Hi X,
Could the enclosure be made from 5/8" BB ply. i may have a line on some of this that can save some $$.

Yes, but you might need add bracing on larger spans. Adjust plans to maintain internal dimensions. I would try to make the baffle thicker with 3/4in if you can get some.

 

[Kokanee]

Understood, thanks.

Some progress
I always wanted to be able to drive the same speakers through an active xo too. Therefore this box will not contain the xo, but connections for low and high. The xo is in its own box, with low and high outputs. So I can use the speaker with this passive xo or through the 6/24 active xo with 2x2 power amps

Beautiful passive XO....bravo Istvan

Plott,

The XO and box looks very nice, well done!

 

[xrk971]

Yes, nicely done! Great idea to make an external box.

 

[Plott]

Many thanks, I am glad that you like the xo

 

[Plott]

Dry fit - check

 

[Vunce]

Coming along nicely Plott!
Your external XO's are beautiful.

 

[Plott]

Many thanks, Vunce
Cheers!

Hi X,
I am now about to apply the alubutyl damping stuff and your picture below helps much. But I can't look into the rear chamber (and I've found pictures with different versions), so I would need some advice: should the Noico be applied in the full length of the side panels in the rear chamber? I don't want to apply too much because I don't want to overdampen the box and kill the sound.
My assistance waits already...
Thanks in advance.

Hi Istvan,
It’s ok to apply butyl damping sheet to the rear chamber side panels as well. It doesn’t need 100% coverage as shown. Even 75% is enough. I like your helper - very handsome looking Abyssinian? Don’t worry about damping too much. That’s the point as we want the cabinet to not contribute vibrations.

 

[Plott]

Hi X,
thank you very much, it helps a lot.
Yes, she is an Aby helping... luckily the front opening is small enough, otherwise I should take precautions against the cat, because she likes small holes, slots, etc...

 

[Plott]

Alu-butyl damping (almost) done, I will do the rest behind the speaker after mounting the cone on the front baffle. Tomorrow I will make the cutouts for the speaker - for the first time ever in my life, so wish me luck

 

[xrk971]

Nice work! Looking great. For cutouts using a router, practice on a piece of scrap MDF to get the hang of it. I have used the circle cutting jigs before.
