More power?

Thanks for the response. I live in a loft, very open space, fairly assymetrical with high ceilings. When I listen I have to pull the speakers out to the middle of the room (and rearrange all of the furniture that's in the way...), and yes, they are toed in. I listen fairly near field (I've tried to follow the Audio Physic speaker placement guidelines as best I can). I get all the promised imaging and soundstage results, but just not much bass slam. Modifying the room (i.e. with tube traps, etc.) is not an option. I was thinking that because of the room size I might simply need more power to get the low end, but I would hate to spend the money and then realize that I had already gotten all the low end I can get out of the speakers with the CJ 11. Someone had suggested the Rogue M120 Monos as a possible option... In all other respects, I completely agree with your statement about the Virgos re: value and performance. After many hours of auditioning, I've concluded that I can't really find a better speaker unless I spend at least double the price, and so I'm just trying to get as much out of them as I can.

Based on your statement that your room is a very open loft, what you require is a subwoofer. While they don't go down into the 20Hz range, the Virgo is not lacking in bass when used in a reasonable sized room. In larger spaces they simply cannot pump out the volume with their somewhat smallish woofers. Would recommend either the Audio Physics models (Luna or Rhea) or the better REL units (Stadium, Stentor or Studio). If you can place the subwoofer in a corner, you will have all the bass you've ever dreamed about. BTW, two subs are better than 1.

And if I can't use two subwoofers, will using just one (off to one side) have an effect on the stereo imaging?

The recommendation for 2 subs is not related to stereo performance. 2 subs, if properly set up, will provide smoother bass with greater dynamic headroom. A single sub, again assuming exacting setup, will enhance, not impair the soundstage performance. Much of the soundstage information is derived from low frequency hall sound which only a full range speaker or a subwoofer can provide. Regarding using a single sub and imaging, if you set the crossover correctly, stereo imaging will not be impaired. This assumes that the sub is not too far to one side. Either the Audio Physic or the REL models will be easy to integrate into your system. Good luck!

I recently went from a CJ 11 to 8a's to drive my Martin Logan ReQuests. The difference was huge. Most noticeable was a big improvement in the bottom end. Try to find some 12's that you can try at home. I think you're efforts will be rewarded. Gook luck.
