front three and the another three channels would drive the three front tweeters. If I became nervous about startup or shutdown currents damaging the tweeter, I would place relays or other protection between the tweeters and the amp.

The idea is that a well-constructed active crossover ahead of the amplification that would allow the elimination of the passive crossover between the amp and driver(s) would eliminate more signal degredation and driver control issues than it would create.

Of course all this would require some analysis of what my current passive crossovers were designed to do and to replicate those functions in one way or another in an active crossover prior to the amp channels for the front three – a time consuming task, hence, I don’t know when I’ll get to doing this.
