I’m curious if any of you have hit latency issues with SVS subwoofers with the DSP. I use a MiniDSP preamp where I send stereo outputs to the amp and a separate output to the powered sub, and I find I have to delay the mains by 12ms to get them to line up. I found a number of 6ms on the SVS website, but 12ms seems to be what works in my room. I had originally tried 6ms and it felt like the sub was barely on since it was playing late, which is rough for e.g. a bass drum.
I don’t think the Luxman that OP mentioned would have this feature, so I wonder if DSP would be a bad idea here compared to an analog sub with no latency.
