Love my Dayton SUB1000L (10”) and I bet the 1200 is better, and they are a fantastic deal. One other suggestion: If you really want to go low for a good price get any Hsu VTF model. I have the VTF-2 (12”). It easily goes subsonic, loud, and clean, and also comes with a CD with 16Hz organ notes to prove it. Downside: It’s big.
