    Question RTi A7/A9 Crossover Question

    For the RTi A7 and A9, are the 7" woofers on the same channel of the crossover? Are both (or all 3) of these speakers set to below ~125Hz? Or is one above and one below?

    Thanks!

    Concerning the Polk RTi A7?s and RTi A9's.

    An excerpt from Home Theater Review.

    The midrange driver crosses over at 125Hz at 12dB per octave to two 7-inch Polymer Composite woofers.

    This is all in line with the Tech Spec page on the Polk Audio web-site which states the following.

    RTi A7 has crossover for the mid-high array 2.7kHz, 12dB/octave low and high pass, 125Hz 12dB/octave high pass
    Crossover for the Subwoofer 125Hz, 12dB/octave low pass

    RTi A9 has crossover for the mid-high array 1.8kHz, 12dB/octave low and high pass, 120Hz 12dB/octave high pass
    Crossover for the Subwoofer 120Hz, 12dB/octave low pass

    Yes I did read the Polk site. I wasn't sure if the mid-high array included one of the 7" woofers or not. Home Theater Review provides more info. Thanks.
