Напольная акустика — Magnepan LRS+

The LRS+ is a compact planar-magnetic floorstanding loudspeaker from Magnepan, built as the brand's entry-level ribbon-panel design. Magnepan has built its entire reputation on planar-magnetic panel speakers since the 1960s, and the LRS+ represents the current, most accessible entry point into that distinctive technology within the brand's catalogue.

Key specs that matter

Rated response is 50 Hz to 20 kHz. Sensitivity is 86 dB into 4 ohms, a moderate figure typical of planar-magnetic designs, which generally trade some efficiency for the speed and openness the technology is prized for. The listed weight figure of 121.9 x 33.02 x 2.54 appears to actually describe the panel's dimensions rather than its mass, an easy mix-up given how thin Magnepan's panels are - at just 2.54 cm deep, this is an exceptionally slim design compared with any conventional box speaker.

Sound and use context

Expect the fast, open character typical of Magnepan's planar-magnetic panel technology, with a wide dispersion pattern rather than a conventional point-source presentation - this is a different listening experience from a conventional box speaker, often described as more like being present in the recording space than listening to a reproduction of it.

Pairing

The 86 dB sensitivity and 4 ohm load call for an amplifier with reasonable current delivery rather than a very low-power design, since planar-magnetic panels, despite their thin profile, are not generally forgiving of underpowered amplification.

Alternatives

Magnepan's numbered .7 and 1.7i models sit above this model in the brand's planar range for a larger panel and deeper bass extension, worth considering if the LRS+'s entry-level scale leaves something to be desired in bass reach. Because planar-magnetic panels radiate from both front and rear surfaces equally, placement well away from the rear wall matters considerably more with this design than with a conventional forward-firing box speaker, and Magnepan typically recommends a metre or more of clearance behind the panel for best results. First-time planar-magnetic owners should also budget time for careful toe-in adjustment, since these panels can be considerably more placement-sensitive than a conventional point-source design. A dealer demonstration in a room with genuine rear clearance is the only reliable way to judge how this panel will actually perform once installed at home.
