But there a lot of people out there who still use the old CS series and even the PV2000 amps too and say they love them still, they get them serviced and the amps are good for years more use.

Im just telling you my real world experience if you are a disco fair enough but if your on anything with demanding bass line ie DnB garage Dub etc Nah.You cant compare 1210's I have Mrk2 & Mrk5 there is quality in the build (With old amps the caps and other components start to deteriorate unless you service them cant see the economics in that)and there is a price difference.I like old amps ie nostalgia but not to play out with in this day n age too old to be carrying old iron around when something lighter with more power can do the same job stick with the QSC as with the Peavey you will need a stiff power supply ie 240@20-32A to realise its potential Peavey prob 30yr+ QSC Prob 15yrs+ old bless

You're saying the CS1000x amps are hopeless nowadays, is that you're saying? Despite people saying they may be very old but they're still excellent on subs. If yours was cutting out then it's the first one i've read anyone had problems cutting out. Sometimes old is better in some ways, look at Technics SL1210mkII turntables there's a lot out there that are 30 years old and still working.

Nah Ive owned Peavey CS1000 I had four sold the lot and went to Crest CA12/18 which were the same in weight but more power. The CS's heavy and hopeless in these modern times,I was using PD186 and they struggled to drive them cutting out n everything so I could imagine what they would be like with hungry drivers. Further more if you play by myself you might stand a chance but if you were in with another sound you would definitely break down bless

Maybe that's why the old Peacey CS1000x amps sound so good because they suffer from more distortion so if two bridged CS1000x amps sound better than one RMX4050HD in dual mono one sub per channel it might be because the RMX4050HD has lower distortion. I mean the RMX4050HD I read was tested by Abeltronics to be able to continuously deliver it's rated power.

"Two amps of exactly (or not far off) the same power output (according to specs) can sound different," Very true. A friend here swapped out his RAM BUX 5´s for Crest 8001´s and the difference was crazy - even though the RAM´s were (supposedly) far more powerful than the 8001´s. You don´t know until you try it. Then again, it might just be more distortion... |

I would suggest that you read this on power ratings for loudspeakers: https://www.doctorproaudio.com/content.php?2260-loudpeaker-power-handling&langid=1 In short, your AES rating is calculated from an RMS voltage measurement taken from driving the speaker with a 40Hz to 400Hz pink noise signal, with a 12dB crest factor. If you’re playing heavier, modern bass focused music then the speaker will approach thermal compression much sooner, due to heating. A better thing to think about is average power, and ensuring that the amplifier can deliver peaks without clipping. In practice, this means that you would likely get slightly louder peaks from using the bridged amplifier, but the long term output would remain the same. You would of course also run the risk of more easily cooking your coils, if you are not careful with limiting and running the system accordingly. It’s up to you if this is worth carrying ten tons of amplifier for. Personally, I think that would be much better served in carrying the same weight in more cabinets when more output is needed. |

Sometimes sound dudes over complicate things.
Sounds like this is more of a hobby, than source of income for you. RCF L18P300 are not thirsty drivers. Sell your 4050HDs, and get pair of 5050s, and they will sufficiently/reliably power your cabs, to get you paid for gigs. Many PA dudes who gig frequently, without large crew, would prefer E90/K20/FFA 10K. Bridging 5x tonnes of 100 year old Peavey amps, to drive 8x drivers, is just not how serious sound dudes do it, in 21st century.

The subs are each loaded with two RCF L18P300 so they can take the power in stereo they subs with the FRC drivers are rated at 2,000 watts AES and the RMX4050HD outputs 1,400 per channel into 4 ohms. Plus music is dynamic not a continuous sinewave.

Cool, but your driver definitely can’t take continuous power of the level that even the RMX4050HD is rated at so it’s much of a muchness. |

I think where the older amps are better is that they're more capable of outputting power continuously at 30 or 40hz whereas the newer amps struggle down that low unless it's a very expensive newer amp.

Think your splitting hairs there mate. the difference aint going to be mind blowing. if your really after getting the most out of your cabs why not look for two more 4050HD's? 4000w into each cab at full chat is more than you need (obviously dont run at full volume, but will give ya plenty of power + all the headroom you want. Does anyone know the going rate for rmx4050's these days? I would have put them in the 300/400 range. Only guessing mind. P.s. just seen on cs1000x pdf it outputs 1500w into 4r bridge. ---> https://assets.peavey.com/literature/manuals/80301955.pdf Not really much of a change from the 4050 in stereo.
