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.
