I bought a delta pro 15" speaker on ebay a week ago. Paid right away, and the seller got it to me fast. got it on wednesday. As soon as I installed it in my cab, the think started farting and distorting like it had a 4 inch rip in the cone, but I couldn't find anything. It would also cut on and off where no sound would come out at all. I wrote the seller and told him I was not happy, and I blamed the problem on poor shipping, the box it was in was too big for it, and it bounced around the inside of the box all the way here. The item was used, and the ad specifically said "AS IS", so I figured my $81 was gone. Even if he offered a refund of the seling price ($51) after paying shipping both way I would still have just $30 back in my pocket. The next morning, what do I find in my inbox but a $100 refund from paypal. The seller not only gave me back my original $81, but gave me an extra $19 to cover returen shipping. I was totally blown away, this was the last thing I was expecting. I didn't even ask for a refund because I assumed he would fall back on the famous words of "as is" turns out the cutting out problem was caused by a bad solder joint on the positive terminal, and after I moved it a little it seemed to work fine, even the farting noise went away. I went ahead and sent the speaker back because I wasn't sure that the noise was related to the bad sloder joint, I didn't know if it would come back in the future. Have you ever heard of a seller so quick to give a refund, and be willing to pay shipping both ways? also, has anybody seen a speaker sound completly shredded, but then be fine an hour later?
