Meridian Audio

The DSP7000 is derived from the company's DSP8000. The new design brings the DSP8000's enclosure materials and digital-speaker architecture to a smaller and more accessible package. The DSP7000's design relies on digital signal processing for crossover filtering and all other signal manipulation and multiamplified active-speaker technology in which each driver is served by a dedicated amplifier channel — in this case, 100W each. Each DSP7000 accepts a digital bitstream directly from a Meridian preamp, CD, DVD player, or system controller, accommodating bitstreams up to 96 kHz/24 bits, including the proprietary Meridian High Resolution upsampled, enhanced-resolution format. This arrangement eliminates speaker cabling and its associated losses, colorations, and clutter.

RBH Sound

The Architectural Cinema Series is a sonically matched home-theater loudspeaker system consisting of a pair of towers (AC-5T), center (AC-525), surrounds (AC-51), and a powered subwoofer (A-10S). The AC-5T employs three 5¼-inch midbass drivers for bass extension down to 45 Hz. The AC-525 uses two of the same 5¼-inch drivers for a seamless font soundstage, and the AC-51 uses one. The A-10S subwoofer features a 10-inch Kraft Pulp driver powered by an internal 150W amplifier capable of bass down to 30 Hz.

OAP Audio Products

The V-3000 Series flyable loudspeaker systems is a compact yet powerful three-way system that uses a 2-inch driver coupled to a 70-degree-by-50-degree horn for high-frequency reproduction and a 10-inch transducer that is positioned in a 60-degree-by-20-degree horn flare for midrange coverage, and a 15-inch woofer (1,400W continuous) provides for the low frequency. The V-3000 is for touring applications as well as fixed installations. An optional, switchable passive crossover is available for use in full-range applications. The full-range crossover is field convertible to biamp or triamp configuration creating ideal user flexibility.

L-Acoustics U.S.

Developed to accommodate professional-grade power handling, the 112XT and 115XT loudspeaker enclosures provide versatile solutions for a variety of applications, from distributed sound reinforcement to sound-on-sticks to floor wedges. Engineered for high-performance DJ, mobile, club, regional, touring, and installed sound reinforcement, each cabinet features advanced components and rigging accessories while also benefiting from the flexibility afforded by custom-engineered digital signal-processing presets. The 112XT is an active two-way loudspeaker system containing a 1.4-inch exit neodymium compression driver that is directly loaded by a 12-inch weather-resistant loudspeaker in a coaxial configuration. The slightly larger 115XT bears many similarities to the 112XT but employs a ceramic magnet and 15-inch loudspeaker.

BSS Audio

The 8-by-8 Soundweb Lite 3088 programmable digital-audio system draws on the larger networked Soundweb 9088iis and associated products but provides a less-expensive alternative for situations where the design requires a maximum of eight inputs and eight outputs. It is for houses of worship, theme bars, boardrooms, clubs, and other applications and possesses all the capabilities of the networked version — a free-design digital signal-processing layout, a large palette of processing objects, custom control panels, and more. It runs under the common Soundweb Designer platform. The 3088 employs a stable set of hardware and software. Control options for the 3088 are similar to the 9088iis and include PC control (custom control panels), simple control from the 9012, and new 9015 wall panels and control ports, or serial control from AMX, Crestron, and other serial-based control systems.

SLS Loudspeakers

The LS8695 line source, line array speaker system is designed to solve the problems created by long-throw audio applications, including live performance music and theater, traveling bands, and fixed installations. The LS8695 is a column-type speaker that conforms to the true line source theory, presenting a cylindrical waveform that is 0 degrees in the vertical plane and 120 degrees in the horizontal. The design provides for a loss of 3 dB of output for each doubling of the distance from the speaker. This efficiency uses less power to produce high sound-pressure level over a long distance.

Speaker Protector


The SP2120 speaker protector eliminates the possibility of unauthorized excessive sound-pressure levels on speaker systems, which could result in damage to both chassis drivers and electronics. The SP2120 also gives venues the opportunity to comply with local legislation regarding noise levels. The SP2120 is intended for insertion in the sound system immediately prior to the amplifier stage and taking minutes to install. Its signal path combines a mixture of multiple time constant circuitry and automatic gain control, which allows small overloads to sound louder, even though they are not.
