Don't let anyone tell you that you need expensive in-ceiling speakers.
They are by their very nature not for critical listening, so there is
no need to get anything fancy. The speakers I mentioned above sound
great at either high or low volumes, and I have gotten numerous
compliments on them from guests in my home.

I'll agree. Just 'having' sound in an area is an improvement. That it's
not 'audiophile' quality is a lot less of an issue when we're talking about
hearing the morning news while in the shower. I'd want 'better' speakers in
places that might have most focused listening; the living room with a
fireplace might be a place you'd want to be able to hear really good quality
sound. But plenty of places don't 'need' it.

Likewise consider the wattage involved. Driving more than 25W into a
bathroom or other small area might be a complete waste. Or pushing only 35W
into a really big space might be woefully underpowered. It's good to make
sure you that if you need to mix-and-match things that you have the right
equipment AND the right wiring in place to accomodate it.

As in, when pulling wire don't overlook the possibility that installing
centralized speaker wire NOW (into larger spaces) might be alot cheaper than
trying to add it on later. Wire is usually a lot cheaper than the labor and
hassles of pulling it again later (and breaking the stuff pulled before...)
