The Control 24CT is constructed with a coaxially mounted 4″ woofer with butyl rubber surround and 0.75″ titanium coated diffraction-loaded tweeter. It includes a 30W multitap transformer for use in either 70V or 100V distributed-line systems. Taps are selected by a front-panel rotary switch. The transformer effectively limits the power to the speaker, so overload is not a concern.
