Sundown X Series 10/12/15/18 Pre-Order : ETA June 2013

[sundownz]

Our ETA is roughly the end of June on these; as always this can vary a bit based on parts supplier production times, transit times, customs times, etc. Based on our average shipping time that is our best estimate.

That being said this pre-order will ONLY be open to the public until April 15th, 2013 -- OR until a given size / coil configuration sells 50% of the quantity being produced. I do not want to be out of stock instantly so we are running this much shorter than our other pre-orders.

This pre-order is for the USA ONLY -- check with your distributor if you are outside of the USA; if you do NOT have a distributor in your country you can check with us. The below rates are shipping in the continental 48 states; e-mail us or your dealer for AK or HI pricing.

Pricing as follows :

PART # // REGULAR MAP // PRE-ORDER RATE

X-10 (D2/D4) -- $329 -- $280
X-12 (D2/D4) -- $349 -- $300
X-15 (D2/D4) -- $389 -- $330
X-18 (D2/D4) -- $409 -- $350

You can pre-order from any participating local or online dealer OR directly with us via Paypal to [email protected] -- you MUST include a note stating EXACTLY what you are ordering.

As is typical with a pre-order the sale is final ; make sure you are not placing yourself in a bad financial situation by pre-ordering. Do not pre-order if you are on a tight schedule ; the dates are NOT set in stone. An adjusted date is not considered a valid reason to request a pre-order refund. If you have ANY doubt about waiting or your financial situation DO NOT pre-order.

----------

The X series is our 1250 RMS rated line -- they feature a 3" diameter CCAW round wire coil and our new frame, spider, surround, and cone platform. Linear x-max is around ~30mm one-way by 70% BL with a total mechanical clearance of 50mm in the motor.

These woofers are designed excel in high output DAILY low frequency applications. If you are looking for a burp driver or a driver to excel on “higher” bass frequencies; this is NOT it. We will offer SPL burp style re-cone kits for them at a late date – but the stock format is not made for that.





















* Z v.4 12 on the left and X-12 on the right.




* Z v.4 12 on the left and X-12 on the right.


* New terminal blocks !






* Essentially looks like a "mini-Z" style motor... 190mm magnet vs. 220mm on the Z series / 66mm tall stack vs. 75mm tall stack / thinner steel / less expensive round wire coil vs. flat wire in the Z, etc, etc.

----------

Preliminary Specifications :
** The production models have a stiffer surround which will result in an FS about 5-10 Hz higher, higher Qts, etc. They will also have a slightly tighter gap which increases the BL a bit **

Great news to hear!

[Carbon]

Subs look great! Good deal on the preorder price as well

[Afficionado]

well....i guess i decided which 18's are going in my car!

[kmak160]

Jacob, so am I reading right that the mechanical limit (peak to peak) for the x series is 50mm? Just wondered b/c I saw that the vid of the 12" z says it has a peak to peak of 4" which would be close to 100mm. Just curious about the similarity in terms of excursion between the two lines.

thanks, Kyle

[Smurfboy]

Very nice!! But.... Where's our little 8" subwoofer? Wasn't there a X-8" a while back or something? Just wondering!

The X mechanical limit is in the motor @ 50 mm before the coil bottoms.

We have 62.5mm in the motor of the Z v.4 before coil bottom -- in our in-car video it's seeing ~50mm or so. Beyond that it get's a bit too far beyond linearity and distortion climbs; but we do still have that extra room as a cushion from damage.

Neither is linear up to that point but there is pleeeeenty of room for continued travel beyond linearity (less chance of damage, additional output, etc).

[Hunters21w]

Damn those FS are low!

[sundownz]

Complete measurements added to first post.

[Borris The Blade]

What are the enclosure specs for these bad boys?
