About this model

For all those who have been waiting for the 4" version of the V2.0 speaker, it is now online: And so is the new isobaric subwoofer: Check out the full set of stereo components (and plenty of other stuff): So here it is. Kissing the frog V2.0. This version is a complete redesign, still just as stylish, super cheap, fully printable BUT sounding MUCH better. This back loaded horn Bluetooth speaker uses a 3.3" (as opposed to the original 2 1/2") driver and a USD 1 Bluetooth board and USD 3.5 amplifier. Total cost should be around USD 20. The enclosure with the back loaded horn (please read below if you are not familiar with the concept) is also a complete redesign. However, the concept remains the same. It is like kissing the frog. You kiss that tiny loudspeaker and hope it turns into a prince…
