Dear @whart : Normally planar speakers are not high sensitivity and are far away from your horns.
Marbe you can make some research to find out if a planar small speaker can works for you and the Lamm amplifiers working as satellite speakers with your subs handling frequencies from 90hz-100hz and lower. In this way the Lammas will " see " frequencies over 100hz and with out the low bass range you could have headroom to handle the planar speakers.
Other alternative could be the Kerr K300 speakers that comes with a planar tweeter crossing at 1.95khz that means it handle a wide frequency range and along that the K300 is a transmision line design that's has really low distortions neare the performance of planar speakers. So that you can get that immediacy and take advantage too of those subs that will handled the frequency below 80-90hz, sensitivity of the K300 is 89db.
Btw, your Avantgarde are very fine speakers, the distributor here ( not any more. ) was a friend of mine and I had several sessions with because not only in his demo rooms but at his home he has those Avantgarde in his system. very nice.
