Thanks, but in the interest of staying with the OP’s topic, I’m NOT discussing the use of external crossovers and amps.

Not only was that not mentioned in his post, but the use of active crossovers and external amps in the home is probably the very rarest of beasts. I’ll happily engage in that topic elsewhere.

And what exactly is the interest of the OP in this regard going by his threat opener? He only says the following:

I Was Considering Active, Then I Watched This ...

No specific implementation of active configuration is mentioned, so that holds every route open here, as long as it’s active. Moreover, the threat is over 3 years old (with an activity pause almost as long) - the OP might have gotten along since then, and so what we’re venturing into at this point, for as long as we’re continuing with active as a general topic that isn’t at odds with the OP, I’d say it’s all safe to go.

But really, you’re no admin of this threat (or even if you are, I’m within the confines of the OP) nor the OP poster, so loosen up on specifying what we can or cannot discuss. It seems to me it’s about what YOU would like the specific context (of active configuration) of this threat to be about, rather than the OP. My take: chart off in any direction of active as you see fit and let others do the same, and if the OP has a problem with that, he can chime in.

With regard to the link of his: Steve’s rant on active goes on to state - 2:15 into the video - that the Parasound A21 power amp (as an example) doesn’t fit into most any speaker, and you’d believe he really wanted it to if it weren’t so darn impractical. That way of thinking of his tells me Steve is not even considering that the A21 doesn’t have to fit into a speaker (for it to still be active), so my deduction is that ’active’ to him is defined as a bundled approach, and he’s stuck with that. Really, he doesn’t get it.

Take the ATC SCM300 Pro ASL. It’s an actively configured speaker through and through, yet the amps and electronic crossover are outboard, most likely due to the power requirements of the amps and the physical size this would necessitate. The JBL M2’s - another example. Sanders Sound as well. Even if there are only a few such examples of active, it doesn’t make it conspicuous or other - it’s just outboard.

Where it gets more hairy is setting the DSP filter parameters by oneself, and I’m assuming this goes for your DIY center channel as well? You think the OP initially considered a DIY approach of active like that? Maybe he didn’t even consider outboard active, and that’s where I feel correcting Steve in his video rant is appropriate. It only broadens the opportunities while potentially raising the bar even further.

I’m just saying that coming to some universal truth about the desirability of an active vs. passive speaker in the home is never going to happen.

At this point it seems the overall purpose is merely to have audiophiles accept active configuration as a viable approach next to passive, and get rid of some of the misconceptions here. Once there active can really begin its ascent into wider use (and configurations) in the domestic milieus.

I can say this, we get more calls about active now (regarding info on ATC as we are the importer) than ever before.  I think this bias against active is beginning to change.  Not that passive will go away, but some are beginning to want to scale down (a turntable/streamer, preamp and active speakers is nice simple system that has high WAF). or hear a pair of actives and like them better.

One reason active is better is the short speaker wire from amp to speaker and long I/C from pre to amp. I was told by one cable mfg this is the preferred way to do things. 

Brad,

Are the amplifiers different between the SE versions and the classic versions of active ATC speakers?  If so, what would be the sonic gains?

Does ATC makes actives with amplifiers external to the speaker enclosure?  

Thank you.

HI @glai 

The SE uses all discrete amplifers, the best [sounding] amplifiers ATC makes.  More esolution, finer detials are more clear, etc.  

Yes ATC has made external amp actives for a long time.  IN the pro side they make the  SCM200 and 300- both use an external 3 channel power amp for each speaker.  There are tower versions of these for home using a different tweeter (ATC vs the AUdax super high power one for pro) but it still uses the P4 external amp/crossover package liek the pro version.  Tjhese sound great but use fans to keep cool so not the best for living rooms, bu better suited to a machine room where they can be remoted.  RIght now they make a 150LE that uses a 3 channel, passive cooled P6, with intergrated crossover, so this is an "external active" solution that functions the same as our internal active set ups.
