          Wow! If I had cut them all to 1" like you said, I would have made the top panel thicker to compensate and not made all of those adjustments 156 times.

          That's dedication to a form factor,

            That's a very fair point! Although, after investing 12-14 hours to cut and route each one of the staves, taking 30 minutes to run them all through the planer again didn't seem like an overly arduous task. Although I was a little afraid that after investing that much time in them, the planer was going to ruin them either via tear-out or planer snipe - luckily it was taking off such a small amount that none of them were ruined in the process.

            Cheers!

              Here are a few updated pictures of this project. I got the tops/bottoms on, all edges routed, and most of the sanding done. I ended up going with a much smaller round-over than I had originally planned. After cutting some test pieces, I decided I liked the aesthetic of the smaller round over better.

              Cheers!

                      From the top it looks like the coolest pencil sharpener ever

                        Really cool aesthetic. I'd argue for more edge treatment (round OR Bevel) on the front- shame to leave that little extra performance on the table with such a substantial build, but in any case, they will obviously have a great look to them, you've done a lot of fine work.

                          Thanks for the positive feedback everyone! This has been a really fun build so far.

                          With regard to the baffles... those are next on the list. I'm planning to make removable front and back baffles,

                          Regarding the round-over. I know that a larger round-over would help with edge-defraction, but how much of a difference would be expected between a 1/4" round over and say 1/2" or 3/4" round over?

                          Cheers!

                            3/4" is pretty substantially more effective. it's the difference between helping in the midrange (2khz) and only in the very high treble (10khz), due to the way wavefronts "wrap" around it at different angles of incidence.

                              How did you go about sanding the stack of staves, especially the inward curve? Did you have any issues in lining up the stack of staves. I have a stacked project half way in the works, but the line up is horrible.... I am dreading the many hours of sanding, once I manage to glue them up

                                This a great question, and hopefully others can learn from my mistakes.

                                The first stacked project that I made was drawer fronts for a night stand (linked below). I followed basically the same process that was used for the speakers: cut blanks > rough cut blanks on band saw > finish cut blanks with a router flush trim bit, but I made two major mistakes during the process:The drawer fronts may look smooth, but I had to do some extreme sanding to hide the misalignments.

                                With that said, here are a few things that I did differently when making the staves for the speakers:
