The only time i've ever heard the eclipse with a subwoofer was the 96 stereophile show in los angeles. they were mated with a set of genesis subwoofers. there were 4 in a column facing the crowd. very deep and articulate bass unlike anything i've ever heard of a loadspeaker at that time before. very integrated and musical. i don't remember the amplification or cross-over used in the demonstation.
