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,

How about a Rythmik F-12? I love mine and it is quite affordable, great resale value, and of course great sounding.
We used the Carbon 7's in our 14 x 19 room at THE SHOW with 40 watt push-pull tube amps. While we had a sub, the Carbon 7's did fine on their own so we ran them without the sub. I'd recommend trying it that way first.
You really don't need Subwoofer with Carbon 7. IMO, the best
monitors under $4000.00
