F703SP

10" IsoFlare floorstanding speaker — UK-crafted F700SP Series flagship. The F703SP is the Special Production version of the F703, featuring a 10-inch IsoFlare point-source driver paired with a 10-inch multi-fiber bass driver in a 2.5-way BassTrax ported floorstanding cabinet. SP enhancements include Claritycap capacitors, Neotech PC-OCC wiring, gold-plated WBT terminals, cryogenic treatment, and an F1-grade machined aluminium plinth with integrated spikes.

Technical background

The F703SP uses a 250mm IsoFlare driver — the 10-inch coaxial that also powers the F1-10S — with a 3-inch titanium dome tweeter for HF extension beyond 26kHz. The SP crossover features ClarityCap capacitors, Neotech wiring, and cryogenically treated WBT terminals. Sensitivity of 94dB makes it an ideal valve amplifier partner.

Design story

The F703SP was designed for listeners who need the scale and efficiency of the 250mm IsoFlare driver without stepping into the F1 Series price range. Its heavyweight aluminium plinth eliminates cabinet resonance and provides a stable mechanical reference for the bass loading system.
