Hi, my grandmother wants me to install 1 or 2 speakers in her hallway so that she can listen to music while she is cleaning the house. I'm not positive but I believe her receiver is pushing 100W per channel. Anyone have any suggestions on either 1 or 2 speakers that would fit the bill? the hallway is roughly 20' long and about 3' wide. She wants me to spend around $25 each. She is no audiophile and just wants something to be able to hear the music. I would prefer to be able to just run into Circuit City and grab something there if I can. I see a pair of Sony's for $50 for the pair, would this be ok? Thanks.
