Dimensions for sealed 18" sub box - Page 10

Not all boxes are posted yet, but it's getting started. The cut outs are done by CNC. But I'll be doing the 1/2" roundovers by hand myself. I bought a small router table last weekend and set it up. I don't mind doing the roundovers by hand because it's pretty simple. Dusty though. The current sealed subs are pretty much ready to go.

I've been trying to figure out how to organize all of the options so that each person doesn't have to contact me to say they don't want roundovers, or they don't want the driver recessed, or whatever.

So I spent a while this evening figuring out a way to put those options on the website.....and it worked! Probably easy for some people, but not as easy for me.

Here's the first trial I did:

This will allow someone to pick the woofer cut out they need. I figured out how to make it so you can only choose one option there. Then under that they can select if they want roundovers on the front edges, or whatever else I can come up with. Some won't want the driver recessed at all so the screws can bite into the entire thickness of a double baffle.

That area lets someone choose more than one. The 2" thick option was just put there as a trial. If chosen, it adds the extra amount to the total price. Pretty neat. I really don't know how much the extra thick option would even cost, it's just a trial right now.


The only problem I see is that I don't have access to a lot of woofers yet. Basically just what I can pick up from Parts Express. Manufacturer specs are simply not accurate enough and I really need to double check that they fit the holes. Over time maybe forum members that cut their own holes could trace the exact diameter onto a piece of paper and send it to me. I could then cut that circle out and make sure it fits into it's matching baffle. That way we could slowly get more cutout options that have been verified. Guessing really isn't a god idea.

It's not like a million of these will be ordered, so I'll see how the extra options go. I haven't had any problems keeping up with the Anarchy TH's or the other stuff. I'm a little worried about the waveguides coming in next week, but I'm going to call on friends to see if they will help out with that initial rush.

Only the shelf brace runs completely across the middle of the panel. I made sure there was enough clearance for the amps if the end user glued the box together, then cut out a hole for a plate amp. This was the only way to make sure the box could be used for pro audio amps and plate amps. There's really no other way to do it.

Eventually there will probably be kits with the amp cutout already there. But the brace will look exactly the same.....minus the part that you would have to remove right now.

I haven't had any of those made because I was worried about the shipping weight issue.

I could try to get a prototype box cut next week if there's time. It would need to be shipped in 2 separate boxes, but maybe cost wouldn't be as bad as I'm thinking.

I've got that information written down somewhere and will eventually get all that posted to the website. But I'll find it today and let you know.

If you recessed the JBL a full .75" it would be 10.5" to the bracing, so you would be fine. If you mounted it on top of the outer baffle, it would have 11.25" before the bracing.

I'll be checking with PE to figure out kit pricing. I'm actually heading up there tomorrow and hope to find out then.


Keep in mind, I run a landscape business right now, so the audio things can never happen quick enough for everyone. That could change in the future if I have to hire someone part time to help with all of this. It was talked about on a different forum that maybe I should. Things would certainly move a lot faster, but I haven't decided yet.

I'll be double checking all orders tomorrow and Wednesday. Any order that has been placed up to this week is guaranteed to go out this week because I'm taking off some days of work to get everything caught up.

After the container of waveguides and compression drivers came in, all the people that preordered those sent in orders for the compression drivers. So there were hundreds of emails and over 100 orders come in within a few days right when the subwoofers started to move. I think some might have been buried. Obviously yours did and I know of another one as well. Sorry.

I decided to ask one of my friends to help me get things under control so I have time to post the other subwoofer box models that are now ready to go as well.
