The sub-woofer thread is īriefly recapping thunderpick's first post about his speaker: 'I picked up a 15' Pro Studio speaker for free, it is a RM-065-241B 1999/12 SA 8 ohm Welton is the manufacturer, subsid of sony but Ill be darned if I can find didly. He has been posting on an old thread originally about using sub-woofer speakers for this purpose, and I think this is causing confusion. I'm taking the liberty of starting this thread to help thunderpick see if he can use a speaker he got free for bass guitar.
