ES-18BPH Performance

there was some time ago, a thread debating the various merits of the es-18bph versus the 184 sub. conclusions were that the 184 was a slightly wallowy but very musical compact subwoofer (well tuned bp6, sounds about right) and the bph was a very kicky alround bass cab, ideally suited to fast and lively music and apparently finding good application as a cab for live band work, but never reproducing the really low stuff.

the design for the usb is floating around the forum and is probably the closest relative, the original speakerplans design that it is closest too is i suppose the hd15, in that it is somoe kind of bp4/horn hybrid thingumy. es-18bph will play slightly lower and i suspect louder than an hd15, but it's comparably bigger, so it's just horses for courses.

1850/186 horn are pure horn bass bins, they will play lower (especially in big stacks) than comparable numbers of usb/es-18bph style cabs but be much larger and heavier. the long folded horns don't like crossing too high either, some of the bp4/horn hybrids are suprisingly successful higher up the frequency range, for extreme examples check out the crossover points in funktion one's resolution boxes...

Do the funktion one boxes use phase plugs on the bass bins to increase the range covered?? (get higher).

oh.. learned.
