Description

Product Overview

Give your factory 5x7-inch speaker locations a two-way upgrade with the SoundQubed HDS Series 5x7" coaxial speakers. Each speaker combines a paper woofer cone and rubber surround with an integrated 1-inch Mylar dome tweeter. The pair handles 50W RMS at 4 ohms and is designed for car audio door or dash installations.

Key Features & Benefits

Two-way coaxial design: The built-in tweeter provides high-frequency output in the same speaker, without a separate tweeter installation.
50W RMS power handling: Match the speakers to an amplifier with suitable output for a powered 5x7-inch setup.
Paper cone and rubber surround: These woofer materials form the speaker’s moving cone assembly.
Mylar dome tweeter: The 1-inch tweeter uses a 3g neodymium magnet.
90 Hz recommended high-pass: Use this crossover setting as a reference when configuring your amplifier.
Sold as a pair: The package includes two speakers; grilles are not included.

Installation & Compatibility Notes

Check the mounting location’s cutout and available depth against the listed measurements before buying. Although the speaker has a 5x7-inch nominal diameter, its overall dimensions are 5.5x8.6 inches, with a 4.9x7-inch front-mount baffle cutout and 2.1-inch mounting depth. No grille is included.

The speakers are rated at 4 ohms, with 50W RMS and 150W maximum power handling. The recommended high-pass crossover is 90 Hz. The source recommends the SoundQubed S4-100 amplifier, rated at 100W x4, for pairing with these speakers.
