1. Whether you set your speakers to small, or leave them as large, depends on the bass performance in your listening room. The main speakers are placed in the room for best stereo imaging. Subwoofers are placed in the room to provide smoothest response. In most rooms, it is unusual that the same placement would produce both the best imaging, and the smoothest bass. Being able to separate these two objectives by having one or more capable subwoofers, and letting them handle the bass by setting the mains to small, is an approach that is highly recommended.
Having said that, in your particular case, you should measure bass performance with the mains set to large. If it is acceptable to you, there is nothing wrong with leaving things as they are.
2. Depends. Again, everything hinges on your ability to measure bass response with, and without, the sub.
3. I doubt that headroom plays a significant factor in your decision.
4. Not that I am aware of.
Very nice speakers, by the way!
Thanks for the response and kind words Jerry.
Do you have any recommendations on how to measure the bass response? Does this mean just listening to the setup with and without the Velodyne sub in the mix and see which sounds better or is there a more analytic approach?
Would this be the proper checklist to go down?
- Fronts set to small + dedicated velodyne sub
- Fronts set to large + dedicated velodyne sub
- Fronts set to large + no dedicated velodyne sub (4.0 setup)
And one more question -- when I set my fronts to small, does that mean the subs on those speakers are not being used at all? Is it just the 4' line source that is being used then?
Its unfortunate that I can't benefit from the Audyssey high filter resolution on the sub channel using my Wisdom subs.
Thank you for the help!
