This sub has an xmax of 88mm. Would this be a good sub to run in a home theater? Also, what is the main difference between subs for cars and ones for the home? Also, why do so many people want to tune to a frequency lower than what is audible to the human ear? Sorry for all the questions as I am new to the HT thing, but an old pro at car audio since high school. Used to run Orion HCCA amps with multiple batteries and then switched to Lanzar stuff. Can't get enough BASS!!!
