Four Subs, Seven MORE Setups | Gradient Squared, Endfire, and Other Fancy Subwoofer Arrays

[@jthunderbass1]

One thought. If you were buying brand new subs, buy ones with networking, what this does is revise you to use one or two outputs from the mixing Consol but then you can do all of this processing inside of the speakers on your laptop.

[@MichaelCurtisAudio]

Yes, having processing in the speaker's is certainly one approach to give you more processing flexibility.

You are awesome!!! I constantly use you vocal EQ!!! Our band has 4 members and we all sing lead and harmonies. My speakers are JBL SRX835p. And they are paired with SRX818sp subs. The 835 tops have nice mid throw to help vocal projection. Your vocal EQ techniques and compression work well for us. Man…. If you are ever in St Augustine Florida…. To have you at our shows would be so awesome. Most of our shows I have my 2 subs stacked forward with an 835 on top and other 835 on a tripod. On an outside show, I’ve put the subs center&sidebyside with each 835 on tripods. Both these setups throw subs well with no alleys. Some shows the subs are separate on each side of stage with 835’s pole mounted and the alleys are prominent 😢 but it’s the venues and it’s what we can do. Again …. You are awesome!!! Thank you 🙏🏻

You're very welcome!

i LOVE these "setup review" videos :D

Thank you so much!

Michael- I have an event coming up in Oct. of this year. The room is wide rather than deep. I have 4@ EV ETX subs that I plan to use. From the front of the stage to the sound booth will only be 60 ft. On the right side and the left side of the stage will be 75 ft. ea. Please advise. BTW- I plan to use 2@ EV ETX 35P on each side. I know they only have a 60 deg. horizontal pattern on the horns so I want to direct them appropriately. If I don't have enough coverage, I will use a ETX 15P to help with fill speakers- delaying them as well. Please advise on the bass set up. Many thanks!

[@DustinRadtke]

I have an outdoor gig and I have 4 qsc 118s. If I used your first layout and did them 1 backwards, 1forwards (set to Cardioid in the dsp) and then repeated that with the next two in the line would that work to form one big wide cardioid? The stage isn't tall enough to stack them.

[@L0r1T0]

i have the exact same question 😅

[@MrNicknayme]

Super Nice. Thanks.

[@NonnyStrikes]

I have 8 18inch in total. 4 b52s (older style subs yes haha), but I stack those on the edge of the stage. The stage is elevated. So 2 b2's on each side, stacked on each other. The other 4 subs are below the stage, with a false front stage. Just a sheet covering where the subs are. I have tried spaced 3 ft apart each, coupled all 4, and I can't really tell which is best. I'm assuming spaced between the 4 under the stage is optimal. If I'm incorrect, lmk. Thanks!

[@rickneiheiser5091]

Can you use different types or brands and still get the results? Is there any info on building a cardioid all in the same box?

[@MichaelCurtisAudio]

As far as mixing brands, you certainly can, but you would need to make sure their spl handling, phase response, and magnitude response are all similar.

[@renkchaos4480]

Hi Michael, what would be the best way to set up for and out door 360 degree dj event with four subs?

[@gringoloco543]

I've loaded some subs into Ease Focus, and tried every configuration you talked about. I just get these boring circles. Do i need different software? And Ease Focus doesn't account for room modes or wall reflections, which are a major factor, especially in smaller rooms.

[@QuicksilverSG]

With a delayed arc set of four subs around 5-6 feet apart, how much delay would you recommend for the two outer speakers?

[@nunojorgenjstudio7954]

I've been seeing a lot of V shaped configurations like v__(stage)__v (where the Vs are subwoofers making a 90º angle). Can you talk about this, pros and cons of this configuration? (If you understand what I mean)

[@MichaelCurtisAudio]

Hmm, interesting! I can't exactly envision what you're describing. Could you drop a link to a diagram?

[@john26660]

Would you do a sub analysis where the stage is at the side of a rectangular room? I come across this many times at conferences. Think of a high school gym but your stage is in front of the scorer's table.

[@MichaelCurtisAudio]

In that particular case you want as wide of a pattern as possible, so either a single stack of subs if you need multiple, or an inline gradient to help keep the pattern wide.

[@john26660]

@@MichaelCurtisAudio Thanks!

[@TheJmbf10]

Is it possible to do an inline cardioid blending different sized subwoofers (Like 18s in the front and 15s in the back, with similar build construction)? Would this work?

[@MichaelCurtisAudio]

As long as their levels and phase response are matched and you're not driving the smaller sub into limit.

[@lifeonfourstrings]

Hi Michael, both great videos, I have had the opportunity to experiment, play and navigate some challenges where I was able to pivot to a different setup due to the ever lasting battle for realistate . My only question is does any of these approaches change when using native cardioid subs?? I mainly use Infra and Vsubs both being cardiod boxes. So does this make gradient arrays ineffective.

[@MichaelCurtisAudio]

Great question! All of these setups are still viable even with native cardioid enclosures.

[@dantowell2804]

2 questions, 1-is half wavelength measured from the middle of the speaker or edge of the sub. 2-can you mix 2bass reflex and 2 bandpass together ie 2 yamaha dxsxlf and 2 yamaha dxs mk2 for a 4 sub arrangement. great informative vids by the way .

[@MichaelCurtisAudio]

1. You can measure from either place, just as long as it's the same reference point for each. 2. Thank you! As long as their output and phase response are similar and you're not driving any of the boxes into limit you can.

[@YiPSKiPP]

I have some passive Bag End infra subs, but I don't have the processor which apparently lets them reach down to 8hz. Without the unit they only get to about 60hz. Is there any way I can get them to go lower without buying the processing unit?

[@MichaelCurtisAudio]

I don't know much else other than mandhandling the response with EQ and testing to see how much headroom you got.

[@Fexiheit]

Is it a good idea to combine flown subs with subs on the floor or wouldn't you recommend that?

[@MichaelCurtisAudio]

I will use some floor subs in front of the stage if it's a large system with flown subs to help the pit audience have some low end that images from the stage instead of above them (since they'll likely be listening to front fills from the stage, not the main PA). You can also use flown subs to cover 31Hz - 80Hz or so, then use some infra subs on the ground to get below that (down to 13Hz in Meyer's case). With such long wavelengths stacking them in a row doesn't narrow the beam as much, and you can do a delay arc to spread things out.

[@Fexiheit]

Hello Micheal, what prediction software did you use here?

[@sw-ww8368]

It's called MAPP 3D

[@esoundsom3804]

If you have 4 diferent subs like 2 RCF 8006-as subs and 2 RCF 8004-as , what could be the best setup if you want to use the 4 ? And keep the good job, we learn so mutch with you, best regards from Madeira island in Portugal

[@MichaelCurtisAudio]

The goals of the show and the audience coverage shape will ultimately determine the "best" setup for each show. So, without that information it's hard to say.

[@esoundsom3804]

Sory i forget that, the goal is a stage 8x8m with a audience in front 50x50m and the less possible sub in stage@@MichaelCurtisAudio

[@xkurtknox]

can you do a video with 6 subs?

[@2020sav]

Most of your array videos are built with single spk cabs. I really see more double speaker cabs.
