The aesthetic appeal, often described as striking and elegant, also contributes positively to the overall sentiment, making the Ethos not just an audio component but a statement piece. Overall, the MartinLogan Ethos is celebrated as a pinnacle of audio engineering, consistently exceeding the expectations of discerning listeners.
Know before you buy
The Ethos uses a thin, transparent electrostatic panel for mid and high frequencies, which provides exceptional clarity and detail. It then pairs this with a dedicated 200W powered woofer to handle the low-end, giving you the speed of an electrostatic speaker with the deep bass punch of a traditional design.
Yes, you will still need an external amplifier to drive the electrostatic panels. However, because the speakers have a built-in 200W amplifier for the bass section, your external amplifier can focus its power on the mid and high frequencies, making the speakers easier to drive than many high-end alternatives.
Yes, because the electrostatic panels have a controlled 30-degree horizontal dispersion, they are more directional than standard speakers. This design helps minimize unwanted reflections off your side walls, but it does mean you should spend some time angling them toward your primary listening position for the best soundstage.
Yes, the Ethos is compatible with amplifiers rated for 4, 6, or 8 ohms. While the impedance drops at higher frequencies, the built-in powered woofer reduces the overall load on your receiver, allowing it to perform efficiently with a wide range of equipment.
The Vojtko DSP engine manages the integration between the electrostatic panel and the powered woofer. It ensures a seamless transition at the 375 Hz crossover point, resulting in a balanced, coherent sound that prevents the bass from feeling disconnected from the rest of the frequency range.
Each speaker stands roughly 44 inches tall and features a slim, elegant profile that fits well in most living rooms. Because they are floor-standing and rely on rear-firing passive radiators for bass, it is best to leave a little breathing room between the back of the speaker and the wall to ensure optimal low-frequency performance.
