I have three pairs of drivers for sale.  All are proven drivers in an OB configuration.

Tang Band W-1808.  These were my go to for a number of years and most recently used them in a second system.  These go for $360 per driver on Parts Express Site.  Selling the pair for $360.  Original boxes.  Note: one of the whizzer cones is slightly bent.  Barely noticeable.  I can send pictures.

Eminence Alpha 15A.  These were used in the same OB configuration with the 1808s.  Again, a classic OB driver.  $150 per driver on Parts Express.  Pair for $150.  Original boxes.

15" Hawthorne Augies. These are an upgrade from the 15A and a great sounding bass driver.  Not as efficient as the 15As and require separate amp.  I ran them with Crown 1000.  Original boxes.  $200 for the pair.

I also have a Dayton Audio AMT4 Pro which is a great tweeter and with the open back creates a airy soundstage.  I am currently using these but will sell in a OB package:  1.5" baltic birch baffles that most recently housed the AMT4, W-1808 and the A15s.  I also have crossover specifically built with high quality components.  Ready made OB solution.  Expensive to ship but if someone is in the greater Chicago area, we could pick a spot to meet up for delivery.

Buyer pays shipping and paypal.  I also do, Venmo, Zelle, etc. for no fee.
