Passive Sub Woofer connections ??


My 3rd system has a passive sub.

The NHT sub has a pair of right/left speaker terminals)

No provission for coax.


Should I go 4-wires from my amp to my sub, then 4-wires from the sub to the speakers.


4-direct wires from my amp to my apeakers, and 4-direct wires from my amp to my sub(sharing the speaker terminals on my amp with both the speakers and sub)

In case A, there's the possibility of a HP filter being inserted to remove the low bass from the main speakers. In case B, that possibility doesn't exist. The user's manual should say so.

If a high pass filter can be employed you might want to consider it if your main speakers are fairly small.
Thank you all
