I think these are the two nomenclatures for the drivers in my SDA 2Bs. What is the difference in the drivers?

    2B's should have MW6511/MW6503 combo. SDA2a's used MW6510 x 2

    Could be, I am not at home right now. Anyway, what are the differences in the drivers? Why did they use two different ones?

    Gotcha, thanks for the info. Reason I am asking is that while I am having Trey do mods on my 2B boards, I was going to hook up my old RTA 8T crossovers to the 2Bs so I can still listen to them.

    The drivers in my 8Ts were the same as in the SDAs. They even had SDA stamped on them.

    Yeah, that's not going to work. The crossovers are not the same.

    Are you sure they are 8t? The RTA11t/15t used MW6510. I didn't think that 8t ever used mw6510 I've been wrong before and will be again

    With the exception of the 6503, the drivers are the same as in the 8Ts. Why wouldn't it work? Because of the 6503s? I know it wont have the SDA effect, but it will do until I get the mods back.

    Yes, they had two 6510s and an SL2000 in each speaker.

    The crossover circuits are completely different.

    Still dont understand. The drivers can't tell what xover is driving them. It will be like listening to 8Ts but in a SDA 2B cabnet.

    Sure they can. The parameters of the crossovers and the drivers are designed for each other. Change those parameters and the sound changes for the worse.

    No, it will not.

    No, it will not.
    But they are the SAME drivers. With the exception of the 6503, which was my original question.


    I'm gonna try it. will post

    MW 6503 1.820 5.24 N 3.550 E - 3N/M 6.540 Ohms 29 Hertz

    MW 6510 1.390 6.32 N 3.410 E - 3N/M 6.570 Ohms 31 Hertz
    MW 6511 1.405 4.34 N 3.496 E - 3N/M 3.130 Ohms 29 Hertz

    the 8t used the same ohm drivers. The 2b uses 1-4 and 1-8 ohm which come off two separate locations on the 2b XO that use the interconnect. one location off the 8t for both drivers

    I'm lost on the parallel or series here.

    Since you are determined to try this I would not push them very hard as damage to the drivers may result.

    No, they are not. The 2B uses one 6503 and one 6511, not to mention the difference in the parallel/series wiring.

    Will you get sound, yes. Will it sound just like listening to 8Ts but in a SDA 2B cabnet, hell no.

    Well, just hooked it up with the new RDO-194s. Sounds good. I am using the wires from the 8T xovers. Just plug and play.

    The only caveot is the 6503 driver as opposed to a 6511. Based on the info in this thread, sounds like they are both 6 ohm.
