Ease, coherency, large staged sphere-like presentation, virtually unlimited full-range dynamics, high resolution and transparency, and natural tonality are the core traits pursued and achieved.
"Full-range" with a proviso; to some what is full-range covers down to or even below 10Hz at full click, but in my use of the term I "merely" refer to honest 20-25Hz, which my corner-loaded tapped horn subs will be able to achieve up to +125dB's - at the listening position. I never use their full SPL envelope even when being "liberal" with the volume control, but that's the whole point behind ample headroom: it translates into absolute effortlessness at any desired volume, while also making you more comfortable at higher SPL's (but be sure to project your hearing and avoid extended exposure to higher SPL's).
Some may ask: why actively driven and frequency extremes-augmented pro cinema main speakers in a home environment? To put it shortly, because well-implemented - which goes for all speaker categories - they can sound great in most any audible aspect, absolutely effortless at that, and at a price level that calls for one to self-scrutinize when comparing them to "high-end" speakers/subs costing a downright fortune.
So, what's the catch? Mainly it boils down to looks, size and conjecture. Aesthetics are very important to many audiophiles, more so than many will admit, and very large pro cinema speakers with their typically black Duratex surface and rugged industrial looks don't appeal to audiophiles with interior decoration demands, be they self-inflicted or by their spouse. Even if it doesn't concern interior design audiophiles often want or expect their speakers to have a particular "audiophile" look, which typically translates into a slender and deep enclosure with smaller, inefficient drive units. Finish-wise high gloss lacquer surfaces with (concealed) wood or other beneath it, are very popular. That's HiFi speaker looks in a nutshell.
Size and preconceptions: audiophiles at large would rather pay dearly for smaller high-end category speakers than have much larger, cheaper and less "fancy" looking alternatives with pro or DIY origins in their homes. It feeds the association that high-end speakers of limited size are refined, cultivated, voiced-by-ear and naturally adapted to home environments, whereas large pro cinema speakers and horn-based subs are coarse sounding brutes and only about playing hellishly loud. What's mostly incorrect are the assumptions aimed at the latter, while the former severely lacks dynamics, presence, scale, fullness and effortlessness of reproduction - something the latter has in spades in addition to (and this is fooling many an audiophile) resolution, coherency and refinement - not least actively driven. It's about letting physics have their say, prioritize proper implementation, and cutting loose conjecture and vanity.
The fact of the matter is that with care taken implementing a pro cinema speaker setup and not least driving them actively, they will serve up a sound that in previously named core aspects obliterates most any lower eff. high-end speakers. Add to that a great source/DAC, care taken with cables, wall power, coupling/decoupling and acoustics - something, I take it, most audiophiles wouldn't fully consider with this segment of speakers - and you'll end up having a speaker package with no severe limitations in most aspects of sound reproduction.
