I have the DQ20 with new woofers and a reference rebuilr Ampzilla II. The bass is scary it goes so low. Primarily from 5.1 sound track. I owned the 10s and felt they were not as open as I like. I prefer electrostats or Maggies but do not want to dear with the placement or power requiremnts.Plus the DQ20 has more slam being a conventional speaker. I have been completely around the block wuth audio but ended up back with G.A.S. and Dahlquist.
