Scan-Speak Ellipticor 18WE/8542T00 Mid-range Woofer

The Scan-Speak Ellipticor 18WE/8542T00 Mid-range Woofer represents a pinnacle of engineering for discerning audio enthusiasts who demand nothing less than reference-grade sound reproduction. Designed to serve as the critical mid-band link in high-fidelity loudspeaker systems, this driver excels in delivering vocals and instruments with breathtaking realism and transparency. Its exceptional build quality makes it equally suited for use in two-way designs as a dedicated mid-range, or as part of a multi-way configuration where precise crossover integration is paramount.

At the heart of this driver lies a suite of advanced technical features. The voice coil inductance is remarkably low at just 0.14 mH, ensuring extended high-frequency response and minimal phase shift. With a total Q factor (Qts) of 0.32 and a mechanical Q (Qms) of 5.01, the 18WE/8542T00 offers tightly controlled bass behaviour and excellent transient response. The generous 7.7 mm of linear excursion (Xmax) allows for impressive dynamic range, while the 89 dB sensitivity (SPL 1m/2.83V) ensures efficient power handling. The 8-ohm impedance and 6-ohm DC resistance facilitate straightforward system integration.

This Ellipticor series driver combines a 152.4 mm nominal diameter with a robust 18 mm frame depth, requiring a 158 mm cut-out and a 4.5 mm mounting hole diameter for its six fixing points. The result is a mid-range woofer that delivers pristine, uncoloured sound with exceptional detail and control, making it an ideal choice for the most demanding audio applications.
