700 sound bar different brand subwoofer?

Hello all, 

 

I am looking at buying a 700 sound bar to go with a new TV, and already have a nice powered subwoofer from a different audio setup. It has RCA inputs and it’s own amp. 

Can I use this subwoofer on the 700 sound bar sub out? 

Thanks for any insight. 

 

No, The SB700 only works with the BM700, BM500, AM300 bass modules either wireless or wired
