  • Bluetooth WineBox with new PE plate amp and TB W3-881 drivers

    Just a quick project using a wine box and the new PE bluetooth plate amp.

    Total volume of the enclosure is about 0.13 cubic feet. two ports, each 1" x 3.5" tunes it to about 85 to 90 Hz. Drivers are the Tang Band W3-881 using a simple contour filter consisting of a 0.75 mH inductor and a 4.7 Ohm resistor in parallel on the + speaker leads

    I modified the PE plate amp by removing the spring terminals for the second speaker and closing the gap. I will re-use that spring terminal set for a second set of speakers using another identical plate amp -- that way the second speaker will have a terminal that will match the one on the amp.

    I was eyeing these up on sale, but assumed there's little to no low end.* You've worked with these tb-w3, ps95, pc83, fe83, and probably others. Which do you think are best bang for the buck.*

        I've used all mentioned, and are great with a tweeter. I'm not looking for thump, just a nice balanced sound. Thanks

          PS95-8 or Vifa TC9 are my choices for best overall. RS100 also up there.
