Say a prayer that we will continue to have people like this gifted to us. Genius is a beautiful thing and when you see it you tend to notice it is devoid of arrogance. Always.
This man he inspired my technical work, I was 19 years old when I witnessed hes technical drawings on hes website, S-plane drawings and advance research that to this day, I still cannot wrap my head around, he was was responsible for inventing serious microwave equipment for HP, seriously on another level of thinking, yet a gentle giant among those he shared company with. RIP old friend.
Enjoy Siegfried Linkwitz since he was a rarity --- an authentic genius in the audio world who REALLY loved educating people about their SOUND/MUSIC world so much that he did this under obvious end-of-life duress. He was dead not long after. His important legacy will remain for decades.
He was a college of mine - far away, in HP. Working in Test & Measurement, I suppose in Palo Alto. I was actually never aware that he was of German origin, but that is easy to hear in this presentation. The old giants are dying - where are the new ones??
Awesome. So inspiring, for all the BOX lovers, you must watch at 45:03 onwards, No one could get so creative at expressing. Only a master can. May GOD give him good health and a long life to share such wealth of knowledge.
I came down to comments to make one, then saddened to learn Mr Linkwitz had passed. He always answered the few emails I wrote way back 1999/2000s. I suggested magnesium SEAS Excels back then. He didn’t say he knew of them. Oh well, no more emails. Sad. End of an era. His website was truly DIY back then, everything was fully described. Well, I came to make comments. Siegfried can’t respond, but I’ll continue. At around 32 minutes it was stated that some boxed tweeters have large reflectors to focus the sound to match the narrow propagation of a boxed woofer’s higher end. I’ll stand corrected, but that’s very often not the purpose of the tweeter waveguide if used. A waveguide is used (in passive systems or otherwise) to boost the lower register of tweeter beyond what is normally possible so that the higher fidelity/detail of the tweeter can be used rather that of the woofer, or it allows the use of a larger woofer with limited high frequency extension or fidelity. I've read it can also lower tweeter distortion. It also allows the crossover to be at a longer wavelength for a smoother transition or lessen time alignment issues (also mostly due to being able to place the tweeter deeper closer to the woofer's timing). Yes, the waveguide allows a lower tweeter response by horn loading a bit, which I guess is due to narrowing the tweeter lower frequencies, but that’s not a bad thing anyway, and very often not the reason for the waveguide. The tweeter's higher frequencies don’t become horn loaded as they are more directional naturally, so there is extended smoothness anyway. I've even read waveguides are good for dipole systems too, reducing edge diffraction ripple on flat baffles. There’s good aspects to dipole systems, but I’m not completely sold. My small flat doesn’t allow it anyway. I’ll say this though. When someone sings to you, they don’t sing with an extra mouth at the back of their head facing the other way to the wall. Same with brass instruments etc.
So glad you like the SEAS EXCEL from Norway my home country. I listen to them every day with my gorgeous amplfiers from BUTLER AUDIO TUBE DRIVER BLUE and the AUDIO POWER LABS 50 TNT OIL COOLED 572 B CLASS A Filled with fabulous LUNDAHL TRANSFORMERS!!!! BY THE WAY I GAVE UP ON PANEL SPEAKERS A LONG TIME AGO. WRONG PRINCIPLE THEY ALWAYS MADE FRANK SINATRA GIVING HIM A MOUTH LIKE A WHALE!!!!

RIP Dr. Siegfried Linkwitz
I like the L-R crossover system

Siegfried, RIP my friend...owner of Orion kit S/N 1!
HE WAS THE NEIGHBOUR OF NELSON PASS A WONDEFUL HUMAN BEING!!!!!
so nice ! and so interesting .. i really learned a lot about sound waves .. great lecture !
Many thanks

Amazing
Auf wiedersehen Prof. Linkwitz !
i respect this man for all kinds of reasons
Great man indeed. RIP.
@@acerard he died? When?!!
Few days ago :(
what a legend

amt now?
we haven't gone much smarter in audio speaker since a very long time.
it's only smaller or cheaper - not better sounding.
speakers aren't the problem, but recording competance and industry standards which have been slipping for decades

Is this correct
