What amplifier power is required for the ESL Home (MK II)?
The ESL Home requires about 60 watts of power to reach 94 dB SPL at its rated impedance; higher power levels provide greater dynamic range, especially in the low frequencies.
What does the impedance curve of the ESL Home look like?
The nominal impedance is 4 Ω, dropping to about 3 Ω at high frequencies and peaking at approximately 13.5 Ω at lower frequencies.
What is the best way to position and space the ESL Home?
Ideally, the speakers should be placed 60–80 cm away from the head, with each panel at ear level and precisely angled; positioning them against the back wall or in a corner enhances the bass.
Can the ESL Home be used with a subwoofer?
No, the ESL Home is designed as a full-range electrostatic dipole; a subwoofer is neither included nor recommended.
What connections are available for the amplifier and power supply?
There are two connection panels: one for the amplifier (speaker terminals) and one for the power supply; unused connections are covered.
Is control via an app or DSP possible?
No, there is no built-in DSP or app functionality; adjustment is done mechanically (panel height and angle) and acoustically through positioning.
Is the ESL Home suitable for use in larger listening rooms or with multiple listeners?
No, it is a personal speaker: designed for a single listener, and positioning it for multiple listening spots results in a significantly reduced stereo experience.
What is the frequency response, and how is the bass reproduction?
The lower frequency limit (−3 dB) is around 40 Hz in free-standing configuration; low-frequency response is partially achieved by placing the speaker near a wall, and the electromagnetic load has been limited in terms of distortion.
Is the ESL Home compatible with tube amplifiers?
Yes, tube amplifiers are suitable, provided they have sufficient power output and can handle low impedances; the ESL Home is always designed with a 4-ohm load in mind.
How are the bass and treble controls adjusted?
The height is adjustable at the base via a mast; the angle is hinged and features a scale with a pointer for symmetrical left- and right-side adjustment.
