Dimensions for sealed 18" sub box - Page 6

post #151 of 679
Thread Starter 
I hope to get the dual opposed models next week. After Mother's day I'll start drawing up some ported boxes. I hope someone can give recommendations for sizes, tuning, and drivers by then.


Still debating how to do the outer cut outs for so many different driver sizes. Many of them are almost the same diameters, so they can be averaged pretty good. Maybe I can get some blank baffles for the odd sizes and if someone needs help cutting the hole, I could do that in my spare time.....assuming they didn't mind waiting a few extra days.

Those flat packs are so slick!

Would it be too bold to say your my hero?

I think you can get away with saying things like that, but only on the AVS forum. Of course I'm just getting the boxes, you're the one with the beast drivers.


I know this is going to sound crazy, but I'm half tempted to make one model that's way over the top for the monster 18's or 21's. Not many people would buy them due to weight, but they would be available for those that were a bit insane. It's going to be a secret until I can get a prototype made up......if it can be done the way I'm picturing it in my head. I won't have time to draw it out until after Mother's Day though.

Verrrry nice! One question, why have similar enclosure sizes like 3 and 3.5 cut ft?

Are you trying to say that it's NOT normal to have 10+ subs? It's only insanely genius to have a large selection of subs to choose from

Because some people are crazy with internal volumes.

Just kidding (sort of). The 3.5 model is taller versus a square cube. So it looks a little different and would be better for a ported design where the port might need an elbow.

Some models will be tweaked and/or possibly eliminated while others are added. We'll just have to see how this all works out.

I was hoping to get 1 cu ft up to 6 cu ft with about .5 increments. The .5's could be made taller versus square. It was just a thought though.

That is awesome. I am very interested. I was planning on getting 8 of the 4.5 cubic feet boxes but I will wait to hear about the "insane" option. I plan to use 8 of the UXL-18's right now but if you design a box for the 21's I will get 8 of those instead. How about something like a 24" cube? That would be about 6 cubic feet with bracing. That would be perfect for the Mach5 21. I would be in for 8 of them for sure. Thanks again for all you do.
post #158 of 679
Eric, those looks great, nice to see one with the driver sitting in it as well, very interested in 2 12s or 1 12 and 1 15.

24" cube probably wouldn't work too well. The CNC machines use a 1/2" bit, so unless they got 5'x10' sheets and cut them in half, it would be tough. And 5' wide sheets would give a lot of waste. The boxes could possibly be 23" wide, but taller to get the extra volume.

And keep in mind, those would be some seriously heavy boxes to ship. Certainly 2 packages for each.


Also, I wouldn't wait for the "insane" box. It might not even get done, it was just a thought I had.

If the "insane" box was around 8 cuft you could fit some of the larger pro drivers (and the XXX18) in the 18 or 21 range and could give the option of either having it sealed for some of them, or you could open it up with a port using the same design possibly for other 18 or 21s that need bigger ported options!

I was just throwing the 24" cube out there. I would be thrilled with anythi9ng in the 6-8 cubic foot range. Space isn't an issue. I would be in for 8 and I am sure there are several others who would be interested who are looking to get 21's.

Are there serious plans for dual-opposed 15's or 18's?

You'd have to give me the sizes and shapes so I could find out. I don't know if dual 18's means 6 cu ft or 12 cu ft.

Right now I was just making the typical boxes because no one has really given other ideas to look into.

Dimensions and what drivers would really help me out.

7 cubic feet boxes for mach5 21's.....

I'm thinking 5 cu. ft. for the dual 15's and maybe 7-8 cubes for the 18's. The dual-opposed 18" model might be problematic logistically (sheets of wood, shipping size/cost, etc.)

post #166 of 679
Erich, you said you would be drawing up some ported boxes soon? Hopefully someone can get some designs to you for the 15" Dayton HO/HF with maybe the 300w amp and the 15" Titanic with maybe the 500w amp.

Can't wait to see how it all turns out!
post #167 of 679
how are those weekly updates coming along, can't wait to hear some good news
post #168 of 679
I am ready to buy two 4cft boxes as soon as they're ready. Then two more if the first two goes smoothly.

15" LMS-Rs here I come. *waiting patiently*
post #169 of 679
Hey Erich,

I hope I haven't been bugging you too much with all the emails I've been sending you. Anyway, getting really pumped about these flat packs. I have one question, you mentioned that the volume of the 12" box is 2.25? I would like to put my 12" LMSRs in something more the size of 1.25. But, 2.25 will work too. Just getting some clarification on that.

Thanks,

Bradley

Use the smallest box if you want. Erich's indicated it would be roughly 1.25cu. Just route a larger opening for a 12" driver and call it good. That's the nice thing about having different common sizes to choose from.

Man Erich,

This stuff is looking great. Can't wait for the 18's flats to come available. Got a a few friend looking at wanting new subs and a couple who DJ and really liked those Econowaves....so I might be supplying a few folks here in Houston lol.

Does anybody have any recommendations on drivers and stuff to use with the 18's and Econo?

There's a lot of good sub drivers tested recently.

If your Canadian the UXL-18 is good and has a smooth response.

The Sundown Audio ZV3 18 was brought to light by WiSounds and tested recently as well.
It has HUGE XMAX, can take over 2000 watts, and is supposed to be a very quietly operating driver ( I bought his one for sale ).
post #173 of 679
Man, I'm itching over here waiting to see some prices and deliveries. Plan on getting some 1.25cu or 2.0cu boxes myself for some 12" Dayton HF drivers.

Has anyone thought about or come up with any grill ideas for these yet?

Pictures should be going up today or tomorrow morning now that I'm caught up at work.

I'm going to contact PE to see about getting any discounts on their drivers/amps that may help lower shipping rates. Luckily I live within driving distance and could pick up stuff to make kits.......before the big subwoofer prototypes are delivered for testing.

Still a little worried about shipping the larger flat packs though. I'm suppose to get some "sample" double thick boxes this week, but that won't keep me from starting to ship these out. I've got some pallet corner protectors that can be used to protect all the edges on the flat packs, so that should be good enough to get things rolling. It's not easy finding the correct sized boxes and I'll probably have to cut each box down to the right size.

Any brilliant ideas for matching cutouts with certain drivers? The kits will match up perfectly but what about the other ones that I don't actually have to test fit?

I really don't want to buy an 18" LMS just to test fit the diameter of the cutout. Should I just get holes cut 1/4" bigger than the manufacturer specs? That would be 1/8" clearance all around.

And what about recessing them? They all have slightly different depths.

drive to PE and test fit the lms =p, can probably convince someone to let you do that lol.

That's not such a bad idea... Just make sure to tell them that it could raise PE sales

I'm also watching this thread like a hawk, waiting to get my hands on 4 enclosures!

Enrich,

Do you really need to test fit the cutout for every driver out there? I understand you want to make sure everything fits perfectly together but I think this may be where we can contribute to the project a little. We can compile a list of drivers/cutout diameters we used on our previous projects, may be start a separate thread here in this forum. Then you don't have to buy all the drivers under the sun to know the proper cutouts. You have already done all the hard work, we can at least do a little to help.

You don't plan on stocking all the cutout diameters, do you? With the combinations of cutout diameter and box sizes, the number of front panels you have to carry got to be a very large number. What is your plan on that?

This is a great idea. I would be willing to help in any way I can.
post #180 of 679
What are we talking about exactly? driver cut outs for the frame or driver cut outs to fit the basket?

If the former then beggars cant be choosers and all, for a $150 box i dont expect the driver cut out to be perfect, i didnt even expect a driver cut out at all, i just expected to have a driver frame resting on top of wood, no biggie...
