    Hi Koos

    When you connect a subwoofer to your system, it is a universal volume output. You cannot adjust volume at certain levels of the frequency curve and not at others. This is not a Bluesound limitation.

    What you can do is in the BluOS App, with your sub-woofer enabled, you have a sub-woofer volume trim to increase or decrease sub-volume by -6db either way.

    Set your Subwoofer volume trim to -6 dB then set your sub-woofer volume to the desired volume using the sub-woofer documentation when you are 'quiet' listening.

    When the time comes and you need that sub-woofer oomph... open the BluOS App and increase the sub-woofer trim. This should give you up to an extra 12 dB of "boots and pants" when you need it.

    Hi Yannick

    The SOUNDBAR does not have a separate volume setting, only a sub-woofer trim. If you have the PULSE SUB+ that's a slightly different story though. The SUB+ includes a 10 db trim swing as oppose to conventional wired subs of only 6 db

    Hello Tony,

    Thank you for your response, but I don't think you understand the question. Just for your information, I know the difference between Eq (individual frequency level) and volume (overall sound level).So, I think the sub-woofer trim option you're referring to is just an eq (with a broad bandwith/Q) and has nothing to do with overall sub output from the physical sub output connection? And therefore does exactly what you mention is impossible ("You cannot adjust volume at certain levels of the frequency curve and not at others")? And for your information, I go for a full realistic frequency representation in a stereo setting with added sub for the low frequencies. Assuming you're talking about the crossover function with sub activated? Cant find any sub trim anywhere, just high and low eq-sliders?? Now, my personal situation is having 2 passive monitor audio gold series speakers on my desk an an active monitor audio sub (with active volume control and filtering) underneath the desk. Sub woofer is connected to the sub out (subwoofer function turned of, cause I don't like to listen to the desk speakers without al the lower frequencies filtered out, and they will only be there with the sub on). Because the sub woofer has an auto-standby function, it will turn of below a certain input volume. Right now, the output volume of your sub out (no matter what I try) is so low, that the sub will only work at (for almost every listening situation) too high levels of overall audio. So I really don't care about the eq extras there are in Bluos right now, but would just like to adjust the sub-output volume (like a sub group volume, aux volume, whatever, as I'm used to doing with al most every hifi system I had before this.) To me its unexplainable that you have amplified speaker outputs with volume control and a subwoofer out with line output and now way of having any control over it besides (for me) useless eq? On other systems I even just used the headphone outs, if they had separate volume control. Again, can't understand a system like your doesn't have at least one volume controllable line output, not even a +4dBv/-10dBv option? But unfortunately this question has been going around the forum for more then 4 years and no steps were taken yet, so my guess is its a hardware limitation you can't solve with a software update? Right now I'm at the point of getting rid of my powernode2 at my work desk for being a below par audio experience, which would make me get rid of my living room system (powernode 2i) also, cause there's no use for a dedicated expensive bluesound system anymore than and I'm better of with just streaming through my affordable Wiim nodes to better hifi amps (with controllable sub outs.....)

    Good evening Yannick, but the problem is, I understand that the subtrim and the 12 db sweep is an eq boost/cut of the low frequenties and not directly a volume/more output from sub-out setting. Or, hopefully, I'm wrong. But in my experience it deliveres more low frequenties, not directly more output to trigger my/your sub into getting out of stand-by (as having treid that as a work around). The sub output increase (which is pretty normal on other systems as the Wiim amp) is what I'm asking for....Just a volume control for the subwoofer (hardware) output. As I understand the bluesound sollution is not that way, because its eq, not overall volume.....

    It's closer to gain than volume. It's not EQ.

    @Tony W.   

    I just bougth a powernode and a Sonos amp gen 3.  to compare and return the one i don't like. 

    and it's NOT a problem for sonos to control the signal to the sub.  so i can turn off the sub on the sonos app!  and i can adjust the signal, so i can adjust how loud my sub is playing.  So it's not correct this is not a bluesound limitation.. 

    no doubt the powernode, has the best sound compared to the sonos.. but it's such a HUGE disadvantage i can't control the sub on the bluos app. 

     Is that "hard wired" in the hardware of it? (should i return the powernote and wait for a prober one to come to market?)  that you can't control the signal.

    Or will you be able to build a better app version(that will also work on N330) once it comes.  So i can keep the powernode and wait for the developers to create a prober subwoofer control?
