Seas CB17RC Note: By clicking the images you will get a bigger image (not all).

The Watt V and V.I uses the Scan-Speak 7" Carbon Fibre Unit (18W/8545), the previous incarnations all used the Seas CA17RCY doped paper cone driver. The closest current equivalent to the CA17RCY is the CB17RCY. As previously discussed, this was my choice.
