trying to remember the specs off the top of my head it was something like 2cuft @34ish hz
the Oak is very strong and VERY lightweight- worth the extra $15 In my opinion
After some listening, i was very surprised how flat it sounded throughout the frequencies. It was what i was going for- but turned out even better!
thanks for looking GRIN

What are we looking at here Drew? Give some of the details on your choice of sub and alignment of the enclosure. (It looks like modified BP with vent tuning in one segment and BP in the other chamber?
Comments?

PS Nice workmanship here. Oak laminated plywood is nice. If you really like this design, consider 18mm, 13 ply Baltic Birch on future boxes. This is furniture grade Birch Hardwood and minimal voids. You can stain and finish as desired. Great for HT enclosures with any classic finish desired. (Expensive for sure, but very high quality for the customer that demands the very best)

Hm- no separate chambers here just 2cuft with a nice slot vent GRIN
Hows this for a big build
this oak is getting addicting :-)

Yep, hardwood laminates are nice to work with and lighter than MDF too. They are easier to cut and less wear and tear on carbide cutting tools too.
Hey, what's that roll of material off to the right side of the box? (Looks like carpet padding?)
Finally, what are the specs on these subs and the cf of this box design?

PS We are wrapping up a large venue club install later this month and I'm hoping to get some pics of the system we have been installing. Dale, (my brother) contracted the job and called me in on the project as it's too large for 1 guy to handle alone. It feels good to be part of this large format install as we have not had too many like this one in the past 5 years. (Sure beats the weekly grind of route sales in terms of job satisfaction and seeing great results in short order)
We have 8 JBL Venue Series full range boxes rendered in the ceilings now, (2 zones) and will have 5 subwoofer installed in stage enclosures on the main dance floor as well. (Dual 15" and 18" vented) That's the main house system and the club owners plan to have live band acts a few times a month as well. (Mostly local bands in the area)

actually- no specs for these woofers they have Aura Neo Radial motors and the Basket/soft parts/cone was all assembled by TC Sounds
the box is ~14 cubic feet Net internal with Four 6" round ports
He can tweak his tuning frequency by blocking a port or ports.
4 open ports = 41.x hz
3 open ports = 36.x hz
2 open ports = 29.5 hz
1 open port = 20.9 hx
Swez i'm looking forward to seeing some pictures of that setup- Prosound has its challenges but is very satisfying when completed and that sounds like a good sized setup!
-Drew
**we currently have several plans for cleanly sealing off ports but for now it is tuned at 41hz (just shy of his resonant freq which is ~44hz)
Double Edit **** the under carpet foam stuff is because his Explorer has a "U" shaped floor- the edges of the box are sitting on the floor but the center of the box is as much as 1" off the floor so we will be thickening the center a bit.

you should get a biscut joiner for plywood joints if you keep building like you do. It is a super easy to do joint that doesn't leave any visable markes and is just as strong as screws if not stronger since you can't strip it.
That is a BIIIIIIIIIG OLE BOX mang!
swez on 01/16/2009 17:40:35
True, biscuit joints are very strong and leave no signs of screws to fill later. Norm Abrams uses them all the time on furniture he builds on his PBS shows. He makes it look so easy, but am sure there are some tricks to practice & master before taking it to a real project.

when you get the saw that does the cutting it really is easy. You set how far down the thickness of wood you want to go(if you have a 3/4" thick you set the guid for 1/4-1/2"), and then set the depth that you want to cut into the wood. Put the two pieces of wood together how they will be joined and then mark a line down the two pieces. The saw has a lin on the top of it that you now line up with the line you drew and turn it on and push it in on both pieces. The hardest part is just waiting for it to dry but once it does it is solid, real solid......
I bought one for to finish the mustangs trunks floor and have been dying to use it again... I should be getting the wire accesories today so hopefully the install will continue shortly.
newB on 01/16/2009 20:12:33
thanks guys!! reason i didn't change the jointing was because i ran all the numbers and tuning freq like this- so changing while building would have ment back to the drawing board so next build i will try some unique jointing GRIN

you would not need to change the design at all to use biscuts and they take up no internal airspace. Next time you are at home depot take a look at them and it will make a little more sence but they are great for projects like this in the future.
