Seems a waste of timber and drivers by todays standards.

Have heard 4x 2x15 jbl full scoops in 400 person driven by crown, and was thoroughly dissappointed.

Have personally used either 4x mini/full 18" PD1850 scoops to coat 400 people with sub, and sub dynamics was much better.

yes it's in scale but I put different panel lenght from the sim model, so coul be a crap copy from that tiny pic ;P however could be a crap even with correct measure. The pic purpose is to show the layout. However months ago I already designed and published here a mini doglegged, so my eyes goes everywhere if I can learn something. smiley20

Yes, the 4520 is so great, that's why everyone still uses them, and not 1x18" full or mini scoops... :lol:

Could be folded as many times as Samurai steel..

Throw, sub depth, efficiency, ease of manufacture is the guy.

Have heard HOGs vs S118 3x times now, and even with extra fold and newer, advanced driver (1851), they still got murdered everytime by ye olde S118 & PD1850.

So sometimes simplicity is the hallmark of genius. smiley2
