Searched and saw this posted a few months ago but the deal is back,
HSU has the VTF3-MK3 (black) discounted to $629 plus shipping for 4th of
July sale ($70 off)
Great subwoofer and HSU slowly transitions between woofers on sale, bought
one for myself to swap out for the STF-1 since i missed the sale in April.

Also the VTF-2 MK3 (black) is on sale for a little more affordable price of
$519 though I would recommend the VTF-MK3 if your going to spend this much
