Klein + Hummel KPA series

Klein + Hummel KPA series

Danley Sound Labs showed dozens of new offerings in its demo room. The GH 60 houses 18 drivers (eight low, eight mids, and two highs) per cabinet, using the company's new Synergy horn. According to Danley, GH 60 avoids some of the problems often associated with line-array systems — such as the fact that coupling filters don't work at all frequencies. The GH 60 has a 60-degree horizontal and 45-degree vertical pattern. It also offers 20dB of gain. When it's hung at 25ft., Danley claims the cabinet provides even coverage from 10ft. to 100ft. out.

Klein + Hummel (K+H) is known best in the United States for its reference and studio monitors. K+H aims to change that perception. At InfoComm, the company touted its installed-sound loudspeaker line. The IS-122 is a horn-loaded 1in. model with 12in. woofer. The three-way IS-123 loudspeaker has a coaxially integrated 1in./2in. driver and a 12in. woofer. The IS-153 is a three-way model with a 1in./2in. coaxial driver and a 15in. woofer. Peak SPL is 135dB. All three models are biamp-only or available with self-powered back-plate options. The self-powered version includes factory DSP tuning. In addition, K+H showcased its K8 digital audio-distribution system, the new CLS series slim-line loudspeakers, the PAS 100 indoor/outdoor portable loudspeaker, and the KPA series of audio power amplifiers.

Known best for its amps, QSC also has several lines of loudspeakers. New at InfoComm was the AD-S32T, the company's most compact surface-mount loudspeaker. The AD-S32T has a 3in. low-frequency driver outfitted with a polypropylene cone and a 0.75in. titanium dome tweeter. The weather-resistant enclosure has a power rating of 30W (continuous), 85dB sensitivity, and extended low-frequency range of operation down to 73Hz. QSC also exhibited its compact WideLine-8 line-array system. The WideLine-8 includes the full-range WL3082 and the WL212-sw subwoofer. The system accommodates arrays of up to 12 boxes.

Renkus-Heinz expanded its Sygma loudspeakers line with the new SG/SGX12S subwoofer, which comes in an externally powered version or a version that includes power amplification. There are also new coverage pattern options for the SG/SGX121 — which is now available in 120°×60°, 90°×60°, 60°×40°, and 90°×40° versions. Renkus-Heinz also introduced the second generation of its Iconyx R digitally steerable arrays with new dual-tweeter drivers for improved high-frequency response.

Tannoy introduced its VQ line of directional loudspeakers built for large-scale installations that need great audio quality and extremely high SPLs. The VQ 60 mid-high hits 115dB, according to the company; the VQ 100 mid-high reaches 110dB. Tannoy's signature design, which aligns the acoustical centers of the transducers to provide a single wavefront, enables heightened pattern control with no interference between the high frequency and the midrange at the crossover point.
