also was wondering how to get the spl charts groundplane for all the designs, i'm new at this and wan't to compare the different designs...

You can take 12dB off a corner loaded response chart.

There's charts for each cab on the sales pages under the burgundy banner at the top of the forums. There are a bunch of charts in the forum pages if you look about some. One thread in particular is called "introducing SPL charts" or something like that, started by Chris Allen. It's kind of hard to find!

The T18 is not listed there...

after a little research i found that corner placement gives extra 6db not 12db as you mention

Having subs next to a wall gets you 6dB of additional sensitivity, and putting them in a corner an extra 12dB.

From the "Rules for Subwoofer placement and stacking" sticky.

Why are you yelling? There's a lot to be said for the occasional use of capital letters and punctuation too.

Keep digging. It's a increase of +12 dB. That or unplug from the matrix for a bit, get an SPL meter, and check it for yourself.
