Install the SPR-176A 6-3/4" 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 poly cone pounds out tight bass, thanks to an extra-large magnet with a vented pole piece.

External (12 dB/octave high-pass, 6 dB/octave low-pass) crossovers 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.

Extra Large Rubber Surrounds: The extra large rubber surrounds enable low frequency bass reproduction and maximum cone excursion.

Cast Aluminum Frames: Each woofer is mounted to a custom cast aluminum frame for added strength and maximum bass reproduction.


1" Silk Dome Tweeters: The 1" silk dome tweeters offer clean, non-fatiguing sound even under extreme high frequency demands. 

Standard Tweeter Mounting Options: The tweeters may be flush or surface mounted. Once mounted, the tweeters are adjustable and may be swiveled 20 degrees for optimum imaging.
