Know before you buy
Yes, these speakers are designed to integrate seamlessly with any electrostatic loudspeaker system. They are compatible with 4, 6, or 8 Ohm amplifiers and handle between 20 and 300 watts per channel.
The speakers measure 48.8 inches tall and 9.4 inches wide. Because they feature a slim 6.5-inch depth and include a pivoting wall bracket, they are designed to fit discreetly in most home theater environments.
Yes, they require a low-voltage DC power supply to energize the electrostatic transducer. The power draw is minimal, consuming a maximum of 2 watts per speaker during operation and less than 1 watt in standby.
The pivoting bracket allows you to angle the speaker toward your primary listening position. This is essential for electrostatic speakers, as it helps you precisely focus the soundstage for a more immersive surround experience.
While the 6.5-inch high-excursion woofer and bass reflex port provide robust low-frequency handling, they have a frequency response floor of 68 Hz. For a full-range home theater experience, pairing these with a dedicated subwoofer is recommended to handle the deepest bass frequencies.
The XStat CLS electrostatic transducer provides exceptional clarity and detail in the high and mid frequencies. Because it acts as a line source, it offers a unique, expansive soundstage that is often more transparent and dynamic than traditional cone-based drivers.
