In single quantity:

Model
W20RC-38-08 8" driver $26.60 each
YAG-20 ribbon tweeter $27.50 each

Multiply by two, since Greg is promising to deliver a pair of speakers,
though I'm not sure I believe him.
Cost of drivers: $108.20, probably less than $100 if he's getting a quantity
break.

Add in cabinets. $200 for the pair since he's not making them himself.

$300 for a pair. 4 times markup.

Cost of finished product: $1350.00

This is consistent with a DIYer price of $300 a pair.
