Helix Precision P236P
6-3/4" component speaker system
Our take on the Helix Precision P236P by Crutchfield's John Pollard
Your own mobile concert
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.
Note: Helix describes this model as a 6-1/2" speaker. Most manufacturers designate this same frame size as a 6-3/4" speaker. For simplicity's sake we list it as a 6-3/4" speaker.
Installation note: You'll need a pair of our universal backstraps to install the tweeters in the factory locations.

Woofer: The P 236 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: 2.483"
- Bottom Mount Depth: 2.629"
Size Classification Note: Crutchfield has traditionally referred to this woofer size as a 6-3/4", while some manufacturers, including Helix (Audiotec Fischer), call it a 6-1/2". Please refer to the Crutchfield Vehicle Selector to confirm fit in your vehicle.
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.
|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.
