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 E52C 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.

Esprit Series E52C 5-1/4

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 E52C speakers with an outboard amplifier to give you the best audio quality. Grilles are included.

  • component speaker system includes 2 woofers, 2 tweeters, and 2 crossovers
  • 5-1/4" woven fiberglass woofer cone with rubber surround
  • 1" silk dome tweeter
  • 2-way external crossover network

  • frequency response: 60-25,000 Hz
  • sensitivity: 90 dB
  • top-mount depth: 2-3/16"
  • grilles included

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.

Product Research

Woofer
Tweeter
Crossover

Woofer

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

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.

Tweeter Dimensions:

  Frame Width Frame Length Cutout Diameter Mounting Height Mounting Depth
Flush Mount 2.160" 2.160" 1.835" 0.40" 1.0"
Surface Mount 1.865" 1.865" N/A 1.115" 0.5" (Screw Depth)
Angled Surface Mount 1.840" 1.830" N/A 1.335" 0.5" (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. 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.

Crossover Dimensions:

  • Length: 3.375"
  • Height: 1.50"
  • Width: 1.175"
