Anyone know what speaker system those were used in?
Actually several, Santana and Madrid I know of.
+1 (Santana & Madrids) it was designed for a sealed cabinet..
Edit: Was looking for volume dims and saw your post sorry OG

I think GM has made some past posts, the 420 models well in a ported box, but bigger than the Santana/Madrid.
Speaking of Madrids my brother has a set cabs decent, dented aluminum dust caps, and a couple pinholes in tweets, which should be upgraded anyway. A hundred clams. Wouldn't take a lot to make them first class.
"B's" were late, 1974 and after, and are the premium 420 using a 16 inch frame and the cast motor of the 416-8B.
I'm pretty sure the Madrid was out of production by the time the 420-8B came along, but as soon as i say that an "odd duck" will surface.
So, a blown 420B could be reconed into a "real" 416-8B (same motor and 16" frame)?Quote:

My bad. I think you are right, but won't guarantee empty boxes weren't sitting around and stuffed later...have seen enough weirdness to be careful about absolutes. But have never seen a Madrid with 420B. only 420A. to be technical, 420-Z.Quote:

Ultimately, it's the 'woofer's' big VC that sets its rather 'lean' HF response and why it needs a super tweeter.Quote:
