Lowell Manufacturing allows installers to order the rough-in elements of the ES-62T-LE separately, put those in place during initial construction, and then order and place the mounting bezel, speaker, transformer, and grille package in the finishing phase of the project. The built-in reversible dog-ear mounting clamps make installation fast. The 6.5in. woofer is arranged in a coaxial configuration with the PEI tweeter and its acoustic lens. The press-fit grille comes with a pull-tool; the speakers are sold in pairs.
The C10.1R from Martin Audio is especially designed for high-ceiling installations in high SPL venues with its 10in. coaxial bass driver and through-the-pole firing 1in. compression driver providing a 90-degree conical coverage area at up to 10kHz. Designed to fit Lowell and Atlas rectangular rear enclosures, the C10.1R handles 200W AES, 800W peak power and delivers 115dB continuous SPL. Options include a 150W 70/100V line transformer. The unit has a 2kHz passive crossover and rising clamp plug-and-socket connectors.
One of the main features that Niles Audio incorporated into its CM8MP two-way ceiling-mount speaker is the maximized front surface area used by the 8in. polypropylene cone woofer. It is done while minimizing the size of the whole enclosure. This is paired with a 1in. fluid-cooled UltraSilk soft-dome tweeter that can be aimed up to 20 degrees off axis for custom tailored coverage. Together they produce a frequency response of 50Hz-21kHz (±3dB). The nominal impedance is 8Ω, and it can handle amp power from 10W to 140W.
Where high-impact SPL and superior bass response is needed, Penton Audio has the closed-back CCS6T ceiling speaker enclosed in a metal back-box with a UL plenum-compliant wire connection on the rear surface. The connection is complete with a pass-through terminal. The 6in. extended throw LF driver works along with a coaxially mounted 1in. titanium dome tweeter to provide a frequency response of 60Hz-20kHz (±5dB) while handling up to 90W amp power. By removing the grille, the screwdriver adjustable transformer power tap selector can be accessed.
QSC Audio Products gives installers several options with the selection of the AcousticDesign AD-C820 and C821. Both are 8in. LF ferrite cone systems with a 1/4in. diaphragm neodymium compression driver and each can handle 200W continuous power. They provide a 90-degree horizontal and vertical coverage pattern and can operate in low impedance or 70/100V modes. The AD-C820 is designed for pre-install (separated backcan) applications while the AD-C821 is intended as a fully integrated, blind-mount system. Each can be ordered with a round or square grille.
The PL 60FD from RCF-USA is suited for alarm and emergency evacuation equipment because it does not allow a fire to move to the audio system. Its ceramic terminal blocks, thermal fuse, and fire-resistant cable all contribute to the safety of the structure. The 6in. dual-cone wideband speaker operates in low impedance or 70/100V modes while producing 150-degree horizontal and vertical coverage, handling 10W peak power and producing 150Hz-15kHz frequency response. The metal back cover fits a white steel grille and is secured in the mounting hole by four lead-screw rotating clamps.
