Thanks.
it's really not necessary to do it that way, and simply installing the spacer would have been much easier.
I was concerned about increasing the volume of the compression chamber, but with some reading on the forum, I discovered that using the spacer does nothing toward changing the response of the mid horn.
Also, If you think about it, routing a round groove the way I did also increases the chamber volume, so why not just use the spacer?
Sometimes I just can't help but do things the hard way lol.
The one advantage is it helped keep the cabinet enclosure on the back of the horn a bit further away from the edges of the woofer magnet.
I'm getting closer to being ready to pull the waveguides and woofers out of my 4pi's for using to complete the 7's,
but the thought of pulling them apart makes me a bit sad.
