FYI: I thought that this might be overkill and although I was a bit leary, I ordered the WGS 12L "monster-of-a-speaker" and installed it on my Fender Hot Rod Deluxe III. WOW, what clarity I am getting from that combination. Since the 12L weighs 18 pounds, it added some weight but the results make it right. When I unboxed the 12L, I thought that it might not fit but when I laid it "speaker down" on the table, it measure 5 inches up to the magnet. After I installed it in the cabinet, it still had 1 inch to spare from the chassis. The clarity that comes from the 12L is unbelievable.
