I've messed around with ribbons on waveguides, and found a couple of issues. First, they blow up quickly. Second, the response usually looks like what you see with the larger ribbon from yesterday's post. Basically, at high frequency there's a lot of peaks and dips on and off-axis.

This is because of the geometry of the ribbon. Due to the large size, we're getting peaks.

So the performance of the LCY ribbon is exemplary. I imagine it's due to the small size of the ribbon and the excellent geometry of the horn.

As far as it NOT being constant directivity, I wouldn't expect it to be. It's not a CD horn.

I think that ribbons are attractive as a source for waveguides and horns, as the last octave tends to sound cleaner than a compression driver, due to the very good CSD.

Default Current Pricing for Group Buy

Ive been away from this thread for a bit so please forgive me if i missed an earlier post with explanations.
Is there a current pricelist for the group buy that includes new waveguides/horns like the EJMLC-600 ?
Or does the DIY Soundgroup website reflect the current pricing ?

And just for kicks, anyone care to comment on how the JMLC-200 would work with a fullrange driver like the Fostex F200a ?
I just happen to have a pair that need a new/interesting home.

Thanks all,

Daniel

Yep

The BMS performs pretty darn well. I have a Fountek ribbon here that I was going to try in some Unities, but I'm leaning towards going back to a compression driver because the ribbon sounds strained, and I don't have a compelling reason to use it.

Well, besides the novelty factor.
