Thank you for good evaluation of my work! Ihave long been thinking about chainging the Tw with " crescendo" -SEAS. I have always wondered why SEAS do not offer this one Tw in a similar color of "Excel"- obviously a not well thought- out commercial concept.Agree with me, that these columns will look more lnapproprite with the color of the "crescendo"

Great work! The 33Hz F3 in 31l closed box is overly optimistic, my estimate is 50-60Hz. Drivers look like those from Seas Thor TL.

I have finished several heavy projects, today is  Dimitri's day / Happy celebration of all with this name /, i.e. winter is coming in and I start working on stands of the rear loudspeakers, a few picture:

Završil sam nekoliko teških projekata, danas je Dimitrov dan / Sretna svečanost slavlje svih koji su s tim imenom/, tj. dolazi zima i ja cu počinjem raditi na stalcima stražnjih zvučnika, nekoliko slika:

Cheers!

Živjeli!

I will open an interesting (for me) topic, the seasonal movement of the MDF material.
You assemble aLL of  details in konstrukcion, everything is fine, but after two or three seasons, you can see all assemblies and details similar to this item: 998653641_.jpg.2e0c50c516d818c5133db0c54395dcf5.jpg

I'll show you what is my solution to this problem, for more than 10 years, everything looks like it was at the beginning.
After assembling, I make a whale, with MDF waste material and a polyurethane primer to coat the workpiece;

"The unique and patented Hegel SoundEngine audio technology is combining the advantage of class AB-amplifier and the advantage of class A-amplifiers, without having the draw backs of class A and class AB-amplifier technologies. The SoundEngine Technology will cancel crossover distortion found in all types of class-AB amplifiers. The human ear is very sensitive to high frequency distortion components in the music signal. The Hegel SoundEngine technology will cancel high frequency distortion components found in normal types of audio amplifiers. The Hegel SoundEngine technology is not using any kind of global negative feedback, it is using local and adaptive feed forward technology if there should ever be any need for cancellation of distortion within the audio amplifier stages." -Hegel

While the H360 does not run hot, it uses no switching power supplies or any mix of Class D technology. It is a 45-pound Class AB amplifier all the way. The cosmetics remain classic Hegel: simple, pleasant, subtle, functionally proficient...Scandinavian.

Nemam pojma što znače srca, različiti pehari za pobjednike i posebno izmučeni palčevi, spremni ući u vaše dupe svakog trenutka!

Naravno da znam, ali ne volim lijenost, svi ti emotikoni - nakaze.Кada želite razgovarati s nekim, zapišite im nekoliko redaka svojih misli, znak poštovanja, empatije i ne umetajte tuđe misli u obliku emotikona, srca i palca. Uvijek sam bio protiv simbola koji se koriste na forumima, uvijek!
Ako zamislimo situaciju - bugarski i srpski  pijanci, pali tipovi za jednim stolom, kako će se razumjeti? Naravno na engleskom. I umjesto da jedni drugima kažu; zdravo brate, kako si? Nacrtat će emotikone i palčeve.

PS
Moje mišljenje, izvinite me, molim !
Tko je shvatio- razumio..  Živjeli!!
