These are Amazing open baffle DIY speakers I built from solid cherry and cherry veneer. The main drivers are Supravox 215 EXC 8” field coil. Very good condition. The woofers are 15” Hawthorne “Augie” for open baffle. They are powered with Keiga plate amps. The power supply is included for the Field coil drivers. They also have Fountek ribbon supertweeters. The field coil drivers run full range and go down to about 50 Hz. The subs go down to at least 30 Hz. Excellent sound with some of the best imaging and vocals you will ever hear. Very efficient and I was powering them with great results using Welborne Terraplane 300B monoblocks. The field coil drivers alone are worth my asking price. Non smoking, climate controlled, and pet free environment. Local pickup only or I can drive up to 100 miles to meet 1/2 way or deliver. Please add 3% for Paypal fees.
