Hi again,
I misunderstood you. To further clarify, yes, the old QS4s used a titanium tweeter, but only 3/4-inch diameter. We upgraded the tweeter on the V2 version to a 1-inch diameter titanium unit with better high-power handling. The tweeters now used on the QS4s are identical to the tweeters used throughout the Axiom speaker line--the same as the M80, M60, M22, QS8s, etc.
The QS4's woofers are slightly smaller than the QS8's, so they don't have quite as high power handling as the QS8s.
Regards,
Alan
