They don’t have a wide distribution net in North America but they make some competent speakers.
I owned the Avanti (current version) for a couple months. Overall, they were a good value at the price I paid for them pre-owned. The cabinet finish is second to none. The only complaint I had with these was some cabinet resonance that sometimes distracted from otherwise great performance. I didn’t notice a lack of low octave extension as others have mentioned. In fact that was one of their strengths. They just lacked the 50-100Hz hump that many tower speakers produce. So if one is used to that midbass hump then I can understand why they’d sound lean.
At the retail price of the Avantis, there are better options, like the Spendor D7.2.
