Gabriel’s Burson Funk with Audeze LCD-X and ELAC Uni-Fi Reference

• Impedance: 20 Ω
• Sensitivity: 103 dB/1mW (at Drum Reference Point) ≈ 120.0 dB/V (calc.)
• Frequency response: 10 Hz – 50 kHz
• Plugs / cables supplied: braided 4-pin XLR combo cable with 6.35 mm single-ended adapter
• Other: recommended power >250 mW (min >100 mW; max 5 W RMS); 106 mm driver; max SPL >130 dB

Matching notes: At 20 Ω and 103 dB/mW, the Audeze LCD-X is a low-impedance load, and an efficient one: about 0.32 V (5 mW, 16 mA) for 110 dB SPL (calc.). Burson does not publish a 20 Ω rating for the Funk. Its 16 Ω and 32 Ω ratings (3.5 W SE; 2.5 W SE) fall either side of it. The Funk’s under 2 Ω headphone output impedance is less than 1/10 of the load. ^{[1] [2] [3] [4]}

Specs from manufacturer data unless a source below says otherwise. “calc.” values are worked out from those figures (V = √(P × R); 110 dB SPL used as a loud reference level). Gear listed without specs is not in our spec library yet.
