The art of matching a horn to a woofer’s off-axis responseA horn and a woofer may each measure impressively in isolation, yet still produce an uneven loudspeaker when combined. The critical area is the crossover…
Measuring Horn Directivity With A Turntable And MicrophoneHorn directivity describes how evenly a loudspeaker spreads sound as frequency changes. A horn may project high frequencies in a controlled pattern while…
How Phase Plugs Shape High-Frequency Loudspeaker ExtensionIn a compression driver, the phase plug sits between the diaphragm and the throat of the horn. Its passages control how sound leaves the diaphragm, helping…
Why a Compression Driver Needs a Back ChamberA compression driver converts the movement of a small diaphragm into acoustic energy through a narrow throat and horn. Because the diaphragm operates in a…
How Three-Way Horn Systems Improve Stereo ImagingA convincing stereo image depends on more than left and right speaker placement. The loudspeakers must preserve timing, phase, tonal balance and directional…
How to Brace a Large Birch Plywood Cabinet EffectivelyA large loudspeaker cabinet must remain rigid while moving substantial volumes of air. If its panels flex, some amplifier power is converted into cabinet…
How Horn Wall Thickness Shapes Resonant ColourationIn a horn-loaded loudspeaker, the wall is part of the acoustic system rather than a passive enclosure boundary. It supports the flare profile, defines the…
Choosing a Capacitor Type for the High Frequency SectionThe capacitor in a loudspeaker’s high frequency crossover may look like a small, inexpensive component, yet it has a direct role in shaping the treble signal.…
Practical Limits Of Horn-Loaded BassHorn loading can produce exceptional efficiency, dynamic ease and transient impact, but bass horns are governed by uncompromising acoustic physics. A horn does…
Why Some Horns Sound Bright and Others DarkHorn loudspeakers are often described with simple words: bright, forward, warm, dark, lively or relaxed. These terms can be useful, but they do not describe…
