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?

Search Swarm subwoofer, distributed bass array or DBA, and read posts on subs by millercarbon, noble100, and Audiokinesis, hallowed be thy name.
We've beaten this subject to death.  Short answer: You can have one, but you don't absolutely have to have one. Take a look at this thread:

If you feel you are missing slam, maybe look into improving the speaker placement or adding room acoustics. They may give you more for your dollar without adding a new speaker which may be hard to fit acoustically.

Large room, 16-17” vaulted ceilings.

 Left speaker (from couch) faves open hallway, staircase 
right speaker in corner,

does it matter where a small small sub goes?
I have Lansche 4.1 with two 10 inch active woofers which is supposed to go to 20hz.

But after augmenting it with two Scaena 18 inch subwoofers, it go more dynamic with stable bass foundation, wider and deeper soundstage.
