There's been a lot written about ampeg flatback 810 cabinets, regarding speakers and tone. Outside US original CTS speakers are hard to find, let alone flatbacks themselves. I have a VR and I would like to get a flatback cab but since they're so rare in EU I was thinking of fliptops replica. They're offering legend b810 and mod 10-50 speakers for that cab. I'm wondering if anyone AB'd b810 and CTS speakers? Legends obviously handle more power which is convenient if I want to use one cab with SVT but how close do they get to the tone of CTS? Are there any recordings, songs, youtube links or anything else representing that classic SVT/flatback sound?
