It is still install dependent...both in ported box tuned to 30-40 hz. i want to sound good yet be loud
Others have had good results with tuning them to 30hz.go for the rl-p's. trust me they get loud. i had mine tuned to 39 hz. daily and they still had decent sq, although i recommend lower tuning for daily.
