Firstly, awesome build. I'm getting a little scared to build my own. The wife might freak.

Second, response seems to fall off a cliff at 15 Hz, which seems a bit strange. Looks like a ported box...

Re: Christmas Build

I like your idea but I would not use MDF. I would implement a sort of truss out of 2x4's. MDF is wimpy stuff.

Re: Christmas Build

Looks like an impressive baffle for an impressive looking line array!

I've thought a bit about decoupling and was thinking about attempting something with my upcoming build. I searched around a...

7 boards? 8? What is the master plan here. Should be a pretty stout baffle if those get coupled together well. Gluing right?

I have the 1124 but would have bought the MiniDSP if it were available at the time. That said, I have to be careful that I don't clip the input on it with my receiver. It's also got a push button...

Re: Christmas Build

For the miniDSP problem, I believe there is a jumper that can be moved to change input sensitivity.

Re: Christmas Build

Hmm. actually I was thinking something different. Imagine a sealed box that sits just below your screen in the HT room with the 4 subs in an array just like you wanted it. That box would have only 5...

So wait, staggered studs are 6" on center or they are 2x6?

How about building a box below the screen that allows you to mount all four drivers in your room without cutting concrete? The box would...

Re: Christmas Build

I prefer the front mount. I wouldn't want to see the wires unless you did something really fancy like copper tubing (saw pictures of a sub someone did once like this and it looked really cool, of...

The reason WinISD has problems (in many cases) is due to round-off that leads to numerical inconsistency with some of the formulas. That's why it is best to enter the most important ones and let the...

There is potentially a 3dB loss from not having them colocated I think. I would rather have the modal smoothing effects I think.

I'm not aware of any negative effects of facing the drivers how you...

In my build I'm planning on similar config but with 2 manifolds. Each one with 2 opposed IB 18s. They will be flanking the mains. Makes it a little easier to get the opening required.

If you could at least make opening the size of one side of the manifold it would be a lot better
