Naim SBL Floorstanding Speakers – Black Ash (1987)

A fine pair of the legendary SBL Loudspeakers from British Hi-Fi experts Naim Audio. For their age (built in 1987 according to Naim serial numbers) they are in very good, fully working condition with a couple of minor blemishes and come in original factory packaging with our standard three month warranty.
Naim Say….
The loudspeaker, once believed to be the most important part of the system, is now relegated to its natural position at the very end of the chain. Its design remains as challenging as that of any other component. Converting electrical energy into acoustic energy is a task full of inherent conflicts to which the Separate Box Loudspeaker brings radically new solutions. The SBL is a two-way dynamic loudspeaker of the highest performance, genuinely designed to be driven by real amplifiers in real-life listening rooms, both easy to drive and is easy to site. Its integral stand, modest floor area and wide tolerance of room conditions suit it to many different environments. The loudspeaker is constructed out of three small, separate cabinets assembled onto an integral stand which is a vitally inter-related part of the design. Each drive unit is isolated in its own enclosure, with the third cabinet acting as an acoustic load for the mid-bass driver, providing the extended low frequency performance typical of a large cabinet loudspeaker without losing the rigidity and effective resonance control achievable in small loudspeakers.
The technology behind the SBL affords refined and accurate solutions to many complex problems. An advanced system of mass-dampers controls resonance at source in both drivers and cabinets. The tweeter is decoupled at all audio frequencies, effectively minimising modulation of high frequencies by vibrations generated by the mid-bass driver. The phase plug fitted to the bass unit provides for controlled leakage of air past the voice-coil, which stays correctly positioned regardless of varying conditions of temperature and pressure inside the cabinet. A special development is the unique high-precision acoustic resistance unit that couples the mid-bass and bass-loading cabinets. The external crossover is fixed onto the rear of the SBL and can be mounted or removed in a few minutes. This makes it possible to upgrade a system from passive to active operation without changing loudspeakers. Active systems offer great potential performance, but please bear in mind that this performance can only be realised if the system uses sources and amplification of the highest quality and has been well installed.
