As a self confessed "BassHead" I actually fitted a dBX sub harmonic synthesizer to my surround system that generates the bass information an octave lower to feed a pair of ridiculous sub bass cabs, so you REALLY feel those explosions
It actually blows stuff off the coffee table when it's in full flight.
But if you are having trouble with the neighbours (I have a well detached house!) then there is a solution to your bass woes, but it's not a very "hifi" one.
You can fit small bass effect units onto the bottom of your chair/sofa/etc that you connect to your amp the same way as you would an ordinary loudspeaker.
These will vibrate with low bass signals, thus giving the listener the
impression of wall shaking bass without the hassle of
NDN (next door nagging).
You can also get some pretty good transducers these days that affix to any flat surface such as a window, coffee table, etc, that will turn it into a loudspeaker.
Again, not the pinnacle of hifi reproduction but it can produce a startling effect!
I'm not sure if I'm allowed to post the website link of the supplier of such delights within these sacred walls, which is in Germany but in the English language, so if the inimitable Mr.Everard approves, I will re-edit this post with the details of said emporium.
EDIT :
Thanks Andrew.
Have a snoop around at
www.thomann.de for the bass shakers and transponders.
P.S. I am not affiliated to this company in any way, I just find there range and prices to be pretty good.
