Prototype Z v.3 Testing

I may tool new surrounds for the 10, 12, and 15 -- currently the roll is equal to the SA series. Some torture testing is in order

Thinking more like the high tall roll surround that appears to be on the 18's?

Possibly... depends on if the current surrounds pass my torture test. If they do I won't change them -- if they don't I will tool up a set similar to the 18"

They do look mighty fine

Playing a Bass Mekanik track that drops down to 20 Hz. We are using an SAZ-2500D @ 1 ohm on the woofer -- the first part of the track shows the sub playing at maximum un-clipped volume and then we push it into clipping towards the end to show how much is TOO much sub movement.

You can actually hear a bit of "buzzing" right at first after I turn it up for the second run -- that is audible clipping.

This is what I don't like about the black paint finish :

It's not noticeable on the SA line with relatively small back and top plates -- but when you get plates this thick it shows up.

The black paint also sometimes gets messed up a bit in shipping as it occasionally is not 100% cured and the plastic packing bag will mess up the finish by leaving crinkle marks on it.

Minor, yes, but it bugs me... especially on a larger and more expensive driver like this.

is this climb cutting or conventional cutting? climb cutting will give you the best finish on this machining. another trick you can do i once its machined out, have the cnc come back in with a longer cutter, and go around it in one pass taking off .0005 of stock, that should clean it up nicely.

also, are you using 2 flute cutters, 4 flute cutters, cobalt, carbide? what is your rpm and feed rate?

oh shit....

reminds me of my manufacturing processes and CAM classes, haha

A few pre-production changes are going on...

1) I am changing these to 8-layer flat aluminum coils from the currently tested 4-layer round aluminum coils.

2) This will raise the cost to about the same as the Z v.2 price now, so they won't be cheaper now -- these coils are about 2.5x more expensive than the 4-layer round units.

Good news is they provide enough benefit that I decided to go this route on the driver for the stock coil I am sure nobody will be let down by the added benefit.

Otherwise the pictured units with chrome motors are what will be produced.
