Sub question?

A good sub extends the treble. I've heard it all now. 🤣🤣🤣🤣🤣🤣
You clearly don’t know what a sub can do. It can add air and open up the sound stage which improves treble response even though it is a subwoofer. You are completely wrong and have no idea what you’re talking about.

It doesn't extend the treble though whatever you may think. I know what I'm talking about, I have no idea what you are talking about.

So basically you’re saying that you know more than John Hunter who’s been working with Rel Acoustics for over 30 years. I’ve actually met the guy and he came to my shop, so you’re telling me this article that I sent you about treble response and opening soundstage and adding air to the system is incorrect from John Hunter. Ok🤣🤣🤣🤣You are the stereo genius on this forum with your major contributor badge🤣🤣🤣 With your responses. I can tell you won’t even take two minutes to read the full article to learn something.

He didn't say the treble was extended he said it was improved because the sound was more balanced. Had enough now. Go and patronise someone else.
 
Here are my Sonus, Faber Extremas running them full range and using to Rel Stentor 3’s crossed over at 28 Hz to fill in the bottom low frequencies. The Rel Stentor is rated I believe 220 hz-11 hz -3 DB down in room.
That set up should be fairly good for listening to pipe organ music, although the 11 Hz Lower Frequency Response In Room at -6dB would not quite manage 64' pedal stops which go down to 8 Hz. The Studio III would be much more suitable, but still totally incapable of accurately reproducing such low frequencies.

It would be interesting to know what the lowest frequency response would be at 0dB.

I know it’s not 11 Hz obviously. I know I’m probably getting flat down to 20 but I’m not using any room correction in this room. I liked it better without. I have a Arcam SA-30 sounds fabulous in my bedroom on Tannoy Minis with a Rel T9x with correction. I took it into the music room ran measurements with the stock microphone. Which could’ve been my problem and unfortunately, the Extremas have a very low and non-linear impedance curve and the Arcam did not like it at all and got hot and shut off pretty quick. When I designed the room, I used dimensions from George Cardas. But I would’ve thought that the room is above average in sound and adding the Arcam I thought that it would be incredible because of not needing to much to correct. I did not to me. Sounded lifeless but they were voiced for beauty, and not neutrality. Not saying they’re not open a detailed they are it just didn’t work well with them could’ve been user fault as well. I didn’t pursue it too much after that. I will say the bass from the speakers and subs is the most realistic out of all the speakers I have. And I purchased these in 1994 or five. I also have a replacement drivers if ever needed. And I know the crossover’s are potted in resin, so that protects them from any heat or air exposure. Whether they have lost any sound quality I wouldn’t know. I’m probably used to it and I’m 60 years old. They do throw a hugh soundstage with incredible depth and height more than any speaker I’ve ever owned and own to this day. Sorry for the long reply😊 I love this hobby and music I don’t know what I would do without it and my dog. This group is incredible too. Sitting here listening to them right now and the blood pressure is low🤣 The thing about the WiiM Ultra something like this 20 to 30 years ago would’ve been thousands of dollars. It fits right in the system with my chord dac. Also, I’ve tried lumen, and the aurendor and the Hifi rose streamers, and they were not any better. As a matter fact, I like my digital better now than my analog rig, which is a Basis Debut with vector tonearm and vacuum with the exception of some audiophile pressings. And, my real to reel is sublime. It’s going to be really interesting to see what WiiM comes up with in the years to come. Anyway sorrry for the long reply just an old retired dude, hope all is well
 
Hi all,

Quick question..

Would it be better to connect my Sub (SF Gravis I) to my Wiim Ultra or my NAD C368?

Just thinking about this whilst conducting RC ..
I would try them and don’t do full 20 20k unless the treble is elevated that there’s brightness that annoys you. Many would try 40 to 4K try that first then listen. Do you like what you hear? If not second would be 20 to 500. In my setup 20 to 500 is most cohesive sound. After you find what you like then play around with sub latency play around between 1 to 10 switch between speaker and sub.

If you know so much why are you talking to @slartibartfast like that? There’s no reason to lecture him or us. He knows his stuff and contribute to beta that benefits all of us. Do what you believe in.
 
My best option so far... Connect the sub to the Wiim to get the bass management from the Wiim. Then connect the main speakers to my amp. This works for me. There are timing adjustments that can be made id desired.
 
+1 to subwoofers changing the perception of HF extension. It's well known in mastering world that if you want more high-highs, you have to balance them out with more low-lows, but just lifting up the very lowest octave can seem to change the perception of the highest band (even when you haven't changed anything up there).


In terms of subwoofers being driven from pre-outs vs speaker outs, it sort of depends on the group-delay characteristics of the subwoofer in question. One of the keys to a good subwoofer setup is trying to keep the sub and speakers singing as in-phase as possible while their outputs overlap. Even with a crossover, they'll largely be singing on top of each other at the same time and if the subwoofer has a different group-delay curve to the speakers (which it inevitably will), you won't have perfect blend/integration between the two. In fact, you'll actually lose some bass frequencies when the subwoofer is turned on.

In order to reduce this, your best bet is to do everything you can to keep subwoofer group delay as low as possible. Taking the feed from your power-amplifier's speaker outputs is going to include phase shift as a result of the electrical phase characteristics of your speakers, so unless your subwoofer already has very low amounts of group-delay, that phase shift it just going to stack-up and knock the subwoofer even further out of phase with the speakers.


Hopefully this makes sense?

Yes, it's all a matter of perception aka "fooling your brain". That's what we do with recorded music all the time, in particular when it comes to stereo.

Hopefully this makes sense?
I still don't see how according to that logic it would ever make sense to use the high level inputs. I also don't see how the voltage (!) at the amplifier's speaker terminals would be influenced by the speakers impedance except in amplitude, if the amp was had poor power delivery into critical loads.
