I like the rail gun idea! I have to admit, I wake up a lot of my flatties at night watching films with the subwoofer on. It's not a case of the volume, it's the vibrations going through all the walls. Not good, especially when I watch Blackhawk Down at 3am!
look up your local sound ordinances then call the police alternatively, do something loud and obnoxious at times inconvenient to him... vacuuming works well... as does running a table saw/power tool
I would actually advise against fighting back in bass wars. Used to do it in residence, until i got a call from the front desk (which is on the other side of the building) telling me to sod off.
Get the "chemical brothers - bass test" and turn it right up. But tbh I think it'll start some kind of bass war lol. Go talk to them, if you dont get any results inform the council. Edit - oops didn't read the above post.
Build a gauss gun (or a coil gun). Both inexpensive, amazingly cool and pretty dangerous. Err, destory the evidence afterwards though.
I do fecking love the Digitalism at the mo! If Digitalism were a drug, I would of OD'd by now! But I say Tearglass and Plateglass - Plague Burial for the Ultimate Bass Song!
I agree. Rail gun + breaking things = no more annoying loud neighbour. Also, your coolness level would go through the roof. However, the fuzz would NOT be on your side for that one.
Bass war is definitely the answer. My neighbors enjoy cranking lame, old cartoons all though the night, while letting their flock of young children (I'm not kidding, there are usualy like 4-10 kids over at any one time). So I brought a sub home 350watts of 10" sealed box bass pleasure. About a week after getting in all installed, most of the noise stopped.
I made a railgun once back in high school for our physics class' final project. My mate and I didn't bother following anything outlined in the project guidelines/curriculum whatsoever. The end result was a thin aluminum pipe that was about 40cm long with almost 4 inches of wire coiling around it. The demonstration involved firing shaved nails (the flat head was shaved off) into an ash wood block. Quite lethal at 100V. We had quite a talk with the administration shortly afterward, but we scored an A+... Back to the topic: most mid-range comsumer speaker sets are magnetically-shielded with some type of metal body (or at least the front center and front stereo are). I'd guess, because of its purpose, the subwoofer would be shielded as well since it's usually in proximity of something electronic like your receiver and television set.
If the sub is against your wall, you could drill trough the wall into the sub very carefully without pushing it away. That should give plenty of options - filling it with expando foam, water, sand, shoving it really hard with a stick, quitely poke holes inthe cone, etc
