Сабвуферы — Wharfedale WH-D8

The WH-D8 is the smallest active subwoofer in Wharfedale's WH-D range, the entry point to the British brand's subwoofer lineup, with the WH-D10 and the SW models above it for larger spaces. Wharfedale designed it to bring deep bass to stereo and home cinema setups without dominating the room. The American list price was USD 449, and in Australia it was offered at AUD 699.99.

Key specs that matter

One 200 mm long-throw cone driver gets its drive from a class D amplifier rated at 70 W continuous output and 150 W quoted as peak. Frequency response is 40 Hz to 120 Hz within 3 dB, peak SPL at 1 m is 105 dB, and S/N reaches 86 dB or more. The box is 268 mm wide, 300 mm deep and 298 mm high, with a weight of 7.5 kg.

Engineering and use context

Wharfedale describes the enclosure as a vented box. The amplifier uses a balanced class D drive design. The woofer has a composite fibre cone. A low-pass filter adjusts continuously from 40 Hz to 150 Hz, the rear panel has a phase inversion switch, and a power sensor turns the unit on when signal arrives and back to standby when it stops. Line input sensitivity is 200 mV for maximum output. Finishes are black woodgrain or white pebble grain, each with a high-gloss lacquered front baffle, and in Australia the colours are sold as piano black and piano white.

Pairing

Two RCA phono sockets take a stereo line feed from a preamp or from the pre-outs of an integrated amp, with 20 kohm input impedance, and a separate RCA input handles the mono LFE output of an AV receiver. With its high upper crossover limit, the WH-D8 can support very small satellite or desktop speakers whose bass fades well above 100 Hz, while the lower settings suit larger bookshelf models.

Alternatives

The Wharfedale WH-D10 is the bigger subwoofer of this range, intended for listeners who want deeper bass and higher output.
