Oooohhh Aaaaahhh....

Building starts. I built both at the same time so that I could make the same mistakes on both cabs at the same time, such as the baffle that I cut the hole wrong on for both cabs and had to re-do.

On a side note, this turned out to be the worst batch of Auraco I've ever used. Lots of warping.





The sides are finally glued on. Loaded up one of them to test it out.

My least favorite part of filling holes and gaps before the Duratex goes on.



Almost finished.

Here I am utilizing them in back massage mode.

Some of my initial impressions:
They're significantly louder than the T39's that I built 3 or 4 years ago. I tested them in my 30'x56' basement and was able to get crazy amounts of vision blurring bass at ~40 volts that I don't recall getting with the T39's. They're also significantly larger than the T39's. On paper it doesn't sound like a big difference, but holy cow these are big subwoofers. Everyone that sees them makes a remark about how large they are.
These are going to be installed at a church and we're still messing around with proper placement. Although they don't have quite the oomph that they did in my smaller basement, they still sound miles better than the single EAW SB150 they replaced. We got the most even response when paired together right in the middle of the stage (as pictured above), but they unfortunately can't go there because it's one of the few stage entrances. I think our best option (of what we have available) will be grouped together on one of the sides, but it was late last night and we didn't get a chance to test all of our options. There are only a handful of spots that they can physically go, so we'll have to make the best of the situation.
Overall, I'm impressed and highly recommend T48's if you have the space for them.
