Bose Style Replacement Driver for 901 and 802 Series SpeakersDrop-in replacement for Bose 901 Series 3, 4, 5 and 6.Replacement for Bose 802 Pro Overall diameter: 5.2″ (132mm)Hole cutout: 4″ (102mm)Mounting depth: 2.25″ (57mm)Frequency response: 83 – 15,000 HzSensitivity: 91.5 dBDurable ABS frameThis driver’s parameters were carefully optimized to match the performance of the classic Bose® 901® loudspeaker systems. Individually or in multiples, replacing your legendary but aging speakers has never been easier—or achieved better results. The top plate and T-yoke are Japanese-made cold forged low carbon steel. The flat back plate provides a uniform surface area to which the magnet is bonded, and the outside of the back plate is chamfered to maximize flux density in the gap. Critical attention has been paid to the pole piece and voice coil tolerances, thereby assuring high yield and immunity to mechanical issues. High-grade Y-35 strontium ferrite magnet material is utilized in the motor structure to ensure consistent motor force. The cone is made of long fiber New Zealand blue color pulp paper, an ideal material for cone applications and the foam surround of this driver make it almost identical to the original manufacturers appearance, design and performance. It’s rigid and just “lossy” enough to produce full, accurate sound. A 2-layer low oxygen copper voice coil is wound on a high temperature resistant polyimide former. Every driver is hand checked and tested, based on a ±2 dB window.
