Lowell Manufacturing WB4-4A30-T870 Speaker/Grille Assembly, Includes 4" 30W Coaxial Driver, 8W Transformer and White Screw-Mount Grille

Take your audio experience to the next level with the WB4-4A30-T870 Speaker/Grille Assembly, a premium in-ceiling sound solution from Lowell Manufacturing, a leader in high-quality audio equipment. This assembly features a robust 4" 30W coaxial driver designed to elevate sound quality and performance beyond standard commercial offerings, making it ideal for environments that demand crystal-clear paging and immersive background music, such as hotel lobbies, retail spaces, and transportation hubs.

The driver, model 4A30, boasts a wide 135-degree dispersion angle, ensuring large coverage areas are filled with uniform sound at 2kHz, promoting clear audibility and reducing the need for additional units. The driver's ten-ounce magnet and 1" copper voice coil work in harmony with a polypropylene cone and half-roll rubber surround, facilitating long cone travel and superior edge damping for durable, reliable performance.

A post-mounted, liquid-cooled tweeter features a 1" diameter balanced drive dome with a first-order highpass filter, delivering a smooth frequency response from 70Hz to 20kHz (+6dB) and an extended range of 50Hz to 20kHz (+8.8dB), with a precise crossover at 5kHz. The driver's frame is constructed from stamped 20-gauge steel with a black enamel paint finish and a zinc-plated backplate for added durability and style.

The included TLM-870 transformer offers primary taps at 8, 4, 2, and 1 watt, with a frequency response of 50Hz-15kHz (+1dB), ensuring compatibility with high-quality audio systems and general-purpose paging applications. Its industry-standard open-housing design and color-coded leads facilitate fast and efficient installation.

Completing the assembly is the stylish WB-4 grille, a one-piece punched steel grille with a sleek white powder epoxy finish. The grille measures 7.25" in diameter and is designed for easy mounting to a backbox with four white Phillips-head screws, providing a discreet and streamlined appearance.
