The triumph of Dynamic Balance

Form follows function in the shape of the LS cabinet. The delicately slanted sides add elegance and style to the appearance while aiding in the breakup of internal standing waves. The cabinet shape also enhances the diffraction control system by narrowing the baffle at the tweeter, creating even greater stability of the stereo image. The structural design of the LS series is reinforced with thick 1" baffles of non-resonant MDF and computer-designed internal bracing systems. These cabinets are rock solid when producing even the deepest bass at high power levels.

The driver cones in the LS series are a polyolefin mineral-based composite like the S series models, but with space-age aramid fibers added for a near perfect stiffness-to-weight ratio. The result is a driver of more musical accuracy. LS models also feature a SL6000 Dynamic Balance 1" trilaminate dome tweeter. Its unique composite dome is produced by a patented vapor deposition process that adds a thin layer of aluminum and stainless steel to the polyamide base. Like the most sophisticated metal dome, it provides greater frequency extension and detail, but with the smooth non-resonant character of soft domes. Finally, as a crowning touch, each LS model is equipped with gold five-way binding posts as connectors, providing long lasting non-oxidizing electrical contact with your amplifier and assuring top performance - now and in the future.

The LS50 combines two new MW7100 Dynamic Balance 6.5" drivers and the SL6000 Dynamic Balance 1" trilaminate dome tweeter in a vented design. This remarkably well-designed and executed loudspeaker is the most compact of the LS Series and a very big performer in every sense of the word. Its extended range and large scale stereo presentation belie its size.
