Jake, could you explain the differences between this in the Nightshade, this had more motor force, but the NS is rated higher power wise? Is it just different soft parts?

Every part except the frame is different from these to the Nightshade. You are confusing this with the NS-X.

These have less motor force than the Nightshade and a lower power handling. These woofers are more of an "SQL" woofer vs. an SPL sub in the Nightshade.

These have a different cone, surround, dust cap, coil, spider, tinsel leads, motor, etc than the Nightshade

Adding the T/S specs to my box building software. The sd looks incorrect. It can't possibly be 83 square meters.

What is the Xmax and rough estimate on magnet dispalcement?

What is the Xmax and rough estimate on magnet dispalcement?

X-Max by overhang = 18.75mm

Linear x-max by 70% BL is closer to 22mm

Displacement is about 0.19 ft^3

My guess was pretty close. I used 21mm of linear xmax and a displacement of 0.19 ft^3....

If you are looking to do a big build with these talk to me about 4+ !!!

Two more days.

Today is the last day guys, make sure you order some before its over!!

Is that Sundown Amplifier I see in the floor a special edition one I havent heard about yet or an old model? Never seen such heatsink design before.
