Scan-Speak Classic 18W/8542-10 Midwoofer

The Scan-Speak Classic 18W/8542-10 7" Midwoofer is a premium driver engineered for audiophiles and loudspeaker designers who demand accurate, controlled midbass reproduction. As part of Scan-Speak's revered Classic series, this unit combines meticulous craftsmanship with proven acoustic engineering, making it an ideal choice for high-fidelity two-way or multi-way speaker systems where clarity and definition in the lower midrange and upper bass are paramount.

This versatile midwoofer excels in a variety of applications, from compact bookshelf speakers to dedicated midbass modules in larger floorstanding designs. Its linear frequency response and low distortion characteristics ensure that vocals, instruments, and percussive elements are rendered with exceptional realism and punch, whether used in a home stereo, studio monitor, or high-end home cinema setup. The driver's 8-ohm impedance and 88 dB sensitivity (2.83V/1m) facilitate straightforward integration with most amplifiers.

Technically, the 18W/8542-10 features a 42 mm voice coil and a 6.5 mm linear excursion (Xmax), enabling robust dynamic performance. Its low total Q factor (Qts 0.35) and resonance frequency (Fs 43 Hz) support tight, well-damped bass response in sealed or ported enclosures. The low voice coil inductance (Le 0.2 mH) and carefully optimised motor system contribute to minimal phase shift and excellent transient response. With a maximum power handling of 130 watts and a 177.8 mm nominal diameter, this driver delivers authoritative, articulate midbass that elevates any loudspeaker design.
