<font color='#000000'>Greetings,
I will be picking up this previously enjoyed unit to-day and it will be married to an upgraded Denon 5800.
The SUB 2 goes to 21hz +-3 with a 500w Sunfire amp and 2 10" drivers and a separate controle box.
I have 3 questions.
1. In the speaker setup of the Denon the onscreen display asks "Do you have a THX ULTRA2 cetified sub or one that goes to 20hz". What should I answer here?
2. Since the Denon seems to want control should I still use the control box?
3. Since my relatively small room 15'd X 10-12'w X 8'd will not need huge volume settings, does that help or hinder the bottom end spec or does volume have nothing todo with it?
Thanks,
Peter m.</font>
