The Visaton FRS 8 - 4 Full-range Woofer is a compact broadband driver designed to deliver clear, natural sound across a wide frequency spectrum. As a versatile full-range unit, it excels in applications where space is limited but audio quality cannot be compromised. Ideal for use in small bookshelf speakers, multimedia systems, or custom DIY audio projects, this woofer provides a balanced and coherent soundstage without the need for a separate tweeter in many setups. Its paper cone membrane ensures a warm, organic tonal character that audiophiles appreciate, making it suitable for both music and speech reproduction.

Technically, the FRS 8 - 4 features a nominal diameter of 76.2 mm and a DC resistance of 3.5 ohms. With a sensitivity of 82 dB SPL at 1 metre for 2.83 V, it is efficient for its size. The total Q factor (Qts) of 0.69, combined with a mechanical Q (Qms) of 3.61 and an electromagnetic Q (Qes) of 0.85, indicates a well-damped driver suitable for sealed or vented enclosures. The maximum linear excursion (Xmax) is 0.25 mm, and the voice coil inductance (Le) is 0.4 mH. For sealed enclosures, a volume of 3 litres yields a -3 dB cutoff frequency of 133 Hz, while a vented design requires 3.4 litres. The cutout diameter is 71.1 mm, and overall dimensions are 78 mm. This Visaton driver offers a reliable, high-quality solution for achieving full-range audio in compact designs.
