View Full Version : Bass management
I continually find frustration with my sub and how to manage bass on my music and films. Is it just a fact of life that you have to constantly tweak ur bass volume depending on what ur watching and listening? for example... ive found with my new setup, a Denon amp... that i didnt feel i was getting enough bass. so i turned it up on the back and also on my amp setting.. so i am watching Speed, getting enough bass thinking for the most part my sub power is fine for now... but then ill pop in Jailhouse Rock on blu-ray and go to the Jailhouse Rock scene and the bass just totally overpowers and kills the sound on it so i have to lower it considerabally on my amp vol.. is this just the way it goes with home theater setups?

.. is this just the way it goes with home theater setups?No. Once your subwoofer is properly calibrated, you shouldn't really have to change it. Of course, some soundtracks may be mastered slightly differently than others and the bass level may vary a little bit from disc to disc. And there is also personal preference.
How are your players' audio connections connected? If you are using multichannel analog connections for the BR player, you may need to calibrate it specifically using a calibration DVD as opposed to the calibration tones built into your receiver. Also, I think that even with an HDMI connnection there may be some issues with the subwoofer channel level in certain BR players.
Yes! Not all listening materials have the same reference point as they are mixed by different individuals. So, yes you will have to tweak your settings for what you are playing. How much you tweak depends on how your gear is setup and the room it is in. Is your room EQ'd and do you have bass traps, etc.? Or are you in your living room with your speakers and sub with none of the above? It all depends on how much time and $$$ you want to spend on this hobby and what you consider as good sound. The learning curve can be high and can also be very rewarding. Good luck with your gear.

LOL! ;)
hammong 07-12-08, 04:51 PM Once properly calibrated, you shouldn't need much adjustment from title to title. You receiver probably some easy way to boost/cut bass without going into the receiver configuration or getting out of your chair to adjust the sub input level. I know my Pioneer has an option to boost/cut bass and treble +/- 6dB without changing the calibration data.
It could be that your subwoofer isn't sized properly in relation to the rest of your speakers and room. E.g. If your main speakers are much more efficient, they may get louder "faster" than your subwoofer does when turning up the volume, due to a wide difference in sensitivity. An incorrect bass management setting like the wrong crossover values, or mistakenly setting your speakers to LARGE and/or the subwoofer to LFE+Speakers will make the problem worse.
An external bass management system, like a Velodyne SMS-1, or a subwoofer with digital preset controls and memory settings will make switching profiles a snap. Of course, they're not cheap. Look towards getting your bass management configuration right first.

Kylan got three different answers to his question and they are all correct. We really don't know enough about his setup.

well here's the deal... i really dont like alot of bass to be honest, esp with my music.. that being said... i felt my sub wasnt outputting like i used to have it when I had a Yamaha reciever before the Denon but it crapped out on me so i bought the Denon.. i really dont care for it to be honest... anyway its a small to med sized bedroom. Im running a PS3 to my Denon HDMI. Like i said...i was enjoying Speed and had my bass enough to where i like it.. but then as i say i go to JR and it just blows... now ill be the first to admit, when it comes to all this u guys are way over my head in knowledge. but i think its a software issue. what is strange too is this... ive got SIRIUS connected to my amp too and it plays way too bass heavy as well. so I don't know. The sub btw is about 5 yrs old perhaps. a Def Technology. also got the 5.1 sat setup from Def thats the same age as the amp.. Pro Cinema.
JBLsound4645 07-12-08, 05:20 PM I prefer more hands on route which is what I took several years ago. So far it’s worked out quite well with the ole audio mixer patched into the system. I would like to add few more DCX2496 and use it for sub bass arrays and one for surround arrays. Yes its all, good stuff.:)

If you get a chance, do some basic measurements of your room bass response with the sub. If your sub has significant peaks at 1 or 2 frequencies then some movies might not "overexcite" those frequencies but others will, giving the impression of too much boom on those movies.

An EQ might be what you need.

Yes a parametric type the Behringer BFQ2496 is good choice.
