I have just noticed that my Marantz SR5023 (80 wpc) has a subwoofer out and was wondering whether it would be a good idea to add a subwoofer to my existing set up. I listen to a wide variety of music and movies. My other components are Monitor Audio Silver RX2 speakers and Marantz UD5005. Was looking at the Monitor Audio Silver RXW12 - would this just make the whole system overweight in bass? Dont have room for a full blown home cinema set up i`m afraid.
