Install the SPR-136A 5-1/4" component system's 1" silk dome tweeters in either flush or surface mounts with the convenient quick-snap mounting ring. Then pivot them up to 20° to fine tune your stereo imaging. An aluminum-coated polypropylene cone pounds out tight bass, thanks to an extra-large magnet with a vented pole piece.
External crossovers (12 dB/octave high-pass, 6 dB/octave low-pass) with easy-to-use attenuation controls channel frequencies to the proper drivers for seamless and efficient sound reproduction. Tweeter protection diverts excessive power away from the tweeter.
