Query: i use these for coasters

all my life i have loved audio. my dream was to buy a large scale system that sounded good. With a tight budget of only 5,000 dollars (US), i began to construct this thing. Epos LS12'swere my mains, and five granite audio monoblock amps. then it came to surrounds. these klh's came free. dont even hook these up kids. overall they must have a frequency responce of 900-901Hz. what i mean is, they have no bass, bairly midrange, no highs.
