Do I need a sub?

Would I benefit from even a small sub?

Energy rc-70s’
dual 6” woofs, bass is there, but would a sub remove the lowest freq, and give the small drivers a break, and sound better?

would it help,? I play loud once in a while, would the low freq removed from the main tower drivers make a better sound, I don’t think I would need much more than a 10 or 12” sub. 

Powered or unpowered?

thoughts?
thanks

Found a great price, so I bought 4 of them.
one for my cousin.

 
 If I hook up via speaker wire, doesn’t this push the low freq from the main towers to the sub?
or still full range for towers?

If you don’t use a high pass filter the towers are going to run full range. If you want to add a high pass filter you can add this! I used it when I had a sub with no  high pass filter with great results!

Just checked the website, the speaker terminal hookup “is” a high pass filter.

 Monoblocks to speaker terminals on back of sub,......then speaker terminals to tower speakers.  This is how I will hook up.

 Only problem is the long speaker cable runs, 

thanks for all your help.

They label it as high level input?
