SDA 2 Passive Radiators

Is the difference between SW120 and SW121 purely in the weighting (pucking)? If so, I'm assuming this is to balance the driver compliment with the desired bass response, no?

The reason I'm asking is, since the Monitor 11's were added to the mix here, audio-filly is in love with the PR's in them. Her assessment "the SDA's have a boomier, sloppier bass and the 11's have a tighter, punchier bass." I have to agree with her, although I still much prefer the overall musicality of the SDA's.

Has anyone ever tried a SW120 in a SDA-2B? No screams, flames or accusations of sacrilege, please - just asking.

    Mike,

    Swap them around and see what you think. Personally, I don't think it's the PR making the difference.

    Hey Jesse,

    I'd considered doing that on the sly with the 11's. The PR's in them are, according to the manual, D-1200-A's. They look identical to the SW-121's except for the "puck". If Sandy (audio-filly now thanks to Tour2) can tell the difference, I'm just going to sit back and let her manage ALL the audio gear! :D

    On a side note, it's interesting that Polk makes no reference in their online info about the Monitor 11's. Marty, the previous owner, called Polk and was told by someone on the other end of the phone "we never made 11's". That's when he jumped in here. The cover of the manual (which he posted a pick of in his thread) reads:

    Model 11 Real-Time Array
    Reference Monitor System (R.T.A. 11)

    Mike,

    They seem to be somewhat of a forgotten child, but rest assured they are the real deal.

    Oh, if you had ideas about buying replacement PR's from Polk, forget it, they don't have any.

    I just (today) picked up two SW120's designed for the:

    SDA 1
    SDA 1A
    SDA 1B
    SDA 1C
    SDA 2

    . . . . which all have a larger cabinet volume than my SDA-2B's that came from the factory with the SW121.

    I'm going to do a swap and listening test later this week and will post.
