Subs that keep pace w/ribbons & electrostatics?


Are there any subs out there that integrate well with full ribbon or electrostatic loudpeakers?

Gradient makes subs that are supposed to work well with Quads.
One very well known & respected Vandersteen dealer told me that he thinks the Vandersteen sub is an even better match. Haven't heard it, though.
I'm very happy with 'The Force' by ACI (audioc.com). It's
currently teamed up with my e-stats - before that with my
ribbon speakers. It's very fast and very musical.
