Improving on the F502, the UK built SP edition uses the premium 200mm (8″) IsoFlareTM driver and 200mm (8″) bass/mid driver from the F702, featuring rigid multi-fibre cones and FyneFluteTM roll surrounds. The IsoFlare’s 25mm magnesium compression tweeter has a unique HF wave guide pole piece delivering an incredibly even, full-range frequency response and outstanding Hi-Fi musical imaging. The F502SP also benefits from the F700’s advanced crossover components and aluminium sandwich type plinth with BassTrax tractrix profile bass diffuser, re-engineered to precisely tune the F502SP’s more compact cabinet. The SP is available in high-gloss black and high gloss white as standard, or a luxurious deep gloss lacquered walnut veneer with a diamond machine cut finish on the aluminium driver
