I currently have a Cerwin Vega LW-12 12" powered sub. I have the opportunity to get a Boston Acoustics 10" PV-600 or a Klipsch KSW-10 a really good price. All other speakers in my system are Bostons and frankly, I have been looking for a sub that takes up a little less room. Does anyone have any advice on this or experience with the Boston PV-600 or the KW-10 from Klipsch? Will a 10" vs. a 12" be noticeable on in my average sized living room?
