Hi
In february 2017 I stumbled upon these in a big shop nearby, playing and for 900 €, which was cheap then. They sounded good and also would fit in my 'double-bike-back-bag'! Slept on it and the next day I could'nt resist buying them. As been said before, they don't go deep and sound rather 'present' because of the rise between 2k and 5khz, which, I thougt, could have something to do with the baffle step and a relatively simple crossover, so i began experimenting with dampening materials on the baffle, hoping to 'tame' this area somewhat (assuming it being in-phase relected by the baffle), reduce diffractions, and at the same time 'isolate' the uni-q a bit. Mechanical equalizing.
They ended up with a layer of a rather loose kind of wool felt covering the baffles. This make them sound more 'mature', more tranquil with a bit more of the higher treble, and , I think, better stereo-depth, and somewhat headphone-like, with this typical better (left/right) detail response.
