After watching many of John’s videos, I finally pulled the triggered on a pair of T/5X and couldn’t be happier. They sound incredible. Due to my living room arrangement, I could only place them on each side of the couch but was still able to get them to sound as if they are a part of my speakers (B&W 707 S2). I’m literally sitting between the two subs and still got to pair them so well with the B&Ws that their bass appears to come from the B&Ws and not the subs. I connected the subs using the high level connection and also the .1 LFE for movies, which I should mention they do a fantastic job for movies as well. I had to turn the LFE level almost all the way down after my wife almost jumped off the couch while watching a movie. 😅

Can you tell me how to connect two rel t5x subwoofers correctly to the hegel h190 amplifier!? It has only four terminals! What should I connect and where??? I can't find anything!
Did the bass increase at lower listening levels? Like a loudness button can do? I do like to have that more bass sound at lower levels by buying second one.
I have 2 Rel subwoofers in my home theater. And indeed they are all set differently. There is no other way, because my home cinema is obviously not a mirror image or semi-semimetric. But it sounds great. It took quite a while to get it optimal, but if you take the time, then it sounds really good. And the subwoofers are really a must and very beautiful and well made.

Why do so many video productions insist on background music? It's annoying and distracting and usually really shitty, techno noise anyway. Otherwise, very nice information. I've been running 2 subs an now know why the left and right soundstage opened up so much. it was really strange at first and I toed in the main speakers a bit because it felt weird to have sound coming from, essentially, the bookcase and walls. But there it is, the mystery is solved. i'll adjust my listening with that understanding.
@@ВадимКлименко-в5ы You run an extra pair of speaker wires from you amp to the speaker-level inputs on the subwoofers. It's the best way because you get the best phase, level, timing and sound. The signal that the subwoofer gets is only a small fraction of goes to the main speakers. The load of the subwoofer crossover is easy to drive.
Why not? I wouldn't be concerned with any bass being absorbed if that's what your concern is. You can build a concrete wall a foot thick and likely still have powerful bass on the other side with some of these subs. I'm trying to mitigate bass freq and soundproof a room and the level of effort, mass of material and absorption techniques required to absorb bass or low frequency energy is absurd. I doubt it will even "see" your carpet in any meaningful way.
Thank you for reaching out. In our experience, having carpeted floors will not impact or hinder the performance of our down-firing subwoofer models. If you have any additional questions then feel free to reach out and we will be happy to assist.
Hi John, thanks for your explanation on a pair of stereo subwoofers, I myself own a pair of tzero's and a pair of t5x's and I'm thoroughly impressed by their perfomance, especially since they have such a small footprint! I have those t5x's for about a year now and even after setting them up in different places at my room to trial and error the best possible solution and sonic pressure inside my room I still encoutered some problems between 60-40 hz... Last week I decided to pair up my tzero's in my living room setup together with my t5x's, the t5x's running of high level right down from the speakers terminals and the tzero's running lowl level and set them up on the other side of the room with the phase adjusted to 180, and to my wonders that setup is working beautifully and fills in all the missing dips and do cancel out some peaks! But now it got me wondering, is there a possibility that the t5x's are to small for my room and speakers and do bigger subs make it easier to fill out those nulls and cancel out those peaks?
Thank you for reaching out, and for choosing REL Acoustics subwoofers for your home audio system. Choosing the ideal subwoofer for your room and system can help to achieve adequate pressurization in the room, though peaks and dips in the bass response are typically a result of the acoustics of the room rather than the choice of equipment. Using more than one subwoofer helps to smooth out peaks or dips in the bass response, though adding acoustic treatment to the room (diffusion panels, bass traps, etc.) can also help to tame acoustic issues in a room. If you have any additional questions about setting up your REL subwoofers in your room then feel free to write in to contactus@rel.net and we will be happy to assist.
Will a second subwoofer also help increase the sound pressure at lower sound levels; can it simulate a loudness function by increasing the lower frequenciez with 3 decibel?? (Double sound is 3 decibel increase, right?)
Thank you for reaching out. An increase of 3dB does represent a doubling the wattage of the amplifier, though an increase of 10dB represents a perceived doubling of sound. Adding a second subwoofer can result in increased output levels, depending on how you set their Level controls, and will also allow for fuller sub-bass output and a more balanced output from your system as a whole at lower listening levels.
Hola John!!! Una pregunta ... Es posible equalizar los subwoofers conectados con hi level input o no es nessesario??? Tengo denon avs x4700 e 2 Rel´s Q200E ...
Thank you for reaching out. When connecting your subwoofers using the High Level input it is possible to use their rear-panel tuning controls for adjusting the output, though we generally recommend against using room correction software while the High Level cables are connected. Instead we recommend running the room correction with the High Level cables disconnected, and then once the program has finished you can re-connect the cables and tune the subwoofers manually by-ear to blend with your speakers.
Thank you for reaching out. It depends on the specific model of subwoofer that you will be using, though in most cases with stereo pairs of subwoofers we recommend assigning one unit to right channel output and the other to left channel output, while also feeding LFE channel signal to both subwoofers if they are being used in a home theater application. For more specific information on connecting REL subwoofers in your system, feel free to write in to contactus@rel.net and we will be happy to assist.
Hi John! For dual subs, do you recommend fine tuning the left and right channels separately? Specifically, should I only plug in the left speaker/sub combo and do room measurements then repeat for the right speaker/sub combo? Also, is corner placement best for both subs or nearer (inside or outside) to the speakers? Thanks!
Thank you for reaching out. When tuning stereo pairs of subwoofers, we do find that the process is made easier by tuning each subwoofer individually to start. Then once each subwoofer is sounding good and is blending well on it's own you can connect both and make final adjustments as needed to their Level controls. Corner placement can work well for stereo pairs, though improved performance can be achieved by bringing the subwoofers out into the room and placing them just next to the corresponding main speaker channel. This will help to provide a more seamless blend between the subwoofers and the corresponding main loudspeaker, and since you will be using two subwoofers they will be less reliant on corner proximity to reinforce their output. We hope that this helps, but if you have any additional questions then feel free to write in to contactus@rel.net and we will be happy to assist.
@@RELAcoustics Just found the answer on your website! (it may work best to place the subwoofers in close proximity to the main speakers, just behind and to the outside of main speakers)
When tuning the right channel subwoofer in a stereo pair it is best to either disconnect or power off the left channels subwoofer, so that it does not produce any output, though you can leave the left channel main loudspeaker playing normally. Shifting the balance for the main loudspeakers away from the left channel will change the way that the right channel main loudspeaker performs, which will result in the subwoofer's tuning no longer being accurate once you adjust the balance back to regular stereo output.

Hello! Tell me how to connect your two t5x subwoofers to a two-channel hegel h 190 amplifier??? I can't find this information anywhere! Even in your user manual!!!
Thank you for reaching out. When connecting a stereo pair of subwoofers to your Hegel H190, we recommend combining the red and yellow wires for the right channel subwoofer, and connecting to the right channel positive speaker output terminal on the amplifier, with the black wire then being connected to the right channel negative speaker output terminal. The same instructions can be used when connecting the left channel subwoofer to the left channel speaker outputs on your amplifier. More detailed instructions, and a diagram showing these High Level connection instructions, can be found on page 20 of the T/5x's owner's manual.
Hi John, I m actually with a T7x (and it is pretty good) and i will add one very soon to expand the soundstage, do you think that i can add a T5x or Ht 1003 instead for more depth ?? My listenning space is about 25m2 in a room of 60m2. Thanks 😊
Thank you for reaching out. When you have a chance, please write in to contactus@rel.net and our team will be happy to provide a subwoofer pairing recommendation specific to your system.
With my stereo pair of s 510’s I have them locked in time alignment with my mains. My room is not symmetrical. The right side of the room has a cutout in the middle of the room for a desk and windows. There is also a tall dormer in the cutout. I have a difference of one click between the pair on the crossover, and difference of 3 clicks on the volume. Left is at 5 and right is at 8, so quite a difference in volume between the left and right subs. It seems this gives me a very even soundstage. Is it normal to have a room dictate such a difference between subwoofer levels?
The Level control difference that you described between these two subwoofers is within the expected range, and if the system is placed in a room with uneven dimensions then it is certainly possible that different Level control settings will be needed for each unit. The goal of course is for the sound of your system to be balanced and even from left to right, even if this means variations in tuning settings between the units.
My room is 3m wide 7m deep and 2.75m hight. I have the B&W 606 S3 with Marantz Cinema 50 which supports 4 independent subs. I listen to music and watch movies. Which sub do you recommend starting out with and later upgrading to 2 subs and eventually after that to 4 subs?

Thank you for contacting us. The T/7x is the closest equivalent to your T/7i from among our current lineup, though improvements were made during the design of the T/7x which mean that they will not be a perfect match sonically. Ideally, the best option will be to find a good condition used T/7i to match with the one that you are currently using.
Thank you for reaching out. At this time our subwoofer models are exclusively designed for home audio applications, though we can forward this feedback to our design team for potential future consideration.
Thank you for reaching out. Here is a link to our video on connecting stereo pairs of subwoofers to a single amplifier using the High Level input: ua-cam.com/video/cV_0G3GdPxQ/v-deo.html
@@RELAcoustics thank you for your feedback. What I understand from the video that you refer, is how to connect 2 subwoofer to 2 monoblock. Could you give me information about how to connect 2 subwoofer to 1 stereo power amp (not monoblock), that doesn't have balanced output?
@@egasimanungkalit3372 The same instructions will apply for connecting a stereo pair of subwoofers to a stereo amp as with connecting to monoblocks. Essentially you are connecting one subwoofer to the right channel outputs on your amplifier, and the second subwoofer to the left channel outputs. For more information, here is a link to our article on connecting stereo pairs to a single stereo amplifier: rel.net/blog/2015-07-23/how-to/connecting-a-stereo-pair-of-rels-to-a-single-amp/
A stereo pair of Tzero Mk.III subwoofers can perform well in this size of room, though in this size of room we recommend the T/5x as being the best option for pairing with your Magnepan LRS speakers. Compared to the Tzero Mk.III the T/5x has a faster and more responsive output, which will blend more seamlessly with these electrostatic speakers. If you have any additional questions about subwoofer pairing for your system, then feel free to write in to contactus@rel.net and we will be happy to assist.
Thank you for reaching out. Using two subwoofers in stereo (one dedicated to right channel output and the other to left channel output) offers several performance benefits, including faster and more responsive output, stronger dynamics with greater headroom, and a more balanced distribution of sub-bass output throughout your room. These benefits improve the sub-bass output substantially for both 2-channel music and home theater listening.
Hi REL, question for you. I currently am running a pair of KEF R11’s and paired them with a corner loaded T9i. It gets more than loud enough, even for modern electronic music, but I’m able to very easily locate where the bass is coming from and I don’t really like the sensation. Is that because the T9i isn’t fast enough for my speakers and need a S/812? Is it because it’s corner loaded? Is it likely not set up properly? Or do I just need two of them to balance out the sound?
Thank you for reaching out, and for choosing REL Acoustics subwoofers for your home audio system. There are a number of possible reasons for the output of your T/9x subwoofers being localized, including their placement and tuning. When you have a chance, feel free to write in to contactus@rel.net and we will be happy to discuss tuning and placement options to reduce this localization effect.
Thank you for reaching out. Stereo subwoofers can provide an improvement in performance in any system, including a nearfield desktop setup, though typically in this type of system a single subwoofer will suffice.
The problem is some rooms are L shaped or unusual shape and we don’t have the luxury of placing a second sub in a corner because there is no 2nd corner. You can overcome the limitations of a single sub with room correction, quality system and sometimes that is the best you can do. Setup properly with single decent sub like a T9X, you should not be able to locate the single sub in 2 channel.
I have a pair of s510s now and used to have a single s510 prior. What he is describing here is pretty accurate. It’s hard to explain but the phantom center imaging actually expands. You could get by with a single sub of course but the imaging is definitely better. I had a single sub for nearly a year and wondered why I waited so long. John is also a salesman and REL subs are not cheap so there is that as well.
After watching many of John’s videos, I finally pulled the triggered on a pair of T/5X and couldn’t be happier. They sound incredible.

Ideally, the best option will be to find a good condition used T/7i to match with the one that you are currently using.
Do you have plans to build a subwoofer for automobile market?
Thank you for reaching out. At this time our subwoofer models are exclusively designed for home audio applications, though we can forward this feedback to our design team for potential future consideration.
Hi REL, how to connect 2 subwoofer to my stereo power amplifier?
Thank you for reaching out. Here is a link to our video on connecting stereo pairs of subwoofers to a single amplifier using the High Level input: ua-cam.com/video/cV_0G3GdPxQ/v-deo.html
@@RELAcoustics thank you for your feedback. What I understand from the video that you refer, is how to connect 2 subwoofer to 2 monoblock. Could you give me information about how to connect 2 subwoofer to 1 stereo power amp (not monoblock), that doesn't have balanced output?
@@egasimanungkalit3372 The same instructions will apply for connecting a stereo pair of subwoofers to a stereo amp as with connecting to monoblocks. Essentially you are connecting one subwoofer to the right channel outputs on your amplifier, and the second subwoofer to the left channel outputs. For more information, here is a link to our article on connecting stereo pairs to a single stereo amplifier: rel.net/blog/2015-07-23/how-to/connecting-a-stereo-pair-of-rels-to-a-single-amp/
Would 2 Tzero MK3 subs be ok in a small 12x12 listening area? I have 2 Schiit:Vidars for my Magnepan LRSs and want to utilize the high level input.
A stereo pair of Tzero Mk.III subwoofers can perform well in this size of room, though in this size of room we recommend the T/5x as being the best option for pairing with your Magnepan LRS speakers. Compared to the Tzero Mk.III the T/5x has a faster and more responsive output, which will blend more seamlessly with these electrostatic speakers.
If you have any additional questions about subwoofer pairing for your system, then feel free to write in to contactus@rel.net and we will be happy to assist.
@@RELAcoustics Magnepans are isodynamic not electrostatic.
Are stereo subs recommended for home theater or only two channel systems?
Thank you for reaching out. Using two subwoofers in stereo (one dedicated to right channel output and the other to left channel output) offers several performance benefits, including faster and more responsive output, stronger dynamics with greater headroom, and a more balanced distribution of sub-bass output throughout your room. These benefits improve the sub-bass output substantially for both 2-channel music and home theater listening.
@@RELAcoustics thanks for your response!
Hi REL, question for you. I currently am running a pair of KEF R11’s and paired them with a corner loaded T9i. It gets more than loud enough, even for modern electronic music, but I’m able to very easily locate where the bass is coming from and I don’t really like the sensation. Is that because the T9i isn’t fast enough for my speakers and need a S/812? Is it because it’s corner loaded? Is it likely not set up properly? Or do I just need two of them to balance out the sound?
Thank you for reaching out, and for choosing REL Acoustics subwoofers for your home audio system. There are a number of possible reasons for the output of your T/9x subwoofers being localized, including their placement and tuning. When you have a chance, feel free to write in to contactus@rel.net and we will be happy to discuss tuning and placement options to reduce this localization effect.
You put it in the corner you get bass boost but it will be more easily localized - change position simply
i have mixed feelings but clearer sound is whats important
i don't supposed you recommend dual for a desktop setup do you? I don't it makes much sense.
Thank you for reaching out. Stereo subwoofers can provide an improvement in performance in any system, including a nearfield desktop setup, though typically in this type of system a single subwoofer will suffice.
The problem is some rooms are L shaped or unusual shape and we don’t have the luxury of placing a second sub in a corner because there is no 2nd corner. You can overcome the limitations of a single sub with room correction, quality system and sometimes that is the best you can do. Setup properly with single decent sub like a T9X, you should not be able to locate the single sub in 2 channel.
Enjoy these videos, bought 2 line arrays of REL S510's... but, don't take John's words as gospel-- more than anything he is a salesman.
I have a pair of s510s now and used to have a single s510 prior. What he is describing here is pretty accurate. It’s hard to explain but the phantom center imaging actually expands. You could get by with a single sub of course but the imaging is definitely better. I had a single sub for nearly a year and wondered why I waited so long. John is also a salesman and REL subs are not cheap so there is that as well.
