Product Description
The Pioneer Pro Audio CM-S54T is a compact, professional 4-inch two-way surface mount speaker designed for commercial fixed installations that require flexibility, durability, and clear sound performance. Sold as a pair, this versatile speaker supports 8-ohm low impedance operation as well as 70V/100V distributed audio systems, making it ideal for retail stores, restaurants, hospitality venues, offices, public spaces, and select outdoor areas.
Featuring a 4.5-inch low-frequency cone driver and a 1-inch silk dome tweeter, the CM-S54T delivers balanced sound with a frequency response of 95 Hz – 20 kHz and wide 120° x 120° conical dispersion, allowing fewer speakers to cover more area efficiently.
With a newly developed Vortex Bass Accelerator, the bass-reflex port is constructed with internal ribs to optimize airflow, reduce distortion, and enhance low-frequency response while minimizing unwanted vibrations.
The CM-S54T is housed in a rugged IP54-rated polypropylene enclosure, offering resistance against dust and water for use in covered outdoor spaces. The unique curved cabinet design blends seamlessly into modern architectural environments.
Installation is simplified with the included U-bracket featuring rigid notches for quick angle adjustment. The bracket can be secured by hand and locked in place with an Allen key or screwdriver for added safety. Additional rear mounting points allow flexible deployment in challenging installation spaces.
