Напольная акустика — PMC fact.8 signature

The fact.8 signature is a passive floorstanding speaker with two-way driver layout made by the British company PMC, known for its Advanced Transmission Line bass loading, abbreviated ATL. It belongs to the signature edition of the fact range and uses several components taken from the fact fenestria. It arrived in early 2020 at USD 12,000 per pair, and a later US list figure stands at USD 15,999 per pair. Buyers can choose among three finishes - White Silk, Walnut and Metallic Graphite.

Key specs that matter

Two 140 mm (5.5 inch) natural fibre bass drivers, designed specifically for this model, work with a 19 mm (0.75 inch) Sonomex soft dome tweeter made by SEAS and cooled by ferrofluid. The crossover hands over at 1.7 kHz with slopes of 24 dB per octave. PMC quotes a frequency range of 28 Hz to 30 kHz, a nominal impedance of 8 ohm and a sensitivity of 89 dB at 1 W and 1 m. Recommended amplifier power runs from 15 W to 200 W. Each cabinet measures 1030 mm in height, 155 mm in width and 380 mm in depth, and weighs 20 kg.

Engineering and use context

Both bass units are loaded by a folded ATL path whose effective length is quoted as 3 m, and this line takes the place of a conventional reflex port or sealed enclosure. The pair of bass cones shares the low range below the handover point, and above it the soft dome takes over alone. The crossover network is fitted with Mundorf MResist Supreme resistors of non-inductive type and British-built ClarityCap capacitors, parts that PMC names among the items carried over from the fact fenestria programme. PMC positions the fact.8 signature for medium and larger rooms. The signature changes as a whole come from the research carried out for the fenestria, whose own cabinet adds an aerodynamically shaped Laminair port. PMC also sells a crossover upgrade kit for owners of the earlier fact.8, which brings that version closer to the signature specification.

Pairing

The fairly high sensitivity and the steady nominal load make amplifier choice easy. Even modest integrated amplifiers can drive the fact.8 signature, while the upper power rating also allows larger stereo power amplifiers.

Alternatives

The PMC fact.12 signature is its bigger sibling in the signature edition, a floorstander with a three-way driver layout.
