Alpine Type-X REF Components
Alpine designed their Type-X REF Series component speakers to reproduce your music with the same accuracy and fidelity as speakers used in recording studios. You'll hear your music exactly as it was recorded nothing more, nothing less.
The SPX-17REF component speaker system uses precision 6-3/4" woofers with sturdy cross-ribbed aluminum cones to deliver the bass, drums, and vocals with an impressive kick. Tough, synthetic rubber surrounds keep the cones under tight control, and the strong cast aluminum frames ensure uncolored sound and long-term reliability. Alpine includes plates that allow you to mount these woofers in oval 5"x7" and 6"x8" speaker openings.
Ring dome tweeters
The 1" ring dome tweeters broadcast delicate high notes and overtones with extreme accuracy, bringing your music to life without a hint of shrillness. Alpine includes a mounting bridge that allows you to mount the tweeter directly to the woofer, so you won't have to cut any holes if your car has no factory tweeter locations.
Crossovers control and protect
The external 2-way crossovers feature 4-level tweeter control, so you can dial in the right sound for your vehicle. Biamp connections allow you to amplify your tweeters and woofers separately, and tweeter protection circuitry guards against damage from overpowering.
