Here is a Khorn

TWEETER: K-77-D 1" (2.54cm) Phenolic diaphragm compression driver
MIDRANGE: K-55-X 2" (5.08cm) Phenolic diaphragm compression driver
MID FREQUENCY HORN: Exponential Horn
WOOFER: K-33-E 15" (38.1cm) Fiber-composite cone / horn-loaded with a trihedral exponential folded

Here is a Heresy III

TWEETER: K-107-TI 1" (2.54cm) Titanium diaphragm compression driver
HIGH FREQUENCY HORN: Tractrix Horn
MIDRANGE: K-53-TI 1.75" (4.45 cm) Titanium diaphragm compression driver
MID FREQUENCY HORN: Exponential Horn
WOOFER: K-28-E 12" (30.48cm) Fiber-composite cone

Here is CWIII

K-107-TI 1" (2.54cm) Titanium diaphragm compression driver
HIGH FREQUENCY HORN: K-79-T Tractrix
MIDRANGE: K-53-TI 1.75" (4.45 cm) Titanium diaphragm compression driver
MID FREQUENCY HORN: Exponential Horn
WOOFER: K-33-E 15" (38.1cm) Fiber composite cone (ported not horn loaded like LSII and Khorn)

I looked this up as I forgot the details...but I knew things had changed.

Funny story.....the CW III and the Heresy I,II,III now have the exact same midhorn.... the K700 (crossed at 700Hz) Apparently, Klipsch lost the mold to the K600 found in the CW I and II.

The Heritage series keeps the midrange Exponential horn out of respect for PWK. To me, that is the biggest drawback of the most up to date Heritage version being at their pricepoint.

I have had a La Scala II and loved it mostly, but I would not pay that kinda money. My complaint is the midhorn. The exp mids sound too congested to me. Just My opinion. I sold them. I could of swapped out the midhorn but didn't want to crack open the back chamber and ruin its orginality (sp).

The modern day tractrix technology used in all their other stuff sounds much better. IMO.
