My understanding is that the Venere’s were SF’s misstep into manufacturing their entry level speakers in China. I don’t know, but price point and the China issue may have had something to do with your poor experience. I believe they have taken everything back in house in Italy after that manufacturing experiment produced less than desirable results etc.
I wouldn’t say my experience with the Venere 2.5s was poor, it’s just that they were compromised in build quality and cabinet resonances. While build quality may have improved, I’m still very skeptical that the Sonetto’s cabinets don’t resonate and affect the sound as they’re of a similar size/weight to the 2.5s I had in my system. Back then the contention was that the unique lute shape counteracted the lack of inert mass. Well, not in my experience and I’d bet it’s still an issue with the Sonettos because physics is physics. SF makes some of the best speakers on the market, but they’ve clearly struggled trying to build good “entry-level” speakers and I personally wouldn’t gamble that they’ve fully figured it out this time either. To me, the Usher Mini Twos I mentioned earlier are more established, are built much better, offer a tweeter the Sonettos can’t touch and can actually produce bass while looking beautiful doing it at about the same price. No brainer to me, but if you’re smitten with the Sonettos then go for it.
