Cost to upgrade Vandersteen 3A's to 3A sigs.?? ?

The cost of upgrading your 3A's to 3A Signature status is listed on the Vandersteen web site. And yes, the cost to upgrade is a good investment if you already like the sound of your 3A's. My 3A's were upgraded to the Signatures, and I was very pleased with the improvement of the sound.

The main difference in the upgrade is inclusion of the same tweeter used in the Vandy Model 5 (but not the same one used in the Model 5A), as well as some changes to the crossover. Also, the drivers in the 3A Sig's are all very closely matched -- to within 0.1 db, as I recall.

Hi, 4yanx:

I haven't looked at the Vandy site to verify my comment, but as I recall, the upgrade from 3A to 3A Sig involves replacing the tweeter with the same one used in the Model 5, plus an upgrade to some of the components in the crossover. The mid-range driver in the 3A is the same one used in the Model 5, and this is also used in the 3A Sig.
