## Questions & Answers

**Q: hey there i have a small room well this fill my room with a lot of bass??**
A: Yes I have this in my living room 20x20 and this subwoofer sounds superb a little boomy but we'll worth the money

**Q: Is the amp only rated to 150rms or is that the peak?**
A: The amp is rated at 150 watts RMS power.  This is good.

**Q: No lfe feature, right ? meaning that needs yes or yes both cables, r&l. is not working with the right input hook it to my avr lfe pre out ....**
A: You need to have a  subwoofer cable that has Y connection (both male) at one end and single male connection at the other end.  Insert the single male connection on you preamp output on your AVR and the Y connection (red and white) on FF10. Mediabridge sells subwoofer cables that are very good.

**Q: I was wondering if it is deep bass?**
A: This subwoofer produces bass so deep you need to set its frequency dial to 80hz and above just to hear it. Most other brands of similar size suffer from the dreaded thud sound, this does not dissapoint.
