Add 'w'… to Frontro and you have Mellow Acoustics' unique speaker [£7'500/pr] whose circular 12" top conceals a 600Hz-20kHz electrostatic driver crossed over to a small 5.25" dynamic woofer in the triangular section below. The electrostatic flat membrane divides into six concentric rings which, Quad style, are fed from a delay line center to edge. The lot slots into a frame just 76cm tall and 50cm wide. Sensitivity is a low 84dB, grill cloths come in gunmetal grey, burgundy or navy and a special screen beneath them protects the e-stat panel from dust and moisture. A figure-8 IEC provides power for the 2'000V polarizing voltage through two step-up transformers.
