Hey all, I'm quite a novice to buy sub woofers. I want one cheap but of good quality. I am still in my teens so cannot afford much due to no jobs I want the best quality i can get for money really. £50 tops but i want a sub that will shake your body. Its quite demanding yes but that is my wish. I love a sub that you can feel pump through your body. Any help or suggestions is highly appreciated. NOTE: This sub woofer will be used on my PC.
