Yes, that is the response of the speakers measured with the UMIK from miniDSP and the REW at listening position.

I think that DieterK would like to know the brand of the bass drivers used in your aforementioned dipole loudspeaker.

This is the listening position response (smoothened) of my Quad Esl-63 with sub, and as in juliopr:s graph, the upper limit is 180 dB and the lower is -240 dB.

The tower of power on the back is very nice !

Thank you! Those are not fans, but the side of heat sinks you are seeing. No fans on the amp at all

2 Eminence Alpha 15A for bass, 2 PRV Alto Series 8MR400A Midbass drivers and a Selenium D220Ti compression drivers in Dayton Audio 12" round Waveguides, per channel.The baffle is made from 2 panels of 3/4" MDF glued together and measures 75"H x 23"W x 1-1/2"D. I am using a miniDSP OpenDRC-DA8 and an Integra Research DTA-9.4 multichannel Power amplifier. Crossover points are 300Hz and 3000Hz at 48db/octave slope. At the moment I am using only the xover, PEQ in advanced mode(biquads) and delay features of the miniDSP, and measurements made using the UMIK-1 and REW software , but looking forward to refine using FIR via rePhase.
