Details
The Colossus 18B is designed as a high power general purpose bass unit. It is built around a die-cast aluminum chassis and uses a 4 inch diameter voice coil driven by a vented motor system with a high density paper cone suspended by a wide, high compliance, double roll surround and a solid paper dome. Although basically a classic design, it has stood the test of time, and advances in material science have brought this unit along to become a very durable and workmanlike unit. The Colossus 18B is optimal for use in 100 to 250 litre ported enclosures.
