Biamping Dunlavy SC-V

I experimented with angled panels sitting atop my SC4's several years ago. The panels that I made could be angled backwards at varied setting,15 degree tilt at the top seemed best in my room..The bass was not only better but the upper midrange also became more focused..These same panels also worked with various Thiel models as well, same sort of results with more focus..My panels were made of heavy fiber board and covered with black trunk mat..lightweight and easy to remove..Having 4 identical amps..the bias may not be the same...so there could be some variation between all 4..3db is a whole lot of variation between 4 amps that are the same..Same cables on all 4, same IC's, speaker cables, and power cords, some hooked to different ac outlets or powerconditioners?..Tom

The pairs of Dunlavy drivers are 8ohm wired in parallel except of course the tweeter which is a single 4ohm driver. When I biamped my SC4s I thought the mids and highs stuck out more than the bass. I never used an RTA to measure this perception. Sean is correct about the crossover freq..of 200 hz. it uses a 8.2mh inductor to roll the highs out of the woofer and a 200 mic cap to roll the lows out of the mids. Could there be a dropping resistor in the mid crossover that some how gets bypassed when bi-amped?..That would be wierd..Tom

You can unscrew the rear terminal panel and the entire crossover will slide out a tract..In this way you could diagram and inspect the crossover..These babies are ripe for component crossover upgrades..What a suprise lurking..Tom
