Pregnancy and breast-feeding: Using lactobacillus during pregnancy and breast-feeding is POSSIBLY SAFE. Lactobacillus GG has been used safely in pregnant and breast-feeding women. But other types of lactobacillus have not been studied during pregnancy and breast-feeding, so their safety is unknown.
Best Answer: Subwoofers of almost any brand have high enough frequency responses. I mean, take for instance the alpine type r. Its frequency response is 25-500 hz. Now it will probably never play that high, the highest you will probably ever need it to go is 120hz and thats for a bass test song. Quality subs deliver low bass, which is what most people look for.
As long as you know the amplitude tolerance (+/- 3dB), the frequency response range or width tells you how high or low the speaker goes. A speaker rated as 20Hz â 25kHz +/- 3dB will play lower bass and higher treble sounds than a speaker that measures 40Hz â 20kHz +/- 3dB.
