Wardsweb, very elegant and well crafted project.

Would you mind sharing the construction details of the curved grilles?

Regards, Marshall.

The gills are made from perfed metal sheets that are one inch wider than the inset baffle. This was they bow to fit the space. They are covered with actual "JBL Blue" speaker cloth that came from the original supplier to JBL. The edges are held on with automotive trim.

Ward do you have any measurements of these speakers ? I also like the grills and want to build something like that to put the finishing touches on my project,but I'm concerned with the metal resonating..Have you heard anything WRT to the metal grills resonating/vibrating ?I have always been told that you don't want any kind of metal in front of the woofers as they will tend to resonate/vibrate.So I was considering a wooden frame wrapped with the grill cloth around the perimeter of the dual 416 woofers.. I just love the look of those though !

If you mean acoustic measurements, no. If you mean dimensions, I do have them somewhere. I just have to dig them up as I started this project back in 2004.

The grills do not resonate. I don't know if it is because they are under tension or if the edge banding being spring metal over rubber helps to dampen them. Pro gear has used metal grills for decades without issue.

Yes I meant Acoustic measurements. Would love to see the FQ response on these...

I just realized your the same guy with the awesome 620 cabs with the 605's in them. Nice.

Very nice work Ward. You got skeels for sure.
If I remember from your web site, you are a car guy as well?
Interesting how cars and speakers have similarities when it comes to DIY.
Cars tend to "expand" more however.......and the performance is more measurable.

Excellent work!

Yes, I am a horn guy.

Here are some A7 that I did in walnut. I ended up selling the cabinets and use the 802-8g and 511B in my JBL's shown above.
