Setting LSi 9's & LSi C to large in HT setup.

Guy is this a bad idea? I set the x-over points on the low end @ 250hz. and left the others where the receiver had them at factory.
so far they sound better but I'm worried to run them at my normal listening levels. I know the specs for the 9's say Overall Frequency Response 38Hz - 27kHz, Lower -3dB Limit 50Hz, Upper -3dB Limit 26kHz and the LSi C says Overall Frequency Response 40Hz - 27kHz, Lower -3dB Limit 52Hz, Upper -3dB Limit 26kHz.
So where should I set the x-over point at on the receiver with the front sound stage set to large?

    Try setting your crossover at 80Hz & set all speakers to "small". Chances are that you'll really like the way it sounds.

    250hz on the sub? That is awful high. With those speakers the sub/fronts should both be at 80hz. For music you may want to go with 40,or 60hz. 250hz is for crappy little cubes.
    Please. Please contact me a ben62670 @ yahoo.com. Make sure to include who you are, and you are from Polk so I don't delete your email. Also I am now physically unable to work on any projects. If you need help let these guys know. There are many people who will help if you let them know where you are.
    Thanks

    Can the SVS even play that high?

    I agree with the others, definitely stay around 80 Hz.

    The crossover on your sub should be set as high as possible (250hz should be fine). The crossover in your AVR should be set at 80hz with all speakers set to small. (experiment with crossovers above and below that setting as well.)

    This recommendation is based on a normal setup of sub hooked to LFE out on your AVR and speakers hooked to the speaker outputs.

    Now for your setup , 80 hz is just perfect cause the bass-reflex, frequency response 50-26,000 Hz, Ring Radiator tweeter, dual Dynamic Balance drivers, ARC and Power Ports, real wood veneer

    Setting all speakers to small would most likely set them at an XO point of 150+. You need to manually set the XO point to match the subs XO point.

    while I agree 80hz is a good place to start, I am curious out of the specs you mentioned, what (other than maybe frequency response) brought you to that conclusion?

    I am thinking it is either the ring radiator tweeter, or the real wood veneer that drove him to the 80hz XO point:D
    Sorry I could not resist:p

    I have mine set to large, but mostly because I'm using Y cables to send signal to 2 mid woofer/subs, essentially running them and the LSi's as a large full-range set.

    I did this because, a.) I had the subs laying around, and b.) there is some mid-bass that gets lost when pairing the 9's with only a sub. It sounds fantastic.

    My processor will only allow my woofer X-over go to 99hz and i set the tweeter at 10khz. I left the mid at 1.0 khz. is this right or should I set the tweeter back down to around 2.7khz? but now these things are set back to small and they are flat out a different speaker.

    I don't know your processor, but unless you are bi-amping the speakers, messing with tweeter/mid crossover points without bypassing the factory crossovers is a futile effort.
    I agree with the 80 hz sub setting and small setting for your speakers. They simply can't handle the huge rush of effects sounds like crashes and blasts.

    I have the sub set at 80htz, but i was talking about the eq setting in my receiver that I'm using for a pre amp. I have settings for the L/R mains, center, L/R surrounds and rear L/R surrounds. I can set each speaker separately. that is what I was asking help on guys. sorry if I didn't speak clearly. on the Bass,Mid and tweeter frequency settings along with gains.
    So now with that said, where should I baseline my settings? I don't have a RTA so I just need a rule of thumb.
