"Even six inches of glass fibre has little effect at 100 Hz, where a 
quarter wavelength is over 2 feet (860mm), and so adding absorbent 
material has virtually no effect in the lower bass region in the 20–50 
Hz region, though it can bring about great improvement in the upper bass 
region above 100 Hz."

tu skaityk, skaityk, skaityk. galvok. ir maziau rasyk.
o kai suprasi, kad masinos gerumas matuojamas ne tuo, ka sau maksimaliai 
isgali leisti drozti tiek, kiek esi priverstas gyvenimo, o tuo, kas 
daugiau teikia malonumo, galbut sugebesi pritaikyti MB S-class vs. fiat 
multipla palyginima ir audio srityje. dabar tai esi uzsispyres bukis ir 
dar su didziuliu nepilnavertiskumo kompleksu.
