Very good experience, all the team are very knowledgeable and helpful.

The System

Listening with

Bowers & Wilkins 706 S3 · Speakers: passive 2-way standmount (25 mm Decoupled Carbon Dome, 6.5 in Continuum cone, Flowport)

Impedance: 8 Ω (minimum 3.7 Ω)
Sensitivity: 88 dB (2.83 V / 1 m, on axis)
Frequency response: 50 Hz – 28 kHz (response); 45 Hz – 33 kHz (range)
Recommended amplifier power: 30 – 120 (into 8 Ω, unclipped programme)
Other: max recommended cable impedance 0.1 Ω; 8.4 kg

Matching notes: The 706 S3 is rated at 88 dB (2.83 V / 1 m) into 8 Ω nominal (3.7 Ω minimum). Burson rates the Timekeeper 3X GT at 110 W into 8 Ω and 180 W into 4 Ω. At that rating the speaker would reach about 108 dB SPL at 1 m (calc., one speaker, before room gain). Bowers & Wilkins recommends 30 – 120 (into 8 Ω, unclipped programme) amplifiers. ^{[1] [2] [3] [4]}
