A/V receiver / subwoofer crossover question

[ThA tRiXtA]

<font color='#000000'>I just purchased the Energy E:XL S12 subwoofer tonight, to go along &nbsp;with my Onkyo TX-SR701, and I have run into a little issue...

The crossover on the sub is adjustable between 50 - 100 hZ, whilst the low frequency cut off of the receiver is 80 hZ.

Unfortunately, I &nbsp;cannot defeat the Onkyo receiver crossover.

However, if I use the other low level RCA input on the sub to defeat the crossover on the sub, I lose all controls on the sub including phase, gain, volume and bass EQ.

I wish not to lose the functionality of those 4 controls, as they quite help to sculpt the sound of the sub.

I read some articles on the audioholics site here stating that if you have two non defeatable crossovers, to set the sub crossover as high as it could go and adjust the receiver crossover to the desired setting.

My question being, which is usually better, the receiver crossover or the sub crossover, and why?

Since the receiver crossover is not defeatble, should I switch the input on the sub to eliminate the sub crossover, and lose functionality and all bass controls, or do I face a quality of sound loss having the two crossovers interact with eachother?

Is there any quality issues or anything else degrading to the system by using this method?

Thanks to all

&nbsp;I've been playing around with the same issue for a while. What I've ended up doing is using the subs' xover &amp; setting it to 60 HZ &amp; my receivers LFE to &quot;both&quot;. My mains(Bostons) dont do much below that freq. so it works fairly well. For movies I set it to &quot;SWFR&quot; &amp; let the sub handle the load. Also move the input on the sub to &quot;bypass&quot;. This allows the receiver to do it's &quot;Dolby&quot; magic w/o my interference.
&nbsp;This is something you can(&amp; should) play around with to suit yourself. Will take a while, but in time you&quot;ll find a combo that fits. Don't be afraid to try everything.What sounds best might be an odd combo.</font>

<font color='#000000'>Ok I will play around with it and see what happens...

It's just that I take a hit either way, either I pass through two crossovers, or I pass through one and have no volume, gain, phase or any control whatsoever.
