Floorstanding loudspeakers — German Physiks PQS-100

The PQS-100 is a compact floorstanding loudspeaker from German Physiks, sharing the brand's distinctive omnidirectional bending-wave driver in a considerably smaller cabinet than the larger HRS-130. German Physiks built its entire catalogue around this one unconventional driver principle, radiating sound outward in essentially all directions rather than focusing it forward the way a conventional cone or dome driver does, and the PQS-100 represents the most accessible way into that technology.

Position in line

It sits below the Unicorn MK II and PQS-302 in German Physiks' floorstanding hierarchy, as the brand's most compact current model. Compared with the larger HRS-130, the PQS-100 trades cabinet volume and low-frequency reach for a manageable footprint, making the brand's unusual driver technology accessible to a smaller room than the company's flagship towers would suit.

Key specs that matter

Rated response is 120 Hz to 24 kHz, a narrower low-end figure reflecting the compact cabinet - this narrow window is a direct consequence of the small enclosure rather than a limitation of the driver technology itself, and points strongly toward pairing with a subwoofer for anything below the midrange. Sensitivity is 84 dB into 4 ohms with a 4-40 W window, a modest power requirement despite the moderate sensitivity figure. At 26.7 x 27.5 x 31.2 cm and 11 kg it is a compact tower, likely intended as a satellite in a system built around a companion subwoofer given how narrow the rated bandwidth runs.

Sound and use context

Expect the same wide, omnidirectional dispersion character as the larger HRS-130, in a compact cabinet that leaves deep bass to a companion subwoofer - the spatial presentation this bending-wave technology creates is distinctive, often described as less fatiguing over long listening sessions precisely because it does not depend on a narrow, precisely aimed sweet spot the way conventional speakers do.

Pairing

The 4-40 W window admits low-power tube amplifiers as readily as modest solid-state designs; a subwoofer is recommended given the narrow bass extension, and matching its crossover point carefully to this speaker's rated 120 Hz low end is worth doing with care.

Alternatives

The HRS-130 sits above this model in German Physiks' range with fuller bass extension from a larger cabinet, worth the step up if a subwoofer is not part of the plan and genuine full-range performance from the main speakers alone matters more than a compact footprint.
