Good Morning, Are there any OB experts lurking about? I've looked up and read all I could, but still haven't been able to answer my question. I thought I had read @ one point, somewhere, that it's advantageous to mount the main driver off-center of the baffle instead of dead in the middle. What I can't seem to remember, or find, is whether you want more baffle between the left and right speakers, or more baffle to the outside of each speaker, or was this just in a pipe dream somewhere, and you want them mounted dead in the center afterall? All constructive comments, ctiticisms, ideas, discussions, and direction are welcome. Thanx to all participants in advance.

Hi gfederys, The way I understand it is you want to breakup the baffle step transition. It is even more imporatnt on an OB speaker than a box speaker because OB speakers don't just transfer halfspace to wholespace but they also transfer from constructive to destructive wavefront operation. That's my penny. Add another for 2 cents worth. Gerry

"The tweeters were going to be be placed @ a 45 degree angle to the main driver towards the center ...." Why would you add this complexity? If the tweeter is firing forward then the design is a little more flexible with respect to placement. I guess I don't see the advantage to firing the tweeter at some angle and then listening off axis.

I don't perceive you're trying to give me a hard time and appreciate your replies. I wish I was better @ explaining so I wasn't wasting YOUR time. Since way back when, I always heard moving the tweeters slightly toward center improved the imaging. Whether this is true or an old MFG.'s tale, I'm not sure. I've been doing some preliminary OB testing on a pair of 18.5 X 18.5 baffles, mounted on speaker stands, so they're about 35" off of the floor. I run a small, powered sub/woofer to augment the low end. Currently the tweeters are mounted on some some small luan pieces on the baffle sides, since I was "hunting" for a tweeter to use. This allowed for quick switching and testing. I like the sound, and want to make some permanent, slightly larger baffles. I'm trying to see, (hear), if there are some ways to tweak these even more, without creating huge, floor standing baffles in the living room. That's why the original question about whether it's more advantageous to have more baffle on the inside or outside of the drivers. I guess another way to do it would be to mount them asymetrically, as you suggested, move them around to see if they sound better a certain way, then add the tweeters later.
