Best used speaker for $2,000 for rock music

Source Technology has a new speaker - 8.3DX - that should fit your needs --- if there is no dealer in your area, you can purchase a new pair direct in your used price range.
I own the 8.2DX and 90% of the music I listen to is Classic Rock and these do the job quite nicely -- the new 8.3's go lower in the bass.
800 - 599 - 7558
I don't have a finacial interest but I recently received the info on both speaker models if you want me to email them to you.
Best of Luck

You need to add Von Schweikert VR2s to your short list. In the right room, these speakers do it all and do it extremely well. This includes dynamic rock or metal. And best of all, they can be found on the used market for well under what you are willing to spend.

The Aerial 10T is a Monster at $2200-2700 used. It will eat some of the above speakers for breakfast. They love to play loud! I am serious some speakers sound great at lower levels. The Aerials come to life under Rock and Roll concerts. They are great top to bottom and feature the new england style sound which is a slightly softer top end which is perfect for Rock as many recordings are less than steller.
