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.
For example, the JBL 4688 TCB Subwoofer System, a now-discontinued system which was designed for movie theaters, had a frequency response of 23â350 Hz when measured within a 10-decibel boundary (0 dB to -10 dB) and a narrower frequency response of 28â120 Hz when measured within a six-decibel boundary (Â±3 dB).
