Sundown X-12 Prototype

[sundownz]

lets see some magic box numbers.

Once I get one in a 15" we will do it !

The X-12 will be around $285 MAP or so -- similar progression in pricing difference per size as the SA line as well.

I will also be adding an internal aluminum shorting ring standard on these -- a feature not commonly found on woofers in this category.

This reduces inductance, flattens the inductance curve, improves power delivery by lowering reactive rise, and also is a bit of a heat-sink (minimal).

Our Z v.2 (and v.3) and Nightshade v.2 models feature this as well and I decided to trickle it down

are there any vids on these yet?

We did our thermal cycle test on the X-12 with CCAW coil (final will have copper which we will also test) -- 1000 watts starting power for 5 minutes dropped to 900 across the duration so 10% compression... cranked up to ~1200-1250 and played for another 90 seconds before thermal failure.

Again, our 60 Hz thermal test is brutal and we have fried MANY other drivers in ~2 minutes at their rated power levels. It's a very difficult test. All of our subs must pass for at LEAST 5 minutes to get their rating and we usually crank them up past rated after the 5 minute cycle as well.

It's a long boring video and not quite a production model so I won't upload it -- when we do the copper production unit I will.

Are the subs tested in free air? Based on the failure rates, I'd assume so.

Yes they are -- see this SA-12 QC test video as well :

We are hitting it with as much as ~1000 watts in free air dropping down pretty low in frequency.

I just watched it and am speechless. I'm just subscribed too

Hmm. Buy the Sa-12's now, or a wait a bit for these? Don't know if the X's will be close enough in price. We will have to see.

X-12 will be about $90 more.
