Can anyone please help me. I have a pair of B & W bookshelf speakers, 602s, that is connected to a Sony receiver (STR-DH100). I would like to complete the set-up with a budget sub. My limit is $250. I came down to two subs that have great reviews on CNET but I have never heard or listened to them before: 1. Mordaunt-Short Carnival 9 a. Frequency response is 25hz to 150hz b. Output is 100 watts 2. Outlaw M8 a. Frequency response is 29hz to 250hz b. Output is 125 watts I will mostly use the system to play games on my Sony Playstation and watch movies. I am looking for a sub that has a mixture of boom and musical fill-in. Thanks for your advice.
