TCi Series In-Wall/In-Ceiling Loudspeakers are the performance alternative for custom installed sound systems. They give you Total Control over your Total Custom built-in audio installation with superior user controls and superior performance. Use round TCi speakers anywhere you need high performance sound but don't have the room or the desire for even the smallest of freestanding loudspeakers. They're perfect for use in locations that demand extreme durability because they feature moisture resistant materials. The 15-degree Offset Drive Unit means more uniform coverage and better imaging.
