NR929 vs X4000

The X4000 can set different distance and sound level trims for its two subwoofer outputs. The NR929 can't.


Edited to add: the DSP has "dual mono" mode, which processes each speaker channel completely separately from the other, so you can take full advantage of the X4000's dual subwoofer outputs.


Audyssey and external DSPs can work fine together. You just have to decide if you want to use the DSP to process the audio before or after Audyssey does.


If you calibrate the DSP before Audyssey, the DSP can be used to minimize obnoxious peaks so that Audyssey otherwise would struggle with. If you calibrate the DSP after Audyssey, it might be able to fill in the peaks and valleys that Audyssey leaves behind.


Of course, you'll need an external spectrum analyzer to find out which procedure works best in your acoustic environment, perhaps either OmniMic or REW.

To anyone who may come to read this thread in the future, I just figured I would leave an honorable mention for my own ONKYO TX-NR929. I have had it for 7 years now and never had a single problem with it, and I use it every single day. It is connected to my Hisense 65U7G Quantum LED 4K 120hz UHD television via ARC and handles the audio for EVERYTHING I do with my home theater system, whether it's just watching the news, checking out the latest 4K UHD Blu Ray movies, or handling the audio during gaming sessions on my XBOX Series X (which is my favorite of all its kick ass uses). It has been the best AVR I have ever owned by far, and until it finally does go (which I hope doesn't occur any time soon), I will not be upgrading or purchasing anything new. I purchased this receiver all those years ago now, with a Revel Concerta Speaker System (2xF12s, 1-C12, and 2xS12s) and eventually added 2 Polk Audio PSW10 Powered Subwoofers and 4 Acoustic Audio Bookshelf Mountable Satellites to fill in the gaps and create a full 11.2 system, and I have yet to go to any individual's abode where the home theater experience can even come close to my own. It has been a system I have been truly proud to own, and it has done EVERYTHING I have ever asked it to do, and more. And all those Onkyo HDMI board problems that I hear people talk about in the forums... Well, I can't speak for any other model obviously, but I have a sneaking suspicion that Onkyo had a few models with some board problems years back (out of the endless array of models they have always had on offer, it was most likely 3 or 4 of their more budget-friendly options which exhibited these issues, and ALL of Onkyo caught hell for it and got a bad wrap. I stand by this company to this day, and if I were to have to go purchase a new AVR tomorrow, an Onkyo is what I would go with, because why would I switch up the formula, when, from the time I was given my first AVR by my father as a 16 year old kid, they have all 4 of them been Onkyo, and never did I have a problem, not ONE single problem out of ANY of them, in less than 10 years. They each lasted more than a decade, and only one of them I replaced due to an actual failure which caused me to HAVE to find something new. So anyone who wants to try and tell me that Onkyo is a bad brand, well, it'll all fall on deaf ears if your telling it to me. I know what good gear is because I've been fortunate enough to own it myself, and Onkyo is, always has been, and always will be, a HUGE part of this. q
