I realize this is a loudspeaker thread, but a loudspeaker is all about the room. And a room is all about the time domain.
I could live with a hugely dynamically capable system, and the absence of the room "fighting back",...that's what I'd lust after.
First, whether I'm enjoying mixing an outdoor show, or merely attending live events outdoors, when you're outdoors, the LF has this fantastic characteristic that is so elusive otherwise. The total absence of destructive LF modal behavior, or SBIR, is a trait that I'd love to have with any system. As wonderfully tight the bottom end is outdoors, the sound-field, or lack thereof
, needs some measure of additional, diffuse, returns to the LP. So perhaps some type of anechoic below the transition, and ideally acoustically optimized above the transition.
So I'd pick something like Meyer's Acheron below;
And the accompanying mid-bass/LF counterpart;
I've always wanted the big Westlake SMS-1's, but never got to hear them,....they are still available today. tower style, or soffited style;
Ever since I heard a set of these JBL's, I wanted them. These classic JBL designs are superbly engineered, and highly sought after today;
Below, is relative new-comer to the big monitor scene is Adam. Contemporary drivers, and materials, in a M
approach. I'd like to hear them in a good room.
Either an implementation of an idealized Double Bass Array, or some type of outdoor system with a wonderfully diffuse, fully enveloping sound-field at the LP. All this without any reflected, destructive LF energy. So indoor, the space would be anechoic below a spec'd frequency. Outdoor, physical elements would be placed as to be only diffusely reflective above a specified frequency. This way, all diffuse spectral cues are maintained to the sides and rear of the LP, and yet there is no destructive modal behavior.
It's amazing how well our psychoacoustic process is forgiving wrt various aspects of acoustic compromise. But some type of active design that possesses a reasonably smooth frequency balance, both on and off axis would be really nice. But time coherency in speaker design, implemented in a space that's damped properly (doesn't fight back) below the transition, would elicit a sense of speed that's difficult to achieve otherwise.
btw; all the above loudspeakers implemented into a full, bass managed system, would be supplemented by ample displacement of whatever driver/amplifier du jour
necessary. Whether it Thigpen's Rotary, or conventional cones, there would be so much displacement that the coil rarely/never leaves the linear aspect of the gap, or encounter the non-linear elements of the soft parts. So whether it's Funk's LMS', Bosso's dual opposed, Seaton's dual opposed, Danley's dual 21" TH, whatever it is, there'd be ample displacement to overcome absolute lack of any PVG. Also, they'd be physically arrayed, and subsequently time delayed, as to acoustically sum at the LP.
