How To Blend Your Subwoofer(s) with Your Speakers

There are 3 Main things to keep into consideration to help integrate your Subwoofer(s) with your system. In this video I talk you through Subwoofer settings to help you blend your Subwoofer with or without calibration!

I calibrate my subwoofer in accordance to your suggestion and it work wonders! Music is the better way to calibrate than movies because music have this repetitive rhythm where you can easily analyze if the sub is overemphasized, thin or just right.

[@edifierbass7821]

Just keep on adjusting the until you it suite your taste, don't worry much about the freq. its already given and adjustable follow your ears and chest, the rest will follow...

[@MyFatherLoves]

This is an inherently lazy comment. Having a linear FR in both loudspeaker and subwoofer is very easily discerned once you have it dialed in vs listening to a system that isn't dialed in properly. It kinda ruins you after hearing a system that's been tuned flat. I do agree with you whole heartedly that a system is lastly eq'd to taste but if you haven't first flattened the FR through verified, manual, sweeps from a program like REW and a mic, your system will never truly disappear. Audyssey only shows a simulated averaged response. Every system's auto-eq has to be manually tweaked to be correct prior to eq-ing to taste. Even Trinnov's Optimizer.

Hey, I am running a prx918xlf powered subwoofer along with two prx812w JBL powered mains. I have the system powered with my Roland, TD 27 drum module, what I do is play along to music that I have coming through the system as well as my drums. I’m new to sound so I don’t really understand all the terminology or where I should set the EQ on the subwoofer, right now I have it 80hz I’m not sure what the term crossover means. I also have the capability to adjust volumes and tuning through my drum module. I think I have a pretty decent mix, but what you said really helped because I can’t really seem to hear the subwoofer other than my bass drum coming through so my thinking is what purpose really does the subwoofer serve any advice on tweaking and adjusting would be great thanks…. Sound is subjective and there is so many variables when it comes to different rooms and how many people are there any tips on That would be great as well. PS I am only running one sub

[@Kpaceguy]

Your subwoofer probably isn't as loud as your drums. A kick drum is no lower then 60hz abs everything else is higher so you want to set your sub crossover probably as high as you can to make sure all the drums come through

[@joevillafranca8447]

I don’t really see a setting for crossover. I’m wondering if it’s built in and the system just knows when to do it, so you’re saying higher than 80hz Like say 120hz?

[@davidj.martin948]

to blend in the subs while listening to good audio where do you turn up your subs so there to loud, on the Gain or in the Receiver and then which one do you start to lower to blend. Im thinking you turn up the Gain and then go into AVR and lower but then you undid what Audyseey set . When you run audyseey the gain is at 12 oclock on the subs, are you saying after Audyseey raise the Gain What if Audessy set your AVR to -4 on for the Subs you cant very well lower it anymore ? Thank you

I tend to leave what the receiver did alone and make sub changes on the sub itself

Movies tend to boost the LFE track by 10 dB, so I did what you did with the sub level but with the trim set to +4 for music, and then at movie time I set it to -6 to counter the 10 dB boost so it still sounds the same.

[@minos3258]

Why not just reduce the LFE by -10 or whatever Value you want? Thats why i do in my Denon and then raise my Subwoofer by +3 to +8, based on Preference. Thing is, the Audio Calibration built in bases on LFE and so all normal Content is cut off by at least 10 db...

You say you crossover your subwoofer at 50hz for seamless transition from your floor-standers which are set at 40hz.

Rather than your other speakers and sub?

Since speakers move only in 2 directions, in and out, 0 and 180 makes sense. How does everything in between work then?

[@Kpaceguy]

Its all about delay. 0 and 180 is basically exact same movement or exact opposite movement but in between 0 and 180 is kinda the same movement or kinda opposite. A variable dial controls just how opposite one sub will be from the other. Think of it as lag time. If that makes sense.

Honestly you'll be fine with either. Your decision needs to be based off the kind of performance you're looking at. If you want to match your sub with your speakers maybe stay klipsch.

If you turn it up on the gain you cant very well be sitting in your listening area and getting up each time and going over to the sub and turn it down until it blends so you must of meant in the level trim on th AVR so aren't you undoing what Audyseey set for your Sub level ?

[@Kpaceguy]

If you have an extra pair of hands you can use the subwoofer controls

[@NathanOakley1980]

Did you measure that the L&R can hit 40hz in room at the same level as they play say, 100hz? You need to figure out where they roll off in room. You cross over where they roll off in room at around 3-6db down so, if the L&R are -6db at 70hz you cross over at 70hz. Then measure with a phone app that can show you a frequency response and adjust till you get the right summing at the crossover point. The end result should be a similar level from 20-200hz when all 3 (L&R&Sub) are measured.

[@Kpaceguy]

My processor measures. It's a pretty linear response. But I ended up going with 50hz

[@recoveryone1]

Need to use a reference source, streamed music is not a reference source as most if not all is lossy format (compressed file). A good CD would be best or use SACD or muti channel music DVD/Bluray.

[@djx-factor992]

I have to agree with you here on that. Perhaps something with real instruments like a good jazz recording with an upright bass, pianos, drums, etc... would make excellent reference material. This way you can get the natural variations in tones, volumes and the like as a good point of reference for calibration purposes.

[@Test-Pilot1194]

Ladies and gentlemen, welcome to the world wide phenomenon that is, subwoofer integration. 2ways you can do this. Let audyssey choose and leave it, with minor tweaks. Or use your ears. One will take 20mins, and the other will take 20hours. I’m forever playing with mine and recently they threw another spanner at my ears when after a calibration they started performing differently. I don’t know if it was an update of what, because of all the winging over Denon exaggerating their bass. Which was a load of shit. But if they’ve changed it, it for the worse. I’d rather too much, and then tune them than have too little. Either way, I used to be able to set my subwoofer in my old marantz, at 80hz, individually, and the LFE set to 120hz. In my new Denon, I can only set the LFE....so individual Xover is either gone, or extremely well fuckin hidden. Leaves me constantly playing around to get them right. About 2weeks it’s been now. Anyway. Good video man. Keep it up.

[@Test-Pilot1194]

ksaunders359 I think. I’m just guessing, it’s been a while since I had my Marantz, but I think it was the sub to mains Xover point, in stereo modes. For surround modes there was just an LFE Xover, which should just be left at 120hz anyway. I don’t change that. But on the Marantz there was a separate low pass filter. I don’t miss it nor do I need it, providing the Denon is doing what it should correctly. Il be better digging the old digital manual out for the Marantz first to find the option.

[@Test-Pilot1194]

ksaunders359 with having to do too much research though, I think the LFE is variable because of the different types of speaker available in the market nowadays, some people decide not to use a subwoofer, but full range speakers instead, I think that’s why it’s variable anyway. Either way, in a HT the LFE opens up at 120hz. So I just leave it there at its default. 😀☺️

[@lysholmrado]

LFE channel plays frequency's from 120hz and lower during movie's. Your actually loosing sound from your subwoofers if watching a film. I also see you have your front speakers set to small. If you going to run that low of a xover why not run them large?

[@Kpaceguy]

Because they play louder when crossed over higher and I found the quality of bass that comes from my speakers vs the subs to sound different. Not necessarily worst or better. But different. I like the low bass to come from my subs because I can calibrate it. It's also far louder. I also listen to music so when I do the subs go off and the speakers go full range of course. I'm aware that the LFE track extends to 120hz but overall I like it lower just because of the sound I get overall.

[@dangr123]

Unless your main speakers can go down to 20 hz, I'd set them to small. Crossover at like 60-80 at the lowest. Any decent sub is just going to do a better job at that frequency range than almost any tower speakers.

[@nexxusty]

Those are front L/R. Your speakers Hz settings are ALWAYS completely independent of your sub. On literally every receiver that exists. I'd refrain from giving advice on HT if you can't even comprehend a visual speaker setup screen on any AVR out there.

@@Kpaceguy k

[@GSP-76]

You have the phase settings incorrect. If the subs are in front facing you, you generally leave them at 0...if they are in the rear facing in, you out them at 180. If they are on the side walls facing in, use 90 if available). If your subwoofer has crossover frequency on the back of the sub, always choose the highest available number...your receiver will handle the actual frequency via LFE.

[@JagadeeshPolepalli]

Yeah I did the same thing..I have turned the nob all the way to lfe and let the reciever handle it and made changes to LFE in the reciever as well

[@keywestjimmy]

There are no hard rules like that. Rooms, distances are unique. He mistakes polarity for phase.

[@GSP-76]

@@keywestjimmy Of course there's no hard rules...your ears are the rules...but generally speaking that's how you setup the subs...I made a mistake when setting my 15 inch 1000 watt sub up on both the phase and frequency...once I put it to the maximum frequency and changed the phase to 90, my sub literally sounded and felt twice as good. The phase is less important than the frequency but on some subs it makes a huge difference.

[@GSP-76]

@@JagadeeshPolepalli You should never change the LFE frequency...it's usually defaulted to 120hz and you should keep it there because you may be missing out on some frequency if your other speakers aren't capable of doing lower frequencies well. This is even more important if you have bookshelf sized speakers. On my previous front tower speakers, I had 5.25 inch woofers that really couldn't do frequencies under 80hz well. It wasn't until I got my current towers that have 8 inch woofers that I was able to set them to 60hz and get great sound.

[@keywestjimmy]

Gurvinder Parmar It seems you get it, but simply suggesting settings is kind of meaningless or maybe misleading. Here is what I would suggest. Setting phase on a sub: Since it's easier to hear a null than a peak do this. Reverse the polarity of one speaker (swap + and -) and play a test tone from 20hz to 200hz. Next, from the listening position, ask someone to adjust the phase so you hear a DIP in sound level at some point during the test tone. This creates a null point. Swap your speaker cable back and you're done!

You’re description isn’t accurate. For one if you cross both @80 you’re not loosing any frequencies. It’s not a hard cut off. Crossover’s have different slopes. Most common are 6, 12, 18, or 24 db per octave. So if you use a 12db per octane crossover @80 hz on you’re mains it will be down 12db @40 hz.
