I did not like the two slit configuration of the phase plug..but the five to one compression ratio produced low distortion,,,but i was not impressed with its bandwidth,,,JBL also used a eight inch speaker assembled to a special phase plug,, You will find it in there TECHNICLE PAPERS... I found it more musicle,,in theaters with out stress,,, the 2490 needs to be coupled to a 2393 type horn,,,another product long throw horn with its own polor problems,,Rerurn to Romy the Cat's Site
