Product Overview
The SoundQubed BGX-CX8 pairs an 8-inch woofer with a 3-inch titanium horn driver in one pro-hybrid, two-way coaxial speaker. Its water-resistant carbon fiber cone and high-sensitivity design suit high-output car audio builds, including bagger and demo installations.
Each unit is sold individually, so you can choose the quantity your system calls for. The speaker does not include a grille.
Key Features & Benefits
- Two-way coaxial design: Combines the woofer and horn driver in one speaker for a consolidated installation.
- Water-resistant carbon fiber cone: Adds moisture resistance for installations where exposure is a consideration.
- Titanium horn diaphragm: The horn driver covers high frequencies from 400 Hz to 20 kHz.
- Die-cast aluminum basket: Provides a rigid speaker frame with a corrugated black finish.
- Neodymium magnets: Used in both the woofer and horn driver as part of the speaker’s compact motor assemblies.
- Single-speaker sale: Purchase one unit or select multiple units for your build.

Why Choose This Product?
The BGX-CX8 combines woofer and horn-driver sections in a single 8-inch speaker, with distinct power ratings and crossover requirements for each. That makes crossover planning an important part of choosing it for a high-output system.
Its carbon fiber cone, treated cloth surround, aluminum basket, and titanium diaphragm are specific construction details to weigh when comparing speaker designs. For a bagger or demo build, check the measured mounting space and plan how you will split the signal between the two drivers.
Installation & Compatibility Notes
The woofer’s recommended band-pass crossover is 80 Hz–900 Hz, and the horn driver’s recommended hi-pass crossover is 900 Hz. The product information calls for an active or passive crossover; a DSP or active crossover is recommended for crossover control and driver protection at high power levels.
Both sections are rated at 8Ω. Confirm that your amplifier is stable at 8Ω and that your crossover and amplifier arrangement suits the separate woofer and horn-driver ratings. Before installation, measure the baffle cutout, mounting depth, overall depth, and mounting-hole pattern against your intended location.
The speaker is described for bagger, demo, and high-output daily-driver installations. Its dimensions should be checked against the specific fairing, saddlebag, or other mounting location; the product details do not establish fitment for a particular vehicle.
Frequently Asked Questions
What crossover settings are recommended for the BGX-CX8?
The woofer’s recommended band-pass range is 80 Hz–900 Hz. The horn driver’s recommended hi-pass crossover is 900 Hz.
What impedance should my amplifier support?
The woofer and horn driver are each rated at 8Ω. Confirm your amplifier is stable at 8Ω before connecting the speaker.
What space do I need for mounting?
The front-mount baffle cutout is 7.16" / 182mm, and mounting depth is 4.76" / 121mm. Check these measurements, along with overall dimensions and the mounting-hole pattern, against your installation location.
Is the BGX-CX8 sold as a pair?
No. It is sold as a single speaker, and no grille is included.
Can I wire multiple units in parallel?
Confirm your amplifier’s minimum impedance rating before wiring multiple units in parallel.
