At the heart of the beast

All B-52 folded-horn cabinets are loaded with the new B-52 18-220X subwoofer which provides high-power handling, great efficiency, very low distortion and accurate sound reproduction. Key features include:

• 4-inch “inside/outside” voice coil wound on both sides of the glass fiber coil former, providing more effective cooling through greater air contact
• The light weight and robust cast aluminum frame is shaped to minimize reflections on the back of the cone
• The entire loudspeaker is designed to work as a “heat sink” for extreme cooling efficiency
• The advanced magnet topology ensures an even distribution of magnetic flux throughout the whole magnet assembly, resulting in symmetrical motor movement preventing stray flux which can cause interference
• The glass-fiber impregnated cone incorporates a sealed surround and added edge-damping to greatly reduce the occurrence of unwanted cone resonances
• The vented magnet ensures constant air circulation to drive heat away from the magnet assembly

Built-in compression chamber

The 18” subwoofers are housed in a compression chamber that minimizes the excursion of the driver while maximizing the subwoofers’ output. The optimally-sized acoustic aperture of the compression chambers forms the throat of the horn and helps force the air at an increased velocity and pressure. The compression chamber optimizes the horn’s output, allowing for amazing output levels.
