Hello all, I'm planning a new build and was going to use 4 DAD BD woofers but have been also looking around at different companies and wondered if anyone could compare the DAD BD's to the Fi SSD. I already own a BD-15 and love it, but have no experience with Fi audio what so ever. I'm going to run either 4 15's or 4 12's (most likely 12's) in my 1999 Subaru Impreza on a Cactus 5K. I need to get loud at fill tilt but sound good a lower volumes, my DAD woofers do this VERY well. If anyone has experience with these two woofers any info is appreciated.
