So I've got a guy who likes my Dayton III's, but wants me to make him towers that use the bottom halfs as 8" subs. He has a small area to work with, so he'd like placement in close proximity to his TV. Are there any options other than the AV8 from Adire in the sub $100 price range? A shame they don't make a shielded Dayton Quatro 8", as I really like that speaker, not to mention they're 30% cheaper. Not to mention its going to take 3.5 ft^3 to get the AV8 down to an F3 of 30htz. Also, I'll be using the PE 120 watt plate amp to power the two 8's, then his amplifier will power the Dayton III's on the top half. Thanks in advance.
