Got a question about live sound. I'm looking to get some bass subs for our PA. Leaning toward passive as opposed to powered. I'd like to hear your thoughts and recommendations. Using them for club gig's. Most of the clubs are 300 - 400 capacity, however I'd rather have more than I need than not enough. I'd also like to avoid super heavy gear ala dual 18 type stuff. Thanks for the input in advance.
