Its an all black, CF Capped, MONSTER 18" subwoofer. It will do very well in ported applications from 4ft up to 8ft with a mild tuning (somewhere between 28 and 35) for daily ground pounding.
It has a very healthy 3.2" p-p of excursion, a fairly low Fs, and will drop low when asked to!
Will withstand roughly 2000-3,000w rms depending on the user and the application.

NOW HERE'S THE COOL PART:
The black 18" 6 spoke basket has 1.5" holes milled into it to allow for direct access to the bolts holding the basket to the motor. These bolts can be easily removed with a 10mm wrench (ratchet wrench is MUCH easier), allowing the entire top assembly to be removed and swapped to another motor, or to allow for a different top assembly to be mounted to the motor.
The removal of the basket isn't something that I would call "quick", but it's definitely do-able. I've taken it off and on quite a few times now.
I've tallied up the total cost for this subwoofer, pricing each individual option, and the value of the subwoofer would come out to be right at $500.
The Konaki motor is arguably as good or better than most large sub motors out there now. It has a large enough gap to allow for an 8 layer coil, large 220mm magnets, and tons of cooling vents in the motor. Its just as strong as most, and cools better! It's a VERY proper choice for a high output daily subwoofer like this. I could have used a Nightshade or RE MT motor for this woofer, but the Konaki is a better choice IMO. It took it off a built, but brand new 1207A.
If someone is interested in just the top assembly, I would consider selling it without the motor! The top would work with lots of different motors! It would be just great on RE MT's, Sundown Nightshade, Fi BTL's, etc etc etc... basically anything with a large enough gap, a standard bolt pattern and a top plate within 2mm of 25mm in height!
These are ALL BRAND NEW parts. This is a BRAND NEW subwoofer. It's got tons of add-on's and upgrades above most anything available right now. If you need a ****** 18" that will drop LOW, this is it!
It has a PSI logo on the bottom of the motor, and a blank cap. I can put any of my logos on the cap, or leave it blank. I can also add a custom logo per your design for $30!
