Re: Latest build pictures

Yad, those are very nice!! The use of exotic wood veneers sure can make all the difference. What veneer have you used?

I have not found many pictures on diy builds using EXOTIC veneers, i would love to see what else people have out there????? Its good inspiration!

Ebay has been a great scource for some very unusual veneer.

Re: Latest build pictures

Yad, would you mind doing a veneering tutorial for the rest of us dummies? :bigsmile:

I'd love to learn how to do veneer like you guys. I usually have to use birch to get such a nice finish. Even then, it's never quite like that!

Original Ekta Grande of Troels Gravesen is here. http://www.troelsgravesen.dk/ektagrande.htm

Original construction - is perfect stuff for DIY!!! There are all specifications at this link.


My modifications:

1) i used 2 quasi-separated volumes for LF.
2) Another volume for MF: i used aperiodic (like)IB enclosure (while original was CB)
3) Position of all drivers are closer to the center line of speaker. The box is little wider.
4) Little-bit changed filters

The idea of aperiodic MF enclosure is shown at this picture. Red line - shows this volume for midrange.
The same idea Is used by Bowers & Wilkins Nautilus 801 088 and 802 speakers.

Yad: those are some great looking speakers, the veneers are really classy :) Regarding the aperiodic enclosures, have you made one (you brought that up sort of 'out of the blue'...)? In my N7R speakers I was going for that general shape however in steel (at reasonable cost) the well pressure tanks were the best match I could find :D

Thank you, Matt.
If i understand your question correctly, the decision to make aperiodic enclosure was not "out of the blue"

The idea was to create the box without inside's rectangular shape and without parallel walls inside. But i did have rectangular outside shape. So, the result - is to put curved surface into the rectangular box. It kills the most number of standing aves inside) The result is audible. In aperiodic enclosure gives less coloration. But sounds more fresh and detail, then the box extremely damped with the fiberglass.

Oh; yes, I meant you brought up the topic of aperiodic enclosures "out of the blue" (I couldn't see where someone asked you about them, I didn't realize you were putting them inside of a box). Do you have any internal pictures of your speakers? I would be interested to see how you made the aperiodic shape in the box.
