lukeamdman Posted February 13, 2017 Author Report Share Posted February 13, 2017 That should speed things up a bit! Read that you weren't making it to the GTG Luke. That's disappointing but I'm sure there'll be another time. Best wishes man. Thanks man! Link to comment Share on other sites More sharing options...
Rowan611 Posted February 13, 2017 Report Share Posted February 13, 2017 Argggg...I can't leave the finish like this. I'm going to end up using the duratex roller, BUT, I'm going to take a page out of Mike's book. He first coated his THT with a flat black latex paint and then just a single coat of duratex was enough. Does the finish look that bad Luke?

Ricci Posted February 14, 2017 Report Share Posted February 14, 2017 Unfortunately yes. It's pretty bad. It won't matter in a dark room after that screen wall. Link to comment Share on other sites More sharing options...
lukeamdman Posted February 14, 2017 Author Report Share Posted February 14, 2017 It won't matter in a dark room after that screen wall. The top and front were covered using the duratex roller, and that right side is how they used to look: I didn't care much for the zebra effect.

3ll3d00d Posted February 14, 2017 Report Share Posted February 14, 2017 perhaps try it again with your eyeballs wobbling from the 140+dB, it might be quite hypnotic at that point Link to comment Share on other sites More sharing options...

Rowan611 Posted February 16, 2017 Report Share Posted February 16, 2017 Looks darn good Luke. The more I see those roundovers in the ports, the more I like them. Link to comment Share on other sites More sharing options...
dsl1 Posted February 17, 2017 Report Share Posted February 17, 2017 I could have cut your speakon connector out too, way to not include it in your sketchup files! Link to comment Share on other sites More sharing options...
lukeamdman Posted February 17, 2017 Author Report Share Posted February 17, 2017 I could have cut your speakon connector out too, way to not include it in your sketchup files! That changes depending on if the box is on top or bottom and also which direction it faces, so I'll just take care of those Link to comment Share on other sites More sharing options...

lukeamdman Posted February 17, 2017 Author Report Share Posted February 17, 2017 What are you going to do with the old cabs? Probably just sell them. Link to comment Share on other sites More sharing options...
lukeamdman Posted February 18, 2017 Author Report Share Posted February 18, 2017 After adding the bracing and stuffing the impedance minimum is still around 13.8hz. The box vibrates a lot less now, so the extra bracing was definitely worth it. Link to comment Share on other sites More sharing options...
lukeamdman Posted February 24, 2017 Author Report Share Posted February 24, 2017 Here's a measurement from the DO cab on the bottom left vs. two of the ported cabs wired in parallel on the right. DCR is the same. I've double and triple checked all gains and settings. No EQ or XOs. That's just shy of a 14db difference at 13hz. Link to comment Share on other sites More sharing options...
Ricci Posted March 13, 2017 Report Share Posted March 13, 2017 Where we at Luke? Any news? BTW next time if ever you need to do a comparison like that just get out the DMM and check the voltage. That way you know. Are you going to fire the vents and drivers towards the center like in the pic above? You might get more gain and a flatter result firing into the wall.

I have all the MDF for the next two cabs and actually had some free evenings last week that I could work on them, but I got absolutely destroyed by kidney stones. Today I'm feeling better and have some energy again but I'll be out of town for the rest of the week. Next week I'll try and get two more finished.

Infrasonic Posted March 14, 2017 Report Share Posted March 14, 2017 Ugh, man. That does suck. Sorry to hear. Man... stones suck! Guess that's what happens when you try and leave the sealed sub world and go back to the resonant world. You get kidney stones. Happened to Rob, now you. Who's next?!?! But seriously. Hope you feel better soon. Link to comment Share on other sites More sharing options...

Sorry to hear about the kidney stones Luke, hope you get well quickly. Link to comment Share on other sites More sharing options...
Infrasonic Posted March 14, 2017 Report Share Posted March 14, 2017 I left "proper" out so you're okay. Or not okay. Go for stones! Link to comment Share on other sites More sharing options...
lukeamdman Posted April 3, 2017 Author Report Share Posted April 3, 2017 I bought the remaining MDF for the last 6 boxes and made 89 passes on the table saw yesterday...I'm starting to see some light at the end of the tunnel. Link to comment Share on other sites More sharing options...
Infrasonic Posted April 3, 2017 Report Share Posted April 3, 2017 Seems like it never ends... Btw, how many of these are up and running or do you still have the sealed system up? Link to comment Share on other sites More sharing options...

I have two of the ported subs and two DO subs in the room. It's been nice to instantly switch back and forth with the MiniDSP to compare them.

lukeamdman Posted April 10, 2017 Author Report Share Posted April 10, 2017 All pieces, including the bracing, are cut. Assembly starts tonight. Link to comment Share on other sites More sharing options...
lukeamdman Posted April 13, 2017 Author Report Share Posted April 13, 2017 Six boxes worth of cuts (minus the 12 baffles that dsl1 CNC'd) stacked in the order of assembly: Here's how far I can get in about 1.5 hours: Link to comment Share on other sites More sharing options...
