I'm using these little gems ( Sony Core Series Tower speakers ) to replace my old Canadian made towers in my home theater surround set up. One of my old speakers died. They are being used as the left and front right speakers in my 5.1 system.

Honestly I was jumping around between a bunch of different brand floor speakers...got these for $98 each $100 off. Paired these with a Yamaha Aventage RX-A860. They are absolutely amazing with the sound they produce for music or movies. These speakers are really clear and actually get fairly loud!

I use it in my small office, it is the great speaker for the price.
