If you want louder to the ear just do what phoenix said. I had a 15 tuned to 33 and it would play nasty down to about 25 (mind you i had some extra spiders but wutever) and it still played up high pretty flat. I have my Z 12 in 32 hz right now and she plays low and high. Its retarded on the low notes actually.
