I’m planning to build a pair of high efficiency full range speakers. Fostex fe206en or maybe some coax of a bigger diameter. I could also build enclosures to fit the electro voice 12trxb triaxials I have laying around. 12" full rangers would be nice. Horns too. Not shure yet. I’d also like to test my cerwin vega AT-15 on a smaller tube amp. They are rated to 102db, but they have a reputation for being a difficult load to drive. I also have two pairs of infinity that have a rather low sensitivity (rs1000 and rs4000)
