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.
A subwoofer is generally not a stand-alone component. Since a sub is typically used to produce frequencies from 20Hz to 200Hz, other speakers have to handle the rest of the audio spectrum (200Hz to 20kHz). It is best to add a subwoofer to a sound bar, floor standing speakers or a full surround sound setup.
