That is very true. The volume level difference between 14 and 22 watts is quite small. Gotts assume the significant difference is more due to the speaker system itself.


Yes, the speaker system also makes a big difference, and reading the specs should give the prospective buyer a good indication just what to expect.

I found it hard to hear the PSR speakers in a restaurant with low noise level, so even a medium loud bar would be way too much to expect the "home " system to compete with.

PSR on board speakers are for home use only.
