The MB-4 can not be used as a replacement for the B1. The impedance and EQ do not match particularly well and in general we recommend using B1s.

If you still want to use the MB-4 you would have to use an external power amp. Connect the Bass Line Out of the power stand to the input of the external power amp (that feeds the MB-4). In this case you should not connect any B1s to Amp 3 out of the power stand.

Q: Can I use the PackLite® power amplifier Model A1 to power the Panaray® MB4 Modular Bass Loudspeaker?

A: the Output specifications for the PackLite® power amplifier Model A1 are similar to the Amp 3 (Bass Out) of the PS1 Powerstand (250 watts into 4 Ohms).

I would NOT recommend connecting an MB4. Its impedance doesn’t match the power stand particularly well (although you can safely hook up 2 MB4) and the bass output you may get is probably similar to that of a single B1, which is about half the weight and half the size. As Ken & Thomas have already pointed the power stand can sense the presence of a B1 and adjust the EQ accordingly. That is not the case for the MB4 so the overall system voicing will be somewhat off.
