Subwoofers with Fritz Carbon 7's?


I'm contemplating going from full-range speakers (Polk LSI15's) to the stand mount Fritz Carbon 7's. However, I'm concerned that I might be given up some of the bass I'm use to having. Is anyone using the Fritz Carbon 7's with a subwoofer. If so, which subwoofers, and how's the combination. I'm using Van alstine and Odyssey electronics.

Thanks,

I own a pair of carbon 7's. I would suggest trying without a sub first. It will surprise you how much bass they are capable of. You could then add a sub if needed.
Wouldn't depend on the room? A Passion, how big is your room? Like Bjl said one of the strengths of the Carbon 7s is their bass for their size.
Good point. My room is 14 x 16. At one point I had the Polk LSI 9 monitors which had a nice full side, but decided I wanted more bottom end and upgraded to the Polk LSI 15's. At the present moment, I'm thinking about going back to monitors.

A REL probably would be a safe choice. A set of stratas would sound amazing :P
How about a Rythmik F-12? I love mine and it is quite affordable, great resale value, and of course great sounding.
