First, stack the woofers like this .. less cancellation if they are aligned with mic better.

Some good reading .. some people don't use this theory but I have seen it work

Also, what is ur imp at freq? do u have a clamp meter?

Here is a spreadsheet i put together for testing

ok ya that makes sens and ya i have a clamp meter and i dont remember what the freq was havent done that in the last few runs

do you have to have that back 90 degree angle in there? if so....try covering it with a back angle.i dont know what degree but maybe a 35? im not sure. testing a lot of them would work well. if you do it try to double the wood on the angle so its strong

 

[hunterw 10+ year member]

and also. stack the woofers offset. like diagonal. and put a divider inbetween them. say 6-7 in deep. and fix that resin job, jesus LOL. open that port up. triple the wood for youor port piece. and the back wall when you rebuild. run bracing through the box too. threaded rod or something like 2x4s

the whole box is double 3-4 wood in cluding the port, and i was thinking of ressioning the rest of the box we was using it to make shure the seams were sealed up good. that angle is a direct 90

Rebuild it. Lol I even gave you pictures you can copy. Stack your 2 15s on the passenger side as close to the side wall as possible and make your port on the drivers side like someone has shown with a pic.

ok will have to try thanks for the input

 

[genxx 10+ year member]

Just an update. We are trying a few tricks you guys mentioned on the current set-up to try and get the last of whatever we can out of it. Aho77 was able to improve his numbers all season until we hit this roadblock.

He is planning on keeping the current set-up to make in through USACi finals this year.

Go back and apply stuff we are learning now to imrpove the box design and install for next year.

I would like to thank all you guys that are trying to help out with input and ideas. It is appreciated.

Please keep the input and ideas coming.

We will let you guys know if we were able to get anything else out of it or not.

Well got a text message with pic this morning.

Aho77 installed a 10inch divider between subs, 45deg. the other corner and finished fixing the resin on the box.

He did not have a chance to run it in the kick at 2am worried about some calling the popo.

He did run a quick port test on music did a 163.1 which is a 3db improvement. Before mods you guys recommended it was doing a 160.1 in the port.

Later will mete it in the kicks to see if the port being louder leads to a higher kick number.

Thanks again guys.
