I have a pair of 1 year old Hawthorne Audio 15" OB "Augie" bass drivers. THIS LISTING IS FOR THE DRIVERS ONLY.
Here is the Amazon listing for Hawthorne Audio. As you can see, for two of these drivers, + shipping you will pay $500.
https://www.amazon.com/Hawthorne-Audio-15-Augie-SI-OBA-15/dp/B01C7HVG1A/ref=sr_1...PRICE: $300 + Free Shipping (CONUS). No Paypal fees if send via "friends & family."
I used these VERY sparingly for bass augmentation when I had my prior speaker systems in play. My new loudspeaker have dual 12" bass drivers so they have not been used for the last several months. They are in like new condition, no blemishes.
They will be packed with care to ensure a safe arrival.
