System advantages/disadvantages
Jonathan,
"High SPL" is relative, so quite understandable to not have noticed any lack of <200 Hz in a hotel ballroom, especially if the (more than adequate) subs are covering most of the acoustical response in that region, and the stage volume does not require the system "keeping up".
The increased off axis coherency of the co-ax horn loaded midrange response from the SH-80 certainly could be a sonic advantage over the front loaded JBL SRX 715 or 722, even though it has around 7 dB less output potential at 100 Hz than the JBLs (which require more power to achieve the level) or around 14 dB less than a pair of CLS960s, or my Paraline vertical array with fourteen horn loaded 8".
Different venues, acts and environmental conditions all place different demands on systems, it is interesting to compare the advantages/disadvantages of each.
Depending on the requirements, each of the three pictured below are clear "winners"- or not.
