did I not say stoopid loud can be fun. I was just trying to get the point across that you dont need 1000w for a sub to sound good as at non deafining levels. you wont use anywhere near 1000w even if you have it at normal listening levels. accurate music reproduction is never boring unless music bores you

...I guess if you have already permantly damaged your hearing then stoopid loud is your only hope to hear anything, but for those of us who value our hearing and are trying to hold on to it because we love music, stoopid loud is only fun is V short bursts

Why does a sub need 30mm xmax and huge motor structurs/magnets/voicecoils if you're only feeding it 100wrms?

Just because I can..

If you are listening to 92 decibels at 1000 Hz then at 20 Hz you require 120 decibels to have the same loudness.

Therefore at 92 dB at 1 watt at 1 meter you would require 630 watts RMS.

If your listening to modern music (2000 plus) you only require 3 db of head room.

1990 6 dB
1980 12 dB
1970 18 dB.

Unfortunately if you listen to classical a full orchestra can EASILY require 70 dB of dynamic headroom.

1970 music you would require 39810 watts RMS without clipping.

for the record a CD CAN give you 90 dB of dynamic range.
