ive had this suggested because they are really loud. and it kind of interests me because i cant seem to figure them out. how does it work when it doesnt have a magnet or a voice coil? please explain it in a way that a non-technical savvy person such as myself can understand
 
It's a speaker without a magnet or voice coil. It use the air pressure of the active speaker to move. Sound like dookie :(

Get something in a band pass enclosure if you want some bump in your trunk.
 
AKA Passive Radiator.

They're good at increasing enclosure volume without making said enclosure much bigger. they're absolutely worthless on their own and need a decent driver (sub) to make them somewhat effective. That's about it.

It's more of a gimmick than anything. If they were worth their weight you'd see them much more often in commercial products.
 
an explanation that i read is that it adds onto your encloseure to complement the bump and sound of the subwoofer using the airpressure. its interesting. especially since it doesnt require an amp
 
If you're limited on space they might be worth it, but isobaric push-pull probably has the same output with less space. Of course the passive radiator is less expensive, but it's also less efficient (if space is a concern).
 
so would it be worth $30 to put one on your system? or will it make no significant difference
 
well. i mean do you think getting one would be worth the money?
