I'm not getting into any arguments here, but I am surprised as to why actives aren't more popular. I can understand people nowadays want a solution that involves less boxes. In fact, the likes of soundbars, iPod docks, and mini systems proves that. As someone has already mentioned though, I doubt very much conventional hi-fi systems are going to die out, contrary to the beliefs of the few that do their best to promote actives. Actives (albeit in their more basic form) have been around for many decades, but for domestic use, passive was the chosen route at sme point for the majority, and still is. There are plenty of powered speakers on the market that are quite popular with students and youngsters nowadays, and if they grow up and look for an easy transition, they may well be looking at something like the products AVI are producing, but they need to be in a large number of dealers around the country. You need widespread coverage in order for people to see the product, play with the product, and buy it. Some of the most successful brands in audio and AV today have relied heavily on marketing to get the brand and product across, and they've been ready to grow with that steady increase for demand. Waiting for conventional separates and dealers to die out isn't the way to gain market share - promotion, promotion, promotion. And not the kind we see on forums.
Having said that, when Ken Kreisel designed the first active subwoofer in the early 70's. He wasn't to know that it would come into its own in the 90's for home theatre use. This is what AVI needs - but I can't see that happening for stereo speakers.
The other issue AVI may have is that now more manufacturers are starting to come onboard with active speakers, their market share might be eaten into as people who start looking at active speakers will "go with what they know". But who knows? Maybe one day soon the active thing will just suddenly explode. The future for electronics is unpredictable.
I did have a structure for this post, but I want to settle down and watch Donnie Darko, so I've rushed it a little and it has become messy. Hopefully a few points got across though
