- True. And also keep in mind that the subwoofer output gets a
- signifigant portion of the surround bass, as well. (For those people
- lucky enough to enjoy a subwoofer in their setup.)

-
- Dispersion is precisely the reason that manufacturers such as
- Cambridge Soundworks make speakers with divers that fire parallel to the
- intended audience location instead of directly at them. In fact, this may
- be a requirement for a THX-certified surround speaker, but I'm not sure.

- Well, you don't have to be an "audiophile" to want better
- speakers than the ones that Radio Shack makes. 8-O
-
- 8-) Seriously, though, I haven't heard them, so I probably
- shouldn't judge a book by its cover or a speaker by its manufacturer.
-
- I have also heard that one would want speakers that are all
- constructed by the same manufacturer, as such models would share
- similar characteristics sonically. This idea is probably just
- manufacturer propaganda, but I submit it for your consideration.
