I went a little further with the Minirig 3’s I bought a few months ago and added a Minirig Sub 3 for a 2.1 stereo system. The only downside is if you add a sub, you have to connect it via a 3.5mm wire. There is no way to have the whole system wireless.
I agree that the pairing process is very quirky. In theory the Minirig App should make it easier, but in fact the app is almost useless. A few of the app functions work… but you are supposed to be able to link two of the Minirigs together so they will always boot up already paired, but this simply doesn’t work (at least IME, YMMV). I really wish they would get all of the bugs worked out with their app.
Once you get the hang of manually getting them paired for stereo and adding the sub into the mix, the sound is great. They even work decent for playing outdoors. They have a low gain and high gain setting, so you can adjust them accordingly depending upon your location and needs.
There is an odd British fellow named Alan Ross (Alan Ross Reviews) who has put out several YouTube videos on various combinations of the Minirigs which even include sound demos. If you have any interest in these speakers, his videos may be worth the time checking out.
A new (revised) competitor for the Minirig 3’s has just been released by Bang & Olufsen. It’s their Beosound A1 2nd Generation. At $250 USD a piece, they better sound really good if you were to pick up a pair for bluetooth stereo. I don’t know much about B&O products, other than they are quite pricey. But just for fun I would love to hear the new A1’s in a sound comparison to the Minirig 3’s. If they pair together seamlessly and sound even better they may be worth the premium price tag.
