Напольная акустика — PMC prophecy7

The prophecy7 is a three-way passive floorstander from the British company PMC and occupies the central position of the prophecy series, which was announced in December 2024 with shipments from 1 February 2025. The range has five members - the prophecy1 standmount at GBP 2,875, the slim two-way prophecy5 tower at GBP 4,575, the prophecy7, the larger prophecy9 and the prophecyC centre channel. UK pricing for the prophecy7 is GBP 6,575 and the euro price is EUR 7,995, while the US recommended figure is USD 9,499 per pair.

Key specs that matter

A long-throw 125 mm (5 inch) bass driver with a light, mica-filled cone covers the low range, a 55 mm soft dome midrange handles the middle band, and a 26 mm soft dome tweeter with ferrofluid cooling sits at the top. The hand-built crossover divides the signal at 600 Hz and 3.1 kHz. PMC rates the response at 40 Hz to 20 kHz within 3 dB, the sensitivity at 88 dB for 1 W at 1 m and the nominal impedance at 6 ohm, and recommends amplifiers of 25 W to 250 W. The cabinet is 965 mm high, 165 mm wide and 310 mm deep, and each speaker weighs 23.7 kg.

Engineering and use context

The midrange dome is mounted in a waveguide used only in the prophecy series and has an n-compass sculptured profile, a detail taken from PMC studio monitors. The tweeter sits behind a dispersion grille that PMC says controls directivity across up to 180 degrees. Bass loading combines the Advanced Transmission Line principle with the company's Advanced Bass Technology and a redesigned, patent-pending vent called LaminairX. PMC states that this vent shape negates turbulence and so cuts both resistance and harmonic distortion by as much as 3 dB. This vent is integrated into a weighty extruded aluminium base, which doubles as the anchor for the cabinet. Veneers are sustainably sourced and finished with minimally invasive techniques in Walnut, Mediterranean Oak or Black, and magnetic grilles carry an open-weave textured fabric.

Pairing

Amplifier matching starts from the sensitivity and the nominal load, and the power recommendation covers both integrated amplifiers of moderate output and larger stereo power amplifiers. The prophecyC centre from the same series lets a pair of prophecy7 towers handle the main left and right duties when a film system is built around them.

Alternatives

The PMC prophecy9 is the larger floorstanding model above it in the prophecy series, priced at GBP 8,975 in the UK.
