4 SMALL VENUE SOUND SYSTEMS \nRooms of a size appropriate for stereo or TV entertainment, home theaters, home studios, and recording control rooms do not require massive, highly directional loudspeakers.\n\nHmm. This seems more of a reflection of modern sensibilities when it comes to speaker size than anything having to do with actual performance benefits. Speakers that are highly directional can be used in lively, untreated rooms to great effect. Here is a piece put together by Bill Waslo over at AVS describing just such an approach. On top of the things he mentions, larger speakers tend to be more sensitive, which pays dividends as well: no need for herculean amplification; such speakers in a domestic environment operate low in their SOA, so cone motion and related speaker induced distortion is greatly reduced as compared to more WAF-friendly small speakers, not to mention more available headroom\/dynamic range. In my own experience, big, highly directional speakers, implemented properly, result in some of the most effortless, clear, and natural\/lifelike playback of any approach.\n\nToole is the man, though. Everyone who cares about getting the most out of their rigs should read his book, or at least read this paper very closely. Thanks for posting it, Gene. (Link still broken btw, Jinjuku's works.)\n\n\nMy apologies, but this article by Bill Waslo has absolutely no context and makes incredible 'blanket' statements. What is defined as a 'large speaker'? More than 2 drivers? They certainly do not tend to have easy to drive impedance values, excepting several specific designs (Philharmonic's, for example). \n\nToole is attempting to explain that the sound heard with in a domestic room is dependent upon the spatial and enveloping information provided by early AND late reflections, and that only proper measurements of the room itself will determine the best course of installation.\n\nPlease know that I am learning myself, and am doing my best to absorb the incredible amount of information Toole packs in to his writing. This and my previous response are an attempt to energize the discussion so we can all learn something from his decades of TESTING these principles!
