Thanks...
It is tuned to 31 hz. I have the promedia 2.1's and it absolutely
destroys the sub in that system, and based on what I have heard of the
5.1 sub (my friend owns that system) it does the same with that. One
however, must take into account that it cost about $200 for just the
parts, and you don't get any satilites, amps for those sats and
whatever else. Because I tuned it so low and in such a large enclosure,
it's not particularily loud, but it makes up for this in cleanliness,
as well as low end extension. The RSW-15 is definitely superior, but
this sub actually sounds much more neutral/flat, and is just as
enjoyable to listen to for music (which is where it is needed).
This computer setup is used for mixing/recording music.
