Z v.2 Back In Stock

The Z v.2 woofers are back in stock.

There have been a few revisions made :

1) The top shorting ring has been removed -- but the internal ring was upgraded from aluminum to copper.

2) The coil windings changed from 4-layer flat aluminum to 4-layer round bifilar copper -- this lowers Fs a bit and I tested no loss in efficiency at lower power and a small gain at high power. Coil is a bit more robust than the aluminum was as well due to additional mass. Copper also has a lower thermal expansion to accommodate the Z v.2 tight gap. All in all it makes the driver more tolerant to abuse.

We still have the 4-layer flat aluminum coils to match other subs on re-cones... also, the motors can be mixed as the shorting ring material change is not a huge difference.

I suppose -- but I'm not changing the name as it's close enough :) Just a little improvement.

Does this include the 10"?

I can make 10s but I don't want to yet... still working on the spider specifically for 10s.

If someone REALLY wanted one it could be done.

Okay there are a few specs for the Z12 V.2 that I haven't found that I need, mounting depth, power handling and price
