One of the reasons I mention stuff like this thread contains is, I remember debating the merits of SH's stereo subs in a thread (or 2, or 3), using logic and accumulated knowledge.

When I actually TRIED the setup, using the appropriate source material, per SH's suggestions, guess what...it worked, as advertised (and thanks to SH for his long-suffering at my expense).

Some of what gets posted is mistaken thought, some is pure gold. Nothing ventured, nothing gained.
