I am looking for 34 - 4" bose speakers to put in custom column cabinets. I have 18 already from a pair. I want to combine my 18 with 34 more to give 2 systems of 26 each, wired in series giving 208 ohms impedance each for special amps I am now building. See my thread at tube/valve under "medium power circlotron amplifier" for details. The speakers must be older style, with 4 mounting tabs, not 3 as the newer ones are three tabs are only one ohm. I don't want the cabinets. midmoe
