HELIX's German engineering pedigree really shows up in their Esprit Series speakers, which offer big technological bang for the buck. The E6X 6-3/4" 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 6-3/4" 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. 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 E6X speakers will sound great powered by an aftermarket car stereo, but an outboard amplifier will give you the best audio quality. Grilles are included.
