jdkJake, One caution on your rear port size. The 4" hole will be just a little bit wider than the internal back braces are, (4 X 25.4) if your braces are on the narrow side of 100mm the port tube will not fit between the braces especially if you are a little off center with your pilot hole. I'm sure you have thought of this but mine just barely fit.

Have new waveguides with rear pocket removed for easy and clean mounting.. 5 spoken for and 7 remaining $160can/pair. Off to paint soon

Decided to mount the tweeters a new pair tight and fill gap.. I like what I hear. gap or no gap? Can add spacers to experiment..
Either way I definately like the tweeter mounted to the waveguide..

Thanks for the heads up. I noticed it almost immediately after assembling the rear panel. Just after it was too far past the point of compensation.

I have a plan...

Tell us Joel, what did you use to fill the gap? Is that modeling clay?

I used plumbers putty. Had some in the house. The excess carves out nicely

Ah, that makes sense. A good choice as it should "never" dry out nor crack over time.

I look forward to your impressions of a gap vice gapless after an extended listening period.

I ended up using the flared end, or coupling from sch 20 pvc pipe, cut to 2 3/4" long for a port tuning of 33hz.

Default Even the blind squirrel finds a nut once in a while...

You've heard the adage "Better to be lucky than good", well, today I was lucky. VERY lucky.

Routed the holes for the ports. Used a router to start the hole and get a clean surface transition. Finished the job with a 4 inch hole saw.

So, how close to the back stiffeners did I get?

Whew!

Default Holes and more holes...

Front panel holes are finished. Love that Jasper jig!

Anybody need any holes? I am getting quite a collection.
