What customers say
The Martin Logan Aerius is celebrated as an outstanding entry into electrostatic loudspeakers, praised for its unparalleled transparency and clarity. Listeners consistently note the expansive soundstage and pinpoint accurate imaging. Vocals and acoustic instruments sound remarkably lifelike due to the detailed, natural presentation of the mid and high frequencies. The core theme revolves around exceptional sonic performance that belies its size. However, achieving this performance requires careful consideration. Users emphasize the need for high quality, high current amplification to drive these speakers effectively. While the bass is tight, some users find the low end benefits significantly from pairing with a dedicated subwoofer for full range impact. Overall, the Aerius offers beloved high fidelity quality.
Know before you buy
The Aerius has a sensitivity of 89 dB and an impedance of 4 ohms. While they are compatible with amplifiers rated for 4, 6, or 8 ohms, they perform best with a high-quality amplifier capable of delivering between 20 and 400 watts per channel to maintain control over the electrostatic panels.
The Aerius uses a hybrid design, pairing a dedicated 8-inch sealed woofer for the low end with an electrostatic panel for the mids and highs. This setup provides a tight, accurate bass response that integrates seamlessly with the transparency of the electrostatic transducer.
Because they utilize electrostatic panels, the Aerius speakers are dipole radiators, meaning they emit sound from both the front and back. You will get the best soundstage and clarity by placing them a few feet away from the front wall to allow the back wave to dissipate properly.
While the Aerius is highly regarded for its musical transparency and detail, it works excellently in a home theater system as well. Their expansive soundstage and low listening fatigue make them particularly effective for long movie sessions.
CLS stands for Curvilinear Line Source. This technology gives the electrostatic panel a slight horizontal curve, which helps disperse high-frequency sound more effectively across your listening area without sacrificing the clarity typical of flat panels.
Yes, the dual-wired 5-way binding posts are designed to support bi-wiring, which allows you to run separate cables to the woofer and the electrostatic panel sections. This can offer a slight improvement in signal clarity and separation.
