Legacy Series - NX350

350w, 12-inch / 1-inch Speaker

The newly designed NX350 is the next evolution of the molded loudspeaker. Based on the popular NX20, the most successful molded cabinet Yorkville has ever made, the NX350 incorporates many new features and subtle improvements over the initial design.



  • Ultra-light variable density acoustic foam construction
  • Dual purpose full range and wedge monitor format enclosure
  • Ultra-clear reproduction throughout bandwidth
  • Ultra-high efficiency performance requires less power for more output
  • Ultra lightweight Neodymium Woofers
  • High quality 1" High Frequency drivers
  • Next generation woofer / driver / horn technology
  • Integrated flying hardware (3/8" threaded holes)
  • Tough, full length metal grille
  • Recessed Input panels
  • PTC™ HF protection system
  • Available in black or white (NX350W) finishes


The new NX350 is slightly larger that the original NX20. The increased cabinet volume greatly increases low frequency response and makes for a better, more balanced overall cabinet tone. It features a new 80° x 50° horn, patterned after the custom ABS waveguide horn used in the popular élite loudspeaker line.

As with all NX series enclosures, the NX350 is manufactured using tough, light weight low resonance variable density composite materials. In addition they are UV and moisture resistant. The new shape employed on the NX350 makes for an improved monitor angle, and makes it ideal for mounting in tight arrays, or in multiple cabinet clusters. It easily handles 350 watts with its Neodymium driver 12-inch woofer, and has a more durable, smoother finish due to an improved molding process, which completely eliminates all release marks as well as the screw flutes, which are used to mount the front baffle in place. The NX350 the ideal replacement for the NX20, and is the ideal cabinet to become the flagship of the NX Series.

The NX350 features our PTC™ (Positive Temperature Coefficient) protection on the high frequency compression driver. PTC™ is an ingenious current sensing / self-resetting breaker that offers some serious advantages over current protection schemes used in many loudspeaker cabinets. This protection scheme, while always present in the signal path, remains inaudible until it becomes necessary for it to react. It kicks in at a point where it effectively reduces output to the horn and protects that diaphragm from damage due to excessive power input or signal distortion. Unlike a breaker it does not require a physical reset to allow signal back to the horn driver, and unlike a bulb or fuse, does not need to be replaced if the circuit is tripped, and the fuse is blown.

Where PTC™ shines is in heavy feedback environments where most horn diaphragm damage occurs. In rare situations even where a microphone might be dropped in a monitor, the sustained 'squeal' can destroy diaphragms in seconds. PTC™ will significantly reduce output level to the horn to protect the diaphragm. When the situation has been rectified, and the feedback eliminated the horn will return to full operating level within half a second.

The NX350 enclosure itself has been molded for maximum versatility. The trapezoid box is ideal for mounting in arrays, or for use as a monitor. An improved wedge monitor angle has been incorporated into the new design. The NX350 is available in either white (NX350W) or black finish.
