About the Helix Esprit E57X

High fidelity with excellent imaging
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 E57X 5"x7" speakers use an adjustable 3/4" silk dome tweeter that you can tilt and rotate to improve imaging in cars with less than optimal tweeter placement. Each speaker features a rigid 5"x7" 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 and tweeter, providing the stability needed to maintain accurate reproduction when the music's turned up loud. The Esprit E57X speakers will sound great powered by an aftermarket car stereo, but an outboard amplifier will give you the best audio quality. Grilles are included.

Features
Woofer Materials: Each woofer cone is made of woven fiberglass and has a durable rubber surround. This woven fiberglass material is very light and extremely stiff, minimizing cone flex and resulting in faster transients and finer detail.
Tweeters: Each speaker has a 3/4" silk dome tweeter with a neodymium motor structure. The tweeters also rotate and can be tilted (up to approximately 25°) so you can direct them toward the listening positions.
Magnet cover: The E 57X are shipped with a rubber magnet cover to protect the speaker. If the cover is removed the depth changes slightly:
- Top Mount Depth: 2.25"
- Bottom Mount Depth: 2.625"
Size Classification Note: Helix (Audiotec Fischer) calls this speaker a 5x7, but it also fits many 6x8 installation applications. Please refer to the Crutchfield Vehicle Selector to confirm fit in your vehicle.

Needed to add bass in my old 280E. Thought about a sub but ended up with the HELIX Esprit E57X and am very happy I did. Strong bass response, excellent mids and a nice high with the silk tweeter. These are terrific speakers with wide range and sharp, clear sound.
