Hello all. I just got my Emp Tek E5Ti tower speakers. Well, I got them over a week ago, but my wife and I were out of town. Anyway, ran Audyssey and it predictably set the fronts to full band. I set my center to 80Hz, my surrounds to 90 Hz, and my sub to 100Hz. Then I noticed a feature of Double Bass. This is the explanation according to Onkyo:
"With the Double Bass function, you can boost bass output by feeding bass sounds from the front left and right channels to the subwoofer... Double Bass function on. Bass from the front left and right channels is also fed to the subwoofer (default)." So if I use this when my fronts are at full band, anything bellow 100Hz for the fronts will ALSO be sent to the sub as well, correct? I just want to make sure that I read that right. I would love to use the full band of my new fronts but keep the support of the sub. Any reason why I should keep this off and turn my fronts down to 80Hz? Btw, I am listening to music with the E5Tis and I am REALLY enjoying them. Very nice sound. |

As far as Onkyo's double bass feature goes, most HT experts don't recommend turning on that feature which is found on many AVRs going by different names. Just take their advice and avoid it. It can actually decrease bass performance. Place your towers at a location where they can give the best imaging, smoothest frequency response above 80 Hz, and best sound dispersion. Place your sub where it is more capable of producing the smoothest bass response. Then you're all set for the best HT experience you can get. I suggest that you read this bass management guide. Also read small vs large speaker setting. |

Thanks for the response. I have read the posts you linked. I understand that on regular cross over, setting the fronts to full band prevents any low Hz in the fronts from going to the sub. But I this is NOT the same thing. According to the description of "double bass" low end info will be sent to BOTH tower and sub.
Here is my thinking: let us say that a range of sounds from 120Hz to 20Hz is sent to the front right speaker. If I set the speaker to full band (sub cross over set at 100Hz), 120Hz to 20hz will be sent to speaker and 100Hz to 20Hz will be sent to sub. Now I know my towers cannot handle all the way down to 20Hz. According to Emptek my towers go to 50Hz. I know this may not be 100% accurate, but let us use this for now. So as I understand it, of the 120Hz to 20Hz sent to the tower, only 120Hz to 50Hz will be played. I don't see how this is a bad thing? No holes unlike setting the speaker to full band without double bass, since the sub still plays the 20Hz to 100Hz info. Am I missing something? derzauberer, you mentioned that HT experts recommend against the Double Bass. Any links? I am curious how it decreases bass performance. Ironically it is often argued that 2 subs are better than one. So if a 60Hz sound came through the tower channel, having BOTH tower and sub play the sound would be a good thing right? Again, am I missing something? |

"Double Bass" is only there to screw things up, just don't ever use it.
