1. Smaller and lighter. When made solid, I will be able to work on it and lift it.
2. In it's intended spot, the in-room extension will be around 40 Hz with a sealed box.
3. I will have subs below.
4. Probably easier to integrate.
View from the back:
It has a spine and ribs. It's a basic rectangular box, 60L in volume with the back corners cut at an angle because this thing will sit inside a huge bass trap 1.2m wide. When finished it will have a 1m wide Synergy horn on top, all flush mounted like you would see in a studio control room, but instead of having a solid soffit this will be a bass trap. So of this box, only the front baffle will be seen.
Internal baffle added:
Not too many clamps used:
I prefer to use screws as clamps so I can keep on working. There is no waiting involved and I can get a lot done in a chunk of time.
You can see one of the rear corners that has been cut off.
One of those bits was the last to go on:
They look a bit rough assembled, but edges can be trimmed, it's something I've allowed for.
Driver cutouts have now been done and screw holes filled. All edges have now been planed and sanded flat, but no photo just yet.
Next up I will line the interior of the box with a composite similar to the one used by Terry on his Franks. Basically a mix of cornice adhesive and aggregate in a thick layer with steel mesh reo. Now you understand why I didn't want the box too big, because this thing will be like concrete!
I was working with limited time so to help speed things up I assembled some of the box with construction adhesive. This stuff made me more confident of a nicely sealed box and allowed a bit more fudge factor. I can make very accurate cuts when needed but it takes a lot longer to do it. These days if I can find a way to speed things up without causing problems I'll do it.
On the blog:
They also need feet and will have a speakon connector.
More pics to come.
