MattSPL Here’s the second sub. I lined the fibreglass box with deadening mat used in car audio installs. Works really well as a sub box for a very quick build.

MattSPL Here’s the first sub build

MattSPL Just found this old thread, so thought I’d update it as I eventually finished the box and bought a UM18 driver and also just got a second UM18 but cheated on the box and used a 125L plant pot made of a mixture of fibreglass, magnesium and plaster.
I will be building 2 new Baltic birch boxes.

Sorry to reply to an old thread but what driver did you go with MattSPL?

The choice of drivers in the UK doesn't seem to have changed much since you started this thread (Sundown, Ascendant Audio and some Dayton drivers can be had from UK/ Europe now) and my thoughts/ looking at the availble options seem to have followed the same path as you (albeit I've built a pair of 120.9W sealed subs while I still think about something bigger ).
Unfortunately, i didn't finish the sub build. The box is 75% complete in my shed.
I was out of work when i started the build and ended up selling the amp. When i started back in work, i didn't have the time, so ended up buying a Velodyne DD12 second hand. I'm now wondering if the Velodyne amp would power a decent driver in my DIY box? The velodyne setup software is very handy, so would be nice to have in a potent DIY sub.

I think the Fi drivers seem to be about hte best available in the UK. The Fi Q15 looks decent and seems to be used successfully in DIY subs.

I would use either "no more gaps" (or whatever you have available locally) or alternatively a polyurethane glue that expands as it sets.
Thanks, ill have a look tomorrow.

Re: DIY sealed sub build

A bit more progress, but made a mess of the size of the sides. Only visible at the back luckily.

Any suggestions on what to fill the Kerf gaps with?

Re: DIY sealed sub build

I guess a 50% reduction in size should be welcomed

I've a feeling i might be in trouble when she see's my sub box, it looks a bit larger than i thought

I am hoping that the 7-8 cu ft boxes will ease the pain over the 15 cu ft boxes she has had to look at for the past year. LOL. If I build them low enough she may not even see them.
