Default SDX10 in 24L sealed sub build

Here is a sub build I started last weekend, the title pretty much says it all. It's based on the SDX10 by CSS in a 24L enclosure powered by a BASH300 amp in its own enclosure.

The enclosure will have curved sides made by laminating 1/8" baltic birch ply over the frame. I don't have any photos of just the frame but here it is so far for those interested.

In the end the top and sides will be covered with walnut veneer. the back and bottom will be covered with black felt, and the front will have a slight curve and covered in black leather.

Below you can see the front baffle so far with the leather on it.

I'll post more pics as I get more done, I have to go pick up some more glue for the final lamination tomorrow, then this weekend I should get around to putting the veneer on.

Let me know what you all think,

Nice design. I like the black leather on the baffle. Looking forward to seeing it finished.

That is one of the nicest-looking subs I've seen in a while...

Would you consider making some satellites to match???

I think that would look very nice.

Very nice looking !
It's shape is similar to my latest speakers: Black

We used different process for the curved shape.
I will probably try yours in a future project, I definitely love curves (not only for speakers )

What was the reason for you to use the sealed version instead of the ported one ?

Default Progress so far

Thanks for all the nice comments guys!

As for figuring out the shape, well I just started sketching till I found something I liked the put it in cad to get some dimensions on it to make sure I had the proper volume. Then once I found the right shape I made a large circle jig for my router and made the top and bottom. Then glued the top, bottom, front, back, and braces together to make the frame, started applying the 1/8" laminations, and today put on the veneer.

I do plan on making some front speakers to match, I started a thread on them in the speaker forum. They will be based on other drivers from CSS.

As for going with the sealed version, well I just like the sound of sealed.
(and those "Black" speakers look amazing! well done!)

Tomorrow I will try and get some pics up, I spent all day today putting on some veneer and some last touches and didn't have time to take pics while I was doing it.

Nice job on your sub... I am currently building a couple of subs using the same driver (however my builds are ported).

I am really intrigued by the BB 1/8" approach for construction. I have a number of 1/4" sheets of BB and wonder if I could get them to bend sufficiently.

How did/do you intend to "trim" the layers of plywood to match the front and back baffles? I assume a flush trim router bit could be used, but one would have to be very careful while routing as the sides arenít flat.

Looking forward to the finished product...

Default Update

Here are some pics so far.

First is with no finish on the wood and the next two are with the first layer of wipe on poly.

To trim the front and backs I made a jig to hold it in place on my table saw sled. Basically I clamped some scrap mdf to it to hold it straight then cut away.

Hopefully tomorrow I will be putting on the second and third (maybe final) coat of poly and will post pics with the driver and front baffle all installed.
