I agree about the PMC marketing. Actually the bass alignment they brand as ATL, or at least something effectively similar, is used by other manufacturers. You can see this if you look at Stereophile's tests and see that it's not only PMC where the port output is broadband as depicted in the section on PMC of Newell and Holland's loudspeakers book.I respect PMC speakers and I understand why many people love them.
I dislike how PMC market the transmission line (TL) thing. It's fair to say they're not true TLs i.e for bass roll-off and transient response. The theory is a true TL acts like a sealed box, but in practice I don't know of any speaker sold as a TL like that.
IB1S FR has extended bass. But it drops off quickly, not like a sealed box - you can see the sealed, tiny SCM7 even puts out more at 20Hz.

From the other end of the stick, your active ATCs act better than a typical ported reflex. Like some Tannoys, the roll-off and transient response is between classic reflex and sealed box.
Of course you could demo, enjoy, prefer etc. PMCs for other reasons.
Just goes to show that having boatloads of money doesn’t endow you with taste, or class.O I don’t know, it think I wouldn’t mind looking at these in this room on a daily basis
PMC impedance measurements that I have seen, show the double hump of a reflex port, so I assume that they are actually resistive loaded reflex, like TDL RTLs were. Truer TLs have a fairly flat and single humped curve. My TDL T-Line 3s have this.I agree about the PMC marketing.

I agree. Good speakers can be expensive but don’t have to be gigantic and ugly.
I don’t see the point in the multi driver arrays or what advantage they bring? Surely it makes for a very complex crossover & lots of unnecessary wiring, the height is also utterly ridiculous.

Actually the reason I wish to try the PMCs is more intellectual curiosity than any intention to buy. That PMC's ATL is really a port with a particular tuning looks right to me. I have read a lot of generalizations about reflex ports that don't always correspond to what I hear. Although I have now retired I refuse to turn off my brain and getting a better understanding of loudspeakers has been a "project".
And yes, re ATCs. There are something like five orthodox ways of solving the reflex port equation and they can differ quite a lot. That's one of the reasons I think the generalizations aren't universally true. However there are lots of people here with real experience of loudspeaker building and I'm wary I might be writing rubbish.
I’m with you on that… I actually only have my daughter with me, and she’s a music lover but not much of a social listener as myself, she has her own system, and headphones and tends to listen alone… I however am a social listener, I’ve friends and family outside of my household who are music lovers, and we quite regularly have get togethers where we take turns picking an album, a system we can all enjoy at the same time is definitely a plus. My main system is good at that, you lose the pin point imaging if you’re sat off to the side, but it still sounds tonally even and entertaining. Further to that, my main system (well both systems) are also used for TV/movie sound so a good off axis response is pretty important.I have no idea. Something where my whole family of four can enjoy the same experience. That rules out anything too directional. Tried omni and they spray too much against the walls of my small room. Next thing up is line array with restricted vertical dispersion but super horizontal loveliness.
Musical appreciation is something that should always be done with others not on your own with your head in a vice.

As ever with this sort of thing it all comes down to taste/context, and I’ve never personally liked huge systems in huge rooms as everything I’ve heard just sounds like a PA system to some degree.
