Ebag4 or Danny,
I am thinking of using 2*M130 in MTM configuration, are you using the 16ohm version or the 8ohm version.
The latter gives a slight better effciency about 96db which is compatible with the neo ribbon tweeter, hence no need for resistive attenuation and possibly easier x-over design between neo and M130.
I have 2*M130(8 ohm version) already, buying additional 2 units then I am ready to rock.
