ekta grande

[xmerlin]

Hi to all,
I just want to share my DIY adventure building a pair of ekta grande speakers:

I like them so much ...actually I drive the speakers with two hypex ncore 400.

Best regards,
Christian

Wow, looks like a lot of effort was put in the build!
What is that finish ?

 

[Richidoo]

Very lovely! You do fine work, Christian.

What is that foil-covered material labelled "StP?"

How do they sound? Sonic strengths and weaknesses?

Very lovely! You do fine work, Christian.

What is that foil-covered material labelled "StP?"

"STP SILVER is a self-adhesive, flexible and elastic, 2mm-thick sound insulating material. This sound deadening sheet is a multilayer combination of an aluminum foil and a polymeric layer on butyl rubber base (alu-butyl)."

It's tipically used in car audio and it's very stable during the years.

How do they sound? Sonic strengths and weaknesses?

I like them so much, very neutral, great mid-high and very deep basses.

I'm using these speakers with hypex ncore 400 and I think they are extremely sincere and doesn't colour anything.

I'm finishing my Nelson Pass Aleph p1.7 ...I'll post some additional photos when it's ready.

The setup I've in mind is based on two ekta grande speakers + 1 ekta-like central channel and two surround speakers.
I've already designed from the ground a multi-channel aleph p1.7 and it will be paired with some hypex modules.

When the pre is ready I will start to create the ekta-like central channel.

Bye,
Chris

Astounding Christian!
He-he, I'm just wondering why the tweeters aren't on top?!

I've followed the project of Troels Gravesen and as I can see they are in the right place

Yeah,
Troels is so boring that he never leaves a space for improvement...
He's great.

lol ...you are right

I'll experiment a bit more when I'll start to build a central channel based on ekta grande

Crossover question

Wow, lovely job! I am also contemplating building a version of the Ekta Grande and would be grateful if you could answer a question for me.

I notice that you kept the bi-wire binding posts but bridged them. Did you have to make any change to the cross over design on Troel's site to allow bridging. I just want to have one set of binding posts on mine.

 

[Inductor]

I suppose there's no difference. most speakers, e.g. Focal, have one set of BPs. Usually the opposite is true, some are difficult to reverse from one set to bi-wire or bi-amp, also because of the layout of the crossover board.

Nice work Christian!

Interesting pictures! Looks great! These are the first Ekta Grande I have seen with the new design. Thanks! Are U still happy with the sound?

Ekta like center-channel

I am also interested in your work with the ekta-like center channel build. Any drawings or pictures? I think I will make a ekta like center channel myself if I'm happy with the main speakers. I'm just not there yet

Beautiful work!
