Your thoughts about ATC loudspeakers

Dragon_vibe: in the spirit of sharing information I can add something.  The disclaimer is I am the ATC importer.  

Hans ZImmer's main scoring mixer Alan Meyerson (who works in Hans's building and has worked exclusively for him for a long long time) uses all ATC for all Hans's work.  His previous speakers were B+W, sold off 8- 10 years ago?   I have heard Hans has Quested's in his private studio, but I've never seen them.  

And the fatigue issue, most people who own ATC like them specifically because they do NOT fatigue after long hours.  So I have not ever heard this complaint before you.   Maybe back 20 years ago when ATC used "good at the time" VIFA tweeters, which I admit were harsh compared to what's happening now.  ATC moved over to SEAS models about 20 years ago and now their own ATC dual suspension tweeters (2 years ago).  SO fatigue is something I would hear about as my pro clients work long hours (12-15-18 hrs straight), far longer than a home listener, and fatigue would be a major problem for them.

It is true that ATC passives need a bit more power, the average sensitivity is 85-86dB 1 w/1m. This is because as a driver designer you have a choice: more efficiency, or more low end. ATC does NOT use transmission lines, passive drivers or other devices for serious low end support, as the roll off after such device is severe. But it is true dragon vibe, loudspeakers are an endless series of trade offs and ATC has chosen sealed box type (slow roll off) low end performance over efficiency.

From experience in the pro world, a manufacturer/distributor like me has to play it absolutely straight on forums; never BS, no politics, zero opinion about anyone else's gear that competes with yours and actually try to share what you know that can help others.  Speaking about design values that are hidden, or product features that are misunderstood or clarifying facts is OK if its helpful or relevant to the thread.  But it is not welcome when its clothed in verbal advertising.  So responding to incorrect facts asserted by posters about ATC is OK, but saying its better than XYZ is not OK.  Responding to someone who expresses an opinion that they do not like ATC is not OK.  Any assertion as  manufacturer/distributor of my opinion about ATC or any other brand is not allowed.  Note my posts to dragon_vibe are focused completely on features/values that are not supported with facts, incorrect or misstated.  No response to his opinion, which is 100% OK- because we all have opinions about "what is the best" in all kinds of things.  Its completely OK for someone to like Quested or PMC more, heck the people that import that stuff are my friends!     

This idea that ATC is "not easy to drive" is an opinion, not fact.  The fact is its quite easy to drive for the impedance curve does not drop down low as is the case with large number of passives.  A reasonable amplifier can drive them fine.  A large amplifier can drive them fine too.

ATC makes an 150W/ch amp themselves (P1) - costs $4k. Uses the same design as their 3 way active amp packs.    Unless 4K is a cost no object price point?
