I understand from a bit of research that the Dayton isn't bad, especially considering the money. If there is the potential for spousal abuse and you just want to catch a whiff of bass, it might be the ticket.
However, we must also bring the dreaded upgradeitis into the mix. Once you begin to experience quality bass, I'd guess the STF-2 is gonna look pretty good to you and that means more on top of the $130. I'd suggest that you get the HSU and just turn it up a bit at a time until the wife gets used to it. Watching LOTR with burly LFE will get mama over the fence quickly.
Of course the basic guy option is always available - sell the wife. Then buy a big honkin' SVS and move the house off the foundation. Man, you can almost smell the testosterone in the air.
