Re: Big Radius 2-way

I was mistaken. I have a 10" Ultimax. Chuck, do you think that will work well in 1.25?

Very nice, Lowell. I wish kerfing did not generate so much dust. Nice results though.

Re: Big Radius 2-way

The baffle is so wide and with the tweeter offset, the tweeter diffraction is out of the passband.
Really I didn't know where to stop and start. As it turns out, I should have made a few more at the top, there is a bit of a flat spot. As it turns out, I should have stoped sooner at the bottom,m the kerfs are in the glue joint and I had to cut it with a circular saw.
I will do better in my summer build.

Re: Big Radius 2-way

Arlis , Ive yet to attempted a kerf build. How do you know where to where to start and stop the kerf slots , if I may ask? Going to follow this build !!

Re: Big Radius 2-way

A pair of PS180's lurk in my garage. I'd be interested in your opinion of them.

One design Q here, though - a large radius edge is often used to better manage diffraction issues - normally in the horizontal plane. Yet, this design will use the large radii for the top vertical edge only. Is this just a stylistic expression or is there some function behind the form, too?

Thanks, looks interesting.

Re: Big Radius 2-way

This is kind of a pre amble to a build I have planned for the summer.

Re: Big Radius 2-way

Cool build

I've done a few kerf cut builds. Lots of dust and lots of work, but results can be pretty cool.

Good luck

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.

Re: Big Radius 2-way

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

I happen to have a sa1000 as well. ;)

Problem solved!

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

Re: Big Radius 2-way

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

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