Our take on the HELIX E 52Cby Crutchfield's John Pollard
High fidelity with excellent imaging
HELIX's German engineering pedigree really shows up in their Esprit Series speakers, which offer big technological bang for the buck. The E 52C 5-1/4" component speakers use a separate 1" silk dome tweeter that you can mount higher in your vehicle for optimal imaging and stereo separation. Each speaker features a rigid 5-1/4" woven fiberglass cone that delivers tight midrange and bass reproduction, while the durable rubber surround helps this speaker provide exceptional sound for years to come.
Built for power
A tough stamped-steel basket houses each woofer, providing the stability needed to maintain accurate reproduction when the music's turned up loud, and the external crossovers keep the right frequencies going to the right drivers so you can rock out the bass without damaging your tweeters. We recommend that you power the Esprit E 52C speakers with an outboard amplifier to give you the best audio quality. Grilles are included.
Installation note: You'll need a pair of our universal backstraps to install the tweeters in the factory locations.

Woofer: The E 52C component system includes woofers with woven fiberglass cones and durable rubber surrounds. This woven fiberglass material is very light and extremely stiff, minimizing cone flex and resulting in faster transients and finer 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: 2.066"
- Bottom Mount Depth: 2.196"
Tweeter: The system uses 1" silk dome tweeters with neodymium motor structures. The tweeters can be flush mounted, surface mounted, or surface mounted at an angle using the included brackets. Once mounted, the tweeters swivel (up to approximately 25°) so you can direct them toward the listening positions.

|Angled Surface Mount||1.840"||1.830"||N/A||1.335"||0.5" (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. The tweeter output level is adjustable by attaching the positive tweeter lead to one of three screw terminals on the crossover, +2dB, 0dB, or -2dB. No crossover frequency or slope information was provided by the manufacturer.
