Update on the 5000R.
I've just got done doing back to back comparisons with my Energy S10.3. For the S10.3, I raised the receiver's Sub levels 3dbls higher than the Velo to get maximum SPL without getting boomy.
Movies include:
War of the Worlds - Pod emergence scene
Star Wars Ep 2 - Ship Landing
Star Wars Ep 3 - Republican Star Destroyer overhead
All three of these scenes go into the 20hz or so and perhaps below in my room. I put the Energy on top of the Velo as well as in its position.
The most obvious observation: The bass on the 5000R is noticably cleaner and more defined than the 10.3. There's a clarity to the bass that's missing from the 10.3. However, my ears felt like they were going to POP from the low bass of War of the Worlds and the Star Wars scenes with the S10.3. I did not get that feeling AT ALL from the Velodyne. It was loud, and the floor shook like hell, but the feeling of being squeezed to death by the bass wasn't there.
So, it looks like the S10.3 goes lower than the Velo. I'm guessing in my room, somewhere in the 19hz-22hz for the Energy and 25-28hz at best in Jazz setting for the Velo.
So, what do I do? I want the pressure cooker sensation of the S10.3 and the clarity and authority of the Velodyne. Right now, it looks like the Velodyne is going back.
