Can someone identify this subwoofer?

This is an RD Alpha Max motor, with a 4 spoke frame.

We built (2) drop-in recones for a guy in Sanford FL (in 08/11). I'm sure that this is one of them.

Parts used:

3" 4 layer extended length aluminum flatwire voice coil - D2 ohm

2 8' stiff progressive spiders

Sewn heavy duty leadwire

15" heavy duty cone assembly w/ wide roll surround

6" poly dome dustcap w/ PSI logo

Use it with 1200-1500w rms in 4-5ft ported and it will do very well! //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

 
To make it a little simpler.... someone there around Tampa bought the repair parts from us. They had the motor and frame already, and purchased a rebuild kit from our company to use with them.

The funky stuff around the dustcap is because they didn't use the activator with the adhesive when they glued it onto the cone.

The other guy spent almost that much for the repair parts, so yes, you got a great deal. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

 
What should this sub be at, 2ohm's or 0.5ohm's, or is it a 4ohm?

And if I wanted to get another 15'' to pair with this 15'', which 15'' out there would be best match?
