If you know the workable dimensions of the PE enclosures, that a good look at the dimensional drawings for Alpair drivers on Mark's site. The 7 comes with a separate / optional bezel ring which adds approx 5mm diameter and 1.5mm for depth required for flush fit. I've used them both ways, and can't detect any audible difference.

One more question, does baffle position matter much with the Alpair 7.3? I think I read something about this driver having BSC built in? Can I just center it in the baffle or should I move it towards the edge. My limited experience is with multi-ways where you are trying to account for acoustic centers and diffraction and such.

Centreing on the baffle is not a good idea. It will concentrate the baddle step/diffraction effects.Off setting the driver will spread them out.

Of course on very narrow baffle designs - such as many of the "Ken" family or Pensils for that matter, the option to offset from centre is rather limited

Thanks guys. I was speaking from an up/down perspective. I am quite a layman when it comes to this stuff.

Option 2 would be preferred

Okay, thank you for the input. If I do option 2 that will leave me with some room on the bottom of the baffle. Should I add a port then? I ask because I have some leftover part express adjustable ports laying around. They are 1 3/8" ID and the length can be adjusted from 4 5/16" to 8 5/8".

I know this is kind of evolving a lot but I figure I should try to get the best out of the drivers with what I have available to me. I am sending in the baffles to a CNC shop so I have a day or two to make up my mind on what I should do.

I love audio but I am just a dabbler and I have only designed one speaker system. A two way that I had a lot of help on. Thank you again for all the advice I really appreciate the help.

Did you choose a driver?

Yes, I chose the Alpair 7.3 driver. Also, does it matter how close or far the port is from the driver or the baffle edge?
