Mechanical noises at lower notes?

Sup guys

I purchased a 12'' Orion H2 12.4 off CL for an absolute steal. Specs online say 2000 RMS...this sub is massive. Orion H2-12.4 (orih2124) 12" Dual 4 Ohms Subwoofer

I'm just running an MTX 600 XD to it right now, feeding it 600rms. Sub sounds great, except on lows. It makes a weird mechanical sound when its low...almost as if its bottoming out. My gain is set a little less then half and my bass boost is exactly half. It does have a HUGE port so I'm not sure if its that. The guy who I bought it from said he hadn't used the sub for like 2 years, so could it be age? It sounds incredible, but just not on certain lows. Any help would be great.

Thanks

I'm not sure the specs on the box, but I know the sub is massive. Does the box look too big to you?

Turn off bass boost, and get a new box, that box looks like its tuned waaaaaaaaaaay too high.

I'll definitely look into getting a different box. What is considered high for you? is 38hz high?

That's a obocon prefab? It's in the low 40s. You are bottoming it out

Does your amp have a sub sonic filter? If it does set it at 34-36hz and you wont bottom out anymore. And turn your bass boost off. Although the bass boost will boost higher frequencies that are making you bottom out, its still not good to use.

It's a common prefab. They are all the same

So I found a guy on CL who has a box that he'd trade for mine. I'm a little hesitant. Has anyone heard of "Hooker audio"? its a 12'' ported box and has the logo "hooker" on it. Can't find too much on this! Anyone else know? I suppose I could go buy a box but I'm pretty frugal.
