Built in Scotland, the SP edition uses the F702's high-quality 200mm IsoFlare™ driver and 200mm woofer/midrange with rigid multi-fibre cone and FyneFlute™ speaker surround. The IsoFlare™'s 25mm magnesium compression tweeter features a unique RF waveguide pole piece that provides an incredibly smooth, full frequency response and superb music reproduction. The F502SP also benefits from advanced crossover components from the F700s and the aluminium sandwich plinth with BassTrax™ Tractrix profile bass diffuser, which is specifically designed to precisely match the F502SP's more compact cabinet. The SP is available in high gloss black and high gloss white with diamond machine finish on the aluminium speaker chassis.
