Direct radiating loudspeakers are a design that were obsolete before they were even envisioned. Popularized with the advent of power/dollar solid state transistor amplifiers giving the illusion of irrelevancy in efficiency allowed manufacturers to cut corners and use small magnets in their drivers which resulted in significant amount of harmonic distortion at typical listening levels and unbearable amounts of harmonic distortion at extreme levels that certain applications demanded. Horn loaded loudspeakers are objectively better than direct radiating loudspeakers in every measurable and relevant domain. Horn loaded loudspeakers have less than a quarter the harmonic distortion at a given input compared to their inferior direct radiating counterparts. A horn is a tube whose cross-section increases exponentially. The narrow end is called the throat and the wide end is called the mouth. The transducer is placed at the throat. When the diaphragm moves near the throat, we have a high pressure with a small amplitude in a small area. As the pressure wave moves towards the mouth, the pressure decreases and the amplitude increases. Excellent natural efficient amplification. For an equivalent SPL, horns require a smaller diaphragm, and since distortion is directly proportional to the size of the diaphragm, a large diaphragm electromechanical transducer (conventional driver) has to move much more than a horned diaphragm in order to create the same SPL (sound pressure level). The larger the excursion, the worse the distortion. So, for a given SPL, a horn loaded system will generate much lower distortion than an electromechanical transducer. ince the diaphragm is smaller, it is lighter and thus it accelerates and decelerates faster. As the excursion of the diaphragm is very small as compared to an electromechanical transducer, the voice coil is much smaller and again, this translates to a lower moving mass and again Mobdro, results in fast transients. Small voice coils also take full advantage of the flux in the pole piece gap. This increases the efficiency of the transducer allowing the amplifier to work with greater ease. Since the amplifier has more headroom and the driver handles peaks and high outputs more efficiently, horns are able to produce much higher SPL’s before they distort. Thus, in the normal operating range, horn designs are more dynamic, have a better transient response, have less distortion, and are easier for an amplifier to drive than direct radiating loudspeakers Kodi.
Why are you still willingly using an inferior transducer?
