What would be the advantage sonically of putting in four lines of woofers? It would certainly double the cost.

Have you considered a 4 stack box. As the owner got more funding for the project they could add more speakers on top. The x-over would have to be on the outside since adding 4 more drivers would change the sound.

OK(if I may step in here).... But what is the hearing difference and what is it that you are correcting for that you can hear a change for? Since I have a line of 16 3.5 inch woofers connected to a line of 3/4 inch dome tweeters with flanges cut to a c-to-c of about .9 inch, what difference would I hear by adding anther line of 3.5 inchers on the other side of the tweeters? I'd also have to be careful of the distance between the woofers causing potential horizontal comb filter issues.

The Macintosh symetrical design speakers that you alluded to use a design that is similar in the speakers to mine, except that the vertical combing of the tweeters is a nightmare, and the horizontal combing is also a nightmare.

Are you saying that your proposed design using symetrical is better than the McIntosh, or are you just into dicing my design again. (I'm hoping that you have reasons and that its not the second, because then you have violated our agreement and freed me from it also.)
