I didn't realise I could have just split the output (would have to check the load of both inputs to make sure, I just read). But balanced for the long wire-run to the second room is much preferable, while RCA for the subwoofer gives me more sub options - so I think the track I'm on with my DAC is ok. I'm not picky about the second room... As long as the main living room with sub is fairly accurate I don't mind if the second room is a bit whacky and there won't be a sub out there. Synchronised streamers - never heard of that oneYou can use a splitter cable and use two different calibration presents, one for each room. The MiniDSP offers room correction but each preset is for one set of speakers in one room. The way to do multiroom is to use a set of synchronized streamers of your choice and separate room correction devices.
Awesome information, thanks! The green line looks like a match. I will try those settings on the SB-1000 Pro (hopefully in a couple of weeks). Will have to read up about polarity. Maybe with the SB-1000 Pro's PEQ and the Genelec's other DIP switches I can flatten it somehow... sounds like room effects might overwhelm the 3dB wave anyway. Good to have a starting point though.I've attempted to model the Genelec 8030 low-frequency response using VituixCAD. To get the response corresponding as closely as possible to that with the "Bass Roll-Off" option activated, I needed to use a 2nd-order high-pass filter with Q=0.53 and set to a frequency of 53Hz. The match then seemed quite reasonable.
I've also added a model of the SVS SB-1000 Pro subwoofer to the simulations. To get a reasonable blending with the "Bass Roll-Off" option active on the Genelec 8030, I needed to use a 3rd-order (18dB/octave) Butterworth low-pass filter set to 70Hz on the subwoofer. The polarity of the subwoofer needed to be negative. The resulting frequency response functions are shown below.
Note that the filtering is far from optimal, as there is a very broad region of overlap between the subwoofer and the main speaker, and the individual responses are not very complementary (in the filter sense of the word). The reason for that is related to the fact that we are trying to use the "Bass Roll-Off" option as a pseudo-high-pass filter for bass management purposes, and its shape was not designed for that task.
