Speakers with deep base


Looking for a speaker that will do deep and abundant base. Must have, at least in my view, at least 12''+ drivers. Thinking 5-7k in budget.

My room is 20 feet wide and 60 feet long.

Other restrictions on gear are really not an issue. I can buy what I need.

Thanks Ken

Good luck! Towers with sub woofer rules the industry now! 1970's rock and roll bass thumpers don't exist anymore!
