I experimented with speakers today and to my ears, the old Eminence V128 was the winner. I love the Scumback J75 as a close second place speaker. The V128 is a little softer on the high end, but has a firm upper midrange and firm, tighter low end. It's a wonderful speaker for a 1x12 open back cab. I will make another clip tomorrow...
But, the Scumback loaded Splawn 4x12 cab is still the king for louder soundstages..
