Every knob, switch and detail is well made and carefully considered. The audio quality is great, which deep bass. The battery life is seemingly great, but there’s only 3 battery bars and no percentage. So it’s not easy to see exactly how much juice is left. It charges quickly through USB C though, so I’m not concerned. I was tempted to buy an old school boombox, but this quickly changed my mind. I have no regrets.

It took the prospect of entertaining friends in a large room to get me to knuckle down and buy a fuller, larger speaker.

But they don't deliver the kind of sound needed for a large, two-story great room with sound-absorbing rugs, upholstery fabrics, and draperies.

Have thought about Tivoli products in the past, and a grad school advisor had a sweet little receiver in his office that I always admired -- which means I was already a sucker for the form factor. I suppose that, in the end, is what sold me.

But here's the thing, we have it placed on a wall where basically it is not really visible! Buy boy can you hear it! It has all the rich, velvety tones I remember from my old ca. 1970's style tower speakers powered by a massive, glowing rack of hardware.
