Stereo Sound From a Single Speaker Location

For classic vehicles built before 1960, owners face a common problem when trying to achieve a balanced stereo mix in their vintage vehicle. Vehicles made before 1960 were manufactured with only one speaker location, most commonly in the dash, which leaves classic car fans with two unfavorable options: Modifying the car by installing additional speakers or adding clunky speaker boxes on the back shelf.

Our desire to keep a stock look and the need for balanced stereo imaging in our classics inspired us to create a line of dash speakers. These speakers have been engineered from the ground up so that every component works together to deliver rich, balanced stereo sound from a single speaker location.

To achieve this, RetroSound® Triax™ Dash Speakers feature dual aluminum voice coils, each connected to their own flush-mount Mylar tweeter. The left and right channels connect to this single dash speaker to produce a balanced stereo mix.

Retro designed the dash speakers to have an ultra-thin mounting depth without compromising the power they deliver, thanks to the unique neodymium magnet structure. These low-profile magnets allow for mounting in various vehicles that don't have the space required for modern speakers with larger magnets. In addition, the magnet structure is dip-cut, allowing the pole piece to have more room to extend without bottoming out and causing distortion.

Standard speakers use Mylar® tweeters, which tend to sound a bit tinny and abrasive. This effect is more noticeable in a dash location as the sound reflected off the windshield amplifies the sharp, unpleasant tones produced by standard tweeters. Our dash speakers use soft silk tweeters. The softer material creates a smoother and more natural tone to combat this effect and produce clean, natural-sounding mids and highs. A durable Santoprene™ surround and rigid pulp composite cone are used for maximum efficiency and superior audio reproduction. Our dash speakers also work great as a pair for vehicles with left and right speaker locations and can be bridged for a 2-ohm impedance that will deliver more power from an outboard amplifier.
