It might have a little more in it - I have not hit x-mech limits on the subs just yet.

They are on pre-sale now if you go the Sundown Audio sections on SSA, SMD, or CACO forums. Priced around 100 dollars each.

They will be shipping (ETA) in February.

That's a pretty nice price point for a stout driver

SPL per watt testing (total power... divide by 2 for each woofer):

330 watts = 143.9 dB (HU @ -10 sub control)
430 watts = 144.8 dB (HU @ -9 sub control)
580 watts = 145.6 dB (HU @ -8 sub control)
750 watts = 146.4 dB (HU @ -7 sub control)
990 watts = 147.2 dB (HU @ -6 sub control)
1290 watts = 147.8 dB (HU @ -5 sub control)
1710 watts = 148.5 dB (HU @ -4 sub control)
2260 watts = 149.1 dB (HU @ -3 sub control)
3010 watts = 149.9 dB (HU @ -2 sub control)

Going to try -1 shortly after they cool off... I dropped a 4500D in the Jeep instead so I am a bit more flexible on power if I decide to put something different in for any upcoming shows. So I have the potential to put more power than I have before on them now.

-1 was too much with the 4500D -- woops [Smile]

I have a few tweaks to production that should allow that sort of power on burps. Still didn't kill it thermally, though !

FYI... I sheared the aluminum former in two -- didn't break any glue joints or thermal the coil. I suspect I bottomed out my triple joint ring on the top plate hard enough that the shock broke off the former. Of course I had 2000 or so watts per sub at this point too -- something has to go eventually.

I will add a LITTLE more rearward clearance on production models so even doing that will be slightly more difficult.

Jesus, good price, good looking woofer, and handles a ton of power, I bet these will be flying off your floor so fast they won't be in stock ever. Good job man!!

Put me on yer mailing list! I will be using 4 DD 8's in my Kruiser, soon as I can afford the rebuilds!
Would like to compare these against the DD's!
What coil configurations will be offered?

D2 and D4 -- D2 being a thicker wire will have a bit higher BL^2 / RE (motor force).

Sundown SA-8 (D2) / DD 1508 (D4) :

I've had alot of folks ask me about how they compare to the DD 1508s so I bought a pair of 1508s to measure T/S specs on since I cannot find them online :

The DD 1508 is WELL broken in as it is used.

Sundown SA-8 (D2) / DD 1508 (D4) :

RE: 3.28 ohms (series) / 7.48 ohms (series)
FS: 41.6 Hz / 44.6 Hz
Qes: 0.513 / 0.844
Qms: 6.606 / 9.217
Qts: 0.476 / 0.773
Le: 2.778 mH / 6.446 mH
Vas: 3.285 L / 4.672 L
BL: 17.138 N/A / 17.78 N/A
Cms: 83.341 um/N / 99.97 uM/ N
Mms: 175.654 g / 126.977 g
Sens: 78.476 dB @ 1w/1m / 78.77 dB @ 1w/1m
BL^2/RE: 89.5 / 42.26

I may drop the 1508s in my box and try them as well if the cut-out is comparable.
