I was looking into two cabs to go with my yorkville xs800. I have a few questions. Some of the eden cabs im interested in say 4 or 8 ohms in the spec section of the site. Are certain ones made 4 and certain made 8 of these models? How can you tell? Or are they switchable? Also, I want my amp to hit its max wattage (800) at 4 ohms. Any good single or double cab combonations I can use? It doesnt have to be eden, but my price range is $1000 or less, and I would rather buy used (cheaper!). So the mission is to handle 800 watts with 1 or 2 cabinets at 4 ohms for under $1000. Any brand, go!
