I am a audiophile/home theater person that recently got my first audio system mainly for music and movies later on when I get a projector. My current system is a denon reciever avr-e200 with 2 JBL studio 130's. The music that I listen to sounds great and very pleased with the mids and highs. The bass is to my liking as I am not a bass fanatic, prefer the mids and highs, but I feel that a subwoofer is need for the home theater needs and simply it can add more of a punch to some music that might have more bass than others. Is a sub woofer worth the cost, and if so are there any good sub woofers that are less than 150 that will sound well enough to not sound like the weak link of my system.
