Yes I think too that need multi-channel amplifiers and need a very hard, powerful amplifiers.
I mentioned here that earlier 7 years ago I had only one subwoofer ready and I connected two step-up transformers, making the connection in series-parallel, which means the transformation ratio was not 200, but 400 times.This sounds excellent. Congratulations. Can you post some more clips please?
The spectrum of the plucked double bass intro in your youtube clip shows very clean peaks. Looks like your ESL bass panel design does great impulse. Gives that dynamic live sound:

The frequency of a single 50/50cm membrane is very low. But with a set of six membranes, it rises. This problem was partially solved by acoustic loading between two packages (the photo shows how two packages have the shape of an ajar book. The natural resonance of such a construction cannot be considered in isolation from its coordination with the acoustics of the room, they have a direct connection. Of course, such a package in the open field will behave completely differently.Hi Havun,
thanks for sharing your story about these creative stats! I really like your woodworking skills and the non standard design.
I've never thought about generating esl low frequencies using an isobaric esl configuration. If I'm correct one woofer / channel uses six diaphragms? The problem I foresee is a rather high fundamental resonant frequency because of the rather small area compared to a single diaphragm, which limits low frequency range. Not sure if my idea is correct?
In this case, not only to increase the sound pressure, but also for a higher accuracy of the arrival of high frequencies in TIME.There was already such a bent design to produce, I suppose, higher sound pressure. Sectioned ESL. Curios ones may waste time using G...E.
That is quite impressive output!... My ´small´ panel was measured with 110dB@4m, at a power level of roundabout 50W.
