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
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.
