We've actually had this part number for some time. It's about time that it was shared with you guys. Here's the deal- For $272 each speaker, you get a kit of parts that essentialy turns a H II (NOT H) into a H III. It appears to be everything but the new slant riser base.
Order part number 1006972 for parts to upgrade ONE cabinet:
K 107 TI titanium Tractrix tweeter
K 52 TI titanium mid driver
K 28 THUMPIN woofer
new crossover network with wire bundle
mounting screws and gaskets for horns and drivers.
Attached are the installation instructions and parts list.
Note that this is recommended for the EXPERIENCED INSTALLER only!
You will be asked to provide a valid H II serial number for each kit purchased. This is to deter counterfiters.
