Tying a subwoofer into standard desktop speakers and electronically lowering the pitch (so that it produces deep sounds)
For fun I decided to take apart my desktop computer speakers and convert them to a portable iPod speaker. I have already found a way to convert it to DC power so that I can integrate it into a portable "boom box". I also have a subwoofer that I would also like to build into the boom box but the sound when connected is rather high in pitch. Is there any I can do electronically to lower the pitch so that the bass is more pronounced and deep? Thanks!
