You need more efficient speakers or a 1000 watt stove.
With the 86db Vandersteens and 40 watts of continuous power you should be hearing around 101db of continuous SPL at listening position.
It is to my understanding that the Vandersteens are not "high volume" speakers.
If you want some serious "rock out" speakers you may want to try something on the order of 92db+.
THe VSA VR4SR is a very good speaker.
Possibly the high efficency Vandersteen?
Good luck!
