What customers say
The MartinLogan Quest is widely regarded as a high-end audio benchmark, celebrated for its electrostatic transparency and detail. Owners consistently praise the speaker's ability to generate a vast, holographic soundstage with precise imaging and a natural midrange. The core theme revolves around its unparalleled sonic experience for dedicated listeners. However, achieving this performance demands careful system matching. Users emphasize that the Quests require robust, high-current amplifiers to manage the impedance effectively. Furthermore, optimal sound quality is highly dependent on meticulous room placement adjustments. While this setup process can challenge casual users, the resulting audio quality offers exceptional value compared to newer models, provided one accepts the potential need for future panel refurbishment.
Know before you buy
These speakers are compatible with amplifiers ranging from 20 to 400 watts per channel. Because they have a minimum impedance of 1.5 Ohms, you should ensure your amplifier is stable and capable of handling low-impedance loads to get the best performance.
The adjustable bass and presence contour controls allow you to fine-tune the speaker's output to match your room's acoustics. This helps you balance the low-end response and high-frequency detail based on your specific listening environment.
Each speaker stands 72.75 inches tall and 19 inches wide, so they require a significant amount of floor space and vertical clearance. Given their size and electrostatic design, they perform best when placed away from side walls to allow the soundstage to develop properly.
The large 48-inch transducer provides an expansive, highly detailed soundstage that reproduces high frequencies with exceptional clarity. This technology minimizes distortion, allowing for a more realistic and nuanced listening experience compared to traditional cone drivers.
Yes, the integrated 12-inch woofer is designed to handle the low-frequency range, providing a frequency response down to 28 Hz. This allows the speakers to deliver robust, full-range sound without necessarily requiring an external subwoofer.
At 115 pounds each, these speakers are heavy and require careful placement to achieve the optimal soundstage. Once positioned, the primary setup involves connecting them to a capable amplifier and adjusting the contour controls to suit your room's unique characteristics.
