Why install component speakers?

A component speaker system gives you the best possible performance from your car audio system. A system consists of separate woofers, tweeters, and crossovers, each designed to cover one specific range of frequencies. As separate components, the woofer can move freely to deliver more powerful performance, while the tweeter can be custom-mounted in a better spot up closer to your ears, revealing a whole new world of detail. Separate crossovers are far superior to the simple filters wired into full-range speakers, so the components work together for smoother, more focused sound.

Our take on the Boston Acoustics SC50

by Buck Pomerantz

Boston Acoustics SC Series component speaker systems bring brilliant sound to your car's audio system. Their precision construction and sensitive response allow them to deliver superb performance, filling your car with perfectly balanced sound and making your drive much more pleasurable.

The Boston Acoustics SC50 component system features a tough copolymer 5-1/4" woofer that really delivers the beat. A butyl rubber surround keeps the cone under tight control for clear sound and reliable operation even at extreme playback levels. The compact neodymium magnet helps reduce the size of the SC Series speaker, so it can fit in more vehicles without any loss of fidelity.

The separate 3/4" Kortec® dome tweeters fit in virtually any location you choose — whether flush- or surface-mounted, they can be aimed to provide clean, well-balanced instrumental detail throughout your car. The outboard crossovers make sure the highs and lows combine smoothly, and protect the tweeters from sudden overloads. You can choose from 3 tweeter output levels to achieve the most natural sound.

Highlights:

  • component speaker system includes 2 woofers, 2 tweeters, and 2 crossovers
  • 5-1/4" copolymer woofer with rubber surround
  • 3/4" Type-S2 Kortec dome tweeter with multiple mounting options
  • external crossover with 3 tweeter levels (0, -2, -4 dB)
  • power range: 2-65 watts RMS (180 watts peak power)
  • frequency response 58-20,000 Hz
  • sensitivity: 90 dB
  • top-mount depth: 2-3/16"
  • warranty: 2 years
  • Our 60-day money-back guarantee

    Features

    Woofer: The SC50 component system is equipped with copolymer woofers with butyl rubber surrounds. Each woofer has a neodymium magnet, which has a high power-to-weight ratio and a compact size about one-tenth the size of traditional iron-ferrite magnets.

    Tweeter: The SC50 component system features 3/4" Type S2 Kortec soft-dome tweeters for a smooth high frequency response and linearity. 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 and angled/surface mounting brackets.

    Tweeter Dimensions:

      Frame Diameter Cutout Diameter Mounting Height Mounting Depth
    Angled/Flush Mount 2.230" 1.489" 0.950" 0.620"
    Angled/Surface Mount 1.844" Screw holes only 1.708" Screw depth only

    Crossover: The SC50 system comes with adjustable two-way crossovers. The two crossovers can be mounted separately or docked together and mounted as one piece. You can adjust the tweeter output by placing the supplied jumper on the appropriate terminals; select 0dB (un-attenuated tweeter output), or an attenuated output of -2dB or -4dB. The factory default position is 0dB.

    Note: No crossover frequency or slope information was provided by the manufacturer.

    Crossover Dimensions:

    • Length: 6.845"
    • Height: 1.464"
    • Width: 1.705" (mounted individually)
    • Width: 3.324" (docked together)

    Installation: The compact size of the magnet allows SC 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.

    Nice component set

    Written By GoSteelers, Pittsburgh, PA on Saturday, October 01, 2011
    Installed in a 2008 Mazda 6
    Crutchfield Customer Review (What's this?)
     
    We dropped these speakers into a 2008 Mazda 6 about four months ago. After researching a number of good speakers these seemed a very good choice for this car when coupled to the Alpine MRX-V60 amp. One of the main considerations was that the tweeters had to fit in the factory tweeter door bezel (on the front corner of the window) - they fit perfectly. The crossovers fit inside the lower door panel map pockets so we could get to the octave jumpers without having to crawl under the dash or rip the door panel off. The installation is clean, fit all the factory holes, bezels and door panels. Crutchfield included the 5.25" speaker adapter mounting plates free of charge. Couldn't be happier with the clean installation.

    Now for the sound, very clear highs, the tweeters do not ring or add any color to the music like reviews of other speaker models I've read. The mid-range is very clear and the bass does not boom or rattle. The bass amplitude isn't quite as loud as some other speakers, but the Alpine SPS-517 coax speakers in the rear doors and the pair of 10-inch Polk DXi104 SVC 10" subs in the trunk more than balance the lows out in the car. After four months of some serious pounding we're very pleased with these speakers, no rattles, no problems.
