About the Alpine SPX-17REF
Alpine Type-X REF Components
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.

Cast Aluminum Frame: The woofers feature a cast aluminum frame. The frame is lightweight, yet rigid, to resist flexing during long cone excursions to deliver powerful bass. The frame contains a heat transfer motor/frame coupling to keep the voice coil cool. The tinsel leads are woven directly into the spider for ultimate durability.
Cone Construction: The woofer uses a cross-rib aluminum cone. The ribs both strengthen the cone and help break-up major resonant modes. A convex aluminum dust cap further reinforces the cone while keeping mass low.
Surrounds: The speakers use patent-pending NBR (Natural Butyl Rubber) surrounds. This design and material lets the woofer motor structure maintain stable suspension integrity at any drive level. The natural butyl rubber surround also features Edge Reflection Control to further prevent resonant modes within the suspension system.
Motor Structure: The SPX-17REF's woofers neodymium magnets allow a shallow mounting depth and a narrower motor structure, for easier installation.
Mounting Options: The woofers fit standard 6-3/4" applications, and also include 5x7/6x8 adapter plates and multi-hole 6-3/4" adapter rings to fit a wide range of vehicles.
Construction: The tweeters use ring dome technology; which moves the voice coil closer to the center of the moving mass for added stability, control, and dynamic response. The triple stack neodymium magnet structure offers high efficiency and low distortion. The back of the tweeter has a non-reflective cast aluminum tuned air chamber to increase SPL and dynamic response. A special tweeter bridge adaptor allows you to convert the woofer and tweeter into a coaxial speaker.
|Mounting Option||Mounting Depth||Mounting Height||Cutout Diameter||Frame Diameter|
|Coax Mount||2.350" (top mount)||1.248"||5.278"||6.03"|
Construction: The crossover network has four tweeter level settings for fine tuning, high-grade MKT capacitors, and heavy gauge air core inductors. A tweeter protection and load optimization circuit further aid the performance.
Bi-Amp Inputs: The speakers can be powered by a single input to the crossover or Bi-amplified. The crossover's default connection is a single input, using two solid jumper bars to link the input signals. To bi-amp the speakers, you will need to remove the jumpers and connect the woofer and tweeter input signals separately.
Inputs/Outputs: The crossover inputs and outputs are 0.187" wide male quick-slide terminals. Wire is not included with the speakers.
- Width: 5.760"
- Height: 1.394"
- Depth: 3.598" (plus wiring)
