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?

Interesting thread, I stumbled across while looking for information and thoughts on LaSacala II's as I am thinking about buying a pair. Previously I owned a pair of Heresy II's, one of the few I bought new. At the time I was running all ss gear, Classe’ DR5 & Perreaux 3150. They suffered from the fatal 'fatigue factor'. I suffered for some time with them and thinking it was the speakers fault I eventually sold them off and replaced them with QC-10's which remained my main speakers for years.

Since that time and many upgrades later I ended up with tube/ss set up (ARC LS27 & ML333). Gone were the DQ-10's replaced by Shahinian Hawks on the main system and Obelisk on second system tube/ss ARCLS17se & ML 23.5). I recently dug out of storage a pair of KG4's and as I was contemplating new speakers. I thought I would plug them into the main system to see if they were still as fatiguing as I recalled. As I listen to multiple genres depending on a given mood at the time I was quite surprised by the sound (as I was initially with the Hersey II). So, I thought I should run a few extended listening sessions, which I did.

 

Base was there, improved by keeping the subs from the Hawks with them, mid and highs were clear and spot on, a very nice surprise. Wondering if they can be improved I went with the Crites crossovers and new tweeter. Unfortunately, I upgraded both on the pair and I was somewhat disappointed with the result...something was missing that was previously there. In retrospect I wish I had done either the crossover or tweeter and then listened before completing it.

However, after another several listening sessions, either I forgot what I had initially thought was missing, or perhaps I was just wrong. I am still not sure why I had such an initial bad impression of the upgrades.

This reintroduction to horn speakers has taught me that you need to be careful with all the associated gear and that perhaps I should take another listen to their current line. I have zeroed in on either the LaSacala II or perhaps the Khorns if I think the room can support them (12x21).

So, the only thing I can say in favor of horns is yes, they are not for everyone and depending on source material may not play well with all types of music. However, I have liked from the first time I had heard them and with the proper matching of supporting components they tend to be very musical. Much like the Obelisk's in my experience is that having tubes/ss in the loop seems to tame them and makes them much more listenable. Might I get tired of them again, perhaps but that is why I want to live with the KG4’s for awhile and fire up the Hawks when I am in the mood for some classical music. But for now…. I am loving the KG’s.

The Heresy IIIs do need, for my tastes anyway, a good sub to make a full range system. I use 2 RELs I already owned when I bought the Heresy IIIs, and they took some time to adjust as they were getting significantly less signal from the amp as the Heresy doesn't need more than a watt or 2 to get going. I'm in the "all speakers should work with all music camp" as music specific speaker design would be ridiculous (except for ultimate level limits) because classical, heavy metal, and those middle eastern monk yawning albums all need the same mojo coming to your earballs. I mix live shows and use the same speakers for the Baltimore Consort or Julian Lage. Heresy IIIs are coherant, exacting music reproducers, I'm never thinking while listening to them that they're horns, they can expose flaws in your rig or a recording if there are any, and they have surprised me with their tonal accuracy. I think everybody should drop what they're doing a buy a pair immediately. Get a pair, as they say.
Science and the science of how we hear are as yet imperfect...... 

like Baskin Robbins, a wide sample is best before deciding on that single cone....

better to get three....to paraphrase some desert wisdom:

Life is uncertain buy many speakers first

wolf - where are you mixing sound next ?????
