Boenicke W22

push pull would result in no pressure inside

Only if wired wrong. And where did push-pull come from?

Ref the little ones there is a whole thread here with m,any clone builds: https://www.diyaudio.com/community/threads/boenicke-w5-clone.310367/

The concept is good, the comment above about colouration rings (pun intended) since the first step in improving them would be to choose a better 3” FR — the dirt cheap Fountek has a quite coloured top. A better box could be done as well.

Re the W22, the opicture of V1 with no woofers seems to be teh same, same volume, as the one with 2 x 15”. I doubt the box is big enuff and the DSP is there to fix that, and i suspect that the ionfluence of the large bass drivers on the midBass will not be a positive thing.

Aha it is sealed. but not from the mid woofer , so there is no bass port

About him, Sven Boenicke...from their blurb I read a while back...OMG...

"Like synaesthesia, Sven can photographically remember sound. He can see its harmonic texture as colour. By storing that colour in his memory, he can vividly recall his experience in the acoustic sound field of incredible live performances even months later. Each Boenicke speaker in its development stage is fine-tuned with his own recordings. The same holds true for our electronics, cables and power distribution solutions. Sven uses his recall of the concert hall reality as the only valid reference to ensure the tuning and sonic balance of all Boenicke products."

The whole pamphlet is written like this.
and people give ME a hard time with my alleged subjective analysis of speakers and acoustics... lol.

This makes witch craft sound like quantum physics. Last time I heard of someone with similar talents, his initials were JC.
