I see there is a 3.5mm sub out on back of SB 700. Am I able to use shielded cable to use an other than Bose sub? I understand Bose would like us to purchase one of theirs however I have a couple extra subs setting around and want to look at all options. Also if I use the 3.5mm out does that eliminate the wireless sub from working? And finally which is better sound 3.5mm or wireless? I have no issues with a wired sub).
We do not recommend that you connect a non-Bose Bass Module to your soundbar 700. If you connect a different Bass Module to your soundbar, not only can we not guarantee this will work but this could cause damage to your soundbar.
Please let us know if you have any further questions.
