I didn't cross my line sourced RTR's to the 1D's but augmented them. I run the 1d's full range bi-amped. the id tweeters are used from 1K up since the recommended audio reasearch x-over is used before the tweeter amp. I'm trying to figure out if R2,L2 and C1 are the x-over components in the schematic (of the rtr 6-15's) and if so Which can I change to up the x-over point from 1200 to about 3000 Hz? The esr 6's crossed at 1.5K the esr 15's at 1.2K. I y'd out of the audio research x-over and go to a st 70 to run Just the rtr15's and to a mosfet 120 (60+60) to drive the maggie tweeters.
I also run a Janis W2 subwoofer w/it's supplied crossover amp combo. I use the Janis and the rtr's very sparingly mainly to kind of fill in the freq range. A bit more "air and gut punch". i don't turn up the volume (high voltage) past the "0" midpoint mark on the rtr's. never an arc or strain especially using the modified st-70 tubed amp.
I settled on placing the maggie tweeters on the inside and the rtr's on the outside of the maggies. The "air" is spread and not beamed at you and the maggie tweeters handle the center field. As always the 1d's need a lot of placement experimentation to get the tweeter field and the whole speaker sounding right to the individual listener.
