    Beolab 5 bass issues

    Hello. Have some "problem" with the Beolab 5's. I think the bass isn't as its should be, specially on low volume. When playing loud it's ok. I'm using them with the Beovision 7-40, and they are correct installed and calibrated, but i don't think it's enough. Any suggestion to make the play more bass?

    Re: Beolab 5 bass issues

    If you've calibrated each of the BeoLab 5's, and done a proper set-p in the BV-7's sound menu, then I would make certain that the Loudness in on.  Other than that I'm at a bit of a loss.

    I'm not familiar with the BV7 settings, but maybe worth having a look at those to see whether the LFE signal is channeled properly. Is there an option for picking the type of speakers?

    Re: Beolab 5 bass issues

    If you previously have had another setup with a subwoofer, you need to change the surround setup from "subwoofer on" to "subwoofer off".

    I didn´t do that, and was slihtly disappointed at first. Very happy with them ever since.

    Just speculating of course...

    Re: Beolab 5 bass issues

    I have this problem, too. In fact, the BL3s feel more 'bassy'.

    However, I'm sure it's to do with my room setup. When they were first placed in the room and calibrated, the bass was far more signifcant, but then there was little else in the room.

    Since the room has been filled, then the speakers re-calibrated (I wish I hadn't bothered now!), I've noticed that the bass is almost non-existant, clearly as the calibration has resulted in the speakers thinking the room is tiny, due to the furniture and other items around the speakers.

    BL5s seem best when they do not have too much around the speakers so they can be calibrated in an almost empty room.

    Re: Beolab 5 bass issues

    No Loudness on, and haven't configured with a subwoofer, all bass through the BL5's. 

     

    Calibrated the speakers first with all furnitures on their place, but then it was no bass at all. I was removing all furniture then calibrated the speakers and got much better bass, but not nearly enough. With 1000 watt on hands pr 15" it should be much better! I know they of course get nowhere near this at low volume, but should be better than this. Have the latest software and also tried a CD/DVD player directly to the speakers without using the BV7, but its the same.

    Re: Beolab 5 bass issues

    I've just re-calibrated mine and it made no difference. Oh well. I wonder if some of it is to do with the sound source? Most modern CDs are very flat. My BL9s, connected to the TV, are awesome with movies, particularly Blu-ray movies. I can imagine the BL5s would be a step up again.

    The same CD I tested on the BL5s, played via the BV7 and BL9s, sounds flat with little bass.

    My conclusion is that our expectations are too high. We assume as we've bought top-end speakers, that they should turn our poorly engineered CDs in to a masterpiece of aural entertainment. Sadly, they don't.

    Re: Beolab 5 bass issues

    When i play very loud, the bass extension is very good, couldn't expect any more in fact, but on low volume I wish more bass. But I have a trick left, let me try...

    Re: Beolab 5 bass issues

    Excuse me for sticking my oar in, as I have absolutely no experience with Beolab 5,  but I'm sure I read somewhere that the floor can make a big difference when calibrating.
    If I remember correctly, one of our members was having trouble and it was due to his suspended (and slightly flimsy) wooden floor.
    It was corrected by building a block base under his floor that soaked up the vibrations.

    Re: Beolab 5 bass issues

    This was an Australian BeoWorlder, JandyT, who had a wooden floor that "gave" easily. Dave Moulton recommended stiffening the floor with a few supports underneath, and that recovered the bass instantly.

    But Moxxey above has a point. Most newer music has very little dynamic response, which means that the speakers don't get much to work with. Yes, there's a wall-to-wall LFE signal in the music, but bass works best when the music has changes between loud and soft.

    Another point: I thought my bass was off not that long ago, didn't really grab me. So I went through all the settings in my signal chain, including the menu settings, and discovered that someone (not me!) must have initiated a Dynamic Range Control option in my processor, which reduces the bass.
    Fixed that - and the bass I knew was back.

    But Moxxey's point is important. Not only has music gotten a suppressed dynamic range, but remasters of older recordings are also getting a reduced dynamic range, compared to the original. All because people are listening in locations with high noise floors, which requires the music to be raised above this level, thus killing dynamics.

    So - what you listen to may be just as responsible for a disappointment with the music through your system, as the system or setup itself.

    Here's the thing. If you're listening to an original mix, or a recording with a good DR, then you will very likely have to turn up the volume to get good bass, while newer releases of the same music will have been given a higher level - you don't have to touch the volume, but the dynamics aren't as good. If you want more information about this, have a look at this site: http://www.turnmeup.org/

    Here's an example. Led Zeppelin, Since I've Been Loving You.

    Three versions: 1. The original 1980 release 2. The 1994 Remaster 3. The 40-Year Audiophile SHM-CD (Which is actually not audiophile at all, it's got borderline clipping.)

    All the detail, and all the dynamics, have been preserved in the first one, while 2 and 3 show exaggerations, compression and detail being obscured - there's also evidence of quite marked use of EQ.

     

     

    Listen to this - preferably through your sound system, from the computer. In the post below, I'll explain what you heard.
    It's Genesis.

    http://home.comcast.net/~captaincasual/01_Genesis_Compare.mp3

    Here's a list showing what's happened to the dynamic range - note how releases around the 80s all had great dynamic range (it's the number marked in bold on most of the entries), and then how the dynamic range becomes smaller. DR measures the difference between the lowest and the highest sounding portions of a track. Some remasters actually have lower DR than the original releases.

    Re: Beolab 5 bass issues

    To those who listened to the Genesis sample.

    http://home.comcast.net/~captaincasual/01_Genesis_Compare.mp3

    It has three versions of a portion of the same track.

    1. The original mix.

    2. A remaster.

    3. A sound engineer's attempt to tweak the original to get a result similar to the so-called remaster.

    SO - don't think you have good bass just because the CD says Genesis, Supertramp, Donald Fagen (well, usually he has a good handle on the output, though a Gold reissue of AJA which he had no hand in, got everything wrong.)

    Here are the details as to the three tracks:

    As a recording engineer it's been incredibly frustrating for me to see how many people find the Genesis remixes not only acceptable but superior to the originals. I wondered how much manipulation it would take for me to make the original mixes sound as harsh and compressed as the remixes.

    I took the first track from ...And Then There Were Three... (original Atlantic CD) and ran it through some EQs and compressors and digital limiter while A/Bing it with the remix.

    Here are my final EQ settings:

    +15dB @ 7.5 kHz shelving
    +9.5dB @ 16 kHz
    +9dB @ 1.5 kHz
    +7.5dB @ 250 Hz
    +4dB @ 50Hz

    But it still wasn't quite harsh enough so I patched in a second EQ:

    +7.5dB @ 3 kHz
    + 10dB @ 125 Hz

    Then I hooked up my SSL compressor (the same one Nick used) and did 4dB of gain reduction @ 10:1 (the highest ratio it has). Still wasn't enough so I hooked up my Pendulum 6386 Vari-Mu compressor and did another 4dB of compression.

    Now I was beginning to hear some similarities between the two. I also ran it through a digital peak limiter taking off another 2dB and we have a match. The kick drum and vocals are louder on the remix but the rest is pretty similar.

    Here's the order of what you're listening to... Original Atlantic CD unaltered, the Remix and then the original Atlantic CD pummeled with EQ, compression and limiting.

    soundproof:

    This was an Australian BeoWorlder, JandyT, who had a wooden floor that "gave" easily. Dave Moulton recommended stiffening the floor with a few supports underneath, and that recovered the bass instantly.

    That definitely applies to my scenario - wooden floor, little support etc.

    Listening to the latest Depeche Mode 'Sounds of the Universe' CD and that's fairly well engineered - sounds little better on the BL5s than my BL3s. There's a strange 'mid range' to my BL5s lately.

    Re: Beolab 5 bass issues

    I don`t know if this helps, but I know there was a BL5 software that had calibration problems. The BL5 didn`t calibrate correctly when located on wooden floor. We have a wooden floor too, and my 5s were updated to 1.62a before installing them at my home. I have no bass problems at all.

    Re: Beolab 5 bass issues

    I know that the BL9s and the BL5s are flat in their response curve which, despite how that sounds, is a very good thing. Alot of people have trained their ears to speakers that color the music a bit to give it more "Umpf". The problem is when people hear really good studio reference monitors (as the BL5s essentially are) they sometimes don't like the sound since the BL5's don't "candy coat" the music as most speakers do. This doesn't sound like the case in this particular situation but I'd hate to hear a speaker such as the BL5 get criticized for something it is doing right. The more people understand the BL5 the better.

    Re: Beolab 5 bass issues

    Definitely not being criticised, but I/we're not going gloss over something if it's not quite working right, are we? No point just saying they are superb and 'be done with it'. Clearly my problem is now my wooden flimsy floor and increased furniture count, which means any new calibration results in far poorer bass.

    If I re-arranged the situation and/or move to a new place (new place based around the BL5s, perhaps?), then it might be a different matter.

    Re: Beolab 5 bass issues

    I hear ya. There are so many variables. I was just pointing out that in general Bl5s are probably going to start out flatter than most speakers and that, in most situations, through calibration and audio settings you can get them where you need to go. It's interesting about your floor. I've got a grand Piano that has had similar issues. The wood floor it's on not being as supported in the sub floor as well as the area around it. Similarly, it's as if it is sitting in the center of a drum which absorbs much of it's power.

    Re: Beolab 5 bass issues

    The Australian BeoWorlder had moved to a new house, and missed the crispness and report of his BL5 bass from the previous residence, and this gave him a good reference for what was missing.

    The two sub-woofers on the BL5s together move several liters of air when working at optimum (if I remember correctly, each can shift 1,8l/pulse). There's the risk that a place with soft floors or walls will be absorbing that energy, instead of reflecting it. But I agree with mhodges, people have gotten so used to hammock-shaped frequency response curves that exaggerate the lows and highs, instead of the ideal flat response, that you'll sometimes have people feeling "is that all there is?"

    I've had fun just boosting the bass when I'm asked that question - as I prefer acoustic music, I have my speakers set for a flat response, and at this, the BL5s are phenomenally realistic, from 20Hz onwards (with a respectable showing below 20Hz, actually.)

    So - when I turn up the bass to and past the WHUMP! they're used to, they can feel the whole apartment shake, and then I dial it back to where it should be.

    One of my favourite recordings is "Play Bach" with the Jacques Loussier Trio - my BeoLab 5s turn the recording into the sheer joy of following the details of the bass and drums, while Loussier teases miracles from the piano. No need to exaggerate there!

    (The latest Die Hard movie, with the scene at the end involving the fighter plane and the truck, is a good demo if you feel you're lacking bass. Make sure your expensive china is secured!)

    Re: Beolab 5 bass issues

    I saw The Dark Knight on Blu-Ray through BeoLab 5s yesterday - don't think I've ever heard so much bass from a consumer sound system! If they do lack bass, it's almost certainly to do with the room or way they're set up.

    What a coincidence! I saw the same movie last night on Blu-Ray, and you're right. Very much bass. 

    Hm, have to check out some other possibilities, go through the settings again.

    Re: Beolab 5 bass issues

    The ICE power amp do have 1000watts but how much current does it have? I have asked the audiodevolpers in Struer and no one could answer my question?

     

    That's why you most set the volume at 75 on the Bc2 or Bs5 to hear plenty of bass in the store, but our costumers don´t want to play that loud to get bass. If you increase the bass eq with +6db you only increase the midrange in the Beolab 5 not the 15" subwoofer!

    A parallel: Current is like torque in real life.

    It´s like a 240bhp Honda S2000 Type-R with no or 190Nm of torque Vs 250bhp Mustang small block V8 with 430Nm of torque. The Honda you must rev it to the red line limit to get all the power. And with the Mustang you have plenty of torque power from 1500 rpm- 6000rpm redline.

     

    I think Beolab 5 doesn't have enough current to drive and control the 15" peerless woofers in the right way. That's why it´s so little bass at lower volumes!

     

    My 3 cent..

    Re: Beolab 5 bass issues

    I disagree - I find them to simply be very linear at all volumes. Compare this to the other BeoLabs which have a significant low-end rise when at very low volumes, and you could easily think the BeoLab 5 doesn't reproduce the bass it should.

    Re: Beolab 5 bass issues

    I'm not privy to the circuit-layout on the BL5s, but would find it curious if the volume controlled the power-supply to the amps. The volume control will decide the attenuation from the amp's to the drivers, but that's something else, and quite sophisticated given the processing ciruitry in the BL5s.

    For what it's worth, I've been impressed with the presence of bass at low volumes myself, but this could of course be coloured by the kind of music I listen to, where bass reproduction rarely is the important element. (Acoustic classical and jazz, mostly.)

    Re: Beolab 5 bass issues

    Alex have you been hypnotized by your B&O dealer? I haven´t read a single post from you were you have criticized B&O?!(Besides the Beolab 2) I find it a little bit strange? Because I work full time at B&O in Stockholm, and me, my colleges and all other stores have plenty of things that we don´t like with the sound, picture and function in the product´s! This brand have often high performance and high quality, but i´ts not the best.

    B&O are not the holy grail if you think so! Come down to earth please! =)

    Re: Beolab 5 bass issues

    I don't really feel the need to criticise in any situation unless it's particularly constructive, and pretty much all the issues I would raise with B&O are things they have already highlighted themselves; what use would it be if I were to make exactly the same points?

    And no I haven't been hypnotized by my dealer - I work for them. Wink
