Reopened because things have come up in life, leaving me with 0 time to try to build these.

Bought these last year with the intentions to build them up into sealed enclosures, they have been sitting in my living room since then, i have to time to work on them now.

$450 is the price per sub, they are brand new, never installed into any enclosures, i did take them out for testing when i received them.


That is the same product you will be getting

Now Shipping, $450 each, paypal confirmed address only. to con US 48 states.

PICKUP PRICE- because i get to save on shipping, and hassles, $300 cash each.

Prices are firm and non-negotiable.
