View Full Version : what sub is this - box recommendation for 15"

02-28-2013, 01:00 PM
All i know about this 15 is that it has been re-coned by robotics underground and it has a double stacked magnet. unfortunately thats all I know. Does it look familiar to anyone? I need to build a slot ported box for it. daily driver. Looking for educated ideas on how big to make the box, and port. Thank you.

Can you pull the boot off and get a few shots? Did you buy it from robot or from someone else?

I just bought it from a guy who told me nothing about it. I sold it to my friend and were tryin to make a box for it now. The first box was 4.5 cubes with 44 sq in of port and he says its not loud off a kicker zx1500. so i cant take a pic right now but theres a double stacked magnet under the boot. should his next box be smaller and more port area?

4.5 Cubes should be big enough for that 15, given you don't know what it is actually. Try more port area. And more cow bell.

I would try 4ft3 net volume and around 60in2 of port area and see how that works out.

Can he cover up the port and put in 2 - 6" pvc ports?

anyone? rather than just building a new box. and can the 2 ports face opposite sides of the car?
