    No disrespect but I must agree from experience...that setup is not ideal for any placement of those speakers.

    That's a horrible room/set up for SDA's and if you are listening to the CRS+'s on top of the other speakers, you'll never hear what they can do.

    Yes they are not properly setup but can't do nothing in this place.
    Hopefully, in few months, I'll move out to a single family house and will have enough space for proper SDA setup.

    2nd best to the biggest one?
    No, the CRS+ are my favorite, then a tie between the 3.1tl and the 2b. I personally don't like the biggest ones. Sure they have more bass, but they don't sound very good, IMO. Give me the CRS+ and an excellent sub like my REL Stadium III and I'm set. Far more coherent and detailed soundscape in my experience. And I've had or heard them all but the SRS2 and 1a,
    design is where science and art break even.

    LOL...
    The CRS+ are not mine anymore so I'll be only playing with the 2B's placement. :mrgreen:

    Forget the CRS+ on top as they are there just for safekeeping now.

    But I'll work on getting the 2B's parallel to each other and back wall and move them 3 inches in front of anything else.
    So the audio rack will go out and A400's will go in that corner 3 or more inches behind front baffle of 2B's.
    That way, the left 2B will have around 2.5 feet to side wall and right 2B will have around 3 to the stairs.
    That's the best setup I can think of in that room.

    I also think using a speaker selector is not good for SDA as I think the way speaker selector uses left channel as common channel for all sets does not go well with SDA interconnect.
    So I'll have a dedicated receiver/amp for SDA's that come off of my Marantz A/V receiver's pre-out. Hmm...

    Okay, this is the best setup in that room I can come up with.
    The only thing that'll be different is the CRS+'s on top will be gone soon.

    I moved the audio rack out from left corner and pushed A400 in there 4 inches behind the baffle of 2B.
    Now both 2B's are 6 inches from back wall and front baffle is 4 inches in front of TV and A400 so they have nothing else in their level as recommended in SDA manual.
    Left speaker has 2.5 feet to side wall and right has over 3 feet to the staircase.
    Distance between the speakers is around 6 feet and my listening position is around 7 feet from each of them.

    Listened to few songs and one song in particular made 3D sound in many parts.
    Some drum beats and strings came in the middle right air space and sometimes extended to the right beyond staircase.
    Effect on left is not as strong as right but it's better than other setup I had.
    Will see what else can I do here but as long as A400's are there, it's pretty much what can be done. :neutral:

    I'd run one set of speakers up front at a time. Then just switch them out as desired.

    That'd be ideal but not enough space to have them stored anywhere else in this small townhouse.

    Forgot to ask this question.
    I checked http://www.gimpod.com/sda-id.html and the SDA-2B with real wood tops are from 1989 and supposed to have pin/blade IC.
    Mine have blade/blade.
    What does that tell?
    Polk just used what they find? :confused:

    I bought a nice pair of SDA 2B TL from forum member bluecomet 3 weeks ago (real wood version) and they do have the pin/blade IC so not sure why yours have blade/blade IC.

    Yours must not be the 1989 version.

    Doesn't matter electrically. The shape of the connector is different, but the circuitry is the same except for a missing foot of internal cabinet wire. Yes, apparently Polk used up leftover supplies on early-production units.

    Some 1Cs and some 2Bs (there's a list of serial numbers posted in several threads on this site, for example: http://www.polkaudio.com/forums/showthread.php?131691-2B-and-EARLY-1C-AI-1-modifications ) need to have a foot of wire installed in the cabinet from negative speaker post to the unused connector in the SDA socket. Then they're fully AI-1 compatible except for the shape of the connector--a blade instead of a pin.

    Not that big of a deal. Another--probably better--connection method can be made with aftermarket terminals such as speaker binding posts, or the "Neutrik" connectors, etc. Sky is the limit.

    Okay. This site has 1989 as real wood. http://www.gimpod.com/sda-id.html
    Same with polksda.com.
    I didn't see other year for real wood version.

    I haven't opened it to check crossover but it works so no problem.
    I was just curious.
