The gap is so a bass port can vent from the top pipe. There are more drawings of the speakers that show the port, but I only posted a few pages of the print.

We are not sure if this is a good idea or not and plan to do some testing to see if it helps. I'm kinda hoping it sounds better with out the port because it would be easier to build.

I originally planed to make these parts on my manual lathe which would have been tough to make two identical ones, but thankfully I got my CNC lathe running and figured out a way to mount the parts on it.

Dale,

Wasn't sure without a clearer picture. Back in the 80s I dabbled in building speakers. Had a guy who built them as side business for clubs and such teach me a bit. Honestly, I don't remember a whole lot. I do have a book somewhere around here: Loudspeaker Design Cookbook. I have a much older version... has some equations on calculating volume etc of the box. Interesting stuff. You might want to suggest for him to pick up a copy, the older versions are a bit cheaper.

I have been planning a small speaker setup (in my head) for the new place (along with a tube amp). One of these days I will get towards building them.

Found some on-line calculators. Not sure how accurate they are:

DIY Audio and Home Theater Shack.

They have an interesting Tutorial as well.

It only gets crazier.

Yeah, I got him that book for Christmas last year! It's amazing how much science goes into building a speaker.
Im hoping to build some more speakers in my future too, but just don't have the time right now. I also have PCB boards for two different amps to build, but don't have the time or money to work on them. Hopefully I can have one of them up and running by next year. A tube amp would be really cool, but they seem to be expensive to build and I don't know anything about tubes.

I have some info on an inexpensive tube amp somewhere. I will find it for you... When I say inexpensive, I mean the tube cost. Somebody designed a decent amp around a cheaper tube. Just have to find the info. I have a couple of the tubes (6EM7), you can get em pretty cheap on ebay.

I ended up building a small practice amp for my brother in-law along with an effects pedal and got hooked.

Great book for a gift for your nephew.
