I have 8 Le15A's I would like to use in a 4 way system. 4 per cabinet,size not to important. Like 24 to 30 cu.ft per enclosure. Midbass will be 2202 or 2220. I dont know if JBL quad array would be good as the biamp frequency between 200-300 Hz. Probably more like 200hz with the 2220 dont think the 2202 will keep up with them. Was thinking a 2 by 3 pattern. Your thoughts will be helpful. Thanks
