Dayton does make a very good speaker, and I wouldn't hesitate to buy more of their stuff. I use the 6.5" "classic" woofers and their titanium dome speakers in a home system and they sound awesome! Especially for the money...
Its a good thing I don't live close to PE... I'd be broke...

If you have a harbor freight near you they usually have multimeters cheap (pretty decent for the money!) I've got a couple from them, when they're on sale they're around $4... Pretty handy to have around.
