I'm getting a lot of mixed information regarding this... When tuning a ported cab, is it best to get the Fb to match the Fs? Or is it better to tune the cab's frequency so it goes lower than the speaker's ideal frequency? What are the advantages/disadvantages of tuning the cab so it's higher/lower/matched relative to the speakers being used? What are the possible dangers to the speakers, if any, of tuning it too low, or too high? Like a badly designed cab, this information seems as clear as mud.
