THank you! Then I think a6b might be itWhen I look at those measurements, I see two superb speakers. On the S6b, maybe you'll hear the wider directivity in the treble if you can still hear that high (I can not), and maybe you might notice slightly higher directivity in the lower midrange. But both have distortion levels approaching inaudibility at all sane playback levels, though the S6b's appear ever so slightly better in the midrange. I think the bass should be better on the A6b if you're not using a sub, which seems optional with either speaker (at least if you're using them to play music) IMHO.
Biggest difference is the price, and the question for me is more like A6b or C8c ?
I currently have Visaton studio 1 DIY Kit speaker although it came out not perfect as the carpenter did somehow left the depth of the flush mount for the waveguide 2mm too shallow and original waveguide didnt even fit for that so i had to 3d print and try to somewhat replicate the waveguide
Its quite good and it can play really loud without distortion, i feel like its still lacking something around the crossover frequency. I think the visaton tweeter doesnt really like the 1.6khz as i compared it to one another tweeter (scanspeak clone) the scan speak clone sounds miles better than the visaton one.
But A6B it might be then
