BOSE SUB 2 BEST SET UP FOR THE DJ. OR WILL THEY CATCH FIRE?

After using them in every mode and configuration possible here is what i found out for the DJ. Stand them up side by side and daisy chain them to get the best best bass response from the Subs.

[@Acoustic_Theory]

What you called 'doubling' in this video is actually known as 'mutual coupling'. When you have subwoofers separated apart by more than 1/4 wavelength, their output becomes uncorrelated, so each doubling of subwoofers only provides 3dB extra output, but when they are closer than 1/4 wavelength their output becomes correlated, so they are working together the most efficiently, and each doubling of subwoofers then gains you 6dB extra output.

[@Acoustic_Theory]

There is still sometimes a reason to place subwoofers separated on either side of the stage; this tends to concentrate low frequency output in the area between the left subwoofer and the right subwoofer, which is helpful if you have neighbors to one side that shouldn't be disturbed. Also if your 'left' and 'right' main speakers are separated very far apart, and both are far away from the subwoofers, then the subwoofer sound can begin to seem separated from the output of the main speakers - both in time and in sound quality. Lastly, if your stage isn't elevated, then a cluster of subwoofers in front of the stage may not be tolerable.

You can move them apart by up to 50cm (20cm gap between each) and they will still couple up to their highest frequency (around 200Hz). This also has the advantage of slightly reducing the output to the sides, if you need to avoid cancellation nodes from side walls.

Can you please show your setting on the subs, and maybe use a DB reader to measure the SPL at full volume? This sub setup is my goal, I'm at my third Sub 2 so I'm almost caught up! Dying to see the full potential of this setup.

[@skinjobs1237]

working on it.

I see you have a pair of S1 Pro. I was debating on get a pair of those or a pair of QSC K8.2 to pair up with my (2) Bose Sub2s. Which of the two would you recommend?

[@skinjobs1237]

The Bose S1 are nice but i needed more power for my rig and i got 1 L1 Pro 16's.. Now it sounds like a live concert on and off stage. With the 4 sub 2's and the 2 same subs in the L1 pro 16's, well need i say more? I sold both of my F1 stacks, and both of my S1 Pro's.

[@MarcusFranklin-sg7xd]

@@skinjobs1237 Yeah I bet that sound like a concert Noooo Doubt!! 👍💯💯💯💯

[@DJBpartyTV]

If you have a left and right channel, run 2 subs on left and 2 subs on right. Don't daisy chain them. Use an xlr splitter. Your running your subs mono. The subs sound fine flat on the ground by the way. I think you might be running them improperly. I have tons of videos showing that they sound fantastic laying flat. 😎

[@skinjobs1237]

I have seen them all trust me (your vids). lol. glad you chimed in kid. Using the tonematch mixer with all my subs on the right channel in mono they sound better and allow me to push them harder with out messing with my tops. My sound meter shows high numbers this way. And i have other videos of me laying them flat vs standing, just going to leave it to personal pref. What i hear and feel coming from them they sound better standing side by side, and the numbers don't lie. You get more DB with coupled, not in stereo, and in pairs of 2. The great thing about Bose they just sound great so the coverage is easier to manage. And as a DJ they really don't have a lot of set up advice just users and reviews. So i treat them like any other speaker and look to engineers who do sound for a living. They all say placement is key, wiring, coupling, and eq'ing. I will stick with that, and look forward to your next video. Thanks!

Maybe it's me but I don't run anything mono. If you run your whole system mono and then you run your system stereo you can hear certain artifacts of the song including the bass that will sound a little narrow vs wider. I use to be a sound tech for festivals and outdoor concerts. In my 20 years of DJing. I've never seen anybody run their setup in mono. Now if it's just the subwoofers that might be okay but if you're running the whole system like this, I know you're losing a lot of spatial sound in your audio. I look up at hooking a DJ equipment like you would just surround sound system at home. Would you run all of your speakers off of the left channel? Also if you want more sound out of your subwoofers and you do want to run them mono maybe you should get an XLR splitter that's male to female. This way you can plug in to both your left and right output at the same time and out to one XLR into your sub. That way your sub gets both the left and right audio. Or you could easily achieve this by running both left and right to the sub and then Daisy chain your subs as such but you'll need way more XLR cable. If you're running all your subs mono, do you use the XLR outputs on the subs at all? Hopefully you're not running subs off one channel and mains off the other. 🤔😎 What's your method?

@@DJBpartyTV Hi there! FOH engineer here ;) Running subs in stereo is pointless, subs are omni directional and cannot produce a stereo image on any useable scale even on our D&B SL -Sub array as the listening position will never be the same for everyone so its just wasting a ton off energy for maybe a small handful of people getting sub stereo in the entire festival. So that's not quite accurate information you are passing on here! So comparing anything home audio to this is pointless. Changes and differences in setup all depends on the room and position you are setting up in. Sometimes ill run a stereo setup, other times the room is just not correct and reflections will cause comb filtering in a stereo setup so you are better off just running a single column of speakers in mono. Running the 2 sets of subs on channel 1 and 2 and the rest of the system on 3 and 4, as long as the tops run a stereo signal its all good!

[@DJBpartyTV]

Does the same rules apply to column array systems? (Evolve 50, JBL PRX, Bose Pro16s) Do the rules change with powered versus passive? Do the rules change with DJ setups versus live event setups? Do the rules change with mixers that have one volume fader versus mixers with left and right volume faders? Do you still run mono subs if they are placed on the left and right of stage with speakers pole mounted to the top? If so how would you run audio in these types of scenarios. I don't want to sound like I know everything and I'm always interested in learning. 😎

[@skinjobs1237]

I feel you sir. I have seen many set ups. And some run subs mono and others don't. This has always been the debate right? I guess it will always come down to your needs at the time you are playing, and if you are just Dj'ing or having a live event with mics and different players. We are in the same boat, not knowing everything. But we agree on 1 thing and that would be that these Bose speakers are the truth. After 12-15 years of use I love them. @@DJBpartyTV

[@snapsbyreyes]

Also, what is the proper way to provide electricity to these? What kind of power strip/conditioner are you using? Would this type of power blow a fuse or am I *ahem* tripping? lol

[@skinjobs1237]

so i was using just regular power strips and these subs would dim lights and flip breakers. I switched to Furman ss-6b 6 outlet surge strips. problem solved. I also use Furman conditioners. Also 12 gauge xlr on everything. All cables power and sound should be high end.

[@loudspeakertestsmorebyaida3804]

Does one these SUB 2s shake more than a $2,900 1,500 watt SVS PB16-Ultra subwoofer?

[@skinjobs1237]

I will just say that when i play out with them, I go into the mixer and turn the BD down by 3 sometimes 6DB because it just hits so damn hard i don't think i will ever need it to hit that hard. Dialing it back allows for cleaner sound and the people love the way it sounds. Full and warm, not muddy and or repelling.

[@papijosb5150]

Could you gift me one of the Sub2 Bass pls 🙏
