Big Radius 2-way

Picked up a piece of 3" radius mdf in anticipation for my spring build. Thought I would let the PS180 have another go, this time with the North D25.

Also going to give Kerfing a shot.



Here, I sprayed the surface and flooded the bottom of the kerfs with water and after 30 secs poured it out and began training the mdf.

I decided to use Gorilla glue. In retrospect, I wish I would have used PL Premium.


This one is awaiting side while the second one is started. They are going to be really big.
Hey, Its a hobby, right?

Re: Big Radius 2-way

Are you going to add a sub? Those PS180's don't really go too deep, do they?

Looking forward to seeing them this Spring!

Re: Big Radius 2-way

Am anticipating putting a Ultimax 12 under them. Inspired by Chucks latest builds. We'll see. This just may be the wrong radius for a "small" speaker, but its what I have. Won't really be able to judge them till I get sides on. For my tower build I may just buy a couple of sheets of bendy mdf. Would need three layers of 1/4.
BIG!!!

Re: Big Radius 2-way

Thanks Chuck. I won the um12 at Dakota last year , will have to buy one someday and came into two knockdown pe 1.25 boxes. Should work ok?

Really neat work. Where did you get the corner from?

Re: Big Radius 2-way

Personally I liked it best at 2 cubes with the pr. Sealed I didn't care for it.

Re: Big Radius 2-way

Another thing to consider is the sensitivity mismatch. Sealed the UM12 is probably only around 80-81.

Re: Big Radius 2-way

What are you going to do for roundovers on the sides?

Re: Big Radius 2-way

Not sure yet. Maybe just an 1/8" relief. By the time the sides are on, it will be 12 1/2" baffle. Crazy huh?
If it turns out well, I might just drop a Rs180p in there.
