LM3-F amp

The LM3-amp is a self-powered low-mid subwoofer cabinet designed to complement AP SK or SK amp touring system. It provides with an efficient solution when there is a need to reinforce the low frequencies within a flown cluster. The LM3-amp cabinet is composed of 2 x 15 inch ND cone drivers mounted in a proprietary horn-loaded band pass system. This particular design reaches a high efficiency on-axis and reduces substantially the sound emitted toward the rear, which prevents from unwanted low frequency feedbacks on-stage. The LM3-amp uses the same cabinet shape and L-track flying hardware as the SK-amp system. The combination of SK and LM3-amp’s cabinets gives a very powerful full range system down to 55Hz.
