I am looking for opinions for which sub to go with. It will be used with Paradigm Studio 100's, CC590 center and 590 di-pole surrounds. I like solid, tight bass, and a good amount of it. A lot of use will be for music of all types, jazz to metal. It seems some like a smaller diameter as they respond quicker but do not have as deep and volume of output compared to a similar larger driver. I listened to the 12 and it sounded very good. Have not been able to demo a 15. Any thoughts on my decision? I would like to stay with Paradigm for aesthetics in matching the front and center but not absolutely necessary. I like the sound of a sealed enclosure, many ported sound very boomy for my taste.
