Hi, I have a Orange 8x10 cabinet from the 90's ... Long story short: it was a pair with AD140B custom shop basshead, only like 20 made, before making the first AD200B's (MK1 and MK2), ... And after those the serial-production AD200B's MK3's came out. I bought the pair, but sold the AD140B later because I also have a AD200B MK2 ... But, the cabinet. It's loaded with 8 EMINENCE Delta 10-A speakers, rated at 350 watts. Don't know why, the website of Eminence says those are not bass-guitar speakers but just "standard american pro speakers" ... What are these speakers compared to regulare Ampeg 810's? Most weird: in the speakers specs it's always about "vented cabs", but this 810 Orange is a totally closed cabinet. (inside, divided in 2x12's ... sealed!) All info on these speakers or the specs of the speakers for use on bassguitar are welcome! Reason I ask this, I just bought a vintage SVT and I'm afraid to blow the speakers ... (Old picture from like 2004 ... I sold the Ampeg 410HLF, too boomy ... and I also sold the AD140B).
