Funky NS3 MTM Build

[spudfrog]

I've had materials for a small sized set of 2-way speakers for my bedroom for a while, and I finally came up with a design I was happy with. Earlier this week while sick and delirious with fever, I became inspired by the Sony Walkman logo.

I went ahead and started tracing bowls and cups and such until I had a design I liked. I used my router and circle jig to cut out this 1/4" template. I used this template to cut out five identical pieces to make up each side (I only have one side cut atm) Each egde will be rounded over with a 1" radius.

Each speaker will house 2 Aura NS3s, a Daytom rear-mount tweeter, and a premade PartsExpress 2-way crossover (for the time being). I've used this driver combination before, so I'm not too worried about the crossover or the limited space, but ultimately aesthetics were my main focus with this set and sofar they have turned out really nice.

Pretty funky, nice curves. Any sonic objective to the weird baffle shape?

Really nice routing and design!
Unfortunately, i've read that round baffles are really bad for edge diffraction, since the distance is identical to the edge all around.
Keep the updates coming!

Not really, I just happen to put a little more emphasis in the look of my speakers than the sound. I've made several small variations of a sealed enclosures for the NS3s and I've liked how all of them have sounded, so I figured I could take some liberties in the design this time around.

I think ultimately I just don't have a very audiophilic ear.

I finished cutting out the template for the inner panels. I used the circle jig and did the rest freehand on the router table. I sanded everything clean using the router and a sanding drum and it looks pretty good imo.

Nice cabinet , spud !

pre-built x-o... glad you said "for the time being.."

I suspect you may have a diffraction dip somewhere that might be able to be treated with a designed and measured x-o.

but....


Nice cabinet.. please make sure you post finished pics..


ps.. you may find the join lines between the mdf layers a bit had to hide without using some sort of textured finish. have fun

I was thinking about skimming the entire surface with a few layers of bondo, or maybe even covering it with some laminate or even some veneer before prepping for paint.

That looks really funky, I like it! Those NS3s are very wideband drivers, mabye the tweeter would work better as a supertweeter (8k or so), but then perhaps you'll be too far off axis for that to work optimally? Try some modelling with Basta! software to get an idea what the baffle will do

this is what I'm talking about!

I love creative stuff like this. Amazing work!

Much thanks.

Just finished the second cabinet, and all of my main routing is done. I can finally clean up the 1/2" of dust covering an entire corner of the garage.
