The NX600 is the first 15-inch and horn molded loudspeaker from Yorkville Sound. This 600-watt passive box is using a new injection molded technology and features a first for composite loudspeakers, a rotatable 80º x 50º horn patterned after the custom ABS waveguide horn used in our popular élite loudspeaker line.
The unique trapezoidal shape employed on the NX600 allows the cabinet to be used as a monitor or front-of-house loudspeaker and makes it ideal for mounting in tight arrays, or in multiple cabinet clusters. The NX600 easily handles 600 watts with its Neodymium 15-inch woofer and 1 ½-inch polyester high frequency driver.

The NX600 used the same proven 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.

NX Series Overview
NX - Not all man made materials are created equal, acoustically speaking…
The NX Series loudspeaker cabinets have undergone a constant evolution since the flagship model, the NX20, was introduced in early 2000. Along the way, improvements in the molding process have led to the use of tougher, lightweight, low resonance variable density composite materials, use of denser foam in select locations and redesigned part geometry for a much sturdier and a much stronger molded loudspeaker box.

The NX Series cabinets now have a smoother, more rugged and more professional final finish. Select cabinets are now available in either the standard black finish for touring or club system PA applications, or in white paintable finish for fixed installations.

All cabinets in the NX Series are molded for maximum versatility, and all boxes can be used as either a full range front of house enclosures, as floor monitors or as installation loudspeakers. Integrated flypoints, recessed handles, dent resistant all metal grilles and integrated stand mount adaptors are included on all NX Series cabinets ensuring maximum flexibility. Speakon and 1/4-inch connectors on the passive cabinets (XLR and TRS balanced connectors on the active loudspeakers) ensure simple and secure connectivity. All NX Series cabinets are UV and moisture resistant and can be used in outdoor applications.

The trapezoid box is ideal for mounting in arrays, or for use as a monitor, with recessed input jack plate and an ideal wedge monitor angle that was taken into account in the initial design. Neither application was considered as an afterthought. Stand mount and flying hardware are also available.

Capitalizing on the lightweight molded cabinet design and equipped with a proprietary neodymium woofer, Active versions of the NX series are also available in the line.

Even when fully loaded with the unique processing crossover, CTL™ high frequency protection circuits and TWO amplifiers that drive the bi-amped system, the NX55P is a 550 watt powerhouse that still weighs in at an easily manageable 47 lbs, and the NX600 features a 600 watt 15” low frequency driver and still only weighs 44lbs, the lightest in its class by a long shot. The passive 2-Way NX88 weighs in at an ultra-low 17lbs, our most compact loudspeaker yet.
