Not all amplifiers are the same and there is a clear distinction made between the way their output stages are configured and operate. The main operating characteristics of an ideal amplifier are linearity, signal gain, efficiency and power output but in real world amplifiers there is always a trade off between these different characteristics.
based on my research Powersoft, Lab and Crown are indeed the amps to have. personally i would go with Crown because i'm a Harman fanboy and Crown seems to have better bang for the buck while still offering great quality. i used to think QSC was that - bang for the buck with good enough quality - but i no longer think QSC is good enough. one potentially interesting amp brand is DYNACORD which seems to be a division of Bosch / Siemens of Germany.
18000watts at 4ohm? Nonsense. The fact that we normally use 3x 18s a channel on crowns is enough. 18000watts to 3 speakers would not sound better or bigger than 3000watts to 3 due to speaker ohms. The best advice is to use amplifiers with 4 channels packing about 2500 watts per channel at 8ohm. That way you can use high powered double 18 subs. The Lab 14k and 20k are good examples. 8 to 10 double 18s will rock any event and they'll only need 2 amps to do it. The other reason 18000watts makes no sense, is it just a high voltage? Which power supply/cable supports that kind of draw? Certainly not the ones on powersoft amps
We built a sound room/movie theater underground. We had 2, custom made 23" subs in our sound room.. we had originally purchased a power soft amp to run the subs but for some reason the subs sounded like they were starving for power so we purchased a crown 7000 watt amp that gets these subs flying out of there cabinet. When you lay into the volume on a bass heavy track it will make your eyes water it's so intense. As far as I'm concerned no power soft amp will do what a crown will do. Come on the name says it all. Power Soft! Not me I'm power heavy!
Lets be real here. That much power is cool but you cant enjoy it for long. I can attest to using Power amps back in the early 80's using High end Jbl, Altec Lancing and sometime Gouse speakers. I had BGW or Phase-Linear or some Crown amps and had to be careful because the 15" Voice of the Theater speakers would reach their linear length and one or two times the cone just jammed forward destroying the speaker with clearity. These were just 250 or 300 watt powers. If I worked the system right, everything worked and I went home with working equipment for the next show.
FYI you can now achieve in excess of 180kw using the full bridge class D amps from Brazil. IKR - I myself have a stack of 10k FFA amps I worked hard for but brazilians are at the fore front
5yrs ago, LIVE CAT 10 was introduced in the market with 5000watts @8 ohms per channel not bridge then now LIVE FET 10.10 is 10,000watts per channel @8ohms😁
Crest 10001 will still mop the floor with any of those because it's rated for continuous output, not short bursts like the new amps, also compare the distortion levels at high power. All these new SMPS amps are nice for the features and if you tour a lot but in 10-15 years they will be throwaway e-waste when the manufacturer stops servicing them or stocking the modules/chips/software.
15k @2ohms briged and 10k @4ohms bridged and one amp is so fucking big and heavy and if you running a concert you will need 4x soo its not gonna be easy to transport at all and keep in mind the powersofts are slim rack units which are not heavy and easy to transport. Also the powersofts are rated 18k @4 ohms briged AT CONTINUOUS power not bursts.
I have about 5 of the QSC PLX3602 and i love them they sound awesome. However, they don't compare to these amps. These amp are one step above the 3602. peace !
What are the last two amps please put some links in the description to where to find them or at least give me the names and model numbers. This is terrible get rid of the graphics please 😞
I will turn my Amplifier up to 1 trillion watts RMS the entire cosmos will be my speakers subs mids and highs when the amp is turned up planets stars and arts in heaven will be shaking and trembling
125 volts × 20 amp =2500 watts 30 amps = 3750 watts now 250 volts x 20 amps 5000 watts 30 amps 7500 watts fyi the most amount amperage on a circuit breaker 80% it will heat up and trip . Is this false power with big capacitors discharging for a microw second?
Amplifers have something called crest factor, being able to output 18000watts overall doesn’t mean it has to draw 18000watts of power. K20 specifically draws about 10amps on 240volt (before clipping)
The powersoft k20 give you more watts per channel it gives you 9000 @ 2 ohms and the x8 is 5200 watts # 2 ohms and the pkn h8 gives you 9200 watts @ 2 ohms.
You cannot judge an amps buy it wattage just like that .Wattage in s important yes .But the frequency of which the amp plays is important to know if it's best for bass or for mid . I have a qsc 1850hd and a rmx2450 which is more powerfull.But believe me the 1850 play a deeper bass hence that's my bass amps for my 4 1500watt 15 inches blastking speakers .they beat the hell with bass .
Brazilian high voltage amplifiers will shit on all pa amplifiers , pa amps are limited to ac voltage from the main . Brazilian high voltage are powered from 12v batteries run in series from all the way up to 400vdc and those amps are .5 ohms stable full range
esos que salen son originales, tengo un amigo que compra las replicas directo en china del 2 y hay labgruppen de 10000f, el trajo unos 20000f suenan muy durisimo, lo unico es que son 220v
is that it??? we have here in the philippines powered by live. category 12 power amp. can drive 22k watts rms speakers. im not quite impressed by the wattage you have shown. thats mid level here in phils. no offense.
research nyo po presyo ng crown at lab gruppen. at ikumpara nyo sa presyo ng live at turbulence. power output lng lamang dito sa pinas pero pg dating sa specs lamang yung crown at lab gruppen.
Hay otras marcas mas económicas y de igual wattage que esos q presentaste en este video y con la diferencia q trabajan a 2 y a 1 ohmios y soportan más trabajo q los crown.... He usado todas esas marcas y crown no es para trabajo pesado y es muy caro prefiero marcas como TechVOX, QSC, lab grupen, american audio tienen mejor respuesta que esos crown
Saludos estos amplificadores tiene el dampig más alto que un american audio solo tiene 600 los mensionados en el video tienen 5000mil mejor calidad de sonido por eso su costo claro el american Audio hace el trabajo y es económico
Esos crown lo malo es cuando dañan no son tan comerciales con los repuestos tengo crown y siempre paso x lo mismo pero esos power soft son muy comerciales y trabajan muy bien los e visto trabajar x 18 horas al dia x 5 dias y me dejaron sorprendido son bestiales
You can only trust the 8 ohm power output specs, 3kw max per channel on a 32 amp plug forget anything higher, if its 3k per channel at 8 ohms brilliant as it will run 4 subs per channel at a 2 ohm load continuously at about 750 Watts per sub x8 total, this is with impedance rise to 8 ohms with some drops to 4 ohms where the amp will still only be doing 3kw per channel even if the manufacturer says 6k per channel at 4 ohms lol,, this is bullshit, if the amp is 3k at 2 ohms per channel then not so good as it will almost always be no where near that output even driving 4x 8ohms in parallel down to 2 ohms per channel, it will be at about 8 ohms with rise and the 3k at 2 ohms will be about 1400 at 8 ohms so about 350 Watts per sub continues, basically nothing,, so if your going to buy a new bullshit amp get one that's above 2500 Watts per channel at 8 ohms and that's what you will see, but saying its 8k per channel is unbelievable bollox, most of these new amps run on 1.5mm cords, 16 amps rated, the ffa 10000 has two 20 amp inputs for a real 3k per channel, the lab gruppen 13000 has one 16 amp input and under test conditions the most I see it pulling is 20 amps at 240 volts so 20x240= 4800 then - 20% for efficiency loss =3840 divide by two = 1920 Watts, and guess what?? That's exactly what I see it doing max per channel at 8 ohms 4ohms or 2ohms,, you can't get out more than you put in, these amps are not magic
research nyo yung presyo kung ilang turbulence raptor at live fet25k ang katumbas ng bawat isang amp nyan.. lalo na lab gruppen at crown. baka isang amplifier plng isang unit na ng mini sound dito sa pinas..
