the filters are applied to input channels (e.g. LFE) not output channels (e.g. subwoofer). The JRiver sub channel simply refers to channel 4 which means the LFE input channel if the PEQ block is before bass management and the subwoofer output channel if the PEQ block is after bass management. This means you need to place a PEQ block before bass management and apply these filters there.

The filters are for each channel individually, LFE means LFE channel before adding any rerouted bass from other channels.

So, for JRiver you should implement filters for each of the LCR+surround+LFE channels according to the description given for the film.

 

When LFE and bass from LCR+surround is routed to the sub output, you can apply filters to the sub output if you don't have access to the individual signals.

It is not the same, but should give good results in many cases.

Use filters specified for LFE channel.

A good bass system has a dsp able to do this filtering.

 

The multiple filters with smaller gain vs one filter with huge gain is to avoid too much overshoot due to the q, the response is not the same.

Thank you for the replies, sounds good. I watched a few movies with these settings...good stuff. 

This is a great thread, thank you for posting. A couple quick questions...

1. Applying these filters in JRiver: the LCR and back/surround filters are pretty straight forward, but should the "Sub" channel be used to apply the filters labeled for "LFE" in this thread? I ask because I'm not sure if the LFE filters mentioned here are meant for the LFE channel only, or actually meant for the sub channel (where I send all <80Hz frequencies from all speakers too)

2. Why are there sometimes multiple gain filters? Star Wars for example...2 x +6db and a +3db filter on the LFE instead of 1 x +15db filter. Do DSP's/JRiver not like filters applied over 6db?

3. Formal request for some BEQ on Star Trek Beyond would be GREAT, if possible!

Thank you
