Hi,
I've posted here before asking about arrays.
I've got a couple more questions : )
How well do you think a design like Zaph's BAMTM would translate to ART Array configuration?
I know it would only be efficient as the tweeter but ~91dB is OK with me.
The Baffle would be 9" x 95", woofers on the center line with 11" C-T-C and tweeter 1 3/8" off center per John's design.
I think the woofer line will need some attenuation to work with my ~12' listening distance.
I had originally thought going 2.5 way, but now I'm really wondering if John's simple & elegant x-over is really the way to go.
Would it be as simple as bumping up the BSC inductor to match things up?

The tweeters in the drawing are way too far apart. Comb filter distortion would be awful.

Those would be ports
There is just one tweeter, I may move it to the middle.

What frequency is the cross to the tweeter?

It's LR4 @ 1450Hz. I'd use the same conponemts on the tweeter as - R6 the padding resistor

I would put the tweeter at ear level for your primary listening position. I tried to compromise with a 104 dB horn tweeter between sitting and standing, the tweeter can keep up with the mids only at ear level for less than 15 feet.

So the other day I went out and got 8 feet of tweeter, the world is going to be a much better place.
