I've got an old Pioneer SA-5800 amp and Advent Loud speakers. Not a great system, but can't afford a better one right now. Can I add an active subwoofer to this system to increase the bass ? Would a sub under $200 be worth adding ? For this old system, would I need a passive or active filter...I'm lost.
I need for my son's graduation party (outdoors)...would really appreciate any advice...thanks.
