Greetings,
I am working on a small stereo 3-way unit (boombox I guess). The mid-woofers are 2" in diameter and I'd like to not use a grill. So, in order to protect them a bit I'd like to mount them inside the 1/2" thick baffle. I plan on using either a simple round over, 45 chafmer, or some combination there in(like smoothing the end of the chafmer). I'm going for a wide dispersion pattern an have chosen the 2" as well as TB 1/2" soft dome for the tweeter to minimize beaming. The 2" will be covering(roughly) 150-4000Hz and the tweeter will be mounted as close as practical.

(This was a test box I made to evaluate the design/drivers. please ignore my poor attempt at treating the 2")
Questions: Is it likely that I will lose off axis response in the upper end of the 2"? Will the proximity of the tweeter to the inset in the baffle cause problematic ripple? If so can it be compensated for like baffle step(probably not since it's asymmetric?
My guess is the effects will be hard to predict and pretty subtle. Does anyone have a guess? I know Dave and Earl have done things similar but I haven't heard any of their speakers that do this.
Thanks in advance,
-Matt
