Introduction
Thank you for purchasing the Boston Acoustics SPZ component system. Nothing better describes SPZ components than
best-in-class. With nearly 1-inch of peak-to-peak excursion, SPZ delivers more bass from a standard size speaker
opening. Further, Our off-axis, free rotating tweeter AMD™allows you to optimize the soundstage from OEM speaker
locations. Component systems that combine installation flexibility with best-in-class performance are the clear choice for
those who refuse to compromise the interior of their high performance vehicle. Others make claims. We deliver ours with
the Boston Acoustics SPZ Reference Components.
Nearly 1-inch peak-to-peak excursion from finite-element optimized rubber surround
Performs as a larger diameter woofer yet drops into OEM speaker locations.
Component and axis mount configurable
Allows utilization of OEM speaker locations without radical customization.
Free rotating axis-mount geometry acts as both a lens and tweeter baffle to allow adjustable soundstage height from a fixed mounting position
Integrates woofer and tweeter as a seamless acoustic system.
Compact neodymium magnet structures
Deliver superb sound quality output from compact Magnetic-finite-element optimized structures.
Copper-clad aluminum woofer voice coils
Provides low-mass, long Xmax, and optimized DCR while maintaining power handling.
150W RMS power handling
Enabled by RadialVent®cooling and TwinStage™heatsink.
System specific 24dB per octave crossovers with application specific filters
Minimizes driver placement issues based on OEM speaker locations.

The axis mount on the SPZ woofer is designed so it can be positioned to
properly direct the tweeter’s output towards the listening position.
1) Loosen the retaining screw located on the face of the axis mount
with the provided tool (2.5mm). Turn the screw at least three full
rotations counter-clockwise.
2) Position the axis mount so that the tweeter points towards the
listening area.
3) Once the desired location has been chosen, tighten the screw on the
axis mount.
(Note: do not overtighten the set screw.)

Crossover Configuration:
Axis / Comp Mount Switch:
The “Axis/Comp” switch optimizes the output from the
crossover for the configuration of the component system. Use
the “Axis” setting if the tweeter is installed in the axis mount,
use the “Comp” setting if the tweeter is installed separate
from the woofer.
SQ1 / SQ2 Switch:
The “SQ1/SQ2” switch alters the roll-off of the SPZ woofer.
Use the SQ1 position for a standard door location. Use the
SQ2 setting if the SPZ woofer is used in a kick panel or small
enclosure (less than 0.25 FT3).
ATTN Switch:
The “ATTN” (attenuation) switch adjusts the output of the
tweeter relative to the woofer, three adjustments allow you to
fine tune the output of the tweeter (0dB, -2dB, & -4dB).
NORMAL / BIAMP Jumpers:
If the SPZ crossover is bi-amplified or bi-wired, move the
jumpers to the “BIAMP” position. Refer to the System Wiring
Diagrams on page 21.
