I've just completed my first elusive 1099. Tried it with a Sony amp and feel it's low frequency response is pretty low. All the speakers work and I double checked connections. In contrast my Elac floorstanders sound much more punchier. Even the single woofer Sony speaker that came with my mini component seem to be better at low frequency response. I understand that these have to be coupled with a sub to be used in a theater but hoped they will still be good as standard speakers to be used for music without a sub. Is it not the case?
