ok.. so there was a dispute about what subs are louder.. i went to the shop (sound waves car audio in houghton lake, mi) and grabbed a few friends and we were going to have a meter night.. we got more than we barganed for.
about 10 of us there metered these subs:
re xxx 15 and 12
re hc 15
kicker L7 12
memphis LVS 15
and they were put in these enclosures:
3.5 cubes tuned to 35 htz
5 cubes tuned to 40 htz
2.5 cubes tuned to 33 htz
and another 3.5 tuned to 28 htz
the kicker only did 2 of these enclosures.. the 3.5 and the 2.5 cuz we didnt want to have to make special enclosures just for this test..
this all was done on an audiocontroll mic.
we used 3 cars...
a 1999 gmc sonoma with a eclipse head, to a memphis e.q. to a crossfire bmf 1000d
a 1996 ford explorer with a eclipse head to a us amps 3800x *(not sure the model number.. mono good for about 4k watts at 1 ohm
a 2002 gmc envoy with a alpine head to a kicker 1200.1
