Where many speakers at this price compromise on cabinet work or crossover quality, the F501SP uses cryo-treated Claritycap components and gold-plated WBT terminals throughout.\u003c\/p\u003e\n\n\u003ch2\u003eIsoFlare Point Source Driver\u003c\/h2\u003e\n\n\u003cp\u003eThe IsoFlare driver places a 25mm magnesium dome compression tweeter at the exact geometric centre of the bass\/midrange cone, so both drivers share the same acoustic origin. The result is a point source — no time-alignment errors between tweeter and mid\/bass, and a stable, coherent soundstage that holds its shape across a wide listening area. The 150mm multi-fibre bass\/midrange cone uses Fyne's FyneFlute roll surround, which reduces harmonic distortion at the surround junction compared to a conventional rubber roll.\u003c\/p\u003e\n\n\u003ch2\u003eBassTrax Tractrix Porting\u003c\/h2\u003e\n\n\u003cp\u003eThe BassTrax system fires bass energy downward through a Tractrix-profiled diffuser that sits at floor level. The Tractrix profile reduces port turbulence at high excursions, keeping bass clean and controlled rather than boomy. The F501SP uses a twin cavity loading system alongside the BassTrax port, extending bass response to 36Hz in-room while maintaining definition at low levels.\u003c\/p\u003e\n\n\u003ch2\u003eCrossover and Terminals\u003c\/h2\u003e\n\n\u003cp\u003eThe 2½-way crossover crosses the IsoFlare driver at 250Hz and 1.7kHz, with the lower bass cone running below 250Hz to extend low-frequency output and power handling. Crossover components are cryo-treated (Cryo-Lite process) to reduce dielectric and conductor noise. The rear panel carries gold-plated WBT Nextgen 0703 terminals with bi-wire capability, and HF energy and Presence trim switches allow ±3dB adjustment of treble character to suit room acoustics.\u003c\/p\u003e\n\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\n\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSystem type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e2½-way, downward-firing port, BassTrax Tractrix diffuser, twin cavity\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eIsoFlare driver\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e150mm multi-fibre cone, 25mm magnesium dome compression tweeter, neodymium magnet\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBass driver\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e150mm multi-fibre cone, FyneFlute surround\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eFrequency response\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e36Hz–34kHz (–6dB, typical in room)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSensitivity\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e91dB (2.83V @ 1m)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eImpedance\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e8Ω nominal\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCrossover frequencies\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e250Hz \u0026amp; 1.7kHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eRecommended amplifier power\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e30–180W RMS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eContinuous power handling\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e80W RMS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDimensions (H × W × D)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e984 × 288 × 320mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eWeight\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e21.0kg each\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\n\u003ch2\u003eWho Is It For?\u003c\/h2\u003e\n\n\u003cp\u003eThe F501SP suits listeners who want a full-range floorstanding speaker with genuine low-frequency extension in a slim cabinet. The 91dB sensitivity and 8Ω impedance make it an easy load for amplifiers from around 30 watts, so it works well with valve amplifiers as well as solid-state designs. The crossover adjustments are genuinely useful — if your room is bright, dropping the HF trim by 1.5dB makes a real difference without affecting the midrange. The F501SP competes with speakers significantly more expensive and would be our recommendation for anyone budgeting up to £4,000 for a pair of floorstanders.\u003c\/p\u003e\n\n\u003ch2\u003eBuying from Martins Hi-Fi\u003c\/h2\u003e\n\u003cp\u003eMartins Hi-Fi has been selling hi-fi since 1968.
