I came across this crossover image.
I believe R6, C5 and L6 are to reduce bass if the speaker is used in a corner. If the speaker is used elsewhere ie out from back wall and side wall could all these components be omitted.

If you give the values we can work out what frequency they are tuned to.
Reducing the bass by shunting only works if the series coil has a relevant resistance/reactance in the respective frequency band and I highly doubt that.
(I should add that the RCL element is very likely tuned much higher than "bass" and thus works - as White Dragon wrote)

It is supposed to an impedance flattening circuit.
In the write up about it it says that if you want bass disconnect R6 from C5.
What I am wondering is that being the case can you leave R6, C5 and L6 out altogether.

Most likely notch to tame some HF peak.
Impedance flattening is usually not necessary with 2nd order filter.

The more information you provide, the more chance there is of getting definitive answers. What are the speakers? A commercial speaker you're renovating? A kit you're building? What are the drivers? Photos?

I forgot to say in my first post that the circuit shown is for the bass driver.
So going back to my original question can the 3 components be left out if reduction in bass output is not required or should R6 simply be disconnected from C5

Thanks, but that was clear due to the low pass filter so we're no further ahead.
Do you have a photo showing the size of the components?
Sorry no other info. available.
As I said earlier it is stated to reduce bass if used in corners etc

Yes, you did. I was going to pursue that line but got distracted after I didn't get the values.
Why don't you try it? There should be no harm. Could you measure the result?

It's a kit, I can buy the schematic with values and thought if I don't need those parts it would pay for the schematic.
So, there's a write up, I assume by whoever designed the filter, and he/she is the one claiming that. If that's the case, then yes, disconnecting R6 from C5 takes R6, C5 and L6 out of the circuit, so yes, you can omit those components altogether.
