Can Anyone From Fi Explain?

[SKEEMASK 3]

What is the Induct Heat Ring and what is its pros/cons?

Smart A time

Pros - it is available to use on BTLs and i assume it's another cooling type option but not a fact yet.

Cons - It costs money.

Is it some sort of heat inducing ring to pre-heat the sub for people who live in extremly cold enviroments? HA HA! I have no idea what it is, but I am curious to find out what it is. Bump for an answer.

Its a machined aluminum ring in the gap that lowers the voicecoils inductance (allowing it to play up higher and have a little better overall transient response). It also reduces the volume inside the magnet gap of the motor increasing air speed with the cooling as well as allowing the coil to kick off heat to a more receptive thermal mass than magnets...

Thanks,
