51% is fine! It looked like it might be one of those 38% ones I've seen floating around Much under 50% will gimp your port flow a little at least it seems like it to me...I had an old Dr. Bass cab with a 38% grill and the port would really rattle the hell out of the grill with 3015LFs.

I like this - that’s a great idea except maybe use something like cable ties, wire, ring w/glue, or something that won’t rot and break as fast as rubber bands. Awesome 215, very nice work - and I’d paint the grill too (glossy black).

EDIT: I like your blue grill idea.

yeah, i definitely wouldn't want to go under 50%. i did have a small grill rattle when playing the low F#, but it wasn't in front of, or anywhere near a port. it was near the upper left of the top speaker. i added four more silicone iso-standoffs and it's completely rattle free now.

That seems about right to me too - IE, the Barefaced Super Fifteen has two 3015 drivers and it’s 103dB.

If Bergantino or Eden sold it, they would rate it as 107db since it's 4 ohms

Why stop there?, you're selling yourself short. Hell, call it 30hz for a good low B and randomly pull some other huge spl numbers out of your backside while you're at it. It's what the pro's use after all.

It needs a good name first - hmm, what would be a good name for John's new 215 - the JK Super Crusher?

How about the JohnK_11 because it goes one louder for that final push off the edge?

[kraigo]

I'm in the "leave the grill as is" camp. Nothing to flake off will look nicer longer.

Good work.

you realize of course there's only one color for this cab including the grill, don't you?

[Joe Louvar]

black and blue

[johnk_10]

the grill is going to be satin black epoxy paint. i made my own logo for it out of 1/8" lexan a painted the back of it with silver lexan paint. i'll clean and paint the grill tomorrow and by tomorrow night it should be ready to assemble.

BTW, the cab is 14" deep (not 15"). it's 24 1/2 wide X36" tall and weighs 46 1/2 lbs.

I like model names, man. I can never keep it straight whether somebody has a 21210 or a 21012...it just doesn't sound right. Barefaced has some cool names like the Big Baby, or maybe borrow a bit of Roger Baer's midevil caligraphy and call it "he who doth not to another bow" or something.

Given JohnK's affinity for the best of vintage stuff, combined with the vibe of the Streamliner, should maybe come with a spinoff of the Rocket88 or the Fairlaine or Vista Cruiser or something, with the appropriate cursive font of course.

That's a beauty John!

[Joe Louvar]

Only 46 1/2lbs - that’s awesome.

I think a satin black grill is going to look fantastic - and complete with a custom JohnK logo - well, that’s just over the top with coolness.

What a great looking, well built cabinet. If you ever wanted to start building them for sale, I am in the market for a new 2x15...............................
