Wharfedale Mach 9 (c. 1983)
Little is documented about the Wharfedale Mach 9. There are no brochure scans and no service literature, and the VTA's files hold a single period review. What the record shows is that it was a large floor-standing loudspeaker, sold at $755 each, in a particle-board enclosure finished in walnut veneer. High Fidelity (November 1983, p.38) gave the front dimensions as 13¾ by 32½ inches, with the cabinet 13¾ inches deep. It also noted a limited five-year warranty on parts and labor.
The same review found the Mach 9's response held within ±4¼ dB from 50 Hz to 16 kHz. Total harmonic distortion averaged under half a percent from 50 Hz up. That is about all the verifiable record there is: a serious, fairly expensive early-1980s Wharfedale floorstander that the mainstream catalogs barely acknowledged.
