OK, compared to most of the builds going on here lately this will be pretty tame - You are dismissed if you don't care about an Infinity 1260w build (technically, my 3rd)
I decided to build a modified version of https://www.avsforum.com/forum/155-di...gn-thread.html
that I'm sure many of you are familiar with (I will have another build thread for that). As these builds are going in our living room I need to be judicious with regard to size and finish, and placement will be less than ideal. This thread will cover the reuse of the 1260w from the first build in my signature to create a twin of the second in my signature.
So, on with the show! (This will go pretty fast, I promise)
Obligatory shot of the panels all cut to dimension. The final outside dimensions will be 19"H x 17" W x 20" D, slot port of 1.5" x 10" x 25", giving a tune of right around 25Hz according to WinISD.
Inner and outer baffles with holes cut (plunge router with homemade circle jig), 1/4" round over on the inside of the outer baffle and a quick shot of black spray paint.
Slot port built and glued/stapled in place. I had painted the inside of the port black when I painted the baffles. I use standard Titebond and either a 1/4" crown stapler or 18Ga brad nailer for my builds (prefer the stapler for more hold, but then you have to deal with larger holes when filling). Caulk on the inside seams.
Sides on, I caulked these seams as well as the front seams before putting the top on. One difference between this build and it's twin was I decided to not cut the front baffle around the port (more on that later).
Both baffles in place with some clamps holding while glue sets. I used no bracing in these as they are small, we'll see how this one holds up as I do notice some seams now in the original.
Round overs on edges, sanded, most seams/staple holes filled with wood filler. Need to go over it one more time with the random orbital. I mentioned earlier I didn't cut the inner baffle around the port? It's no
fun hogging out a full 1.5" of MDF with a straight bit in a router!
NOTE: Anyone not familiar with MDF should know that working with it creates a very
fine dust, that gets everywhere. I recommend cutting/sanding outside if at all possible, and always wear a mask. It's nasty...
Duratex time. I was very happy with the result I got from Restore 4X when I did the first sub, but this stuff is 10x better. After painting this one with a 1/2" nap 9" roller and comparing it to the original build, it's amazing how black this stuff is. Shot of the texture.
Full frontal, for you sub pr0n fans...
It looks more grey here due to the light in the workshop, and the seam on top filled in much better with the last coat of Duratex.
And lastly, with it's almost 3 year-old brother. I put 3 coats of Duratex on the new build, 2 on the original to make them match. That stuff is crazy thick and I probably didn't need that many coats, but it took me a little while to figure out how to work it with a roller. Probably try spraying it next time.
That's it! I haven't had a chance to run sweeps with REW yet, hope to do that this weekend.
Another big thanks to all that contribute here and give inspiration to all of us that don't know much, if anything, about speaker/sub design. And those that do...
