A Subwoofer is a type of speaker that produces low frequencies at high volumes. People mostly use subwoofers in houses for home theater systems like in 5.1 surround sound systems and the it would also be used in cars, those are the most popular ways of where subs are used .
A subwoofer can be made of plastic and sometimes a sort of hardened paper .The skeleton of the sub would be made of metal and then there is the magnet and the coils what produces the power of the speaker.
The coils are like a electric magnet that when power is transmitted on the coils the coils act like a opposite magnetic pole of the magnet and that is how the coil then pushes away from the magnet .You also get dual coil subs and are also bit more expensive.Stick around and i will explain how that works.
Single coils tend to blow more easily ,dual coil usually have more power due to the fact that it has double coil and therefor have more wattage to work with.A subwoofer is more for people who love bass.I bought a 7000w sub the other day and just loving the sound so far.

rel subwoofer is like any other subwoofer but is of quite good quality and the rel subwoofer is not for cars if you guys thought of that it is more for you home audio like for a home theater surround sound systems the rel subwoofers have their own built in amplifier like any other home theater subwoofer
You can use the sub in the car but for that you would need a inverter for the power source (lol) who would actually put a house rel subwoofer in a car i would just because if you have the extra stuff laying around that is never used so it would save you some money ,instead of also buying an amplifier and a subwoofer for the car but any way thats what i would do if i had the money for a rel subwoofer
The sub is obviously constructed of wood and the box fine tuned for a specific frequency so that you could really feel that bass instead of hearing you have to agree feeling the bass is much more enjoyable than hearing it i mean you can go to a certain level of hearing but if you feel the bass it so more realistic.
The rel subwoofer is also for very heavy duty so that means that it can take quite a punch and the duration of playing at loud levels for long period of times can almost be endless.
