Lowell ESP Series Coaxial Pendant Speakers Acoustic-Match Ceiling Install | 6-1/2" | Without Transformer

The Lowell ESP Series coaxial pendant speakers are purpose-built for installed audio integrators who need consistent frequency response and coverage across spaces where ceiling conditions vary. By engineering each ESP model as a direct acoustic match to the corresponding ES Series in-ceiling speaker, Lowell eliminates the tonal mismatches that commonly arise in venues with a mix of hard-lid and open-structure ceilings. The result is a seamless, even coverage pattern whether speakers are recessed into drywall or hanging from exposed structure.

Available in 6-1/2" and 8" driver sizes, and in transformer-equipped or direct-drive configurations, the ESP Series covers a wide range of installed sound requirements from corporate meeting rooms and houses of worship to retail environments, restaurants, and transit spaces. The tapered enclosure and press-fit grille with magnetic-mount top allow for fast, clean installation with concealed brackets and wiring, while threaded side insert points accommodate the optional U-bracket for wall or truss mounting when pendant suspension is not practical. Cable or pipe mounting comes standard, giving integrators flexibility to meet structural requirements on site without sourcing additional hardware.

For system designers, the ability to pair pendant and recessed speakers from the same acoustic family simplifies design and commissioning. Lowell also provides an online spacing calculator that applies linear dispersion data to help engineers determine optimal speaker placement for uniform coverage, reducing time spent on-site adjusting aim and output.
