Lowell WB4T-4A30-T870 4" Coaxial Speaker With 70V Transformer

The Lowell WB4T-4A30-T870 is designed for AV integrators and sound contractors who need a step up from standard commercial coaxial drivers without overengineering the installation. The 70V transformer is built directly into the driver, eliminating the need for a separate external transformer and simplifying wiring in distributed audio systems. The included torsion grille keeps the installation clean and secure without additional hardware.

This driver targets commercial venue installs where intelligible paging and consistent background music coverage are the primary goals. Hotel lobbies, retail environments, and transportation terminals benefit from the driver's voiced performance characteristics, which prioritize clarity at conversational and announcement levels rather than extended dynamic range. The enclosure is sold separately, giving integrators the flexibility to specify the appropriate back can or baffle for each deployment. Units are priced individually and ordered in multiples of 12, making them practical for large-scale installs across multiple zones.
