More science than magic

Nothing up the sleeve here! Blaupunkt's Blue Magic CX 170 component speakers offer high-end construction and materials at an affordable price. The 6-3/4" woofer's rigid injected polypropylene (IPP) cone works with its rubber surround to deliver extended excursion for stronger mids and lows. You can install each adjustable 1" PEI tweeter up closer to your listening position, so you get the full effect of the vibrant highs in your music. With a little work, these components will give you a big jump in sound quality over your tired factory speakers.

The CX 170's design includes more ventilation to draw heat away from the voice coil on the woofer, so it'll handle handle higher power from an amp while still being efficient enough to work with a car stereo. The in-line crossovers ensure smooth imaging, so you enjoy the full depth of your music. You can flush- or surface-mount the tweeters, so you can create the best possible soundstage and keep the installation neat.

Installation note: You'll need a pair of our universal backstraps to install the tweeters in the factory locations.

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.

Not bad

Crutchfield Customer Review (What's this?)

They sound a lot better than my original speakers, but the bass isn't too high. It's not bad for the price I paid for these.

Pros: Easy to install, tweeters look awesome

Cons: The bass isn't great

clear sound even though I'm still using the factory head unit it's a good start to up grade the HD later on

Pros: easy install clear sound with a factory radio

Cons: you have to make your own bracket for the tweeters no big deal

Good quality, easy install, I appreciated the multiple mounting options it made the job easier. Also the cutout available on the box was a nice surprise. Great sound stage, which was perfect for my installation in an RV. Would recommend

Crutchfield Customer Review (What's this?)

Blaupunkt has been around a long time. I have purchsed head units and speakers from them before, and this component set did not disappoint either. Build quality is great, and the tweeter mounting options made install pretty easy. Once I got them installed and got to listen to them, I was pleased with the sound quality as well. This component set is a great value. My only complaint is minor. I don't care for the bright blue woofer cone. I'm glad it's behind a door panel. lol

Pros: build quality, mounting options, sound quality

Cons: bright blue woofer cone.

Woofer Magnet Cover: Each woofer has a rubber cover over the magnet. This cover is removable, useful when installing the speaker in tight mounting applications.

Note: The speaker measurements in "Features and Specs" were taken with the rubber cover removed; including the cover, the woofer's dimensions are:

  • Mounting Depth: 2.405"
  • Magnet Diameter: 3.38"

Tweeter Mounting Options: The tweeter can be flush mounted, surface mounted, or surface mounted at an angle using the included adapters. The tweeter comes mounted in the flush mount housing, the angled surface mount housing is included, and combining the top of the angled housing and the bottom of the flush housing creates the standard surface mount housing. The angled housing surface mounts the tweeter at approximately 45°. Once the tweeter is mounted in any of the housings, it can be angled to optimize imaging.

  Flush Mount Surface Mount Angled Surface Mount
Mounting Height 0.35" 1.1" 1.65"
