The Control 126W Series is a premium in-wall speaker designed for applications where top performance is required. The high performance 6-1/2 inch woofer features a polymer-coated aluminum cone with pure butyl rubber surround. The 1" pure titanium dome tweeter is mounted on a low-diffraction swivel-mounting system enabling the user to direct high frequencies where required without the diffraction distortion inherent in other amiable tweeter designs. The optional Control 126WT contains a 70V/100V transformer for use on distributed loudspeaker lines.
