Right we are "limited" to 4th order Linkwitz -Riley, which surely is a limitation, but it's just good enough for many situations.
Being able to set the crossover frequency, the filter order and the filter characteristic independently for the high pass and the low pass section would be great for us hard core tinkerers (and might steal some miniDSP revenue
). I really wouldn't mind to see this in a new "Advanced Subwoofer Settings" section. But it's not easier to set up for the beginner.
@khuntim, that means you don't have direct control over the filter steepness. It's just that combining the WiiM's low pass filter and any low pass filtering performed by the sub will inevitably result in a different steepness. You want to get the sub's filtering out of the way as much as possible.
Some subs have an LFE input (no filtering), which is independent from the RCA inputs. Some use one of the (usually) two RCA inputs as the LFE input and provide an additional switch. On some subwoofers the low pass frequency selection knob has a dedicated LFE or HT setting. Some subs just label one input as LFE but it's just a regular filtered input and the best you can do is tuning in the highest possible frequency. Go figure.

The UMIK-1 is seen from the USB-C on my laptop, then need to connect to the Ultra also I guess. no optical on laptop, Bluetooth of course. I did look at some tutorials on REW, going to take some time on this, lol
Right now the Ultra is in listening position ear height. with phase switch 0° or 180° getting different latency (Optical). do I need to test latency after changing crossover?
today I was just going to spend some time listening with RoomFit and EQ off, trying some different crossover points. Just redo the latency when changing to USB.
0°
180°
I changed to 70hz crossover and that sounds better, tried 100hz and not so much.
but the automatic setting of the delay is opposite from what I was using. 4ms with sub at 0° and 8ms at 180°
I had the speakers delayed by 11ms, using automatic sets the opposite value (sub delay)
right now at 70hz and 0°/4ms sub delay the sub sounds more powerful but integrates well. this is RoomFit and EQ off.
