I like the idea of active speakers, I have used them in the past but not with the amps built in.
On the pro sound side, you can load the programming into the DSP of the amplifiers and press on. My XTi amplifier has that ability and I can do 14 bands of parametric EQ, crossover points, different crossover filters, adjustable delay and adjustable limiters. If my amplifier gets damaged from being stupid, lightning strikes or just age--get another amp with rinse and repeat.
My issue with built-in amps with mystery processing is the speakers only last as long as the amplifier does and the company decides to support it. A year past support cuts off, the speakers should be prepared to be replaced completely.
Basically, you have to believe the amplifiers were designed correctly, all the parts inside are proper spec'd and actual real parts and the company will support service to your amplifier long after that model has been replaced, upgraded or whatever. We are talking audio companies here though, in reality long term support has never been in their game plans.
The juice is not worth the squeeze, consumer speakers are not professional ones but I'm sure the more expensive speakers could be produced with DSP files which allows amplifier flexibility to change as needs change. It won't happen, audio companies have enough problems trying to agree on anything, won't publish standard specifications and fight creating standards yet attempting to creating something to allow cross pollination across different brands.
Look inside that Elac speaker, look at the parts used for the amplifiers--I'm sure they are all premium parts designed to operate at least 20 years!
The Andy Jones stuff is all made in China so generic parts seem to be the standard...I would not put much trust past 10 years on that stuff. Not a big deal if you consider speakers disposable, works for computer desk speakers, blutooth and boomboxes--but when you start blowing serious cash on speakers or, use 7 to 11 of them for HT...maintenance must be looked at. The other thing is when running HT, now you have to provide power strung all over your room. I prefer to have my amps in one location so no worries about ground loops and hum from running long cable runs.
The only speakers I'd get that were fully active would actually offer something I can't get with DSP amplifiers. Samsung with their predictive distortion technology would be one, just having wireless or EQ/crossover points is not worth it to me. Way, way too many downsides with very short attention spans from audio manufactuers when it comes down to "old models".
For now, I'm building my HT with passive speakers (including passive subs) my DSP amps can be programmed for the subs to maximize performance and located where I want the power lines. No way in hell will I use 11 active speakers, I refuse to run power outlets in the ceiling, proper locations for the surrounds and all that mess. In the real world, I use a living room and my wife usually reconfigures it every 5 years. No worries...run extension cords when I reconfigure the HT system...uuuuhhhh...no.
So I view the Elac, KEFs and that sort of thing as medium term speakers at most. It is a niche' that has customers and they do have uses. Since I use speakers for many years, they go from the living room to bedrooms, the garage and so on. Active speakers would be great as long as the amp/processing can be outboard of the speakers themselves. Not hard to do, pro sound has been doing it for many years but it goes against the consumption model of consumer audio. They are fine for two channel systems, desktop systems and that sort of thing but for multi-channel, I'll pass. The juice is not worth the squeeze.
Technically, in 8 years you could fix your lightning damaged powered speaker by converting it to a box with outboard amps with DSP, always an option if you really LOVE the sound of the speaker. All it takes is for the original manufactuer to still be around, open to giving you the proper settings and off you go. Looking at the track record of many companies, I would not count on that.
Just a pondering of mine--as always YMMV.
