Danley is an innovative company in respect to horns, for the last 20 years the rest of the companies were partly making the older designs better and these are generally pro-audio companies. The home audio or hi-fi companies were barely innovating at all.
Anyway, the horn coloration is not only related to the type of horn but to how it is used in the whole speaker system. Everything has an effect, from the chosen bandwidth to material the horn is built. There is also the classic problem of what is the coloration we are talking about and if what we are talking about is the same thing. These "words" get lost and also have different meanings in different peoples imagination.
I am lucky to have klipschorns (fully modded by Volti audio), a custom built 5 way horn system at home as well as lot of other horns in my shed or at my business (cd type, conical, tractrix, jmlc, pro audio horns in arrays etc) to listen and measure for their differences. To contrast these topologically, as a former studio owner, I have also kept a variety studio monitors which hopefully lets my ears not get caught up in one type of sound reproduction.
After all these, and a passion for horns, I set-up a company as of this year and will hopefully be bringing out an original horn speaker design next year. It is not a complete new way of thinking like Tom Danley's but still an original approach to horn speakers. I hope these are ok to write here if not please let me know and I wil take the rest of it out.
As far as I know there are no other commercial horn speaker design like the new speaker we will be bringing out. If people think it resembles my system, it is nothing like my 5 way horn system. I have been testing, measuring and listening to my finished prototype for the last few weeks and when the product is out, hopefully it will bridge the gap between the people who like planar/ribbon speakers and horn speakers and people who prefer less colorations. All my initial tests and measurements prove to be very good so I am quite hopeful on the outcome. As you may guess, nothing, no speaker is free of coloration, if one says so, they are meaning something else than what I am meaning.
I am taking my time for refinements, also waiting for the xo design that will replace the test crossovers from a very well known US amp and xo designer whom we are very lucky to be collaborating. We will share proper and varied measurements with the product roll-out. The measurements I have now are quasi-anechoic, in room response and electrical measurements. We will also be providing actual anechoic response measurements along in room responses from a variety of different rooms. I hope to bring a different and original choice for horn lovers and people who wants to get into horn speakers
