i plan to build a sub for my saloon set up. Already have a pair of three way towers with 10" woofers that goes around 40Hz deep, . I have a mint condition KENWOOD KFC-W2510 laying around, crossover and more than enough amp. I've been countless hours playing with WINISD, and researching, but i cannot decide the basics of the build. My goal is to get some extra low end from 40 Hz down. HOW LOW DO YOU THINK I CAN GO WITH THIS DRIVER? any suggestion for the tunning frequency? by the way... the kenwood in WINISD database is the W2509, but all parameters are the same... im thinking a 50l box tuned at 24Hz? after build i will apply a likwitz LPF AT 50... but all this can change, please tell me if all this sounds good or i have any big mistake . Something like this:
