Tang Band
W4-1320 4" Bamboo full range driver
This is an interesting driver because it is very
wide range (I feel it needs a tweeter for best performance but that
is my personal preference). It has a relaxing sound that works well
with both solid state and tube amplification. It also works great
with the digital Sonic Impact amp. Bass sounds fuller than its
specifications suggest. It is very easy to design a simple ported
box for this driver but it also sounds very good in sealed boxes.

Interesting
looking cone! Lots scrunched up in there.

.22 cubic foot or just
under 7 liter box. Port 2" x 5" long. Box lightly stuffed with wool. Piezo on back connected to .33 uf capacitor + 20 ohm resistor
across. Everything sounds right. Bass is tuneful and treble has
typical piezo fizz but I enjoy the liveliness of piezo's! This
driver sounds extended but needs a tweeter (pick your poison) to
provide more realistic treble. Small rooms don't require sub but
larger rooms do. This is an elegant speaker, both in looks and
sound.






4" Bamboo next to 3"
aluminum TB. They sound similar. Bamboo is more dynamic, warmer and
more natural sounding to my ears.
