[QUOTE="THATpurpleKUSH, post: 8635769, member: 615398"] I played around with them in BBP6 and they reach xmax on 1200rms in .8cf and up larger. They also didn't like a low ratio like 2:1, so go with 3:1 at the minimum but beware it gets a little peaky the higher the ratio is. Do .6-.75cf for the sealed side and 2.4-3cf for the ported side with plenty of port area (minimum 16sq inches per cf). Also beware there is a sharp spike in group delay between 30-40hz regardless of what design you go with. [/QUOTE]
