Welcome to TalkBass and the Rumble Club! The extension speaker output on the rumble 500 is 8 ohms minimum. The Rumble 210 Cabinet is 8 ohms. Two Rumble 210 cabinets would be 4 ohms which is less than the 8 ohms minimum for the Rumble 500. That would be a good way to blow the head of the 500!Hi All, I've tried doing some research but I'm not finding an exact answer to my question. Is it possible to connect a 500 combo to two 210 cabs? So it's essentially a 6 foot tall triple stack? Thanks for any help.
