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.
I realize frequency response is technical gibberish to a lot of readers, so now that I have addressed your immediate question I will discuss frequency response and what it means to anyone buying audio gear. Frequency response is the range of audio frequencies an audio component can reproduce. Humans can hear between 20 Hz and 20,000 Hz, with 20 Hz as the lowest bass and 20,000 Hz as the highest treble. You can feel frequencies below 20 Hz, but not hear them.
