Are the CAD files to scale? Is it possible to get a copy of them? Thanks!
Yes they are to scale. No it isn't possible to get a copy. I no longer have them. The only available document is the Google 3d conversion someone made. It is linked in this thread.Are the CAD files to scale? Is it possible to get a copy of them? Thanks!
Works fine. Not as good of a driver, but still pretty good.Does this works well with the kappa perfect 12.1? the one that doesn't have the variable Q.

You could use a bash amp. www.oaudio.com or parts-express.com.I want to build this subwoofer, but I am on a budget (really lol), it looks like the ep2500 have a lot of power for just one of this, is there another amp that I could use with a better price tag?
There's plenty of amps at partsexpress, wich one do you recommend for this driver, one that doesn't have too much power but just the enough to drive it fine.You could use a bash amp. www.oaudio.com or parts-express.com.
O-Audio 500w You'd need an amp for each driver.There's plenty of amps at partsexpress, wich one do you recommend for this driver, one that doesn't have too much power but just the enough to drive it fine.

because it's not necessary.Back from the dead....
Is there any reason that the main internal brace doesnt have any holes in it? It seems like most DIY boxes the builder put holes in the braces but this one doesnt. If you did put holes in it what would be the outcome?
There is no point in holes since you need to glue the rockwool to the brace. I would suggest against it.because it's not necessary.
the spaces above and below the brace are enough to let the air flow freely
you can put holes it in if you want without negative outcome except for:
1) more work
2) less strong (but a wee bit lighter) than that one big piece of wood
3) make sure not to punch holes in the port tunnel walls

The upper band might be crossover issues. You might play around with the crossover to see if that helps. Overall that's crazy good.Just speaking from experience here...
I built this box and flush mounted the driver. Because of flush mounting the driver butted up against the 4" of rockwool.
I drilled 4" holes, can't remember how many but several, in the board and put 2" of rockwool on front of the board, and 2" behind the board so that the vent on the subwoofer could breath. I wanted to keep the 4" of rockwool behind the driver and that is how I figured to do it.

Performance wise I believe it had zero impact on anything audible. My sub still had steller performance. Here is an in room frequency response graph using REW. As you can see the subwoofer had very strong output down low.

and it sounded quite smooth through out it's frequency band, except some serious room nodes.
Like mike c said though, definitely more work.
Maybe.... How much shipped to 33122?I have two kappas perfect 12VQ new in box, anybody interested in one???
