Leak Sandwich 2060
Documentation on the Leak Sandwich 2060 is thin and scattered. It comes mostly from forum impressions, classified listings and the occasional show demo. What the record does show is a three-way floorstander from H.J. Leak & Co. Ltd., built roughly between 1975 and 1978. It still turns up working at hi-fi events. It was demonstrated at The Maverick 2024 HiFi Show alongside a Marantz CD6007 and Hegel HD10, and owners regularly pair theirs with period Leak electronics.
The name comes from Leak's "Sandwich" cone technology - an aluminium/polystyrene/aluminium laminate praised for rigidity and damping, and described in period-adjacent sources as pioneering driver tech. A Russian forum poster goes further, calling it "probably the first acoustic system made of composite materials." The bass driver is a 12-inch sandwich-cone unit, and the cabinet is a three-way design. One UK dealer describes the drivers as "unique Leak aluminium foil and expanded polystyrene 'sandwich'" woofers. Rated at 18 watts with 4-8 ohm impedance. Some Russian listings suggest an 8-ohm figure for the 2060 specifically. They also note a separate modified "LEAK SANDWICH 15 ohm" variant sold only alongside the 2060, with both pairs connectable in parallel.
Owner impressions are consistent. The 2060 is described as "very musical and soulful," with a natural, breathing quality in the vocal range - a huge plus, as one listener put it. It "works beautifully with both tube and transistor amplifiers." It has limits, though. Fast, aggressive material can muddy the lower range and cost detail, and heavy metal is reportedly not its forte. One owner compared them to JBL 4312 monitors - "different, like Paul McCartney and Hayao Miyazaki" - with the JBL more honest, the Leak more for gourmet listeners. A 1975 classified in Hi-Fi News (September 1975, p.?) listed a complete Leak system - 2200 amplifier, 2001 turntable with Shure cartridge, and two 2060 loudspeakers - at £585.07, or £450.46 for the bundle.
No dimensions, crossover points, frequency response, or original standalone price have surfaced. A seller on pink fish media reported replacement tweeters that "don't sound too good," suggesting originals are hard to come by. The "2060" designation itself remains unexplained, and the relationship to the better-documented Sandwich 200 and 250 is not established in available sources.
