i just picked up the new loudspeaker handbook from eminence. it is much more thorough than last year's. complete descriptions of every thiele-small parameter that even myself & bill epstein can understand. also includes recommended box volumes for each driver. no wonder my theater 4 pi's have no bass, the delta pro is meant for a much smaller box!
they now provide the sensitivity of each driver at various frequencies. something i found really cool was how 15" drivers start to beam frequencies at 1052hz, 18 inch woofers start beaming at 903hz. i wonder if horn loading these large woofers would alleviate this problem? they also chart each driver by frequency performance and give it a 3 to 5 star rating for performance. real cool! the new line of deltalite drivers looks interesting as well.cheers, george
