What should i set the cut off frequency dial on the back of my sub ?

Running all my speakers to small with 80 crossover from the avr for all the speakers. At the moment the cut-off frequency on the back of the sub is all the way up.

Thanks !

That is the usually recommended setting, the one that causes no or a minimal high frequency cutoff. This puts the AVR and the recordings LFE channel in control of your system, which is generally the right thing to do.

It depends on what your front speakers are capable of, and what setup capabilities your receiver has.

If they have frequency response down to 50 hz, for example, you don't want an excessive overlap between the front speakers and sub, so the sub should be set to cut off above 60 Hz or so.

On the other hand, if you have tiny front speakers that only go down to 100 Hz, then the subwoofer needs to operate up to that frequency.

Some receivers allow you to set the rolloff individually for each speaker and some will set them all the same, so it depends on the functionality of the receiver setup menu.

My fronts are jamo s608 and ive set them to small with 80hz crossover so the sub handles from 80hz and down. Right ?

All good advice.

If you don't possess measuring capability, play some music with vocals, and with the help of a second person adjust the setting so it's doesn't un-naturally color the vocals,.. yet it retains the extra weight and warmth that the sub is tasked with.

Experiment, it shouldn't draw attention to itself, instead it should add seemlessly to the mains.

It is. All bass is kinda punchy and smooth but.not that strong. I gues because its a small 8" sub ( jamo sub 250) and the dial on the back is set to 9 to 10 o'clock so it stays smooth and does not rumble.
