Ok, measured the cone, its 6" roughly and the cone without any yellow is about 5.75" so I could mask it up to that point. But you can still see a thin yellow ring. To me, seeing 3mm of yellow vs 12mm of yellow is the same thing. It's there. Less doesn't change it much. To me. Will see what the wife thinks. She definitely hates the yellow lol.
There is a 2~3mm gap between the driver cone and the material, so it shouldn't impact it since its not going to try to play double digit frequencies.
Next up is measuring this monstrosity.

Ok dirty quick measurement differences, same baffle location and distances, no gating or anything, so this is not anechoic and there is influence from the room. But, it gives an impression I think. This is one driver in its baffle, surround exposed, the other driver on the other baffle, surround masked. The blue is masked. There was actually more bass from the masked version below 200hz. I wonder if the pressure at the surround up against the baffle loaded mass onto the cone a bit or something. Treble and mids are basically the same. So looks like I can mask this driver, if I have to.

Haha, yup. She can live with it, I'm just trying to actually get the family's opinions since its going in the living room. Ultimately I can do whatever I want with it. But I'm trying to consider their thoughts...
Very best,
I'll do a better metric in a bit, gate it, to make sure I'm not just looking at bias.
And I got them backwards. Blue is unmasked. Lighter color is masked. Derp.
There's a phase flip here at 600~620hz. ANd against heavy at 8khz. Unmasked.
Masked has less deep phase activity.
Very best,
That's a very good point, I could do something like that. I'll look around for a bone/ivory color maybe. Otherwise, might just go brown. If it works on that, maybe it could be done to the entire surround.
Still reviewing the above masked vs unmasked response. It is different of course. Though when listening its not super obvious.
Very best,
As for preference, I just DSP'd the top end down a lot with a curve similar to what a contour filter bending it down would do, starting around 2khz to flatten it, and I honestly like it better with the higher treble. It sounds immediately veiled with the flattening curve. So maybe I'll accept the treble spikes.
So really just comes down to seeing the yellow or not I suppose. I like the cone either way. I would prefer to see the surround, I just wish it were ivory/bone color. I can live with it being masked, could try coloring the surround with a marker to a brown or ivory if I can find an appropriate color marker. Or leave the yellow.
I have many days to work this out. The baffle is no where near being done anyways.

yes, dsp is a nice thing. Off axis response is important, too.
Some use even Karlson type diffusing element. And you could dsp it then until it sounds good again.
So a smaller opening can help dispersion - not only the optics.
I am thinking of putting a fullrange in a short front horn and linearize it again with appropriate EQ just for the efficiency.
At the moment I like this beast a lot: Fullrange 38cm guitar speaker, heavily modded and piezo above 4khz. Only one LCR turns 2khz bump down. Side piezo gives something to the indirect sound field.

I build a “waveguide” for the front of markaudio speakers and the first implementation extended to the cone, covering the inverted surround. It caused a bunch of distortion.
Interesting, how'd you assess the distortion to be distortion?
Very best,
Thanks, interesting. So just increased distortion, do you recall about how much? Unacceptable I imagine? No response changes?
Very best,
From this, I just went back and looked at distortion on my two basic measurements of masked vs umasked, and yup, more distortion on the masked version from 700hz down, 2~5% more distortion immediately.
Very best,
Whats with Graham BBC monitor LS 5 / 5 ?

I imagine there is a reason for it, much like I see it's purpose with bass woofers in various builds. Just not sure how it would work out for a wideband. Maybe it's good for bass woofers and mid-woofers, potentially. Maybe not great for a wideband. Would be interesting to know more about that last one, where its all masked and what the effect is and if it's worth it, or what it's doing.
Very best,
How about a series of felt rings? Or, gasp, a grill cloth?
