Anyway you sent something to measure.☺️ You did a lot for the audio community. Thank you ☺️

So you sent A1h. I personally thank you too man We need more people like you in this world ❤️

And we will be happier if you can test the Cinema 30 too. Many people are trying to chose between A1h and Cinema 30. Thank you man ❤️

You are the savior of audio community man. Really, God bless you inshAllah ❤️❤️❤️

@amirm ’s standard avr measurements is enough for me.

I saw Av 10. But debates are about Cinema 30 and A1h. I will be happy to see their measurements and all subjective opinions will be muted ☺️

I can send email. (Actually I will send it today, no need to postpone :) If many of us will send an email, I think they may send. And I can also send money for buying it. But I think that many people prefer sending email or signing petition instead of paying money. I mean absolutely there are...

There are so much interest in these AVRs, but there are only subjective reviews. There are so many discussions going on without knowing the measurements. and you are our only hope to solve this ☺️

Can you please review Cinema 30 or Denon A1h? There is no measurements or Denon or Marantz flagship avr in internet. Nowhere! And I think you are the only one who can make this review happen

I see that you already know everything you need. You don’t need information, you need advices, choices My advice is pair R3 with a very low THD sealed sub, something like Perlisten D212(215) or D15 or R212, then you will have better results than towers.

It’s obvious, but he is using a sub and I think he is considering these speakers especially for HT use. If he is not a stereo purist, he doesn’t need big towers. I am well aware of having big towers even if you use 80-100hz crossover, but price difference between towers and bookshelves for this...

Why are you worried if you use a sub and send all Signals below let’s say 80hz to sub ☺️

Thank you very much. These are vry valuable informations. And I will be happy to if you open an educational thread for electrical power required from basic physics. Where can I find full version of this Linkwitz's study?

So using an active speaker with a dedicated separate amps for tweeters and woofers works much better then a passive speaker + power amp(feeding tweeters and woofers simultaneously) combo. ? (Amps have same power)

Can you give a concrete example with a real speaker/subwoofer? For instance, At 20hz for 100db/1mt

It's really interesting that nobody couldn't invent a general formula which can be apllied to all!

Thank you Chris. But you dont need to add "room sound" to calculation. Absolutely you cant do it, since everybody has diffirent rooms. What we are searching is a general formula which can be apllied to all. So it should be anechoic space calculations.

Yes Chris, thank you. To my knowledge, these are the main reasons (there maybe more, which I dont know :) Now, we have to find a good mathematician to create a general formula for this :)

That's called good work..lefty man :):) Well done
