Note: I've heard these speakers twice: once at the factory (whilst standing) and the second time at the Tower Mains' Berlin launch event (where a packed room forced me to sit directly in front of the left speaker). I am therefore unable to comment on their sound quality. IOW, this is not a review.

As an engineer, I really appreciate Heinz' approach. There is more to speaker design and test than measuring frequency response, directivity, and sensitivity. Without transient analysis, you know almost NOTHING about the speaker -- although pundits tend to use these as their only measure because they don't understand the physics of transducers (and designers are loath to mention anything else).
It's a bit like judging car performance by paint color, top speed, and stopping distance! Or a violin by the topmost and bottommost notes it can play. Or judging a piano by the number of keys it has. Consider a pipe organ. Just one may have twenty-five pipes that play exact C# 4, but each one has a bunch of individual character that cannot be defined by "C# 4". Speakers may have the same qualities. There's (among others) attack, decay, time-to-sound, harmonics, harmonic development, levels of of each even and odd harmonic, and so on. As a physical transducer, which cannot be perfect, each speaker has 'character' that can be mostly defined by time-domain as well as frequency-domain response to various stimuli.
Pundits are relegated to "wine-judging" kinds of words to describe what they hear -- because there are no transient and impulse test results to examine. One speaker's "thunk" is another's "whooomb". One tweeter's "tink" is another's ka-plink". One transistor's "crack" is a tube's "crush".
I get the impression that Klaus Heinz quite understands this. Thanks for this interview. Keep on keeping on.
I like the no-nonsense approach.
Mr. Heinz is obviously very passionate about his designs, and his field in general. I love the enthusiasm he brought to the table, fascinating video.
A very valuable interview. Thank you.
Great interview with a knowledgeable and straightforward scientist. Go HEDD!!!
Really interesting and well explained
Thanks for this! I hope I get to hear them one day
i like this talk and his ideas :)
a few things that stood out to me was:
first the sealed cabinets design, i really appreciate this, he knows what works and not afraid to use the knowledge.
second the amps, those are ICEpower Amp's they are using, i got a power amp myself with those and really like the sound and power, also those run with low noise and little hiss, and do not get hot because of efficiency. dont hurt that they are very small also.
thirdly looking at the website they have graphs showing equalizer response of linkwitz transform, and its it seems like the subwoofers rolls of like you normally would think and not the -3db he said, and equalizer response is adding 14db to get the 20hz at -3db output.
Note: I've heard these speakers twice: once at the factory (whilst standing) and the second time at the Tower Mains' Berlin launch event (where a packed room forced me to sit directly in front of the left speaker). I am therefore unable to comment on their sound quality. IOW, this is *not* a review.

So are hedd going to lend you a set?
I chose the Type 20 instead because it's far more likely to work in my room.
Sweet look forward to the review.
Yet another excellent Darko interview.
I think it's absolutely beautiful.
Great vis and a Krause is so passionate - love it and would love to hear these babies
Nice video and interesting. Owner of some hedd type 07, very good studio monitors that are less dry/cold sounding than most studio monitors.
Really interesting video. I still use the ADAM P22a's. They're fantastic monitors so I'm sure these will sound incredible. Thanks for posting John!
Beautiful. It all makes sense to me.
I would buy them based on his German accent alone
I agree !!!😆🤣😂
I know 1 thing , its beautiful to look at
It’s very beautiful
Good stuff!
Real genius. Bought a HEDD Typ 07 today and im very curious

THANK YOU!
Interesting bit at the end, amalgamation of subjective judgement becomes objective measure in the end.
This man has a lot of knowledge I would love to talk to him
i'm not sure i understand what mr Heinz is referring to by 'dynamics'.. anyone can help out a bit?
"When I design, I don't sell". I'd bet my bottom dollar he has a degree in engineering and experience in sales.
Of course; every business creator is its natural sales leader.
He's actually a physicist
We already have set in China, the sound get a lot of praise
Would be a heck of a soundbar placed horizontally.
Smart design
Great talk. Closed box sounds better.
Very nice interview. Is it class ab or d amp?
Class D.
Looks deliciously expensive:)
this has DSP?
No. All analogue active xover.
Interesting about measuring dynamics. Hmmm
If more engineers were half as eloquent, I think the world of music reproduction would be much better for it.
27000$ pair.. :)
His DSP ruins his designs with analogue inputs.
