I am thoroughly impressed with my experience with Burson Audio. Their products are nothing short of exceptional—clearly crafted with attention to detail, performance, and quality. Equally impressive is their customer service, which was responsive, knowledgeable, and genuinely helpful throughout the entire process. From placing my order to receiving the delivery, everything was handled with remarkable efficiency and care. The entire transaction was smooth and seamless, leaving me more than satisfied.

The System

Listening with

Revel F226BE · Speakers: passive 3-way floorstander (1 in beryllium dome, 5.25 in midrange, 2x 6.5 in DCC woofers)
  • Impedance: 8 Ω
  • Sensitivity: 90 dB (2.83 V / 1 m)
  • Frequency response: 44 Hz – 40 kHz (-6 dB)
  • Recommended amplifier power: 50 – 200 W
  • Other: LF extension 38 Hz (-10 dB), 50 Hz (-3 dB); crossover 260 Hz / 2.1 kHz; 26.4 kg

Matching notes: The F226BE is rated at 90 dB (2.83 V / 1 m) into 8 Ω nominal. Burson rates the Timekeeper GT4 at 100 W into 8 Ω and 200 W into 4 Ω. At that rating the speaker would reach about 110 dB SPL at 1 m (calc., one speaker, before room gain). Revel recommends 50 – 200 W amplifiers. [1] [2] [3] [4]
