When one of my Electromotion ESL power supplies failed, I bought 2 of the Mean Well adapters in the picture (output: 15 V, 800 mA) They are high quality medical spec power supplies, with only 80 mV of ripple and high (400k hours) MTFB. The cable is only 1,8 m (6 feet) long, shorter than the...

The Electromotion ESL original adapter (I have the European version) is marked G051T-150040B-1 (input: AC 100-240V, 50-60 Hz; output DC 15V, 0,4 A, center positive). Sometimes it is also referred to as G051T-150040-1 (without the B), which looks to be the same. It can easily be found on the...

Absolutely 100% agree. :bowdown:

Small adjustments...

Here are the frequency responses and the linear interpolations calculated with Wolfram Mathematica (red and green lines): both lines are -1.3 dB/octave. Sub 250 Hz range with Home Audio Fidelity convolution files (DRC); 1600 Hz - 20 kHz with slight (±3dB) 3-band parametric equalization (ROON eq...

Recently I realized how much those posts stink: playing a Reference Recording organ record (The Orchestral Organ - Jan Kraybill) they were rattling on low frequencies pedal notes! That took a lot of time to detect: in the first place I thought the rattling noise came from the panel (Oh my...!)...

Excellent guide for Electromotion ESL owners! :bowdown:

You're right about the effect of the panels on comb filtering. Here are the frequency responses without smoothing (1 kHz to 22 kHz), blue is with panels. :D

Here are my ML with Oudimmo Akupan panels (5 cm thickness, 60x120 cm - 2"x 23.6"x 47.2"). Distance Akupan panels - wall: 5 cm (2"). Distance electrostatic panels - front wall: 1 m (about 39"). The graphic shows the difference between before/after panels positioning (blue = with panels). The...

Hi, new to the forum me too, but now my EM ESLs have been playing for almost two years in my room. :-) I've had different DACs (TacT, Wadia, Teac, and now Matrix Audio), and tone-color differences are certainly present, but mere nouances compared to the overall importance of room+(room...

Martin Logan Electromotion ESL. Third-octave smoothing curve (in red) after Digital Room Correction, scale 5dB/div.; 4,5x4m room, mansard ceiling, carpet on the floor, fabric on back wall.

I have a pair of Electromotion ESL and I use Dirac room correction on a Windows 10 PC. The PC happens to be also the main source, since my music collection is in .flac format (plus a thousand of CDs on the shelves). I've been using room correction since 2004, when the only option was the TacT...
