In studying crossover diagrams posted in the sticky by DK I see that the 1C and the '87 model srs2 use the exact same x-over and drivers. The SRS2 uses a 15"fluid coupled passive and a much larger enclosure with different driver orientation than the 1C.
What does fluid coupled mean in terms of the radiator. I assume there would be much better bass extension with the SRS2. is this correct? Does anyone have any more specifics as to the cabinet volumes and any of the differences in these 2 designs. Are there any other differences that i am missing? And finally how do the SRS2's sound compared to the 1Cs (I would assume the primary difference would be in the bottom end due to the cabinet and radiator, but would also expect some differences in mid-range presence and sound-stage due to the driver placement).
