I have a simple question. I am going to build one of these for recording: http://www.amptone.com/diyisobox.htm I greatly prefer the sound of 16 ohm loads over 8 ohms. I was thinking I would get a 2x12 and use two 8 ohm V30s in series. But how would the sound compare to using a 1x12 with 1x16 ohm V30? Only micing one of the speakers here with an SM58. High gain guitar amp. Thanks!!
