Horn X Horn Engine with Foundation Bass - 6

The High-Speed Coherent Standard.

The Foundation 6 is a complete, factory-tuned loudspeaker system that proves you don’t need a refrigerator-sized cabinet to achieve massive, lifelike dynamics. This system pairs our flagship Horn X2 PRO engine with the Foundation 06 Bass Module, utilizing Mark Audio’s legendary lightweight cone technology to create a system that starts and stops on a dime.

Factory Tuned for Perfection

Stop thinking and start listening. The Horn X2 Foundation 6 arrives with its crossover factory-set for a perfect blend. We have already done the math and the listening tests. The pre-installed audiophile capacitor and resistor network are optimized to ensure a seamless "hand-off" between the horn and the woofer. You simply plug it in and get a perfectly balanced, coherent presentation immediately.

The Exposed Crossover Engine: Zero Soldering

We do not bury your signal path inside the box. The Horn X2 features a Top-Mounted Crossover that puts the critical components on display and completely under your control.

Modular "Plug-and-Play" Architecture Both the Capacitor and the Resistors are mounted directly into high-quality banana plugs on top of the horn sled. Nothing is hardwired. To change the sound, you simply pull out the component and plug in a new one.

The Capacitor (The Hand-Off): Sets the crossover frequency. You can swap this instantly to experiment with different values or capacitor brands.
The Resistors (The Acoustic Throttle): Sets the output level of the horn.
- Factory Default: Plugged in for a neutral, flat response.
- Custom Tuning: Simply plug in the "Bold" or "Relaxed" resistor sets to instantly change the voicing.

The Engine: 12-Inch Cast Aluminum Horn & Beyma Polymer Tech

At the heart of this system is the Horn X2 PRO, a massive 12-inch Constant Directivity Cast Aluminum Horn. This is not a plastic waveguide; it is a heavy, acoustically inert metal horn that controls sound directivity with absolute precision.

Driving this horn is the Beyma CD171 FE/PK.

Why this driver? Unlike standard titanium drivers that can sound "shouty," the CD171 FE/PK utilizes a specialized Polymer Ketone (PM4) diaphragm.
The Sonic Benefit: This high-tech polymer delivers the speed and detail of a compression driver but with the natural, organic smoothness of a soft dome.

The Foundation: High-Speed Woofer & Internal Physics

We utilize the Mark Audio CHR120 High-Speed Woofer because its ultralight aerospace-grade magnesium-aluminum cone is fast enough to keep up with the horn.

The Secret to Deep Bass: Internal Baffle Step Compensation Small cabinets usually sound thin due to Baffle Step Loss (bass wrapping around the cabinet).

We Fixed It Internally: The Foundation 6 features a dedicated Baffle Step Compensation (BSC) Network built directly into the cabinet.
The Result: This network selectively attenuates the midrange to perfectly match the bass, delivering the weight and authority of a large floorstander from an elegant, 28-liter footprint.
