Hi all. I'm thinking of adding a sub (probably Dynaudio) to my set up which consists or Chord CPM3300 amp, Totem Mani II sigs and sources. The listening room is 8 x 4 meters, irregular wall's (barn), 5 meter ceiling and stone floor. I have plenty of soft furnishings which obviously helps. Sofas, rugs etc. What i'm trying to gain is a better frequency range across the board. The Frequency Response of the Mani is 29 Hz - 20 kHz ± 3 dB but a lot of the low end frequencies get lost as the room is so big so would adding a sub help with this and reveal more of the higher frequencies or would it be a dead end? Financially the sub would be a cheaper option as a decent pair of speakers would cost considerably more. How about acoustic damping behind speaker? Any ideas? [Y]
