Is my home theater ok

What do you all think of this im just wondering?

onkyo 604

HD-DVD A1

Blu-ray Br-p1400

Klipsch

one KSW-12

two FS-1

one SC-1

four SS-1

50in Toshiba 720P Dlp

THX wire on all the speakers

Is this an ok setup Im thinking of puting a onkyo 705 for the reciver so I can get DTS maser as of now my blu-ray player decodes all the other soud formats does any one know if thies speakers can handle the 80 hz crose over that thx uses?

The THX recommended crossover of 80Hz only affects your LFE (.1) channel. Few LFE recordings contain frequencies above 80Hz anyway, so the recommendation is based on reducing hum on that channel. I have mine crossed over at 120Hz, and it's totally silent and free of higher level distortion, so you may want to experiment. THX isn't everything, so don't be afraid to play around and find what works best for your mix of equipment.

Edit: I should add that my system is a lot different than yours. My Paradigm PS-1200 is a bit "wierd" and has an adjustable crossover of 50 to 150Hz with a response up to 150Hz as well, so perhaps 80Hz on both your receiver and your sub would be your best option.

You may have some issues hitting everything with the FS-1's. If you were to get the FS-2's that's a little different story. Generally the Klispch Synergy line-up is pretty solid. My first surrounds were the SS-1's I just sold my SC-1 on E-Bay like three days ago. I replaced everything with RF-25's, RC-25, and RS-25's. I got a smoking price from a local dealer. I still have my KSW-12. That sub rocks!!! I have it set to around 60 Hz. It just handles the really low stuff. I have my Onkyo set to 120Hz. I have the gain from the amp set at 6 or 7, not quite sure. I have the volume on the subs set at 4 or so. With more gain to the mix, and less volume, you obtain twice all of the sound that you would get out of a more expensive sub. You also really acheive those earth shattering explosions, and effects. Keep in mind, I do have three subs, so they are all tuned differently. One at 60hz volume level 4, One at 100Hz, volume level 4.5, and One at 130Hz volume level 4. I covered all the basis!!!

More Signal, Less Volume, doubles your results!!!

Holy Crap!

I had no idea you were so into audio. Your wife must be much more understanding than mine. Mine complains that the entire house shakes and disturbs her when she's upstairs 2 floors away from my HT room! And that's with my single lil' 12" Paradigm. Granted our house is a pretty old century home, and it's like the entire house was made to increase the reverberation of low frequency, like a big speaker box containing a sub.

Edit: BTW, you're right about less volume - more signal. I've been to a friend's house before who proudly demonstrated their new 5.1 setup with sub. And the darn thing was literally putting out square wave distortion and booming like a bad storm. He thought it sounded good. I didn't say anything.... but I bet you knew what I was thinking!

I have an Onkyo 705 and don't use the THX setup. I do use 80 Hz as the crossover point, though, and the subwoofer crossed over at 80 Hz. I use my own sound meter to measure audio output from the speakers rather than rely on the Onkyo's own mike and calibration system. But I'm old fashioned and like doing things my own way.

Incidentally and off the point, but echoing what Skyhawk said, if you have a receiver set to cross over bass frequencies at, say, 120 Hz and your subwoofer set to cross over at 80 Hz, it means in theory that your subwoofer is receiving audio signals from 120 Hz on down (but reproducing only that part of them from 80 Hz down), and your main speakers are receiving audio signals from 120 Hz on up. Unfortunately, this means that you are inevitably going to be missing the frequencies between 80 Hz and 120 Hz, which aren't being reproduced by any of the speakers. (In actuality, crossover points are approximate, and a good deal of information is still being transmitted above and below these crossover points, but that's beside the point.) The result, if you were to measure the frequency output between 80-120 Hz would probably show them too low relative to the other frequencies in the spectrum, a dip in the frequency graph. (Some people actually like a dip around this point, by the way, because it gives the appearance of greater depth to the sound field. But, understand, it is artificial and not generally recommended.)

So, in practice you should set the receiver's crossover point and the subwoofer's crossover point to the same frequency to avoid missing anything.

As far as whether your speakers can handle an 80 Hz crossover point, I'm not sure what you mean. If you have a subwoofer, surely it can handle frequencies below that point, and surely your main speakers can handle frequencies above that point. So, yeah, 80 Hz is great.

geeks

well the sub crossover is all the way up and the reviver is set to 80 hz for the sub the power is on 8

the center is set to crossover at 150 hz

the front left and right are set to full ranger

the sround left and right are set to 80hz

and the rear sround are set to 100hz

this is what the auto setup gave me

It sound preaty even like this if I take the front off of full range then it cuts out some of the bass

thought even if Put them on a cut off of 40hz I think it is something to do with double bass

any way thanks for all the help

Yup, and most extremely important for non 5.1 sources, like with Dolby Pro Logic II set on. Although I have my fronts set to "large" (and they are large) for that mode, I'd be missing a lot with the 80Hz crossover and 120Hz on the receiver for sure.

You don't get any hum or other LFE artifacts with your sub crossed up much higher than your receiver? There is really no need to set the sub higher BTW. (IMO)

ok I'll set the sub to cut off at 80hz too allthought I dont think I get anything extra With the cut off all the way up on the sub and the reciver on 80hz I have it ran on a monster THX sub cable I think it makes a differents vs the old non thx one I use to use too
