I messaged you recently to help you out.
I have to mention though, by having the design look a certain way and only operate under your given dimensions, you may cause quite a bit of limitations on what the design may bring to the table for performance with other possible design styles.
I can work with what you have, all day long, and get you a wonderful design with great performance, but depending on your personal preference of response output with only using a conventional type design idea, you may not get the results you are looking for. Still a possibility, and worth looking into.......just making you aware that if another design idea came along that can perform better than a sub up port back conventional br design with port in the middle, then I would not look past it if it can do much better than the idea you are looking at.
but again, it may work very well. Worth the time to take a look and see what we can come up with if you are interested.

Gave it a shot for practice...

4.5 Cubes per chamber, tuned to 32hz with 3 inch slot ports. Designed for dual 3/4" Baffle.

No clue if it's right or not, you'll be better off with a pro's design.

awesome design rendering but airspace is a huge constraint seeing as this box is sized more along the lines of 15 territory.

op u might need to run 15s or give up more height to gain airspace

Thanks.

I don't think it will work either, 4.5 cubes is kind of a strange measurement, it's too much for most 15's and not enough for almost any 18.

You'll need to figure out what you want to do, but I wouldn't run 18's unless you can find at least another cubic foot per side.

can you sketch the exact same box in the pic but with my measurements W43 x D30 x H22 tuned at 32Hz???

Done.

Comes out to 10.8 Cubes Net @ 32hz, 10 inch square port, 16 inches deep. I added vertical bracing, but lateral would probably be needed as well. Once again, double 3/4" baffle.

I believe the minimum they have posted it 5 per, but even at 6 I think you would still be mechanically limiting the sub, 7-7.5 would probably be optimal.

My knowledge is SQ based, so if I were to tell you anything about an SPL box, it would be a complete guess.

Yes a pro box or A-trend. A lot more cost effecient and likely louder.

Dammit do you want me to build one for you too?

pre fab sunwoofer box - Google Search (http://www.google.com/search?tbm=isch&source=mog&hl=en&gl=us&client=ms-android-samsung&tab=wi&q=pre%20fab%20sunwoofer%20box&sa=N&biw=400&bih=537#i=31)

Also go sealed....because ported boxes loose to much air. You want yo keep the air inside the box.

I don't understand the box design in that pic by looking at it. It just looks like there's a hole in the box to me.

That ***** = weak. You need like a 4th order loaded horn enclosure for those woofers....and they are really easy to build. Just ask the big dogs....repoe Sanchez, Frankie friloes, Tommy mcdenny , neil barbecue, or any other big name....its a proven design.

Yeah the port needs to be 86'd .....only gets in the way of the debeez....


I would do 9.6746 net cubic box with in the port..... port size around 476.890 square inches of port.... but with no port.

twisted get your drunk *** to bed before this kid starts to believe you.

op the box that was 10.5 cubes will work but you are going to need more than those 2500bdcps to get any real use out of the subs. in that box they would prolly take double that and prolly 8k on burps. that box is pretty much a comp box low airspace causes the sub to be peaky which is good for spl but crappy for daily listening. i honestly recommend 15s in your situation or 1 21" warden.

I tried helping you in a pm or two after my first post, but it seems you are looking for an exact replica of another's design and want done for free all the way through. You mentioned you wanted to see ideas, and I think I linked you to my designs that I have done so far, but like i mentioned before, i cannot put something together specific for you until a design is purchased because if you do not like it, which seems to be the trend for you on the thread thus far, i would have some lost time to make up for.
But, i do hope that if you are not willing to purchase a design done properly, that someone on here, along with the others that have given you their time thus far, will be able to come up with something usable for you.
I believe that is why not many are replying to the thread, because each design has been shot down so far, and even my services and no reply back to my pm shows that you are wanting something very specific but do not want to pay for the services that may be needed for you to get something worth using.
That is my thoughts right now with what has been discussed so far.
You have been looking for a specific design idea, and some have helped you very much, but you're still not satisfied, so you obviously are passionate about this being done a certain way, especially when you questioned cubic volume requirements already.
Most of the greater knowledge on the forum is in the form of vendor-ship and business purposes, so if you want to continue your search with us still, the offer still stands with my services and hopefully others will see the thread and chime in as well. Good luck man!
