EARTHQUAKESound PUMP-12 12-Inch Horn-Loaded, Dual Passive Radiator Module

Q: is there a bolt to add/remove mass for tuning purposes?

There's aren't. But you could glue weights to the back

Q: can you add weight to these to change the tuning? or can you not get to the back of these things to add weight?

Instructions do not mention adding weights at all. From my experience-you don't need to.

Q: I have a high end 15" sub in a sealed subwoofer box. Is this something that will enhance the sound with my components?

I do mid-and high end drivers. One Wrath 15 pounded the piss out my car. Sealed at 2 cubes and added one cube for the radiator. I liken it more closer to the output of a 4th order box than a ported one. No port noise is great and probably better in a SUV or Hatchback. Still sounds very clean in my trunk. Follow the directions and you'll be a very, very, happy customer. Building a new box right now with 2 Earthquake 15dbxi's and two Radiators. So far, I've made 2 other boxes with these Radiators. The other box has 2 DC Audio Level 3s tuned to 32hz and one radiator in that box also destroys the car. I make sealed and ported enclosures but maaaaan these horned Radiators dominate!

Q: How is this tuned for lower frequency? I don’t see holes for weight?

Just add 9x14x14 to your box-no weights needed like a regular radiator. It actually feels like it lowered my tuning from 35 to 25-28hz things shake so violently in the car.
