The principle is simple and highly effective: combining a bass\/midrange speaker and a high-frequency driver on the same axis to approach a \"point source\" dispersion. The result: a more uniform response, better blending of registers, and more controlled directivity in reduced speaker formats.\u003c\/p\u003e\u003cp\u003eThis type of configuration is particularly appreciated when a precise rendering is sought in compact enclosures, without multiplying drivers or complicating phase alignment between channels.\u003c\/p\u003e\u003ch3\u003eWho Is the B\u0026amp;C 8 FCX 51 For?\u003c\/h3\u003e\u003cp\u003eThis 8-inch coaxial speaker is intended for manufacturers, integrators, and DIY audio enthusiasts who want to build or repair a professional-level compact sound reinforcement speaker. It is very suitable for projects where midrange clarity, presence of highs, and consistent coverage are priorities: stage monitors, small front speakers, auxiliary systems, nearfield speakers for live performances, or fixed installations in bars, clubs, multipurpose rooms, and places of worship.\u003c\/p\u003e\u003cp\u003eThanks to its high sensitivity (especially in HF) and its declared 100-degree coverage, it facilitates achieving clear and projected sound, even when the speaker must remain discreet in size.\u003c\/p\u003e\u003ch3\u003eCoaxial Design: Precision, Coherence, and Controlled Coverage\u003c\/h3\u003e\u003ch4\u003eThe Key Benefit of Coaxial: Soundstage Coherence\u003c\/h4\u003e\u003cp\u003eBy placing the HF section at the center of the LF speaker, the 8 FCX 51 promotes a natural transition between registers. This architecture helps maintain a stable perception of voices and instruments, with more precise localization and better homogeneity when moving in front of the system. It is a tangible advantage for monitors and compact speakers, where one wants to avoid the \"holes\" in coverage typical of some multi-driver configurations.\u003c\/p\u003e\u003ch4\u003e1.7-inch HF Motorization and High Efficiency\u003c\/h4\u003e\u003cp\u003eThe high-frequency section is based on a 1.7-inch (44 mm) HF voice coil and a polyamide diaphragm. With a declared HF sensitivity of 104 dB (1w\/1m), this coaxial is designed to deliver present and detailed highs while maintaining good dynamic headroom in an 8-inch format. The separate 8 + 8 ohms impedance (LF + HF) allows handling both channels according to the speaker architecture (appropriate crossover required).\u003c\/p\u003e\u003ch4\u003eBass\/Midrange: Mechanical Endurance and Reliable Operation\u003c\/h4\u003e\u003cp\u003eThe LF section uses a 2-inch (51 mm) copper wire voice coil, combined with a dual-roll suspension. The Xmax excursion of 6.5 mm and resonance frequency Fs of 69 Hz orient this model towards efficient compact enclosures, with a response that favors impact and cleanliness in the lower midrange. The exponential cone with waterproof treatment on the front adds extra resistance to usage constraints (transport, ambient humidity, stage conditions).\u003c\/p\u003e\n\n\u003ch2\u003eTechnical specifications\u003c\/h2\u003e\n\u003cdiv style=\"display:flex;flex-wrap:wrap;gap:2rem\"\u003e\n\u003ctable style=\"flex:1 1 300px;width:100%\"\u003e\n  \u003ctr\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eRackable\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left\"\u003eNo\u003c\/td\u003e\u003c\/tr\u003e\n  \u003ctr\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eCategory\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left\"\u003esound reinforcement accessory\u003c\/td\u003e\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ctable style=\"flex:1 1 300px;width:100%\"\u003e\n  \u003ctr\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eType\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left\"\u003eSpeakers\u003c\/td\u003e\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display:flex;flex-wrap:wrap;gap:2rem\"\u003e\n\u003cdiv style=\"flex:1 1 300px\"\u003e\n\u003ctable style=\"width:100%\"\u003e\n  \u003ctr\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eModel\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left\"\u003eB\u0026amp;C 8 FCX 51\u003c\/td\u003e\u003c\/tr\u003e\n  \u003ctr\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eNominal diameter\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left\"\u003e8 inches (21 cm) + HF 1.7 inches\u003c\/td\u003e\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ctable style=\"width:100%\"\u003e\n  \u003ctr\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003ePower (AES)\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left\"\u003e250 W (LF) + 50 W (HF)\u003c\/td\u003e\u003c\/tr\u003e\n  \u003ctr\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eNominal impedance\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left\"\u003e8 ohms (LF) + 8 ohms (HF)\u003c\/td\u003e\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ctable style=\"width:100%\"\u003e\n  \u003ctr\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eLF sensitivity\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left\"\u003e96 dB (1w\/1m)\u003c\/td\u003e\u003c\/tr\u003e\n  \u003ctr\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eHF sensitivity\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left\"\u003e104 dB (1w\/1m)\u003c\/td\u003e\u003c\/tr\u003e\n  \u003ctr\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eFrequency response\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left\"\u003e70 Hz -
