If the crawl technique does not give you the result you want and the settings on your A/V receiver are good then it might be that your subwoofer is not large and powerful for your application. To benefit from the full potential of a sub it needs to be capable of pressurizing the entire room. When selecting the right sub model you need to calculate the entire volume of the room including opened adjacent rooms and not only the listening area.
Great video, thank you. I have a fairly good system. Paradigm 60 Studio speakers running 5.1 on a Denon AVR-1912 (which I just got). Somehow, I can't seem to get the sub to give me that deep bass sound. I like a bit heavier bass on my listening. Any suggestion? I have my sub sitting behind my TV and my speakers are beside my TV.
I did this by myself without even knowing its called subwoofer crawl and everything. rather i used a simpler idea and that was to keep moving the sub until i hear good bass in my seat... it worked. i am a genius.
I have two woofers, they are 9.5 ft tall and weigh 700 lbs/ea. The crawl however could be done with any subwoofer. Just place a small sub at your listening position and use it for the crawl then once you find the optimum spot place your larger sub there. I didn't do the crawl, I just put one on each side of the room about 4 ~ 5 ft from the front wall. These are dipole subs so they work a bit differently. Bass response across the eleven seats is very uniform.
Also my diy JBL 4645 sub is a bit large to pick up and it might break the sofa! LOL I could move the sofa out of the way and place the sub in this location and use pink noise with microphone and spectrumlab where it paints a colour frequency spectrum. Its quicker to move the microphone around and it will see nulls dips and peaks. The aim is for smoothest frequency response.
Crawling around youll ears will be a few many inches below the seated height level! So you might as well do, The Crouching Tiger Itching Dragon where you crouch and walk around slowly with wideband pink noise. The sub will filter off the rest of the lows.
Also subs in a cinema are many feet above seated ear height be radiates down and around uniformly. You might have range from 50 to 65Hz where the bass is in huge dip and that is not good. The sub might be doing well from 20Hz to 45Hz? Place a another sub of the same on top of the first one and might improve the 50Hz 65Hz it might have a bit more strength on the 20Hz to 45Hz. It doesnt happen overnight it can takes days to set-up.
hmm Yes but what if i have a subwoofer with 2 x 12" ? where to put..... check my video don't know where to put the box its 150 cm and 45cm each side long cube model .. it's different from classic sub...
I used to have the same woofer setup right next to my TV. I would sit down to listen and hear literally no base at all. Yet everyone in my house was freaking out and complicating about me shaking everything down stairs. So I got up and went half way down the stairs, and the bass was so strong it felt like my heart was going to explode. I did this (as directed by a friend, before this video came out) and it turned out the sweet spot was dead center in the room.
I know what thats like to have a large fireplace and chimney sticking out into the room, my room is the same but the room I have my system setup in can have the woofer in the corner of the room thank goodness. but the "Subwoofer crawl" is a little extream and I have never come across any one doing it before
WOuld you say that having the woofer in the corner of the room because then the bass can bounce of the walls and it will give it a bigger boost in sound then what is there?
Sometimes, but there's no hard & fast rules, especially when you have a room like mine where it is all open along the left side and a large fireplace and chimney sticking out into the room on the right-hand side. I have my sub at the back of the room between the 2 rear surrounds and i get fairly even base whatever chair i'm sitting in. Just trial & error...

This is a great video and the tip (subwoofer crawl) works great. I used this video to help me find the location of my sub a while back.

My problem is I can't have the subwofer sticking out anywhere I need to "hide" it.
