Has anyone used this driver for a paasive sub ?
I am currently working on a pair of open baffle and in need of some low end.
The driver i am using is consist of 8" coax fullrange and a peerless 830685 (6.5 midbass) and dayton ND20FB-4. All wrap up in 1st order 6 db at 220-1325 hz and 1325-9000. So far it sounded alright, very open sound. I am thinking doing something with the Peerless 850137 for the low end but could find very much info on the web. What would be an ideal box size for about 20 hz tunning?
