that sounds more like it :-)
I knew the 2000Hz figure was nonsense, and hoped someone would know the
The.1 in 5.1 to represent the fraction of the bandwidth sent to the sub.
For a 250Hz x-over, it should be called 5.0125 .
In any case, most so called sub-woofers have a lowest frequency of 50Hz or

I would have thought the center speaker helps a bit, as it allows a
angle between the front L&R speakers.
