Thanks, for making this line array setup video. I unboxed my S510s a couple of months ago, but have been a little apprehensive to setting them up. Tech support explained to me the setup steps, but seeing it done for me is much better. You filled in some of the fine points of the process and what to listen for that were still a little nebulous.

Yessssss to longer form videos! YESSSSS to line arrays…getting a pair of 510s or 812s for Christmas! Many thanks 🙏🏼 for the vid

these types of setup videos are immensely helpful.

This is the video I’ve been waiting for! Watching a REL (arrays for that matter!) get dialed in by The Dude himself! Def not going to see this setup at the local BB. Feels like a front seat at CES! Thanks John!

Thanks John. Amazing insight. Amazing product. I will add to my REL and complete my line array one day. ...soon I hope.

I really love the no-nonsense way you think John, the way you anticipate people that are silly is great. I really like your stuff.

I fully share all of this configuration! this is the best setup in the world to get huge bass by multiplying the subwoofers! no disfration from loudspeakers to loudspeakers and multiplication of the power per line;) I have been using this principle for 10 years with 8 passive subwoofers independent of each other (4 left + 4 right) without any speaker + amplifier filter external qsc4050hd, the problem encountered was starting to complicate because the sampling by micro analysis I situate the volume of the 4 subwoofers at too large a volume (-18 db)! So I managed to find the secret by analyzing a single subwoofer without connecting the others (4 ohms) and then connecting the other 3 (1 ohm! 4: 4 = 1 ohm) And it works it's absolutely monster ! but you can't do a one-line configuration in one pass ... great, beautifully explanatory video;) first: Obligation to configure only one subwoofer by the measurement microphone second: plug all others in uplink Result: The first subwoofer is configured in perfect micro analysis under its 4 ohm impedance and the electrical principle of connecting the other subwoofers thereafter generates a division by 2 of the Ohms value to the next subwoofer therefore in a configuration of 3 subwoofers we get 1.33 ohms from the entire subwoofer line and therefore a triple multiplication of the power delivered by the power amplifier with a basic analysis 🏅 The huge advantage of its REL subwoofers which has an LFE xlr input and an LFE xlr output is that you can adjust only one subwoofer by the analysis microphone of the preamplifier without connecting the others and connect the other 2 by the LFE xlr output then on the same principle mentioned above but as a separate power amplifier + passive subwoofer it works on the same technical principle but as an integrated amplifier in the subwoofer;) 👍

Exceptional quality 👌 of detail.

Very helpful, thank you.

I have a pair of G1 MK2s. Just this single pair for now though I plan on building the array when I have a little more space. When John sets the volume and crossover points on the S510s what does that correspond to on the G1? We don't have the click settings but that screen in the front. I am assuming 30hz for crossover and maybe 15-20 for volume? I have pretty big front speakers and my volume is currently set nearer to 25 than 15. Thank you.

I can't believe how much this dude's approach clicks with me...

I really like this video. And, as a music lover/audiophile, I can certainly tell that John has dealt with my people before. Many times. I love some of his word choice and prioritization, they're killing me. I believe him, though. And damn, a guy's whose set up +5000 subwoofers, that's one that you listen to.

Great video thank you, now what track/tool you are using for this TuneIn process? Thanks again.

They do really like the sonus faber concertos or the concertino's.. Because i have them to with the original stands, i see you have the stands of the sonus faber concertinos

Hi, can you provide more information on dealing in the crossover and volume on the first sub

Wow. This is next level base discussion. I just put my subwoofer on and turn it up and walk away. I'll be watching these very closely. Thanks for the education

I have a pair of s510’s, no 6 pack yet. I set them up using sneakers as the first anchor set in this video. My mains are set perfectly with proper rake angle. However, they have adjustable spikes. The REL’s do not and sit directly on a carpeted floor. The problem with this is that my speakers are perfectly leveled, but my subs are not and are clearly leaning forward compared to the mains due to issues with the floor. Should I add shims under the foot rails to make the s510’s in perfect vertical alignment with the mains? This would wind up decoupling the subs with the flor and a latter amount of the rails would no longer be touching the floor. Any advice?

I’m curious after seeing this setup, which essentially fees like two tower speakers in front of the room. With the Line Array Setup, is the impact of “room mode” in low frequency space, which seems to necessitate subwoofers generally, not relevant? If so, would one be able to achieve overall better sonic performance with a true full range speaker with +/- 3db @ 20-25Hz, provided they are powered adequately for the room?

If anyone was curious, a Nimitz Class Aircraft carrier weighs approximately 1,209,523x more than a No. 25... But I cannot move one without help. Great video as always!

One day I’m going to get John to come and setup my system … I live in South Africa 🇿🇦 😉😅

The description of the resonant bass drum head having a delayed and perceivable attack is something that might need another examination because that’s not what happens. I’m an audiophile so I pay attention to, and appreciate sound quality. I’ve also been a serious drummer my entire life, and have been professional full-time for over half my life (I’m middle aged now). I’ve played over 6,000 live shows all over the world, plus studio work both commercially and also engineering the sessions myself in my own studio. I’ve played concert bass drums in orchestras as well as marching bass drums, and to this day I’ve been listening to a large (40”+) bass drum played practically every night for the last 23 years. I’ve heard it acoustically, recorded, and close mic’d with an in-ear monitor mix literally thousands of times. There is no second transient. It doesn’t do that, at any dynamic level. NO drum does that. Perhaps you’re hearing a room reflection as the “second transient” because that’s much more likely since it would take a given distance to hear any type of latency. Either way, I’d like to know the recording you reference when you hear this, the actual time mark too if possible. I’m always willing to learn something new, but as of right now this seems like you’re describing something else. Thanks for making the video.

Same level of detail for a stereo pair of Rels next please!

I started with a pair and now own a full REL G1 MkII 6-pack, (main speakers are Dynaudio Evidence Masters with Boulder 2000 series electronics and Transparent Opus Gen-5 cabling) and my favorite track to demo it is "Chimes" by Bruce Stark. There is basically "nothing" in the song (it's a Bösendorfer piano and, well, chimes!) anyone initially identifies with needing "sub-bass", but when you kick the line arrays on you literally get an ENTIRE hidden layer of details, spatial cues, harmonics and decay from the instruments and the "room" the recording was done in that just makes everyone's jaw drop whenever I do it...And yes, I can just about knock my house off it's foundation on EDM and techno music, lol, but that's really the "lowest hanging fruit" with the 6-pack's capabilities. I tell everyone you just have to experience the REL line array to "truly" understand it but once you do it'll damn near impossible to go back to just a pair of subs, lol.

What happens if you setup an array with the exact same settings? Do all three basically couple to each other and act as one giant sub? And then what does auddessey room correction do if there are two sub outs? Is it basically trying to correct whatever sub is connected to the reciever, making it out of sync with the other two subs? Or does using the xlr cable between subs ensure the same signal from the processor is repeated to each sub?

Hi, thanks. Is a line array of 212SX possible (in a big room of course)? If so, can a 4 pack be enough and relevant? Thks

Where do you listend? At your seating position? Or next to the subwoofer? I have magnepans so theres coming sound from the back of the speakers also

Love this but CDO i mean OCD im feeling anxious just thinking about me tuning over and over mannnn

hi, I have 6 REL subs but they vary in size 8" , 10", 12"....should I place the bigger ones at the bottom ?

How loud are you listening when making the original adjustments to gain and crossover

The explanation of line array setup is very helpful. I am certainly no expert, but curious about the following. 1. Is the distance of a driver from the floor important? If so, why? I note a stack of 15 inch woofers is much higher than 10 inch woofers. 2. If the mid level sub is the fulcrum, why not dial that in first? It will roll off at a higher frequency than the bottom sub, therefore the bottom sub crossover would be set to blend with the mid level sub roll off. 3. Could the balance and gain of the mid and high bass be achieved from 1 sub using DSP PEQ rather than a sub for each frequency band? 4. Wouldn't the bass be cleaner with the subs placed close to the wall behind to minimise blurring from sound reflecting off the wall? DSP could be used to delay the mains to ensure impulse synchronisation/phase. 5. Is there interference (cancellations etc) between the drivers in an array? 6. If bass is omni directional, why is toe in relevant? 7. With all subs reproducing almost equal bass frequency bandwidth but in difeents ways (roll off, crosover, gain), wouldn't the overall response feature peaks rather than be than flat? Cheers

Is this the same tuning method used when used in a home theater system?

Which track is it where you're listening for the "double skin" sound on the bass drum, please? Is that "Sneakers" track 4? ("Cosmo...old friend") TIA!

I found a local Dealer hear in Germany who sells REL subwoofer. Do REL ensure that the vendor knows this many important positioning things?

how does one tune for LFE w/out blowing the high-level settings?

Hi guys ! Interesting, however, my room it's too small to accomodate 6 RELS. I'm thinking instead to only build one tower ( right channel ) instead of 2 towers, Would that work , what do you think ?

if I have a double stack. can I just put the speaker on top of the stack to get perfect alignment ??

one day I will have these

I'm assuming this can be done with the new TX line?

Not that sure what your doing when there's no music I'd love to know how to set up rel sub properly I have an older stentor 3 which is nightmare to set up right

That looks like so much fun to do. Time to save my pennies.

Can I confirm when you’re listening to the timing when setting up placement, you listen at the location where you’re setting up and not at the listening/seating position? Is that correct?

In 9:30, when you unplug it, you had previously connected it to the amp as a stereo set up or only to the left channel? I mean are you listening only the left channel and the sub connected to it?

Hi Rel, I was wondering if your next Generation HT line subwoofers going to go lower in frequencies, and also would you consider using dsp just for the ultra low frequencies only. For example down to 20-22 hz analogue and below 20 hz DSP. Best of both worlds. I am sure if you did use DSP you would be using it more effectively than anyone else.

Do I need the blue-tak for this? Lol

How do you hear for the correct location when you're not in the listening position?

Can a line array be done with the REL T7x or T9X??

So they all play the lowest bass frequency? And the higher up on the stack you go, the higher the cut off feequency?

This method applicable to a dual subs set up?

Can you recommend another song to use? Don’t have a CD player and the song isn’t on Apple Music…..

So is this a 5 way configuration

Tried that Sneakers track…what the hell? What little bass is in that track is sporadic and way in the background, played through dual T5i REL subs already well set up. Puzzled. Maybe someone csn suggest a track with a solo bass line played low and clear

Greetings, Besides safety issues, why not add another pair of subwoofers and make it an 8-pack? If bass moves vertically, as John has stated in previous videos, why not add a fourth subwoofer if one desires so? Thank you.

Can you do a setup with 1 und 2 subs in a room, too? A real setup would be nice. Those subs are not connected...i am rly struggling to setup my new s/812. Either I have badass base but it hurts my ears over time or my ears are ok but i lose the badass experience...

The mains in this video are not connected so this is a "dry run" . . . nevertheless VERY instructive ! thank you!

There´s only one thing that´s stopping me buying a 6 pack, having absolute perfect pitch i want to hear EVERY single bass note. I´m looking at Velodyne DDplus series where i can fine tune with DSP so that every single bass note can be tuned to my listening position . My listening room is full treated. How can you fine tune with DSP or perfect pitch?

Please send me 6 Carbon specials. Thank you!!!

Let's do line array, and pay us ten grand!

i just get a pair and put them in the left and right corner of the room so my wife does not get mad.

Maybe if you used DSP with adjustable time delay, you wouldn't have to do all this physical moving around nonsense

Since the crossover frequencies are not the same for the individual subs, the phase is also different between them. This entire setting up meter long wavelength devices a millimeter back and forth seems nonsensical.

Rel is UK just remember :-)

Am I the only one who finds the bookshelves comically small vs the subwoofers😅

Is he acting? Like showing you what you should be doing when tuning your system? Or is he listening to something that we can't hear?

This is just a ridiculous attainment for your average person.
