The is the third in a series of FAQs ("Frequently-Asked Questions") , the first of which was the Klipsch serial number FAQ, and the second is the Active Bi-amping/Triamping FAQ. This thread discusses corner-horn loudspeaker imaging, in particular, how to achieve outstanding imaging, and typically encountered issues with corner horn imaging. Klipsch currently makes two corner-horn designs (i.e., the Klipschorn and the Klipschorn Jubilee), and has made smaller corner-horn speakers in the past (e.g., the Shorthorn series). Other manufacturers make or have made corner horn speakers (e.g., Voight, ElectroVoice, JBL, and smaller companies like Pi and Decware, etc.). "Can I get Outstanding Imaging from a Corner-Horn Speaker?" Yes. Good corner-horn imaging can be "unsurpassed". "What are the Advantages of Corner Horns?" A corner horn is designed to be used in a corner of a room or outside structure (such as an outdoor stage backstop). While this type of speaker is not new, it is not often seen in today's audiophile circles. Many misconceptions about corner horn potential performance and proper setup exist: 1) They provide dramatically lower bass distortion, in particular, modulation distortion, than non-corner-loaded loudspeakers(modulation distortion in loudspeakers ). Bass modulation distortion has been found to be quite audible (Subjective_Effects.pdf). 2) They provide much greater low frequency dynamic range without resultant woofer compression or other forms of distortion, which limits achievable sound reproduction fidelity of other types of speakers 3) They have the potential to achieve full range controlled directivity in-room if designed/produced carefully "What are the Disadvantages of Corner Horns?" 1) They require good room corners to fully achieve their lf response, or a large footprint in order to accommodate "false corners" 2) They are physically large and heavy speakers if they are to reproduce all needed low frequencies (e.g., piano, organ, string bass, etc.) 3) They require amplifiers of high quality for the critical "first watt" of input power to achieve full potential 4) They require careful placement of objects and/or acoustic treatments in-room in order achieve their full imaging potential "What is Different About Corner-Horn Imaging?" Corner-horn imaging performance is a strong function of the room they're in, i.e., 1) The room's absolute and relative dimensions, its shape (including the ceiling), and the uniformity of the walls next to the Khorns (i.e., front and side walls near the speakers) 2) The placement of the speakers within that room on the boundary (e.g., tailpiece-to-corner fit to seal the two mouths of the bass bins, the length of the corner extensions from the bass bin on front and side walls, and whether there are any intrusions into the room by bricks and other architectural details (yes, brick fireplaces and mantles can significantly affect imaging...) 3) The absence of near-field furniture or equipment that reflect acoustic energy, and 4) The judicious use of acoustic treatments (...it usually doesn't take very much, but it usually takes some). 5) The quality of the "first watt" of amplifier power driving them
