whats a FI bl 18 worth used

[richardparker 0]

I want to know how much a Fi bl 18 is worth used.I dont know what options it has because the person I got the sub from told me it was a BTL and I got a BL. It's in a box tuned to 32hz with a 1600w hifonics brutus pushing it fine with no distortion.I'm might be looking to sell ,just want to know the going rate before putting it in the classifieds.Thanks
