Blaupunkt's Velocity 2Go boombox is car-mountable

Although it has been quite some time since Blaupunkt made any substantial noise in the CE biz, the audio outfit is back in full force with the forthcoming Velocity 2Go lineup. The flashy (albeit ill-favored) boombox sports a carry-handle design for those throwback moments of atop-the-shoulder sidewalk strutting, and also features a car-docking solution with the bundled straps or QuickOut mounting kit. Specs wise, the unit operates on rechargeable AA cells, touts a "die-cast aluminum" enclosure, and sports 3.5-millimeter / RCA input jacks to play nice with just about any external audio source in the book. Dubbed the "world's first mobile active speaker system," the device also rocks a built-in active subwoofer to fill in the lows, and while the Velocity2Go 5 (£249.99; $499) will get things rockin' with 80-watts of RMS power, the Velocity2Go 6 (£299.99; $599) purportedly ups the volume by four decibels in case you can tell the difference.

If the higher end model increases the volume by 4 decibels, that'd be a little more than doubling the perceived loudness.

Actually, I believe it's a 6 db increase that's equal to a 100% increase in percieved loudness.

Actually, it depeneds on the frequency. Humans are least sensitive to the bass frequencies and high frequencies, so we're more apt to notice changes in the midrange. (2500-5000hz is the range we are most sensitive to, due to the resonance of our ear canal). See this page for more info: http://hyperphysics.phy-astr.gsu.edu/hbase/sound/eqloud.html

So what makes sense is that in the upper midrange, 2-3db might sound twice as loud, but for us to make the same distinction for the very high or very low frequencies, it may require a 6db difference or more.

4 db would be a little more than doubling the power, not the loudness. A 3db increase requires twice the watts and is only an incremental adjustment in perceived loudness - 9 db is considered 'doubling' loudness.

I too thought 3db equals a doubling of the perceived volume. In any case, 4db is something you will notice.
