I'm looking for a decent 10" at about 0-120$/each, that would be a good performer from a box no larger than 1.2 cu.ft. or so and filling up 30 to 35hz-55hz relatively accurately, of course going lower than "30 to 35" is ok too This sub will be going into a medium room sized about 1800 cu.ft. and for a purely music system. Already have an amp and it has about 170w [email protected] to play with. Also, I forgot what is that word for the ____ distortion... when for example one sub will not sound as good as two subs recreating same volume as one sub. Intermodulation?
