Speaker for fun :)
« on: March 04, 2018, 06:51:05 PM »
So I started last year slowly putting boxes together to use up drivers in cupboards.  The aim is to do something not too big that does a solid 40hz. I suspect these will be approx F3 @ 38hz. Size 101 x 25 x 36cm, so + on WAF. Cab angles back 5 degrees. Front slot port, I want them to be close to wall friendly.

Drivers will be Scans...  2x18W, 15M, and 6600 or 6620

I have them progressing nicely, managed to get some time in this weekend to slice off the edges. A mission with only a router.. but less time that driving them somewhere, explaining, driving to collect..

Cabs are birch ply, nice and solid vs. MDF, 36mm for bass drivers, 18 for mid/tweeter (don't want the mid in a tunnel). Cutouts are nicely rounded off at the back and I have some broomsticks across for bracing in the bass section to break up the large side panels.

Finish... I have 60 strips in 70 x 4 x 120 american walnut, sanded to 100 grit.. that wasn't cheap  :giggle:... but I think the finish will be worth it.

XO points... no fixed ideas yet, will measure and then think.

Hope to get the cabs finished in March / April to allow me to have a winter XO challenge

yes.. I eventually made up my mind :).. decided against adding the SB 10", I would never settle on an XO with that, or may need to go active which is not the way I'm going.

Well the SB10's can still be actively added adjacent with xover of choice if desired.. with the much lower xover frequency it should work fine. Woofer F3 should require xover in the sub-50Hz range I guess?

I'd think a bit higher if I added I would make the 18w sealed... the sb10s would be the same.. so probably 80 to 100.. would have to be acfive.  However after hearing your subs I'd probably rather remain as is and if I was thinking of serious neighbouring  destroying bass would reconsider the plan. Your subs scared me 😂

I think it was mostly room gain you experienced.. they performed much less terrifying in other locations ;)
Seeing the direction that my new speaker plans are heading they may perhaps end up for sale, or perhaps I'd play with some open-baffle sub ideas.

Lot of effort being done in the prep work.
Cannot wait to see when all is done.
Keep the images coming please.

I like the idea of the wood cladding. I am sure it is going to look great when finished.
Looking forward to see your progress.

Some pics... all work is a few spare minutes here and there..

1) Side panels being convinced to stay on the birch ply.. notice the Federal Barbells have had them since I was 14  :boxing:..
2) back angled sides on... tick.. quite a mission but essential for WAF..
3) The remaining sides for the other speaker.... and my good yellow friend in the background.. we have shared some fantastic times :)

Hope to have these in a sand, sand, sand, sand, sandable condition for next weekend..Lots of work before the end of the road.
