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.

Helix Precision p 235p

Written By Douglas S, Baltimore,MD on Saturday, December 15, 2012

Crutchfield Customer Review (What's this?)

Great sound and quality hand made products from Helix needs no introduction. Europe has enjoyed this brand for years and now the U.S. can as well. You get what you pay for and it couldn't be true for this component system. You have to hook up a amp to fully enjoy like any high end system.

Pros: Great sound and quality from Helix.

Cons: Can think of anything.

Product Research



Woofer: The P 235 component system includes woofers made of sisal fiber with durable rubber surrounds. The mechanical advantages of sisal, rigidity and inner damping, result in faster transients and precise detail.

Magnet cover: The woofers are shipped with a rubber magnet cover to protect the speaker. If the cover is removed the depth changes slightly:

  • Top Mount Depth: 2.281"
  • Bottom Mount Depth: 2.452"


Tweeter: The system uses 1" silk dome tweeters with neodymium motor structures. The tweeters can be flush mounted or surface mounted at an angle using the included brackets. Like the woofers, the tweeters have male quick slide terminals. The positive terminal is 0.187" wide and the negative terminal is 0.110" wide. Neither speaker wire nor crimp-on terminals are included with the speakers.

Tweeter Dimensions:

  Frame Width Frame Length Cutout Diameter Mounting Height Mounting Depth
Flush Mount 2.284" 2.284" 1.94" 0.455" 0.961" (1.637" including screw)
Angled Surface Mount 1.82" 2.075" N/A 1.2" 0.61" (Screw Depth)


Crossover: The crossovers are separate components with tweeter protection built-in. The inputs and outputs are screw terminals and will accommodate bare wire or spade connectors up to 0.3" wide. A jumper allows you to adjust the tweeter output level; choose +3dB, 0dB, or -3dB. A second jumper changes the woofers' expected impedance from 4-ohms to 2-ohms, used when a second pair of woofers is added. No crossover frequency or slope information was provided by the manufacturer.

Crossover Dimensions:

  • Length: 4.018"
  • Height: 1.34"
  • Width: 4.525"
