what are you installing in these? several more days of sanding and filling and you'll be ready for black laquer... where did you come up with the plans? sizes? are you installing another speaker in the bottom , making it a sealed cabinet? a 411 in the bottom and 604's up top?

Yep Gloss black is where I"m heading with them, I'm not going by plans, although I kinda was inspired by the Stephaens dream speaker article on 6 moons. It's just 604's up top the bottom hole is the port. The inside dimensions are 18 x 18 x 34.

i think i read somewhere that the six moon guys got the design from a great guy..i wonder if he was compensated for his designs? but im sure if he designed it..it's great. which model 604? for what its worth.. i did some folded horns in 20 coats of black laquer, and i can see every little imperfection. i then built an entertainment center and used "polyshades" its a black stain and polyurethane by minwax..2 coats and it was awsome. tho, black shiny things do show everything so due diligence is required for a nice outcome. it looks as if your off to a great start! i think i remember another poster here building the same sort of cab. i think he was having problems getting alot of bass, but i think there was a crossover issue? the other members will chime in im sure.

Thanks Valhallax, It sounded like a lot of great people were in on the build. My guess is his reward was an awesome job well done. I have one 604 C and one 604 E that are going in them as soon as they get back from GPA (totally jonesing over here!!!)I'm also getting new GPA crossovers for them since the C has a 1600 network and the E has a 1500. That sounds kinda like the 6 moons article they couldn't get good bass and it turned out the crossover was wired wrong. I'll look into the polyshades thing since I'm polyurethaning them now anyways. I still don't understand what made the 6 moons speaker an MLTL? unless they didn't show a final inside picture.

I think the 604 is similar to a 146? Altec published a booklet that showed how to tune a port. I believe Altec use a something called "impedence peak matching." Pretty simple to do, all you need is a small amplifier, a audio tone generator and a VTVM.

No, he designed it for someone else who later claimed it as his and only became aware of all this when someone posted a link to the 6 Moons article in a thread on another forum. They even published some of his private correspondence without his knowledge/consent.

Based on what's been posted about the other system, I'm convinced it's a baffle step compensation (BSC) possibly combined with some CD horn EQ issues.
