Self-powered speakers: any good?

I believe there are reasons why this technical approach will yield only modest results.

The champ of all self-powered speakers I've ever heard are Event Opal. Event company is mostly oriented for pro audio near-filed studio monitors but Opal has truly high-end performance for the price paid. They're self-powered with over 400 continueous watts each.

If you use passive speakers, you can run really small speaker cable. If you use powered speakers, you have to run an ugly power cord to AND an interconnect. Not sure how active speakers simplify the cabling. I know - I have powered speakers. Plus, wouldn't you have 2 AC cables, one for the SB and one for the speaker plus some short interconnect?

I think powered speaker are better the passive speaker in theorie. I do not own powered speakers. But let me explain. A true powered speaker would have an amp for each unit, unless 2 units take care of the same frequency. But if you have a 3 way speaker a powered speaker would have 3 amps. The great advantage of that is the filter can be made with really good components without it costing the world. Normally filter components like Jantzen caps can cost a lot this is because the have to deal with the high voltage and amperage. But in an active system the filter only has to deal with a line level signal meaning the caps the coils etc can be a lot simpler. So a high quality filter for an active system would if I had to guess cost less then half of what it would cost in a passive system. Also if the manufacturer know what he is doing he can design the amps so that they match what the driver needs.

But sadly there are not that many brands that are willing to take the risk and market active speakers for the consumer market.

The distinction between *powered* speakers and *active* speakers needs clarification. Powered speakers have built-in amps—they do not necessarily have multiple amps and active crossovers. Active speakers utilize active crossovers and an amp for each bandwidth/driver. The amps may be external (active/not powered) or internal (active/powered). The terms powered and active are too often used interchangeably, because most active speakers are powered, and the better powered speakers are active.
