A modern and elegant solution for superior audio performance in suspended tile ceilings, the LT2-830-T870-VB 2x2 Speaker System is a testament to Lowell Manufacturing's commitment to high-quality sound and stylish design. This sleek, high-tech speaker system includes the CT830A 8" Driver, renowned for its high-performance audio delivery, and the TLM-870 Transformer, ensuring compatibility with 70V systems.
The CT830A driver is a premium 8" 20W coaxial speaker, featuring a strategically post-mounted tweeter that offers improved performance over traditional full-range speakers. The 3" tweeter is designed for wide dispersion, providing enhanced speech and music intelligibility across the listening area. With a frequency response of 57Hz-14kHz (+6dB) and 44Hz-20kHz (+7.6dB), this speaker system delivers clear, accurate voice and music reproduction, making it an outstanding choice for paging, public address, and background music in professional settings.
The speaker's dispersion angle of 80 degrees at 2000Hz (-6dB) ensures even sound coverage, while precision-engineered ceramic magnets and permanently aligned voice coils contribute to the system's smoothness and clarity. The 20-gauge stamped steel frame, with its zinc-plated finish, offers durability and resistance to corrosion. The speaker is designed to provide optimum low-end performance, especially when paired with Lowell's acoustic DX Series backbox or a protective backbox with acoustic fiberglass batting.
The TLM-870 transformer features primary taps at 1, 2, 4, and 8W, allowing for flexible power settings to match specific audio needs. The accompanying volume backbox, with its 0.8 cubic feet capacity and acoustic lining, enhances the speaker's audio performance, ensuring that sound is rich and full-bodied.
Installation is streamlined with the fine-perforation grille and sub-plate, which blend seamlessly into new or existing tile ceilings. The grille's design maximizes free-air space for excellent sound transmission while maintaining an unobtrusive appearance. The white finish of the grille complements any interior design, ensuring that the speaker system is not only heard but also fits elegantly into its environment.
Mounting aids, including restraint tabs, facilitate a quick and secure installation, replacing a non-tegular (2x2) ceiling tile with ease. The speaker leads exit through a metal clamp, allowing for fast and reliable connections. Simply splice the connecting wires, push them into the enclosure, and tighten the clamp for a professional and refined setup.
Crafted in the USA with both domestic and imported components, the LT2-830-T870-VB 2x2 Speaker System meets or exceeds all applicable EIA standards, reflecting Lowell Manufacturing's dedication to excellence in audio equipment manufacturing. This system is the perfect choice for those seeking a modern, stylish, and high-tech in-ceiling speaker solution that delivers exceptional sound quality and integrates seamlessly into any professional environment.
