Hi, SA-XR users, I'm seeking some advice from anyone who knows the circuitry of either a XR57 or XR70 that could help me with a crossover idea. When in Biamp mode, would it possible to set up a 1st order high pass filter for the digital tweeter amp so as to bypass the need for even a capacitor on the speaker leads? I'd like to start with a high pass frequency of around 1.3kHz, first order slope for my tweeters(Stage Accompany SA8535's). It would also lighten the load for the tweeter amp not needing to run full range. Even the best capacitors in the world add coloration. Worth a try, I'd think. Thanks and I'm looking forward to any advice.

Hi, Folks, Moray, this might be in your wheel-house. I have a pair of KLF30's and have always been facinated with K-tubes and perhaps replacing the mid & high horns...three-way to two-way system conversion. It just so happens that I have a pair of Gauss 4080, 4" drivers lying around. Here's some questions; Besides being interested in trying The Gauss's with some version of K-tubes on the two inch openings, have you ever heard of anyone trying 4" K-tubes utilizing the rear wave projection of the four-inch diaphram? Any suggestions? Peace, Speak-up
