Bi-wiring Although Spendor does not specifically recommend bi-wiring, the facility is available on some of our products. Bi-wiring may improve sound quality by separating the current paths for Low (LF) and High (HF) frequencies. Make the connections as shown below (Fig 3) only the left channel connection is shown. Store the terminal links safely. Generally speaking, for a given budget for cables, the best sound quality will usually be obtained by using a single set of cables rather than two sets of cables (biwired) at half the cost.

Bi-amping Although Spendor does not specifically recommend bi-amping, the facility is available on some of our products. Bi-amping allows two independent audio power amplifier of equal or similar quality to be used for LF and HF signals. The benefits of bi-amping may include reduced intermodulation distortion because the low and high frequency signals are amplified independently, and more power reserve and dynamic range because each amplifier has less ‘work’ to do than a corresponding single amplifier. For bi-amping make the connections as shown below (Fig 4), only the left channel connection is shown. Terminal links MUST be removed before bi-amping. Store the terminal links safely.

Cable Quality Loudspeaker cables can have an important effect on sound quality. Choose good quality low resistance cables with high purity metal conductors and low-loss dielectric (insulation). Ask your dealer for advice on cables to suit your system and budget.

Caring for your Loudspeakers Spendor’s real wood veneers and solid timber elements should be treated like high quality furniture. Routine dusting with a soft cloth is recommended. Do not apply any aerosol spray directly as this could damage the drive units or grille fabric. Dust on the grille cloth can be removed with a sticky roller or a piece of sticky tape or by gentle vacuuming with a soft brush adaptor. Do not expose the cabinets to damp, widely fluctuating temperatures or direct sunlight, appearance and performance may suffer. Spendor cabinets are finished in natural wood, over time the wood will age and mature, evening out and often darkening the surface colour while highlighting the natural grain and patina.
Queries and Service If you require advice or service on your audio system please contact your Spendor dealer. We recommend that you retain all the packaging for your loudspeakers in case you need to transport them safely in the future.
