I have a Denon mini system in my kitchen/dining area. I replaced the stock speakers with a pair of Polk Audio RT25i I picked up from a big box store for <$100 a few years ago. The CD player on the unit is broken, but I don't care since I use it purely as an FM receiver and amplifier. I have an semi-legal FM transmitter attached to an audio output on the receiver in my living room that send out whatever material is playing. The transmitter is strong enough to interfere with neighbors (~150ft last time I measured), but I have it set to dead frequency.
