Cool new part for Sundown Z v.2

[sundownz Pro Seller]

This part is a spacer / shorting ring / heat-sink for our upcoming Z v.2 model subwoofer. These are made right down the street from us here in Troutman, NC at a family owned machine shop. Great guys down there... they also did our aluminum Nightshade v.1 pole plugs.

Just got these in... testing so far has not included them but they will be standard on production models.

A few pictures :

Should I powder coat them or leave them raw aluminum color ? I like the raw aluminum look myself.

Thought I would share - I'm excited to see all my new parts coming together for the new line!

Aluminum looks great. How much a benefit will you get from these?

It is primarily a shorting ring and a spacer (I will post pictures of why I need a spacer when that part is done) -- a shorting ring stabilizes eddy currents and reduces inductance. Jon over at AE speakers is a big believer in them at writes alot about them on his site :

He takes it another step and also uses a copper pole sleeve -- I didn't do that with this driver due to the necessity of widening the gap and losing some motor force.

The heat-sink gain, IMO, is not tremendous... but is another bonus of having aluminum near the coil.

Nice, Jacob. I love the raw look.

Have you considered using a shorting ring under the top plate, as opposed to a sleeve, so that you don't have to widen the gap?

I like the raw look too. Will you be making some 12" in the new v2 models?
