Description
Product Overview
The SoundQubed HDX-CX69 6x9-inch 2-way coaxial speakers bring a glass fiber woofer and integrated neodymium tweeter together in one speaker. Sold as a pair, they’re intended for 6x9-inch locations in daily-driver systems and motorcycle bagger audio builds.
Key Features & Benefits
- Glass fiber cone and rubber surround: This woofer construction is designed for controlled midrange performance.
- Integrated 1-inch neodymium tweeter: The coaxial layout places high-frequency sound in the same speaker, without a separate tweeter installation.
- 550g barium ferrite magnet: The woofer’s substantial magnet is part of its motor assembly.
- Pair with grills: Two speakers and two grills are included for a finished installation.
- 50 Hz recommended hi-pass: The recommended crossover point provides a starting point for amplifier setup.

Why Choose This Product?
The HDX-CX69 combines its woofer and tweeter in a 2-way coaxial design. That gives you a single speaker assembly for a 6x9-inch location, rather than a separate tweeter installation. Its 4-ohm impedance and 120W RMS power handling are key figures to compare with your amplifier before choosing a system.
The manufacturer’s pairing suggestions include the SoundQubed Q4-150ABv2 (150W x4), Q4-2000 (325W x4), and Q4-3200 (520W x4). These are listed amplifier outputs; compare the output at your intended load with the speaker’s power handling when planning your setup. For bagger audio builds, the suggested models are the SoundQubed BG4-700 and BG4-1400.
Installation & Compatibility Notes
Measure the mounting location before purchase. The required front-mount baffle cutout is 5.9x8.7 inches / 151x221mm, and mounting depth is 3.3 inches / 84mm. Check available depth and clearance with the grill fitted, using the overall dimensions in the table.
The product is listed for motorcycle speaker applications, including Harley-Davidson saddlebag lid and fairing locations that accept 6x9-inch drivers. Check your specific location’s cutout and depth. The recommended hi-pass crossover is 50 Hz; the installation guidance also suggests setting the amplifier’s HPF at 50–80 Hz. The coaxial design does not require a separate passive crossover.
Frequently Asked Questions
What amplifier power should I look for?
The speakers are rated for 120W RMS and 360W maximum at 4 ohms. Check the amplifier’s output at 4 ohms and compare it with those ratings.
Do I need to install a separate tweeter?
No. Each speaker has an integrated 1-inch neodymium tweeter, and the coaxial installation does not require a separate passive crossover.
Will these fit my vehicle or motorcycle?
They are 6x9-inch speakers, but fit depends on the mounting location. Check the listed cutout, mounting depth, and available clearance against your specific vehicle or motorcycle.
What comes in the pair?
The set includes two speakers and grills.
