Hi. I'm building a small stereo tube amp PCL82 based (used on old TVs audio) Just 3W per channel and no deep bass nor very high frequencies. The idea is to build a nice retro-look wood cabinet with its own speakers, kind of a "retro futuristic boombox", old school shellac finish. 
I get two (very) cheap 4'' speakers (one per channel) and I need to know the minimum sealed box volume of each cabinet.
Of course, no online data available for the speakers so I tested them with the LIMP software, added mass method (a coin of known weight). These are the output values:
Fs = 133 Hz
Qt = 0.01
Qes = 0.01
Vas = 4.82 liters
With such a small Qt and my not-so-high expectations, which should be the minimum size? Could be smaller than Vas?
Thanks in advance.
