I bought Harbeth Monitor 30s to get the low listening fatigue inherent in a cloth dome tweeter. Used as designed in a small control room 10X14 or so---they are quite neutral and indeed perfect. Used in a somewhat larger room they could use a sub and a super tweeter as these frequencies die off at a longer throw. I use mine with two SVS sealed subs. And two 15" Velodyne subs. And a pair of Townshend super ribbon tweeters. They are bi-amped using two Parasound A21s at 250 watts per tweeter/per woofer. I can comfortably cruise at 102 dB when playing loud hard rock like Hendrix at concert levels. But most listening is done at 75 dB to maybe 82 dB. They really shine at low volume. The soundstaging is immense and crystal clear. Truly a "buy it once---keep for life" speaker. And with some judicious use of "add-ons" you can make them into mini Wilson Chronomasters (or whatever Dave called his big setup). Mine are 5 way with individual level control for each driver. Individual aiming for each driver. Yes it takes a great deal of patience to dial out all the mud that comes with subwoofers. And even more time to get the drivers aimed into a coherent point of convergence. Not to mention the usual endless moving of speaker boxes looking for "room lock." But when you get it all locked in---whoa! If I sold these in our Manhattan showroom they would have placed somewhere in the $30,000---$50,000 speaker class. Most "civilians" would not be able to handle the setup duties but that's another issue. In my opinion great sound almost never comes easy. Other than headphones there are so many ways to set things right you can get upgrades all day long just by moving things around in your setup to find better sound. I spent five years on my first build just getting it right. Now it takes only a year or two. My two cents.
