OK - got it 4" wide PVC caps. May build mine into the little amp!
Hi, which driver did you use? The link shows hundreds! All 8 ohm. My amp is 4, but that should work OK. Also, the container. Can't see what you did there. I'm going to try a very simple experiment. My Roland Micro-Cube has a 5" speaker. A funnel on the front of it (maybe some sound insulation) and a tube!
Driver should be fine. As long as the impedance of the driver is higher than the amp (solid state only, not valve) it just makes it a bit quieter.
