Horn based loudspeakers why the controversy?


As just another way to build a loudspeaker system why such disputes in forums when horns are mentioned?    They can solve many issues that plague standard designs but with all things have there own.  So why such hate?  As a loudspeaker designer I work with and can appreciate all transducer and loudspeaker types and I understand that we all have different needs budgets experiences tastes biases.  But if you dare suggest horns so many have a problem with that suggestion..why?

Does the hearing ability of the individual make any difference in the opinion of horns? It seems like they provide more directional energy thus providing a better experience for those who have lost a little top end or detail in their hearing. I have never owned horns, but the giant horns at audio shows always intrigue me and I would really like to hear them.

While I’m surprised this hasn’t been suggested (or even more overtly insinuated) more often by those in particular who couldn’t care less about the sound of horn speakers, be they hybrids or all-horns, I’d link the love of horn sound to sheer taste and perhaps not least a more conscious and seasoned approach into the reproduction of sound. Horn speakers, certainly all-horns, are in the clear minority compared to the vastness of the direct radiating alternatives, and generally take more effort to get to sound well - both in regards to the implementation with ones remaining setup, as well as the development and final execution of the horns themselves. Most so-called horn speakers though are really hybrids (and I can’t for the life of me fathom why this distinction isn’t carved out more clearly in the discussion of "horn" speakers), and so many may be predominantly referring to the challenging aspects of their reproduction here that commonly comes down to the lack of integration between the horn(s) and direct radiating units. Conversely all-horns can represent a different set of challenges compared to hybrids, that may likely require of the listener to make an even more radical decision based on several factors. The complexity of all this, and all-horns in particular being rather far between, requires a far more selective and, to my mind, seasoned approach in putting together such a system. When some people here refer to their less than favorable impressions of horn sound I’m often brought back to the realization of the above as a sad reminder that many mayn’t have heard a true, carefully developed, assembled and implemented all-horn system. When done right, and I admit this may be something of a rarity, such a system brings you close to a musical event just happening before you, uninhibited and naturally; no talk or thought of "hifi," but simply music in a very pure and emotional form. Lately I’ve been rather disheartened listening to some of the bigger brands horn hybrid solutions that seem to be neither here nor there in their sound. Certainly impressive in some regards, but I’m afraid all to easily (and quite understandably) fueling the thoughts in some as poor representatives of "horn" sound. It’s an industry, alright, and one where "going the distance" in such realms of speaker principle/design is the less sought way.

Having heard the newer Klipsch offerings, I’m going to go out on a limb and say horns need no longer be so controversial. Affordable good sounding ones are out there. Like anything else some will like them and some will not. Their clear advantage is the extra efficiency which may well matter quite a bit for many. No harder to drive than most others at a minimum as well it seems. Probably much easier to drive properly than most.

Regarding horn use and abuse, I use a pair of Mackie 10" 2 way P.A. passive (passive aggressive) speakers (with a beefy Mackie sub since they’re good to maybe 60hz) daily for my mindless but important electric guitar noodling in my mindless noodling studio setup. Note that the these little gems are the original version that cost around 300 bucks a pair new and seem to be made from some sort of plastic cement (heavier than the latest "neo" magnet woofer version which I imagine also sound real good). Interestingly, if you put recorded music through these (as opposed to my noodling tracks) it sounds sort of great. Heresy again. Plus, I’m not sure I spelled "noodling" correctly but it looks right.
