I've long had a "sonic crush" on the sound coming from several cinema auditoriums and their associated speaker systems. This hasn't got anything to do with "hifi" per se (though strictly speaking, it should), but simply that the oftentimes effortless, full-bodied, dynamic, and indeed rather coherent presentation appeals to me immensely. That it doesn't relate to "hifi" (in the more or less traditional sense) as such is by no means to be understood negatively, but rather that it imprints itself intuitively as something "right." I find it the more interesting, even truer, that my impressions herein have been formed under conditions that "breaks" contrary to the typical environment under which we relate to hifi, that is in a darkened auditorium (usually) filled with people, no visible equipment, and a focus towards seeing a film.
This brings me to a shift or transition that is still underway towards... a settlement? Some 10 years ago a visit to a hifi-exhibition lead me to rooms with a range of horn-driven JBL speakers - the S4800's, Array 1400, and not least the overlooked S9800SE's. Here the sound, especially from the latter, in many ways gave me the sensation of "finally, at last" (closely related in some ways with the cinema sound experience mentioned above) and I simply kept hanging around and "inhaled" the music here for hours. I've not since become a JBL-fan, but it informed me about a preference that has since been sought after, albeit not initially with horns and compression drivers as the common denominator. Instead, my "deviation," so to speak, went from direct radiating tweeters to ribbon-based speakers (Raidho) and then to waveguide speakers going from the Finish Amphion speakers to US-based S.P. Technology/Aether Audio, and finally the Polish originated hORNS speakers where a variety of horns and waveguides are used in conjunction with compression drivers and pro-style mid/bass drivers, in what are usually 2-way systems.
What is to be brought from this is the addictive nature of the effortless, full-bodied and dynamic presentation from compression drivers paired with larger and efficient mid/bass units crossed over no higher than 1.4-1.5kHz - depending on the size of these units and their implementation. Moreover the mid/bass units here used are not sub-bass units per se, but have to be capable playing midrange as well - and this is very important; instead of trying to squeeze out sub-bass from one package a much more important emphasis is placed on the mid-bass and integration with the horn/waveguide and its compression driver, and so maintain only one cross-over frequency in a not too audibly critical spectrum. Whatever one seeks in the sub frequencies must be attained with the use of (preferably) two, or even more subwoofers.
So, this is not about a particular speaker or even brand to hang on to for life, but a speaker principle that has gone on to establish itself as indispensable compared to the more typical regime of hifi-speakers: direct radiating dome tweeters now sound thin, malnourished and strained; typical hifi mids sound compressed and lacking dynamic impact; and not least the upper bass/lower mids of typically larger multi-way hifi-speakers simply lack the cohesion to bind together this very important area with the rest of the frequency spectrum into a homogenous musical whole.
The typical application that is associated with this speaker principle I've now come to cherish for the last many years may not lead one to think of "hifi," but it doesn't matter - except for the ones who are lead to dismiss it out of a prejudiced stance; what matters is that it sounds like real, live acoustical music, something that would (or should) lead one to reevaluate the now established term "hifi" and question its merits as the true holder of the meaning 'high fidelity.' I don't disregard other opinions on what hifi is, but if the goal is seeking a live presentation of acoustical music in a real space environment then the matter presents itself less subjectively and into a different direction than where the established hifi-milieu has come to "coagulate" - if you ask me. Sorry for the detour...
