a horn loaded speaker achieves its high sensitivity by directing more sound forward and less to the Actually the horn kinda sorta lets the driver "grab the air" better so more of the energy transfers from the driver into the air as sound. They are beating the room reflections to you.Ĭlick to expand.ANY truth? Well, SOME, but not much. People like near field listening because all the sound waves that hit your ears first are coming from your speakers. Of course this introduces new problems with distortion which is why horned loudspeakers are harder to design than ordinary dynamic speakers. The horn now amplifies and directs your voice allowing you to do the same amount of work while being heard further away. Take an old bullhorn talk at a normal volume and then put the bullhorn to your mouth while talking. Two things to put this in perspective that are often discussed are old fashioned bullhorns and near field listening. A driver coupled to a horn has to move less to create the same sound volume then a driver not coupled to a horn. And yes basically the horn increases efficiency by channeling and amplifying the sound. All speakers produce some sound in all directions though some designs very minimally. If you can't budget for a true 500WPC amp and all sorts of room treatment, horn loaded speakers may be an excellent choice.Īctually it's more right then wrong. Obviously, there may be exceptions to this generality, but the point is its a decent thing to keep in mind when comparing speakers. It is a tradeoff, but because of the relatively low wasted power in horn loaded tweeters and the less effect a bad listening enviroment has on them, they do remain quite popular. This is not a bad thing if extreme room renovation is not a possibility.īecause the horn loaded speaker is sending ALL of its sound forward, you're actually getting a relatively equal mix of lows, mids, and highs, as opposed to wide dispersion dome-tweeter type speakers that send about equal balance forward, but also significant midrange to the sides.Ī general rule that you could follow is that for a similiar overall performance class of speaker, the horn loaded one will probably sound better in a poorly treated enviroment but a wide dispersion speaker will probably sound better in a well-treated room. In traditional dome tweeters, you are radiating some extra sound to the sides such that in a reflective room, you might hear more overall sound in the midrange and the low range because what you hear for highs isn't projected so widely and thus its less efficient, especially at the high range, overall.Ī horn loader speaker will sound similiarly between different rooms because its allowing less of its sound to radiate in an extremely wide pattern in the first place. S i n α = λ D sin \alpha= \dfrac į 2 = s in 22.21 ° ⋅ 0.Any truth to these statements ? They're part of a post on another forum (but from '05) :įor an actual technical reason, consider that a horn loaded speaker achieves its high sensitivity by directing more sound forward and less to the side. We can calculate the diffraction angle using formula for the rectangular openings: When the person is sitting at an angle α \alpha α off to the side of the opening, they do not hear the particular frequency, so it is the diffraction minimum for the given frequency.
