More does not have to = Louder in terms of bass output,
The ultimate goal of a true bass head is to achieve full range frequency extension to sub hearing levels
Normal Human hearing range is 20 Hz to 20kHz
Most action Bluray movies have significant LFE (Low Frequency Effects) around the 30Hz range.
If your sub has a frequency cut-off above 40 hz , like most budget subs with smaller drivers and under powered amplifiers,
you are missing elements that you simply are not aware of unless you experience the same movie in a full range calibrated cinema.
The higher end subs will dip well below 20Hz , some DIY units are running single digit ULF (Ultra Low Frequencies)
At this level the bass is no longer audible to the human ear and the experience is more Tactile in nature...in other words you feel it instead of just hearing it.
If you don't have a sub that has a frequency range that reaches deep enough, you wont hear its full impact, but you can still see the effects...in this video and hear how they effect objects in the room.
The sound of higher frequencies are still present, but the sound waves of the ULF are the ones that have the have the power to move things physically
...the holy grail of full range audio is just that , full range, no limitations, and it doesn't Have to be loud to be thoroughly enjoyed/experienced.
For those who can't afford to buy, or don't have the space or means to build a DIY sub,
There are transducers (AKA ButtKickers ) that are designed to shake your chair giving a similar effect on a smaller budget.
There is a Master List of movies that contain LFE and ULF for true bass heads in the Subwoofer section
