"Besides that, X4 is capable of burning 18SW115 coils." There you have it....i got asked a while back if i was investing in any of the new X4L ( my racks are all X8 and T604), my answer was that even with plenty of 3000W RMS subwoofers in my stock i don't own any speakers that cannot be destroyed by the X8. |

The big nuance is that Powersoft does deliver true to its specs. The things that I have read about not delivering their specced power are totally NOT related to their own (powersoft) specs. Besides that, X4 is capable of burning 18SW115 coils. If it gets that dependent I would say you do not have enough rig for the gig. Things are probably different in other scenes, but I would say that's the case in 99/100 PA world.

Certain things in life, can only be verified by trial and error. Only in Speakerplansland, are such things tested, from the comfort of the computer desk, and screen.

to nutshell this thread then..
Folks: "powersoft does / doesnt do these things... and are pants" kyle / kutty / etc: "we own mountains of em, a: they do /don't and b: theyre effing great" folks: "naaaaaaah, we've seen a test on a bench, and some figures, what the F**k do you lot know" obviously, is a bit more nuanced and less black n white than that, but....

If anyone has been to see Sinai/Iration recently, they'll know the X series do the business. Iration playing tnt roots at dubcamp , definitely more than a few milliseconds. |

I'll trust PP's tests over yours, thanks. Also, they very clearly do not state that power is continuous sine wave, because as discussed, the real world does not require almost anybody to actually power that. When they do, they commission a K22 from Powersoft... if you don't know what that is, you don't need to know. 6dB crestfactor noise bursts of 200ms (AES) or 500ms (Meyer) are a much more usable measurement figure, for the real world of compressed, heavy dance music. 12dB crestfactor for these periods is indicative of almost everything else. Where the issues really lie, for me, are with amps like the LA12X that use only 8ms and 20ms bursts for their ratings. Sadly the XTA APA4E8 hasn't been reviewed by PP, but I have gone through their own spec sheet in detail. It has a lot of storage capacity internally, and the output side is super strong, but the limit is still going to be the power supply - perfectly reasonable, given the focus on touring, and the real world. Let's have a look at some world-class touring 4 channel amps, shall we? Sinus goes first, various burst signals second. XTA APA4E8 All channels driven (230V) RMS sine wave long term continuous power with all channels run simultaneously (over an hour assuming 20 degree ambient) 3000 W (4*750W) one hour Lab Gruppen PLM12K44 L'Acoustics LA12X aka CAMCO Q-POWER14 d&b D20 - no measurements of D80 Linea Research 44M20 Powersoft X4 And here's some info on XTA's test types, which are close to PP's, and why: Isn't data lovely?

Its not the same as long term heating power / real power, or it is not with a signal other than a continual sinewave. Its the RMS voltage of the sine wave while it is playing, but not long term.

"RMS means Route Mean Squared, it does not mean continual power, or real heating power." No, Root Mean Square means exactly that! Here: Edited by Earplug - 13 September 2019 at 12:24pm |

I was unable to measure even ~400W continuous per channel on the X4, if I remember correctly. If Powersoft says X4 is a 4* 1600W amp.. it could be OK! But keep in mind it sold as 4* 5000W amp, total 20000Watts which are very, very far from the reality. This is the only thing what is disturbing me.

Yes basically that is what they are doing, peak voltage x 0.707. But the test signals are often sine waves with duty cycle. EG when a manufacturer specs 1000Wrms@8ohms 6dB crest factor, it might be a 1KHz sine wave but with 50% duty cycle, 1ms on / 1ms off, then they take the RMS voltage of the sine wave when its on (89.4V) and calculate the 1000Wrms@8ohms power with that. RMS means Route Mean Squared, it does not mean continual power, or real heating power. |
