Premier Series 5.25" 2-Way, In-Ceiling, Infinite Baffle Loudspeaker w/FastLoc™ Grille Pair

Product Information

The easy to install CS501FL is a full-range ceiling loudspeaker that incorporates an Injection Molded Graphite woofer with a butyl rubber surround and Ferrofluid cooled titanium coated polycarbonate tweeter. The tweeter allows for deeper penetration into the room and concentrated sound to the sweet spot. 

The FastLocT™ grille patent no. 8,422,722, is a feature found only at Current Audio. Our design has allowed for the smallest exposed plastic bezel in the industry, trulymaking it disappear into the mounting surface. The FastLoc grille's unique patent pending mechanism allows for a quick installation and removal of the grille while securely fastening it in place to all types of mounting surfaces. Due to the unique design the grille will conform to uneven surfaces including popcorn, heavy textured and uneven ceilings. While our competitors have chosen to utilize magnets in their designs thus requiring the use of a steel grille that will rust our design allows us to use corrosion and rust resistant aluminum.

This revolutionary combination provides superior and more natural sound for both foreground and background applications. The Infinite Baffle design makes it the ideal choice for typical applications in open beam attic or enclosed ceilings.

The speaker color is white, and is a close match to Frazee White Shadow 181. It can be painted to match any decor. The speaker enclosure is a durable UV-resistant material that allows for both indoor and outdoor installations. The perforated powder-coated aluminum alloy grill is long-lasting, corrosion resistant and rust-free.

Four built-in expanding transverse dog leg clamps permit installation with or without pre-wire construction brackets in drywall or material with thickness of 7/32" to 1 3/16". 

Electrical connection, up to 12-gauge wire, is made by gold plated constant tension spring-loaded terminals.
