I can relate to the comment around 32:00 about simply having the extra power to not have to worry about anything. I have a BasX A3 that was running my Polk es50 and es35 - plenty of power for my apartment environment; never going to run out. I recently upgraded to the R200’s and R350 and will add a XPA 3 in the spring. I’ll never need that kind of power here, but at least I’ll want for nothing - and be somewhat future proofed. And if all the neighbors decide to go somewhere at the same time, then I’ll have the extra power to be able to open these babies up full throttle! Lol. Cheers, everyone! Happy Holidays!

This is explaining technical elements of speaker-amplifier interaction using technical language, to a non-technical audience. This is not the first time this guy has done this. I was hoping to get the information I need to make a decision on the power I need for the speakers I want. I’ve watched 17 minutes of this video and we’re not even close to explaining the formulas to make a decision. Without the formulas it’s just a guess.

My home theater journey began decades ago with a 19" TV mixed brands of speakers and a small sub. I'd fire up the Laser Disc, pull my chair close and had a great time. Soon after, 1994 or so, I bought a standard definition CRT projector that was 8 feet wide and 4:3. I had a real sub, and mediocre 5.1 receiver and the LCR speakers were Tannoy PBM 6.5 studio monitors (2-way 6.5" woofer, soft dome tweeter). It was okay, but it sounded very small. I thought I needed bigger speakers to fill my room. But the first thing I did was add an Outlaw 200watt per channel amp. That made those little speakers fill the room beautifully! The amp made huge difference. It's now 2023, and I am still using that 5 channel Outlaw amp. I'm also still using the 18" Bag-end sub from 1994. A good amp is a long-term investment. You can add more channels, and you'll likely need to replace the pre-pro and projector every 6 to 10 years. But a good amp will be a good amp for decades.

@MrSmith-zo6po Жыл бұрын

Great video, thank you. I have a Denon 3700H running a 5.1.4 setup in a 10 X 12 ft room. I have a BasX A7 for the 5 ear level and have the AVR power the heights. It sounds great, and when I added the external amp, I didn't really notice a difference. I don't think I needed the external amp, but bought that one for two reasons, I wanted one that would go into standby mode when the AVR powers off, and I got the A7 if I wanted to go to 7 ear level speakers in the future. Since I don't listen at loud levels, I'm probably using only a few watts - 4 max, so I didn't need the external amp for the power. It was really just ease of use and future set up.

I added my first external amp to an avr this year. Noticeably better separation, clarity and more natural sound if using pure direct. Very loud listening is a total game changer. You can’t understand what overhead means until you hear ultra low distortion at max volume. I am now intrigued about going full separates. Avr is a Yamaha RX -A2A Amp is a old Marantz Mm9000, thx certified 170 watts with all channels driven. Bi-amp the front and rear channels into SVS ultra bookshelves. Sounds killer even in my big room with terrible acoustics.

@robertmason9465 Жыл бұрын

Well explained have Amps drive your speakers will be a big benefit. When I sold home theater years ago this is how I explained it when you have a AVR I will compromise the audio quality the AVR has to do a lot. So in choosing AVR depending on your budget is to choose one with Pre outs for separate amps And the more efficient your speakers are the less amp power is needed to run the speakers without distortion and amp clipping

To answer the question, no, I do not run a separate power amp. I have a 7.2.4 system and all my speakers are 87dB sensitivity. My AVR is 150 watts R.M.S. into 2 channels and has an internal 600 watt power supply. Occasionally I crank it up pretty loud and I've never detected any distortion. My sound system consists of 4 SVS Ultra Bookshelf speakers (2 for the mains and 2 for the side channels), an SVS Ultra Center speaker, 6 SVS Prime Elevation speakers (4 ceiling mounted for Dolby Atmos and 2 mounted on the back wall for the rear channels) and 2 SVS SB-3000 Subwoofers. The system is powered by a Yamaha Aventage RX-A8A 11 channel AVR connected to a Panamax M5400-PM Power Conditioner.

Hi guys, bi-amping doubles the damping factor from the amp, which does allow for better driver control . Apart from that, amplifiers age much better than processors, sole exception being Storm or Trinnov I think.

@bigdogaxis Жыл бұрын

A good sign that external amps may be needed is if you experience ear fatigue when listening to your HT at ~80 dB. Your system could be causing distortion. Having power headroom reduces the opportunity for distortion as well as improving clarity of sound.

@BuffSquadBigBenni Жыл бұрын

I believe your sensitivity formula is flawed. There are several factors that affect spl. Sensitivity stated by manufacturer is in a anechoic chamber. In real life applications the spl (db) will be higher, depending on the room and acoustical treatment. If you don't run you speakers in full range (most people don't) they will also need less power. When you have multichannel output the combined spl will also sum up and be higher. Just some things to keep in mind for real life applications.

Quick comments. For the math you guys did for the power needed. 2 factors were missed. You calculated just for 1 speaker. Each speaker would add 3db from the beginning. Also, important to consider is if they are 4 or 8ohms.

7.2 with AVR but it’s Klipsch RF7iii & RC64iii & Klipsch surrounds on a flagship Pioneer 901 (which will anyways be upgraded next year with an E-Arc capable AVR) so I feel I’m good with all these efficiencies ^_^ Don’t know how I feel about adding atmos since I don’t think I’d be able to take advantage of it much at all. I guess it depends if video games get popular with Atmos

@zelko0768 Жыл бұрын

Thanks guys very informative. One thing that I always get stuck at is speaker wattage compared to power requirements. So let’s say your speakers are rated at 100 to 200watts what power would you require. 100,200 or watts per channel?

@andrewz925 Жыл бұрын

If your speakers are rated for 100-200w RMS then ideally you would use a 200w RMS amp because that ensures you're able to extract the maximum amount of safe performance out of your speakers, but an amp as low as 100w RMS would also be okay. You also want to make sure your amp is rated for that amount of power at whatever impedance your speakers are, for example, 200w RMS at 8 ohms for both the speaker and amp.

What is the wattage needed to double the volume +3db with a sub on? It’s double without but it’s definitely less than double with a sub on at, say, 80 hz. If I had to venture a guess, I’d say 35-40% higher but that’s just an estimate after I added a sub to my system.

Even crossing speakers over at 80 Hz, typically you get a much larger, full sound out of a floorstanding speaker then you do a bookshelf speaker. With bookshelf, you still have to put them on stands so they take up the same footprint.

I played Edge of Tomorrow and thousands of movies in full range with B&Ws and a Marantz 8002. It only went into protect mode while playing Dragon Age Inquisition which had a crazy spell sound effect. But I did own a Denon for 1 week and the drivers on my B&W bookshelves at the time were moving full excursion (bass was shocking for a bookshelf). It would not have survived Edge of Tomorrow - this was music during a commercial and the speaker was giving a recital and competing for gold in gymnastics (I was afraid the kevlar driver might break and fly towards me) 😀

@Youthman Жыл бұрын

I’ve never personally seen that happen. AVR’s are capable of driving 8ohm or 4ohm loads. I drove an entire Klipsch system with an AVR and the RF 7 series are 8ohm nominal (meaning average) but they dip down to 2ohms during certain frequencies. I do believe that people who have 4ohm speakers would however benefit from adding a dedicated amplifier.

When i bought the Marantz 8015, i was looking for new speakers. Emotiva T1 towers are 4ohm. I called them and they advised me not to run them on the avr because that reason.
