About the CDM 7SE

The Bowers & Wilkins CDM 7SE Special Edition is a high-fidelity 3-way bass reflex floorstanding speaker system produced between 1998 and 2000 in England. It features a 25 mm alloy dome tweeter, a 165 mm woven Kevlar cone bass/midrange driver, and a 165 mm paper/Kevlar cone bass driver with dispersion modifiers replacing traditional dust caps to improve mid-frequency dispersion and integration between drivers. The speaker has a frequency response of 40 Hz to 20 kHz ±3 dB, sensitivity of 90 dB SPL (2.83 V, 1 m), nominal impedance of 8 ohms (minimum 4 ohms), and recommended amplifier power of 30 to 150 watts. The cabinet is finished in real wood veneers including Black Ash, Red Ash, and Cherry, with black cloth grilles. Dimensions are approximately 220 mm wide, 950 mm high, and 290 mm deep, weighing about 18.5 kg per speaker. The design incorporates B&W's 'Tweeter on top' technology for improved stereo imaging and time alignment of drivers for coherent sound. The crossover uses separate boards with tweeter filters to maximize bi-wiring benefits. The CDM 7SE was awarded the Diapason d’Or Hi-Fi Palmarès in 1999 and is noted for its panoramic, studio-quality sound and refined aesthetics.
