My apologies Wid. Hsu is conservative while other manufacturers tend to exaggerate. I should have quoted Hsu specs along with the specs received from test results. I know you from the Hsu forum (if you're the same wid) and I know you know yor VTF2 subs well. Just wanted to let the original poster know what he'll get in real world vs. the underated Hsu specs.
