Dual Sub EQ With MiniDSP

I posted the same question in Subwoofers section of this forum, but haven't had any luck. Don't know how to move it here, so, posting again.

I am using miniDSP unbalanced Rev B (0.9V I/O) with 2Way Advanced plugin. There is a single LFE/Bass input into miniDSP and 2 outputs going to 2 subs (1 nearfield and the other up front in the left corner)

Where do you guys apply the combined EQ in miniDSP for dual subs? I am having a hard time wrapping my head around Austin Jerry's Guide on the same subject (Page 36). See the attached image.

According to the document, PEQ is applied before the two subs are time aligned in miniDSP. If we follow that, the combined response will not follow the applied EQ response curve coz the delay setting comes at the end of signal processing.

We are, in fact, EQing multiple subs when their combined response is is not time aligned. Time alignment comes at the end of signal processing.

Am I missing something or what? Help needed, pls.

You're just thinking too much.

The time-alignment is in effect regardless of whether or not you have any EQ filters is place. Measure your response, time-align the subs, apply EQ (on either the input or duplicated on both outputs), run room correction (optional). Done.


You would probably get better response if you had posted this in the REW thread or the MiniDSP thread.

Your picture shows the 1st parametric EQ is on input 1, so that will EQ both subs. On the right side you can individually EQ output channels, which you can use to individually EQ each sub, in addition to the combined EQ or you could copy over the settings from 1 output channel to another and double your combined filters from 5 to 10.
