James Loudspeaker L4000P 4x10" Passive Sub RARE!

Up for sale is a very rare offering from James Loudspeaker using their unique EMB technology which places an active driver behind an air coupled passive driver which James claims to reduce acoustical distortion and increases headroom. James claims it only weighs 100lb, but I believe it's much more. There are 4 10" active drivers and 4 passive radiators each in their own compartment. The sub is built like a tank and weighs as much as one too. The sound quality is absolutely superb and is well suited for either HT or 2CH music. The sub is passive so it requires an external amp. I am the second owner of this sub, and a grille is not included. There are several nicks on the sub but no major scratches from the previous owner. The faceplate is excellent with no defects on the metal bezel or the drivers. Sub weighs a ton so local pick up only! Can deliver to LA or SD for a small charge. Size 12.125"h X 48"w X 11.625"d Weight 100 lbs lbs Freq Response 18hz - 120hz Impedance 8 ohm Sensitivity 90db Power req. 1000W Subwoofer (4) 10
