Great sound possible using a Subwoofer?

Nick read"what freq.do tube amps loosen up in the bass?"

Nick, play a test VCD with third octave pink noise, listen in the listening seat, and see if your pseakers really are flat to 38 Hz in your room. They might not be.

That's CD of course, sorry for the typo.

If your speakers are flat to 38hz, you should have absolutely no problem with bottom end weight of your program material. There are really very few instruments which reach that low, anyway. Two are the piano and the pipe organ. If your system goes that low, it should be rattling the floor. Also, rock music, while often filled with a lot of bass, is usually not very deep. Most rock music is rolled off well before 40hz. A good CD for testing the bass capabilities of a system is Sarah McLachlan's "Surfacing". If track 2 does not shake the floor, your speaker manufacturer is lying to you, or you have some bass extension problems upstream in your system.
