.....a most worthy report, Speakerman....surely there is an amount of readers at this site who have young families and very limited budgets for home audio, and virtually all of us have been there....from reading at this link, I'm not sure the 15 dollar off coupon goes past tomorrow, with tomorrow being a legal holiday, but a quite decent 150 watt 8-inch powered sub with 8-inch passive radiator for a century note ($100) that includes shipping, should fit the bill in grand style for a limited budget....sure, two for $200, delivered.....

.....here's another one that would be a quality deal for limited budgets....this is a "pair", not one, also with free shipping.....
