The PM2652 6.5" Element Ready speaker features a 1" coated aluminum dome tweeter that is bridge mounted over a mineral filled, polypropylene cone midrange with integrated UV inhibitors. The cone is attached to the Centrex® Plastic injection molded frame by a Thermo-Plastic Elastomer (TPE) surround and moisture, tear and fatigue resistant Aramid fiber spider assembly. This is driven by our matched motor magenetics structure with integrated aluminum heat sinking shorting ring for maximum excursion and output. Additionally, the speaker features fully insulated flex lead wires, corrosion resistant gold plated speaker terminals with integrated expansion connections for our PM2T-S tweeter kit and a fully sealed 12dB/ Octave crossover. The entire system is topped off with an 18 gauge stainless steel and Centrex® plastic grill assembly using stainless steel hardware.
