Up for sale is my Martin Logan ML1500X 15" powered sub.It is excellent cosmetic condition with only a minor imperfection on one of the machine screw holes.A small paint chip from the finish came off from moving it around but I glued it back on and it's fine now.You will never see it because either the feet are on or the grille is in place.Other than that no real blemishes on all sides plus the driver and amp.The grille is in excellent shape as well.Condition is an 8-9 depending on how picky you are.The sub functions perfectly and is a powerful performer in all regards.It is very accurate and precise for music but has thunderous output for movies.It's also very compact for a 15" unit so fits nicely in many decors.PBK is also available for room correction purposes.I have the box,all packing material,manual and power cord.The sub is packed from the factory very well so no issues with ground service.
