setting-up rel strater-3

REL subwoofers have to be the easiest subwoofers to set up. Just follow the manual and you can't go wrong. No one here can give you advice because your room has a great deal of influence on bass.

Look at the Sumico web site for detailed instructions. They recommend the soundtrack from "Sneakers"; I got a copy used on Amazon.

The Sumiko website just shows the owner's manuals. The problem with using one recording, like Sneakers, is you optimize your system for that one recording. I recommend always using a variety of recordings and find the setting that works well with a variety of music. Otherwise you will shrink your music collection to a handful of recordings.

No, if you get the best location for bass it will be the best for all records. What "Sneakers" does is offer a repeated bass note so you can move the sub till it is in the best location, this takes at least 2 people. One or more to move the sub and at least one to listen to the change. You are not evaluating the music, just the bass performance. The Sumiko site use to offer longer and shorter set up guides that are very helpful in setting up all subs. Any recording with a repeated low frequency note can be used but "Sneakers" was the one they recommended.
