REL High-level connection.

[audio_engr]

I´m testing a REL sub in my system for the first time, and i know there are a few steps to do for a proper connection and a Devialet setup in order to achive the best performance from both.

I´m a bit far from that procedure.
If anyone knows how to do it or a link with the explanation, i´ll be very gratefull.

Cheers.

Red wire = Right Channel POSITIVE Binding post of 220-Pro
Yellow wire = Left Channel POSITIVE Binding post of 220-Pro
Black wire = GND post (used for Phono Turntable)

That's how I've done for my G1-MKIIs & its flawless. No hum whatsoever.

Which REL model are you testing with your SF Guarneri ?

The -3dB point of my B&W 802D3 are 17Hz but using my ears and also a SPL meter having (A & C weighings), I've set mine at 33Hz for my room. If I go 34 or 35Hz, it starts to color the midrange. If I go 31 or 32, the midbass suffers. 

I have to agree 100% with @David A about the fact that the biggest mistake people make is setting the crossover too high and the gain too low. 

Please keep in mind that the modern filters that REL uses these days are 8 millisec for Ref series #25 & G1-MKII; 4 millisec for s-series & T-series hence the subs behave differently. 

You should be looking at s-series S/510 or S/812 for your system, if not G1-MKII.
