About the Boston Acoustics SX50

Install Boston SX component speakers and experience a new level of realism and clarity in your music — an excellent way to add new life to the sound of your car audio system.

Install Boston SX component speakers and experience a new level of realism and clarity in your music — an excellent way to add new life to the sound of your car audio system. The XS50 5-1/4" component speaker package includes two copolymer woofers, two Type-S2 tweeters, two external crossover modules, woofer adapter rings, and tweeter mounting hardware.

Boston Acoustic tunes the outboard crossover to ensure a superb blend between woofer and tweeter for smooth, precise output. The tweeter output level is adjustable. Protection circuitry guards against accidental damage to the tweeter.

A compact, lightweight neodymium magnet reduces the woofer's size so it can fit in more vehicles — with no sacrifice in performance. The included mounting hardware allows you to surface- or flush-mount the compact tweeter.

Product Research

Woofer
Tweeter
Crossover

Woofer

Woofer: The SX50 component system is equipped with copolymer woofers with butyl rubber surrounds. Each woofer has a neodymium magnet, the compact size of the magnet allows SX series speakers to fit where other high quality speakers don't. Neodymium magnets offer extraordinary power-to-weight ratio, approximately ten times the magnetic strength of a conventional iron-ferrite magnet of equal size.

Voice Coil: The oversized 1-1/2" voice coil increases overall power handling and reliability.

Tweeter

Tweeter: Each speaker uses a type-S2, 3/4" Kortec dome tweeter. Kortec is a silky fabric saturated on the underside with a proprietary stiffening agent. Because the inside surface of the dome is ultra stiff, the tweeter tracks the signal with ease and produces an excellent transient attack. Simultaneously, the soft, self-dampening top layer eliminates unwanted resonance, so the sound is smooth and articulate. The tweeters come with angled flush mount and angled surface mount brackets.

Tweeter Dimensions:

  Frame Width Frame Length Cutout Width Cutout Length Mounting Height Mounting Depth
Angled Flush Mount 1.846" 2.208" 1.472" 1.349" 0.973" 0.622"
Angled Surface Mount 1.846" 1.938" N/A N/A 1.718" 0.713" Screw Depth

Crossover

Crossover: All SX speakers feature specifically tuned crossovers to deliver the best blend between the tweeter and woofer. The SX50 system comes with separate two-way adjustable crossovers. The crossovers can be mounted separately or docked together and mounted as one piece. You can adjust the tweeter output level by placing the supplied jumper on the appropriate terminals. Choose between a flat (0dB attenuation/factory setting) or an attenuated output of -2dB or -4dB. No crossover frequency or slope information was provided by the manufacturer.

Crossover Dimensions: Length=6.664", Height=1.464", Width=1.716" (individual), Width=3.374" (docked together)
