The vented SUB 18 and SUB 28 direct radiators have been designed for subwoofer use in active multiway systems. The superior transient response of the classic bass reflex construction is also well suited for medium to large bass arrays. The premium 700W RMS long excursion woofers feature extremely low THD, and the reliable, all-electronic Voice Coil Tracking Protection prevents thermal overload of the 100mm sandwich voice coils. For maximum dynamics, the SUB models can be driven by extremely powerful amplifiers; thermal overload triggers a virtually inaudible 'soft' power reduction.

The TX1181 is the perfect companion sub to the TX1122 and TX1152 for compact and portable performance. Using the proven EVS18S woofer, the TX1181 effortlessly provides the low-frequency energy needed to keep up with Tour X boxes, as well as many other EV loudspeaker products. The integrated, low-pass input filter allows for single amp drive, and the high-sensitivity and excellent power handling don\'t require a large, expensive amplifier to generate high SPL. 

The TX1181\'s unique Backbone grille not only looks great, but also provides greater strength and damage resistance than simple grille block designs. Proprietary, ergonomically correct handles and angled input panels, and integrated, screw-in-style pole-mount make the TX1181 easy to transport and employ in a variety of applications.

The new Yamaha CW218V features a super durable, paintable, elastomeric-sprayed coating with foam lined acoustically transparent steel grilles. Gives a great professional look much preferred over carpeted enclosures. Assembled by hand in the US by skilled technicians, each cabinet is designed for better low-end response and includes heavy steel handles and sturdy pole sockets to make moving and positioning easy.

The custom drivers from Eminence feature high-strength curvilinear cones and Kapton® voice coil formers, plus oxygen-free copper voice coils and oversize strontium ferrite magnets to provide high power handling and long life. 15" and 18" drivers use cast aluminum frames to support the massive magnet structure, eliminate flex, and dissipate heat. The titanium diaphragm compression driver is mated to a 90 degree x 40 degree custom-designed horn. Internal electronics feature an over-built crossover network and overload protection.

Connections are dual Neutrik Speakon® and 1/4" jacks. With professional features, excellent sonic performance, and great value, Club Concert Series loudspeakers deliver premium quality night after night. The CW218V reigns supreme with 2 cast-frame 18" woofers and 30Hz-2kHz frequency response (-10dB). It features 1,220W program handling with 2,400W peak. Sensitivity: 98dB. 48“W x 23“H x 26“D.
