marten Posted July 1, 2019 Share Posted July 1, 2019 Impressive construction is not an overstatement. Well done. Do you have a feel (or a plan) for listening position distance from the speakers ? 1 Link to comment Share on other sites More sharing options...

Do you have a feel (or a plan) for listening position distance from the speakers ? Thank you. There's two aspects to your question. Initially, the listening room will be small.....approx. 2.5m wide speakers to 4.0m to seat. That will change when a new room is built.....3.5m wide x 5.5m to seat. Hard floors, with some soft furnishings. Source is LP, reel to reel and CD, plus downloads. Elson 300B mono blocks, plus Krell amp for bass duties. May add a dedicated amp for the tweeters. Pure silver hand made ribbon speaker wiring. Stainless steel outriggers to be added. Link to comment Share on other sites More sharing options...

Andrew Tilsley Posted July 2, 2019 Author Share Posted July 2, 2019 Here's how a two-way might look (which was the original plan for this design). Having built many horn systems over the past 15 years, I can attest to how nice a two-way can sound...especially if you're using world class beryllium compression drivers as these have. http://www.usspeaker.com/radian 651Bepb-1.htm US$750 each. The beryllium truly gives that "bell like" sound. 1 Link to comment Share on other sites More sharing options...

Andrew Tilsley Posted October 13, 2019 Author Share Posted October 13, 2019 Finally got the AE drivers....plugged in using the snug rubber surrounds. MiniDSP crossed at 750Hz, with 7dB low shelf gain at 40Hz. The bass is tight and deep...very happy. No cabinet resonance. I'll test the horn with MiniDSP also....just to compare with my passive xovers. 4 1 Link to comment Share on other sites More sharing options...
