HELIX's Precision line of speakers offer excellent detail and clarity for the mobile audio enthusiast. HELIX uses special materials to built these speakers, which are engineered in Germany to deliver a powerful listening experience in your vehicle's interior. You'll hear details in your music that you didn't know were there, and you'll experience a strong soundstage that makes you feel like you're in the front row at the concert.

 Precision Series P234P 4

High-quality parts and construction

The Precision P234P component speaker system includes two 4" woofers, two 1" tweeters, and a pair of outboard crossover networks. HELIX creates the woofer cone from Agave sisalana, a natural fiber that's incredibly stiff, then impregnates each cone with aluminum and coats it with a layer of silk. A durable rubber surround and sturdy stamped-steel basket complete a driver that's ready to provide powerful midrange and midbass reproduction.

The large 1" silk dome tweeter broadcasts all the high-frequency details in your music, while a robust external crossover network provides seamless separation of the highs and lows for superior realism. You can adjust tweeter levels on the crossover to +/- 3dB based on your listening preference. This speaker system will handle up to 40 watts RMS, so an external amplifier is recommended for best results.

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.

Woofer

Crossover

Woofer

Woofer: The P 234 component system includes woofers made of sisal fiber with durable rubber surrounds. The mechanical advantages of sisal, rigidity and inner damping, result in fast 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: 1.804"
  • Bottom Mount Depth: 2.039"

Removable Mounting Tabs: Most 4" factory speakers use four mounting screws, however, in some vehicles, only two are used. In these cases, you can bend the unnecessary mounting tabs on the woofer until they break off. Care should be taken handling the speaker after any tabs are removed because the broken edges may be sharp.

Tweeter

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

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"
