Kain Posted August 27, 2009 Share Posted August 27, 2009 For movies, do you run your subwoofer cold, flat, or hot? If you run cold or hot, please state how cold or how hot. I personally am running my subwoofer flat according to my digital RadioShack SPL meter. I am not sure if you are suppose to add 3 dB to the reading on the meter or not so I could be 3 dB hot or flat right now because the meter states 75 dB for the subwoofer on The 5.1 Audio Toolkit DVD when at reference level. However, I am thinking of boosting the subwoofer for movies by 4 dB for that extra kick. Quote Link to comment Share on other sites More sharing options...
hometheatergeek Posted August 27, 2009 Share Posted August 27, 2009 Hi Kain, I run all 4 subs, the 2 velos and the 2 HSU ULS-15 slightly warm I guess . 80db for everything. I find it is easier to read the meter this way. So zero master volume on the Yamaha would be 80db.[] Quote Link to comment Share on other sites More sharing options...
Kain Posted August 27, 2009 Author Share Posted August 27, 2009 80 dB for each one separately or 80 dB combined output for all four subwoofers? Secondly, which SPL meter are you using? If it's RadioShack, is the 80 dB the corrected measurement or simply what the meter is saying? Quote Link to comment Share on other sites More sharing options...
Mr. RF62 Posted August 27, 2009 Share Posted August 27, 2009 I run two subwoofers in my setup. One I have crossed at 80Hz with the receiver and run it about 75db. Then the second one I have behind my couch for impact and have it crossed at 40Hz and run it about 80db. Quote Link to comment Share on other sites More sharing options...
hometheatergeek Posted August 27, 2009 Share Posted August 27, 2009 I first gain matched one sub at a time to 80db then level match all four in the AVR to 80db. Which was only one notch on the plus side of zero on the subwoofer channel. I use the older analog meter and I just use 80db because it is easier to read the meter and focus on the zero which is straight up and down then trying to read +5 when the meter is set to 70db.

CECAA850 Posted August 27, 2009 Share Posted August 27, 2009 I run mine about 4dB hot. Perfectly flat just doesn't cut it for me. More than 6dB hot overemphasizes the bass too much IMHO. Carl Quote Link to comment Share on other sites More sharing options...
sunburnwilly Posted August 28, 2009 Share Posted August 28, 2009 Flat , it blends better with the Belles at normal levels . If I'm running the Belles hot I run the sub cold because it will bottom out trying to keep up with the Belles . Quote Link to comment Share on other sites More sharing options...
RockOn4Klipsch Posted August 28, 2009 Share Posted August 28, 2009 Right now and usually I run everything hot at 80 dB. My sub is flat at 80dB with everything else with the exception of 2 channel listening which the sub is running hot 3 dB to keep up with the HF section of the RF 7's. I run everything pretty flat because we watch most of our movies at or near reference level, if I ran the PB13U hot I might risk damaging the foundation of my house.
