I had a buyer with good feedback claim a woofer was blown on a pair of Harbeth SHL5’s. The speakers were perfect when I shipped them and my buyers claim seemed fishy, so I refunded his purchase and had him ship the speakers to the US Distributor (Fidelis AV) for inspection. Fidelis said the speakers were fine, which confirmed my belief that my buyer just wanted to test drive the speakers. With email proof from Fidelis that the speakers were operating properly, I told the buyer he either had to take the speakers back or I would leave him negative feedback. He quietly agreed to buy them back when Fidelis support allowed me to call his bluff. What a dishonest Jack a--!
