I am a high-school physics teacher by profession. Your videos are my to-go place for understanding the technicalities of sound engineering. Your lesson plans are good and your message gets across very clearly. You are a very good teacher. .. And you are doing all this for free and with all the gear required to put all this here. You are an inspiration for me. You are a very good human being. The Earth needs more people like you. Stay blessed and in good health.
Thank you Mahady - my original inspiration to get into the technical side of show business was a high school chemistry teacher who also taught me how to rig and focus lights. I hope you inspire many of your students in the same way! 😊
Amen🙏
Oh he's not doing it for free lol, he gets money from RUclips... but I totally agree with you
Okay, I'm two years late on this comment, but once again I am amazed at this man's ability to combine technical knowledge with an innate ability to teach. This is my "go-to" site for ANYTHING having to to with sound systems.
Thanks for the comment! I'm actually a trained teacher so my teaching ability is hardly innate :)
I realize this video is 6 years old but omg do I wish I had found it sooner! I’ve been DJ’ing for a little over a year now and basically have been RUclips/self taught in everything including speaker configuration. While watching a video on speaker size vs venue size, this video came across my feed and I am so glad I checked it out. Your explanations are clear and concise, and demonstrated exactly the way I needed for it all to come together for me. Thank you thank you thank you!! I’m about to go redo my set up now so 🤞🏻🎧
Just wait for the bass drop 🫨
That's great to hear Liz, very glad the video was helpful and all the best with your music!
As someone who struggles to be taught i have to say this video was brilliant. You are a natural teacher! Thank you very much
You're welcome Jack! Hmm, I'm not sure anyone 'struggles to be taught' - perhaps you struggle with learning new things but the teaching is the responsibility of the teacher 😊 Good educators will have a variety of tools which can be used to teach the same concept in different ways, as different people learn in different ways. Thanks for watching!
You are a born struggler
I feel like I'm in a classroom every time I watch your videos. I learned a lot. T.Y.
You're welcome, thanks for watching!
I always learn something new from your videos. Thanks a lot for sharing! 👍👍👍👍
All I can say is WOW. You are so smart and yet you can make it sound simple enough for a person like me with a brain injury and cognitive defects, to kind of understand. Thank you for sharing your knowledge. I appreciate you.
That's wonderful, it's great that you are able to appreciate and learn from the video 😄 All the best with your music!
Thank you so much for such a wonderfully clear explanation of how to connect up an active subwoofer. This has perplexed me for some time and the answer was so straight forward but also comprehensive for the different systems. Your style of explanation and the diagrams are simply brilliant. I’m looking forward to watching other videos from you.
Thanks for watching, very glad the video was helpful!
Simple, complete and very clear. Excellent work! Thank you.
I watched this as musician that has very little sound engineering knowledge. I was hoping to gain some knowledge that would allow me to live mix my drums. Your video was just excellent. Very clear and you were mindful to explain all the different terms. Thank you so much.
Thanks for watching, really glad the video was helpful!
you won a subscriber when you said "but... you know - there is never too much bass". Cracked me up.
Wow, I've learned a lot from watching your video that answers EVERYTHING I would like to know about the subwoofer. All great explanation, details and demo are much appreciated! Thank you so much!
You're most welcome :)
Best explanation I've heard so far on this subject, clear, concise and thorough-Thank You.
You're welcome :)
Do any one noticed that this man is very intelligent, always happy whenever i see his new videos,God bless u sir.
Thanks for supporting the channel Rob!
it's the love of the bass the bass the bass lol ...seriously he loves what he does and it shows
I've seen a number of his videos and truly what he doesn't know isn't worth knowing. The absolute thing about Bruno is you ALWAYS get a prompt reply without fail.
Indeed...very interesting
I wish more sound engineers would teach as you do! It is so important to not be bias in your PA system set-up and understand how a different application can be useful.
Yes! I wanted to know how to connect 2 passive Speakers and 2 passive Subwoofers with a non-powered mixer.
He explained well, lots of people just explain powered speakers.
Thanks for watching Nicolas!
I feel like I am the best sound engineer right now after listening to this wonderful explanation. Your explanation is top notch. Keep it up and God bless you.
Thanks for watching, glad the video was helpful!
Hi Brother Bruno, I like what you're learning us in all your videos. That's a very good job, thanks a lot!
You're welcome, thanks for watching!
Thank you for the excellent explanation. I learn tremendously! Awesome work! :)
You're welcome, thanks for watching!
I've been searching YT for these kinds of information for weeks! Very in depth explanation! You sir have a gift. Thank you
You're welcome, thanks for watching :)
its been too long, i ignore this video, when i watch it' i was wrong' its more interesting the way he explained it! his a good instructor thanks u sir 'for sharing!! more blessing
Perfect, I have just bought a sub for my gigs, cant wait to use it :-)
Hope you shook lots of dust out of the ceiling ;)
Nice tutorial very useful Sir.
Hi Bruno, I can't thank you enough...your video was so helpful in enabling me to set up my new sub to my power amp and to my passive speakers ....great instructional video Bruno ....Thanks again. Dave Smith
Great news, very glad the video was helpful. If you would like to support the channel please consider signing up to become a patron at www.patreon.com/glbproductions?ty=h Every little bit helps!
Wow! This has been the single place on youtube where i have found helpful mention and explanation of using an active sub with passive speakers. Thank you!
You're welcome, thanks for watching!
Wow... I love watching videos that actually have correct, useful information and explained easily enough for the average person to understand. I recommend that ALL DJs listen carefully and learn from this video, as about 90% of DJs have no idea how to set up, and or tune their speaker systems, or even know what equipment is necessary to have for proper sound reinforcement.
Thanks for your vote of confidence! Much better to have an older or second hand system that sounds ok than a brand new system that sounds horrible because it's set up wrong ;)
Wow! I get it now, great video.
This is an excellent tutorial. I now know more about subwoofers than I thought I needed to know. I am considering using the 2nd connection scheme using a group out on my mixer; however, I have a monitor controller that I’d like to integrate that accommodates 3 pairs of speakers and a mono sub out. I’d love to see a diagram of this setup. Thanks for the great vid.
Thanks for watching Tom! If you have a monitor controller that should be the device to handle the crossover duties - the best ones have a variable crossover frequency, or one that is selectable between 80-150Hz.
Clear concise informative- subscribed to your channel- brilliant instruction! Thank you Bruno
I've never heard anyone spoken with such clarity im my life..
Thanks Mark.
Bruno on the loose again 😎👊🎤 another awesome supplement👍
Cheers man 👌
Okay Sir i got now what you mean and Thank You again for the clear information
LOCKUP THREAD .
21:56 "There's NEVER too much bass"... your videos fill a void to the sound enthusiast in me...alas SAE has shut its doors in Singapore for the Dip... ah well... looks like you're the goto for my lessons! Thanks Bruno... really appreciate you taking the time and effort
Yes that was definitely a loss but you can't really blame them considering it was due to a lack of students... Thanks for your support!
Great video I use it for training for my roadies when doing gigs.
I enjoyed this entire video. Although I was familiar with most of this information, I think it is a great tutorial for new sound enthusiasts.
Thanks for watching!
Thank you for an excellent tutorial! Very informative and your explanations are very clear. This was a tremendous help! Thanks again.
You're most welcome.
What an amazing teacher you are. I have never met someone in any subject who taught like you. Crystal clear wordings. Thank you, sir.
You're most welcome, thanks for watching! 😊
Thank you so much. In my second system: From Monitor to Fullrange speaker; Main out L/R to Sub and I got crazy sounds like my way. Now I try again. Thanks you
You're welcome!
Really nice! Very useful. Congrats!
Thanks for watching!
Hi Bruno. In the UK, we usually call those power leads kettle leads :-)
Best and most thorough explanation.
Excellent analysis-and-explanation of the different configurations
very very simple and easy to understand Video, i really thank you a lot.
You're welcome, thanks for watching!
Well done Nicely explained Thank you very much Bruno

One of the most informative videos I've ever watched on RUclips. Thank you!
You're welcome Kevin!
Wow! Such a great explanation and tutorial on introducing a subwoofer into a PA system. Thank you so much GLB :)
You're most welcome Rick, thanks for watching.
Thanks my friend. You answered me many questions. Definitely subscribe...
I'm loving all your videos. I'd love to see some gig logs or examples of you actually mixing an event because you seem to be a very talented sound engineer
Thanks for the support Guy. To be honest with you when doing events I'm normally much too busy with the actual event to think about filming anything, I guess I have a one-track mind :P
+GLB thanksfor the lovely dimple explanations.. sir.
I have a pair of 3 way full range speaker with mid/highs and Lf speaker of 10 "..I want to use my old tube 100 watts amplifier with proper crossover for my 15 " subwoofer..( passive).both the amplifier and subwoofer are in excellent working condition..will I get the desired effect if tuned properly with passive crossover.
your comments sir..
Thank you sir🙏 only because of your lesson I learned PA system, mixer and music now i am able to handle small events, small cultural musical concert . Your simple and unique teaching skills is great so so easy to understand. I am huge fan of yours . 🙏🙏 thank you so much sir .
That's great to hear Asa, keep up the hard work!
This video was hillarious! Your pause moments while listening to the beat for referencing, staring directly into the camera had me rolling! 🤣 Great video man
Thanks for watching 😄
nice beat great vibe...
thanks ,, awesome detailing
You have explained so much that I was not sure about, simple terms, easy to follow terms, brill bro, keep 'em coming
Thanks for your support Ken!
This video is amazing. You teach in a way that difficult things become easy.
Glad to hear that, very happy the video has been helpful.
Thankyou for this brilliant video, I have just bought an active speaker system and was totally confused on how to connect my amp/mixer to the speakers. This is by far the best video I have seen on this subject. Thankyou once again.
You're welcome, thanks for watching!
Thank you so much for the video. I’m trying to learn this stuff and this was the most helpful video so far. Only thing I would change is maybe do some head bobbin when u play the music. Or some Dancing.
Noted on the head-bobbin' ;)
Thank you for this great video I've learned a lot from you! Your lesson is easy to understand specially for a person like me who has a very little knowledge about sound reinforcement. I'll be watching all your other videos.
Thanks again!
Blessings!
You're most welcome, glad the videos have been helpful. Let me know if you have any questions in the future :)
Thankyou so much for this very informative video. I have been trying to find out how to use an active sub but still drive my passive tops through an amp. Your information was so easy to understand and I am now getting the best use from my set up. Thanks again Bruno.

I've been watching you for a while already.. My impression about you has been that you're not only very talented in what you do but that you also have the gift of teaching and that is very important on the teaching of such a complicated profession. Thanks to a great teacher.
You're welcome Carlos! You're right, I'm actually a trained teacher and my day job is lecturing at a technical/vocational college - RUclips is just a sideline ;)
Excellent job Sir!, greetings from Kingston Jamaica.
Thank you, greetings from Singapore :)
Fantastic explanations of the different methods. As a bass player myself, I agree there never can be too much bass! Ha ha!
I’ve recently started doing karaoke for a local company, and your videos are so very helpful to provide the correct information I need to try and convince the manager of the problems with his current systems. Your ground loop video and this one should really help my arguments as to why we need a sub, and why his floating ground is not only dangerous, but unnecessary.
Oh yeah don't fool around with lifting electrical grounds on PA systems - you are asking for a very bad, very expensive accident.
@@GLBProductions Unfortunately, the owner was unwilling to reconfigure his system to include an electrical ground, so I quit the position. I'll be building my own system soon, and will be including a sub woofer. No other Karaoke companies in this area have one; so I'm hoping this will give me an advantage in getting booked.
Yes sir Bruce so educational, thanks for so patiently explaining on details Engr. Ive gain a lot of ideas when it comes to this field.
This is awesome
Thanq and appreciate your efforts for sharing.
This is the most informative video I've seen. And the information is practical! Thank you!
You're welcome, thanks for watching!
You sir are knowledgeable, witty and an amazing teacher... Thank you!
You're most welcome!
very informative...
Thanks for watching!
Hello Bruno :o) Always I like to refresh the info, which I already knew. It is a good idea of that kinda very useful repetition from the different pro source. Moreover, it is a good referring and refreshing possibility to call, in a case of the forgotten stuff .... if that somehow can happens. Thank you very much !!!! Appreciate that !!!! Have a good one :o))
I'm my humble opinion your learning style is the only way to go! Have a good one.
@@koartistent >> Yo man !! Thank U !!
@@koartistent Grazias Nicolas :o) LEARNING .... it's a never ending and life long story !!!! :o)
Have to say your ability to clearly explain a technical side of todays active type speakers is commendable. I for one did build speakers back in the 80's using only 3 way cross overs non ported passive type of speaker designs. Philips components. Technology has come along way since then. Its refreshing to learn how signals are being separated and handled. Information as such was not as readly available as is today. However, theres a lot of old technology still being used out there. Some musicians just prefer it that way. Personal taste. Sound reproduction is really an art in its self. In different applications or venues. Choices are endless for equipment. Finding what fits ones needs. You have taught some very vaulable points to consider. Thank for sharing. Cheers.
Thanks Marcus! You're right, I have seen gear from the 80s and 90s still going strong, especially in clubs and pubs where they are not being moved a lot.
Very detailed and thorough explanation for the various techniques and the underlying principles. I am professional DJ with an electronic engineering background. Still learned something new from your video about using aux send for subwoofers. I use 18 channel digital mixer, 6 aux sends. This technique will help me to reduce the feedback during live performance. Thanks
You're welcome Mirchi, aux-fed subwoofers is a great technique to know.
"There's never too much bass" - Love
yeah, its true, we love rebassed
I bet he loves his D&B
*For the casual people, who are being not deep enough emerged into ELECTRO~ACOUSTICS rules of physics .... actually, it is a terrible statement !!!! :o(*
Thankyou very much! :D
I always pay credit where it is due and you my friend know your shit. You covered everything in great detail and in a clear manner. I learnt a lot so cheers keep it up mate
Thanks for watching, Matthew!
Brilliantly dumbed down for people like me just starting to learn about subwoofers ,active speakers connections. Thanks a lot
You're welcome Alfonso.
Gracias... very, very, helpfull....
Glad to hear that!
+GLB Productions why you don't use jbl passive speakers on your videos please do one video with the Stx series
I'm not loyal to any one brand and generally just use what I have available.
GLB Productions ok but try to use one because I want to buy one but don't know the quality
+GLB Productions hello I have buy a Panasonic max700 and its total output power is 25000watt can you please tell how can I put it on its total output power
more base ... ;)
i mean bass hahahaha
what people dislike this stuff? thank you so much you answered all questions and I learned heaps. cheers great vid :)
People have different expectations which are not always in line with what I try to achieve in the video ;) Thanks for watching!
You have a very clear English speaking. Very clear to us non-native English.
I'm glad that is helpful to you 😊
Excellant presentation. I learnt much regarding the connections to be made from the mixer to the Active sub woofer and full range speakers, both active and passive. Thank you very much.
You're most welcome Abraham.
THANKs bro, you help me a lot, youre the man!!!!
Thank you so much, watched 3 videos before this without luck! This was exactly what I was looking for!
You're welcome Matt, thanks for watching.
thx v much for the info....explained very well and clearly
I've learned a lot today from your video can't wait to go and apply the knowledge you gave to the public, big up bro!!!!!!
You're welcome Sobhekwa, thanks for watching!
Great! Systematical and meticulous explanation! Very helpful. Thank you.
You're most welcome Rio, thanks for watching.
Bruno, excellent video on active and passive subwoofers and the pros and cons of each. Keep up the good work!!
Thanks Sidney!
Always very easy to understand. Thanks Bruno
Oh man, seriously, you're fantastic. It's not only the theory and practical knowledge, it's also the way you present it (and I think you have a funny bone too). Big like :)
Thanks for watching my friend!
Very good video; thorough. When I found myself asking, "Well, what about this though..", you answered it!
Yes I've been teaching live sound for many years so have a good idea of what are the questions people tend to ask. Thanks for watching!
for PA solutions and knowledge..i find this channel is the only truth out there..
Your RUclips channel is the first that made me subscribe right after watching the first video. It’s amazing how clear what you have to say is, thank you indeed!
You're welcome Stenaldo, thanks for your support! 😊
Thank You! I finally understand how to connect active and passive subs now! Great Video, God Bless!
You're welcome, thanks for watching!
I hereby by the power of Texas I baptized you as Master Tech Professor.
I enjoy every video you make. Great job brother 👏👏👏
Glad to hear that and thanks for watching!
That's what I called EXPERIENCED!!! Well explanation sir. Cheers from Indonesia
Thanks for watching!
Great video! Nice to listen to someone who knows step by step what they are talking about. Thank you!
You're welcome Raymond, thanks for watching!
Out of all the videos I looked at. You really explained the connections very well. I have the same mixer you using.Also, im moving from external amps to powered speakers.Less gear I got to handle.,Thank You!
Yes, eliminating the power amplifiers definitely reduces the bulk of one's setup, although it does mean carrying more in the way or power cabling, distribution boxes etc.
Nicely shared and articulated so we all can understand this complex area of audio configuration! Thank you.
You're welcome, thanks for watching.
Very informative, and precise explanation of all concepts explained.. Very well done sir..
Thanks Scott, glad the video was helpful :)
Excellent- the most clearly thought out presentation on this topic i have every heard--keep them coming!!!
Thanks for watching Jim, appreciate your support 🥰
I learned a lot from you. Your English is so simple to understand. Thank you so much
You're welcome Moses, great to hear that!
Excellent explanation! Short and clear expressions in plain language. Thank you!
You're welcome :)
Wonderful explanation !!! I am so glad to follow your instructions. I now understand why I need a sub woofer and what's it needed for. Thank you very much 🙏
You're welcome, thanks for watching!
Super informative, and well structured video. Thank you.
You're welcome Niels.
