Gents, I've used the search function and I only found threads from when Marshall initially put the 425 cabinets on the market. The 4x12 came with these speakers- and the 'C' supposedly stand for 'collectable'......or does the 'C' stand for 'crap'? Have any of you guys used these for longer periods of time? What's your take on them? I'd like some opinions if you have some to share. A guy wants to trade me his 'Jimi' 425A Cabinet (purple) with the G12C stock speakers, but I don't have any experience with the speakers..... Thanks.
