Subwoofer connection

Spiderwoman

Hello to all big bros and sis,

My home theater system has three subwoofers, 1st sub is situated next to the left front channel facing to the king seat, 2nd subwoofer is diagonally facing the 1st subwoofer approximately 20' away, the 3rd sub is along the left side wall facing the side of the king seat 5' away. All subwoofers have been calibrated using REW and Dayton Audio UMM-6 USB mic. My question is my Marantz AV8805 pre amp processor only has two subwoofers in the manual or audyssey settings, how do I calibrate the 3rd sub in this case? Please advise...

A
1. use Y subwoofer cable to correct 1st and 3rd or 2nd and  3rd subwoofer

2. add an external subwoofer eq (i.e. anti-mode or  minidsp) to 3rd subwoofer

3. make stand alone calibration on 3rd subwoofer via anti mode or minidsp

4. use Marantz auto eq for auto-calibration

B
1. use one subwoofer cable to correct mini dsp

2. use mini dsp connect 3 subwoofers

3. use minidsp to calibrate 3 subwoofers

4. use Marantz auto eq for auto-calibration

Which model from minidsp? if it is possible please give me some coaching how to connect it to my 3rd sub and Marantz AV8805. I am new to anti mode brand, any idea which model from them as well. Thanks...

Thank you for your suggestion and it is a great help from the you tube video. However, I bought the miniDSP 4x2 HD with the IR remote and waiting for their arrival. I will keep you posted how it goes. Thanks again...
