    Did you buy the ones off of CL in VA? If so they are SDA 2b studio model.

    Here are the specs for your SDA 2b's they are the studio version.
    http://polksda.com/pdfs/SDA1C.pdf

    SDA 2a had two MW6510 mids and one sl2000 tweeter also. Ht was 39 1/2 inches a little taller than your studios's I believe.

    Your SDA 2b's are a fine sounding speaker.

    To answer your other thread be careful using the yamaha AVR i.e. keep the volume very low. You need to get some high current power to the SDA's. Seperate amp will do the trick.

    Hope this helps. Tell your friend the 2b sounds better than the 2a;)
