I likewise own the Dunlavy V(s) and have been very pleased. In 25 years of following this hobby I have not found there equal, and 'yes' they can play loud without any noticeable strain. I might also mention the benefit of listening to them at various points from the back and side walls, in that when at there optimum placement are capable of simulating a multi-channel environment with just two channels.
Loudspeakers played LOUD
I listen half the time to really loud music. I chose the Dunlavy V for this reason. They are very accurate and can handle high volume. Are there any better?
