1.How large should the speakers be to set them to "large"?

2.When i do set them to "large" the bass from LFE(.1) is also played by the "large" speakers.Also they work like sub to play other channel bass.
How do I make the sub alone play LFE and leave the fronts for it's own bass?

3.The crossover is at 150Hz.How can I change it?

Model : Sony HT-SL5.

1) opinions differ, but 98% of speakers should be set to small, even relatively bass capable tower mains. While it seems painful and counter productive to starve your main speakers of deep bass, your really better off if everything under 80 Hz comes from a point source, ideally a good sub in a corner. You protest- "my speakers are flat to 32 Hz". While that may be true, it is beside the point. The answer to the question "can my mains play deep bass" may be yes, but it is the wrong question. The correct question is "between my main speakers and my subwoofer, which one plays deep bass BETTER". Let the specialist do its job.

2)
Incorrect. The mains only get the LFE signal when subwoofer is set to "off" or "none". Setting any channel to small causes material in its channel that is below the crossover to be redirected to the sub out. Thus, if all 5 channels are set to small, then the sub will play the LFE PLUS anything from all 5 channels below the croossover. Conversely, if all speakers are set to large, then the sub will only play the LFE (and only it will play the LFE).

3) There must be a menu setting to lower it. 150Hz is too high. If you set your speakers to large though, it doesn't matter because the receiver's crossover won't be used.

I have a 5.1 test DVD.When i switch off the sub(manually, not in settings) the bass(LFE 0.1) still comes through fronts.

Also the sub still plays bass from fronts even if "large" is used.But i want to stop the fronts from overloading with LFE.

I was experimenting removing connections etc.

My reciever came with a package of satellites.I am not sure if there is a setting at all to change the crossover.Can anyone check on the model and help me.
Is the bass level knob on the sub used for that or just to adjust the level?
