Dual mono with REL Subwoofer

[Antoine]

I’m also using a Dspeaker device to apply ‘room correction’ to the subwoofer output. In my case it’s the AntiMode 2.0 Dual Core connected to the pre-out of the Devialet and the sub then connected to the analog outputs of the AntiMode.

I agree with sam1000 it’s a very effective and easy to use ‘tool’ to flatten the response and avoid the big peaks. It won’t fill up dips due to cancellations as that is fysically impossible but it will give one more freedom in subwoofer placement e.g. in a corner or near walls.

Years ago I made a picture of a before and after, it’s here: https://devialetchat.com/Thread-Antoine-...390#pid390

But there’s many forms of DSP of course, both software or hardware based. One could also use REW like sam1000 mentioned to create convolution filters and apply these in Roon for example.
