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.
First, look at the frequency response at frequencies less than 5 Hz. The response is close to 0 dB (10^(0 dB / 20) = 1.0). This means that the motor's output will look like the motor's input. If you input a 2 Hz position command, this motor with this control system can follow it with close to identical amplitude.
