      You're telling me. I am amazed at the low end that comes out of these little speakers. The 2x8w amp is more than adequate and provides very adequate room filling volume. I did try the speakers without the cross overs just to see what it would sound like. It was a little rough. After adding the crossovers everything smoothed out.

      The one thing I wish it had was a tad bit more high end. I don't know if adding a single tweeter or two would work, but I would not even know where to begin with that. I know the goal was a to keep this design simple. If you ever decide you would like to add a tweeter or 2, I would be happy to supply the drivers and anything else you would need.

      Thanks again for the great design. My dad cannot stop listening to the mahogany box I made him. He appreciates it just as much as I do.

        I really like the look of these. Lord knows I don't need more speakers for my house, but since these are so cool, I've decided to build a few similar looking boom-boxes for Christmas presents. I'll likely start a thread for mine after I do some more planning. Thanks for the inspiration.

          I think that is great! Can't wait to see the thread. I have made a newer version with the OS speaker setup covered to look like a vintage early 60's Fender bass amp with period correct hardware and volume knob. I am waiting on a digital volume control from Sure to replace the analog unit in the box above. I have found the Sure branded electronics to be rock solid and darn good quality. They are small and day to work with and down require massive AC/DC adapters.

            Question in the Sprite design.

            How does making the depth 9 5/8th change things when Paul's design states 10. I may have made the box slightly too short.


            Also can you got a little more in depth on the wiring of the panels.

              With that depth change you are about -4.4% smaller that the original design, losing .006 cu ft. It may not sound like a lot but it is a small enclosure. I believe rule of thumb is to stay within + or - 10%. Someone please correct me if I am wrong. All you can do is give it a try and experiment with the polyfill.

              As far as the wiring goes that is hard to lay out unless you have a specific question. The crossovers are mounted on 1/4" MDF, and the amp gets 12v. Other than that is is pretty straight forward.

                That's my creed.

                  Looks absolutely amazing. Would be a cool thing to build my brother for Christmas this year.

                    ND65's? Or ND91's?

                      ND-91s. The enclosure matches the specs of the Sprite just a different shape

                        Great work Gordy. I love the guitar amp look. May have to incorporate some of that in my next.

                          Gordy,

                          This is another example of a well thought out project. Thanks for the detailed tutorial and the inspiration. I am almost ready to start my own journey and excited to post how it turns out. Going to do a portable blue-tooth design that is somewhere inbetween the Roxster and Madeleine. Unfortunately, you have set the bar very high here!

                            Gordy,
                            Do you have measurements available for your Roxster? Did I miss it somewhere? This is just the thing I have been looking to build, measurements would be super useful!
