I have 2 sets of hertz ml280s I'll be getting rid of. They're used for about a week on a us Amps usa 100.  I'm asking 180 per set plus Paypal fees shipped to the lower 48. I only take PayPal and I used to have 100s of references years ago on here, maybe some older members will remember me. Best way to get ahold of me is through text message 423 506 3767
