Product Research
Woofer
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
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"

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.
