Floorstanding loudspeakers — Børresen Acoustics Børresen Z2 Cryo Edition

The Børresen Z2 Cryo Edition is a floorstanding loudspeaker from Børresen Acoustics, sharing the Z2's core electrical specifications with the addition of the brand's 3-day deep cryogenic treatment at -196°C. The Børresen Z2 Cryo Edition brings Børresen's considered engineering to a Z-series floorstanding format with enhanced conductivity.

Key specs that matter

Rated response spans a wide 40Hz to 50,000Hz within plus-or-minus 3dB, matching the standard Z2. Sensitivity is 86dB into a demanding 4 ohm load, with recommended amplifier power above 50W. The 3-day cryogenic treatment increases conductivity by a meaningful 6-8%. At 102.5 x 22.5 x 40.0cm and 34.0kg, the Børresen Z2 Cryo Edition shares identical dimensions with the standard Z2, with electronic components either borrowed from the 0-series, redesigned, or resulting from extensive sound-research by-products.

Sound and use context

Expect the exceptionally fast, detailed character Børresen's celebrated ultra-low-impedance driver technology is broadly known for, enhanced by the cryogenic treatment's improved conductivity.

Pairing

The demanding 4 ohm impedance combined with the above-50W recommended power calls for a capable amplifier.

Alternatives

Børresen's own standard Z2 offers a more accessible alternative without cryogenic treatment within the same broader Z-series catalogue.
