Excellent question.

I've worked as an E. Eng. for 22 years and have a passing knowledge of audio equipment, but of course am very familiar with the electrical aspects. This is an excellent resource - you are doing a good service here. There is so much misinformation online regarding these topics, and your content is very refreshing. Nicely done, subscribed.

I've been a performing musician for 43 years and a sound technician for 18 of those years. I performed in a club for the first time at age 17 in a band that included my two brothers. We learned to play together. We started out with very minimal and insufficient gear. Over time, we acquired gear and built a large, mismatched, under-amplified, sound system we really didn't know how to correctly use. Oh, we thought we did, but we didn't. Much of it, we'd acquired used. Our mics were a hodge podge of cheap, used relics. After about 15 years of gigging heavily in Virginia, North Carolina, and West Virginia, sometimes playing three 4 hour shows a week, we grew tired of carrying all that gear. We hired out our sound for the first time. Back then, there were many good small sound production companies for hire in our area. They were all very capable and we had great experiences with every one of the many we hired. One day, we hired an individual who was phenomenal. He made us sound better than we thought was possible. And he made a lasting impression on me personally. I didn't realize it then, but I was cocky at times because I thought I knew my way around all aspects of gigging because I had "paid my dues". This gentleman could have easily told me off and moved on when I insisted on using a cheap EV mic from their affordable line I had bought based solely on the brand name, ignorant of specs or anything else about the mic. But he didn't. I would tell him my monitor needed EQ adjustments. He'd try to accomodate me, but the mic was simply not a good vocal mic. One day, I failed to pack the mic and he used an SM58 instead. I was humbled. My world changed. I began asking him how he knew the SM58 was the better vocal mic and why he could get so much better sound than we ever did. I learned that he knew his gear inside and out and had built his system well and knew how to deploy it to accomodate different venues. There was no internet back then. I was hungry to learn what I didn't know and consumed every book and every tidbit of knowledge I could lay my hands on. A whole new world was opened up to me and I realized I only knew a fraction of what I so confidently thought I knew. I also learned that I can always gain knowledge from anyone in the field because there are many different approaches to the same goals. And I embraced the fact that I'll never stop learning. We finally grew tired of the bar scene and took a long break in 2007. After several years of working in a bluegrass band, then an acoustic duet, with a number of different sound systems and approaches, I now have a very compact but capable QSC system and I mix from the stage in our 3 piece cover band. Times have changed, and so have the types of venues available for gigging. In our area, there are almost no clubs any more, but many establishments called brewpubs that offer live music. But unlike the clubs and dance halls of years past, the proprietors typically have no knowledge of the infrastructure needs of a band. There is usually no stage. Often, tables need to be moved to squeeze the band into the building. The audience is almost in your lap not only while performing, but also during load in and setup. And, often, there is only one 10 or 15 amp outlet for the band. I've built and tweaked my system to meet these challenges. I'm almost 60 now, and although I move a bit slower, I still enjoy performing live and achieving a great sound at FOH and through my stage monitor. I still use a wedge to better hear and control the show. I use an ampless guitar rig. Our bass player is ampless as well and my brother plays electronic drums. They both use IEMs and have tablet based control of their own monitor mixes via wifi connected to my compact 16 channel digital mixer. I'm retired now and we're like children again, having a blast. I find your channel and a few others to be very professional and informative. And I've successfully applied knowledge I've learned here. Thank you for your work and your channel!

Cool story. And today really is the best time to be a musician. As a drummer I can tell you for around $

In 1971, I was working on WFDD, or "Fudd," which was the on-campus radio station for Wake Forest University.. Like most college stations it's public and educational programming for the most part. A lot of classical music of course. But the late night hours were turned over to the m😂usically progressive rock and roll. And experimental. The first binaural development was already to the point of mounting microphones in a 'head' with accurate human ear canals, etc. We didn't have a huge budget so we made our own by mounting a couple of shotgun telefunken on a tree facing outwards. Since we had no head, we put a square of thick foam between them. It worked. So we registered the programming with FCC, as the first ever live binaural broadcast!! Wow, that was a long time ago.. Go Wake Forest!!

Listening to your channel every now and then over whelmes me. Some times I feel like I know nothing about Audio engineering or even music production. I would really love to take a full time course on audio engineering, speaker designs and possibly music production

Thanks man! I've really learnt something there!

Often the HF driver has a different angle than the LF driver. Also, when the directive is "Here it is, make it work." move speakers around and even try turning them upside down if possible until it gets as good as you can get then EQ from there. Sometimes weird tricks work. Great video!

I was introduced to active speakers with active crossovers in the early 70's, and I've never gone back. Being able to couple an extremely low impedance power amplifier directly to a voice coil with only some fraction of an ohm dampens the system to such an extent that they follow the source signal with a minimum of distortion.

Another great, very helpful, video. We have a show(outdoor concert venue) coming up in mid June and I'm working my way through your AU videos. Many thanks.

In my listening room/bedroom, sound quality always precedes aesthetics. My 2.1 setup definitely looks DIY, but I love it and it sounds incredible. I have a 3 tier wood rack with my caseless Gigabyte motherboard on top (SSD and power supply zip tied under neath it). Second rack is my BSR frequency equalizer/spectrum analyzer with no case and transformer relocated further from signal wires. Bottom rack is my Yamaha RX-530 with case and rear panel removed, upgraded heat sink and transformer also relocated away from any signal wires. My first order crossovers are attached to the back of my JBL Northridge II cabinets using the speaker terminals from spare AV receivers. Makes it super easy to switch out the coils and caps to play around with low pass filters, high pass filters and crossover frequencies 🤘🎧🎸🎵

Excellent videos, thanks for all this great information. I was wondering if you can make a video on speaker crossovers. I am particularly interested in how to determine the total impedance and power handling of a crossover/speaker given the amount of drivers with their respective impedance and power handling. In other words, in a 3 way speaker you typically have a woofer, midrange driver and a tweeter. all connected to the crossover of which is rated at let's say 200w (rms) at 8 Homs. So how do we determine the wattage and impedance of the woofer, midrange driver and tweeter to be used so that the sum is 8 Homs at 200 watts (rms). ? I hope my question makes sense..lol Thanks in advance.

Great work and effort ❤

5:07 Out of "theoretical" curiosity... Decibel is a unit used to measure the _intensity_ of a sound, *or* the _power level of an electrical signal._ Are Sensitivity and "Sound *Pressure* Level" (SPL) synonymous? More clearly, is it just to say that the sensitivity (a specific sound level measurement) is expressed in SPL dB, rather than Newton/cubic cm for instance or PSI or whatnot describing actual _pressure levels_ ? Something is missing which makes this a bit confusing (at least for me lol)..

Great stuff Kyle! Love all your videos!

❤❤❤great info… my 10 k cost speakers only put out 83 db /1 watt etc…. Vary inefficient… so I have a 550 watt power amp at 4 ohms to solve this issue.. using a DB meter I get average spl of 85 …at 10 feet…

What about tube amps? They have less wattage (output), but can power my speakers without noticable distortion - when my monoblock amp have greater wattage but sound isn’t louder…

I konw this is an old post, but I find it interesting that if you use Excel to calculate out the log 10, you get 2.6 not 26

Thank you.

Please make video on 70v/100v Speaker system.

If you truly care about your speakers and want to get good speakers, learn the spec sheets. Or the important numbers, because there is no shortage. Good fidelity can be found in the specs. Similar specs mean similar speakers. That is if the numbers are honest. lol. And consider Pro Audio equipment for home use as an option. JBL. Kali, Presonus make some good items!

You provide useful information in this video, but I am left confused as to whether this is geared towards the home audio buyer, or the professional audio person (say, someone who needs to set up sound for a band.) Professional audio personnel may need to know max power, etc. But the home buyer typically doesn't care about these things since they are listening while seated quite closely to the speakers. And for the home audio enthusiast, where does listening come into play? You have completely left the decision making in the realm of specs (which many times are not available, at least in the completeness you've shown here.)

These principles apply to all applications of speakers. You’re right, in that there is another side to this. In my opinion, make sure the speaker is capable with specs and then make the final decision based on subjective performance.

Its an excellent video but I have a question. Four types of parameters are used for speakers by the manufacturers in the speakers specififation sheet, these are Continuous Power (RMS power), AES power, Programme Power and Peak Power. Could you please tell me the relation between these parameters. Thanks.

@@AudioUniversity While the levels I've seen vary wildly (from -20 to +15.6) It's probably best to be within a few dB of 0. It's my understanding that while the standard is -14 LUFS (which is probably 0.0 dB content loudness), KZread will only reduce the level of videos that are above that, and will not apply gain to anything below the target level. That makes sense, I suppose, so that someone's quiet video of snow falling doesn't get amplified to be just as loud as a rock concert. While I'm sure you understand the concepts, there are unfortunately far too many content creators who don't realize that falling prey to the loudness wars won't make their music any louder on KZread (and any other place with ReplayGain or similar), but will simply rob their music of dynamic range. That might be worth a video, actually.

The three questions when buying speakers should be: 1. Do you need new speakers? Experiment with what you have, te result might surprise you. 2. Does upgrading on your budget give you a worthwhile improvement in sound? If not keep saving your money and do look at second hand options (that is always a good option to get better price/performance) 3. Can you try the speakers you might want to buy at home without (much) financial risk? If you cant, keep looking. Be aware that most speakers need a few 100 hours to sound there best. The trial period should be 30 days preferably. I consistently answer the furst two questions with no. And I keep using my ESL 57 😁 the same questions apply to every part of gear.

What about active speakers? 😆

Hahahaha
