This assembly is epoxy-secured and screwed directly to the cabinet floor, lifting the low end of the Mark Audio CHR-120 extended-range driver. With tuning that reaches into the low 30Hz range, it pairs flawlessly with the Horn X2 for a seamless full-range experience.

Premium copper rear terminals are mounted on an 18mm carbon fiber backplate. Internally, Mil-Spec silver-over-copper wiring ensures signal purity from amplifier to driver.

Installation is effortless. Simply place the Horn X2 on top of the Foundation cabinet, connect your amplifier to the center terminals on the Horn X2, and connect its outer terminals to the cabinet’s rear inputs. That’s it. No soldering, no mods, no mystery. The entire system is pre-tuned for smooth integration and flawless transition from horn to woofer.

You may adjust the Horn X2 resister to match your environment and tastes thus decreasing or increasing the horns volume. The top mounted capacitors is pre-selected to insure proper crossover integration but feel free o change its brand if you so desire to one of your own tastes. We offer Clarity CSA capacitors (extended highs very transparent) or Mundorf EVO Oil (smooth yet revealing top end).

Note: The Foundation cabinet is not sold separately. It is exclusively designed for use with the Horn X2 system.
