    Also, 100Hz gives you a full octave transition above the -3dB point of those LSi9s, which would definitely prevent any kind of frequency gaps caused by the speaker's natural rolloff as it transitions to the subwoofer. That said, the common knowledge is that any crossover above 80Hz has the potential to cause localization of the subwoofer (i.e. you can hear the bass coming from the location of the sub instead of from the speaker). Using the half-octave rule above, 80Hz really isn't a bad crossover to use on the LSi9, especially since you'll get some extension below that in your room (whereas the specs are anechoic). Keep in mind, however, that the LSi series really demands external amplification that is 4 ohm stable to sound its best, so any advantage you may be hearing by setting the crossover to 100Hz is likely just because you're alleviating the power it takes to produce the lower bass, giving it more headroom for mids and highs.

    Ok I follow that. Today I merely turned the subs up a slight notch for a a "louder" bottom. But at 100Hz the subs do not seem "localized". I'm thinking about the volume trim on the receiver, it's flat, but might bring it up a notch or so, Will this affect the external amps:confused:

    i wonder hows this setup(RTIa7/RTI10) compare to RTIa5.
    i hear almost no bass coming out from A7 in futureshop (doono wut crossover they seat to, ymaha 6150), and A5 sounded a lot better, and brighter.

    im wondering wut frequency r these 2x 7 inch woofers taking care of?
    the reason im asking this is i notice some weakness in low-mid from my RTI6, also by some other polkies. Im wondering if this something woofer can handle better.
