I was at CES and spoke with Richard. I came away with the understanding that the quatro is an attempt to reach a broader faction of audiophiles due to an increased WAF. It will not outperform 3A Sigs and 2WQ's, but has a purpose for the Vandersteen supporter who does not have an understanding wife :-) It looks real nice and can be used in smaller rooms due to its scaled down size. As for the sound, it has the 3A sig stamp!
Vandersteen Quatro speaker - link to info
Shortly after the CES, there were several posts here about Vandersteen's new speaker, the Quatro, which is positioned in the model lineup between the Model 5 and the 3A Signature. I don't know if anyone has posted a link to information about this speaker, but I noticed this evening that the Vandersteen web site now has a description of the new model. For those who are interested, here's the link to the Quatro page:
