I had this thought on the car ride home from a work trip yesterday. Granted my brain was fried after two days of meetings but I was wondering if I removed the upper speaker from my vertical sealed 2x12, if I would essentially have a detuned 1x12 cabinet. Before I go through the trouble of opening up the cabinet, unsolder wires, remove the speaker and reconfigure/resolder wires, would this just sound complete crap or would I be getting the detuned cab benefits. This idea would solve my impedance mismatch problems I'm having as now the cabinet would be 8 ohms and also my power efficiency problem as now this would a 100W cab instead of a 200W cab. But I'm not sure of the tonal outcome.
