  • TWF6 desktop speaker

    ased on feedback from my Desktop slims post I decided to start a new post and new speaker name. I'm indebted to tomzarbo for his Bantams design on which the TWFs are based.

ID:	1471032The main features being slimmer, taller, and deeper with a larger side mount passive radiator (which I think looks better in the larger space). The front and top will have rounded edges. The volume is about 2 liters. A small plinth will house the electronics (more of that later). The finish will be a real wood veneer all around.

    I experimented first with some 25mm quadrants to check I could successfully get the vener to go around the curves without splitting. I was very pleased with the results.

      Very pleased with the results.
      Used 4mm threaded inserts to fix the speakers.

        Test fit all the drivers fit OK using 4mm cap screws that I will replace with a different style.

        Looking good, how are you powering it with a usb c connector,? You have a 5v amp?

          Yes I am. It will be using USB C with the power delivery function. Meaning I can use a USB C charger that can deliver up to 20 volts. There will be more details on this arrangement soon.

            More progress. Assembly of the cut parts. There is a right and left pair.
            I used 18mm MDF and 25mm MDF quadrant cut to length. I had to route the inside corners of the quadrant so I could fit 15mm batterns inside.
            Everything fitted together well. The qudrant were cut a little longer (1.5mm) so I could sand them back flush with the sides of the case.
            I had to be careful not to cover the threaded inserts with the batterns.
            I used Titebond 5065 for all the joints - never used it before, it's really good, grabs the wood quickly and holds it in place. I didn't need any pins or screws to hold it together.
            built it over full-size Acad drawings which is why there is paper still stuck to the sides in the last picture!

                  From the pic of the spindle and clamps I am guessing it is a SainSmart Genmitsu PROVerXL 4030 CNC Router.

                          I used screw terminals to connect the crossover to the amplifier, and solder terminals from the crossover to the loudspeakers.
