Scan-Speak Discovery 15W/8424G00 5.5" Woofer

The Scan-Speak Discovery 15W/8424G00 is a 5.5-inch woofer engineered to deliver precise and articulate mid-bass performance, making it an ideal choice for discerning audio enthusiasts and custom loudspeaker builders. As part of the renowned Discovery series, this driver excels in applications where accurate sound reproduction is paramount, whether in a two-way bookshelf design, a dedicated mid-bass module, or a high-fidelity home theatre system. Its compact form factor allows for versatile integration into enclosures where space is at a premium, without compromising on sonic integrity.

Technically, this woofer boasts a low total Q factor (Qts) of 0.25, ensuring tight, controlled bass response with excellent transient behaviour. The combination of a mechanical Q (Qms) of 3.6 and an electromagnetic Q (Qes) of 0.27 contributes to its efficient damping and linear performance. With a sensitivity of 87.7 dB (SPL at 1m/2.83V) and an impedance of 8 ohms, it pairs well with a variety of amplifiers. The 24.89 mm voice coil and 5.5 ohm DC resistance (Re) support a maximum power handling of 12 watts, while the resonance frequency (Fs) of 46 Hz and equivalent volume (Vas) of 14.44 litres provide clear parameters for enclosure design. This driver represents a refined choice for those seeking authentic, uncoloured mid-bass reproduction.
