How it made it's way (and why) into my sub I'll never know. Thanks for your patience all!
P.S. I'll try it out back there anyway - might be good for port noise (should there ever be any)
That's pretty funny. My mind also went straight to something like a stand, due to the spikes, but indeed this is definitely a display of some sort. eBay is fun.
