Hertz DCX 690.3 6x9 3-Way Coaxial Speakers

The Hertz DCX 690.3 is a 6 x 9-inch three-way coaxial speaker designed for replacing compatible factory speakers in a vehicle. Its integrated woofer, midrange tweeter, and supertweeter provide a complete speaker assembly for locations that accept 6 x 9-inch drivers. It is intended for listeners who want a straightforward full-range speaker upgrade without installing separate crossover networks and individual drivers.

With 90 watts continuous power handling, 180 watts peak power handling, and a 4-ohm impedance, the DCX 690.3 can be matched with compatible car-audio amplification or a suitable factory or aftermarket receiver. Its 93 dB SPL sensitivity and 45 Hz to 21 kHz frequency-response rating describe a design built to cover bass, midrange, and treble frequencies from one mounting location. The three-way layout includes a 60 mm paper tweeter and a 15 mm PEI-dome supertweeter.

The woofer uses a water-repellent pressed-paper cone and a TPU surround. Hertz specifies high-density-flux ferrite magnets for both the woofer and tweeter, along with a 25 mm pure-copper woofer voice coil wound on a Conex former. These materials support the speaker's intended mobile-audio use while the coaxial format keeps the installation concentrated in a single 6 x 9-inch opening.

Hertz also equips the DCX 690.3 with a DIN-size basket finished with abrasion-resistant dust paint, tin-plated high-current terminals, and silver-plated lead wires. The motor assembly uses low-carbon-content plates, and the speaker includes a butyl-rubber protective cover for the magnet area. These construction details address the electrical connections, moving assembly, and physical protection required in an automotive installation.

This model fits naturally into an entry-level or replacement-speaker system where compatible 6 x 9-inch mounting locations are available. It can be used as a pair for front, rear, or parcel-shelf speaker positions when vehicle fitment and mounting clearance are confirmed. For a more complete system upgrade, select an amplifier or receiver that is appropriate for its 4-ohm load and 90-watt continuous power rating.

Design & Installation

The DCX 690.3 combines a water-repellent pressed-paper woofer cone with a TPU surround, high-density-flux ferrite magnets, and a PEI supertweeter dome. Its 25 mm pure-copper voice coil is wound on a Conex former, while the basket uses an abrasion-resistant painted finish. Tin-plated terminals, silver-plated lead wires, low-carbon plates, epoxy motor-to-basket bonding, and a butyl-rubber protective cover are specified construction details.

Confirm the vehicle's available mounting opening, mounting depth, and panel clearance before installation. Hertz lists overall dimensions of 237 x 162 mm, mounting dimensions of 224 x 153 mm, a total depth of 98 mm, and a mounting depth of 77 mm. Connect the speakers to a compatible 4-ohm amplifier or receiver, observe correct polarity, and use the included grilles where the speaker faces need protection.
