*Official Thread* Anthem AVM 70 & 90 and MRX 540, 740 & 1140

Today trying to meddle with ARC paramters of the Sub curve

Before is before:

  1. I tried to add deep bass boost of +2db ( overall level curve boosted to 80db range )
  2. Change from minimum correction frequency from 15 to 80hz
  3. remain at after calibration -5db of the sub level ( I trying not to meddle with this level)

Tested some movies since, playing loud and wow balance , punch and it’s not over hanging and boomy.
Almost got it there! The fine tuning here really mattes

Below is after:

I try not to be too blunt, lol, yes, so so, but in view of the square room, simple setup, I think anthem power is not released…

Thanks for sharing. Very interesting to know why you set the high-frequency extension so high at 210Hz? Is this the original value provided by ARC after calibration or did you change it to 210Hz? I’ve heard some AVS forum members changing the minimum correction frequency to a higher value like you did from 15Hz to 80Hz to get that extra “oomph” from the subwoofers.

The reason why you think the demo session is so-so is likely due to the room itself. I haven’t go down to their showroom since I got my MRX 1140 last year. I will try to make a trip to E77 and have a listen and if Arvind is okay with it, I will also like to take a look at their ARC calibration results to see if there is anything “wrong”.

It is also common for many first time users to feel that the bass region is lacking for Anthem AVR or AVM. It takes some time for you to adjust to it especially if you have been accustomed to loud bass with high SPL. You will appreciate the sonic difference if you play some loud action packed movies with bassy notes and surrounds…chances are if you have Anthem properly tuned, you will “pick out” sounds that previously not there before.

I don’t think the showroom performance truly represent what 740 can do, else I won’t consider buying 740. went down E77 just to experience the sound signature of anthem, seems warm and not harsh, which is what I like.

Oh yah this is the original value provided by ARC after calibration. Am connecting dual same subs via minidsp Input 1 to RCA Sub out 1.

Did you ever try to lower the high frequency extension to 120hz and retain the minimum correction Fq at 15hz?

oh nope. can test it out. :slight_smile: For subwoofer distance, am not so sure what to input via the web UI. :slight_smile: How about you @desray for your subs distance :slight_smile:

Thanks and cheers.

Could you share your thought around your settings as well?
I’ve questions after looking at your settings:

As for the tilt, you chose to start at 2.5kHz however all your spkr correction freq extends up to 2kHz.
From my understanding of how these settings work, essentially the tilt freq is pointless - ie ARC does nothing to the curve beyond 2kHz as evident from the graph plots.

To be frank, I am still experimenting with the tilt setting. I am always constantly changing it to see whether I can hear any improvement. Personally, you can leave it intact if you wish if you don’t hear any difference.

For me, I can hear some distinct differences if I play around with tilt. You need to play with both the tilt starting frequency and the tilt level to “hear” some difference. The goal here is to move the target curve to be in line with speaker’s natural (roll-off) response and let ARC re-calculate. I have previosuly covered this in this thread here *Official Thread* Anthem AVM 70 & 90 and MRX 540, 740 & 1140 - #145 by desray

Can you comment a little on your experience with your current config? Are you satisfied? What is really good and what areas could be better? I noticed your Room Gain is set at very high (6dB)…is your setup in the living room? The need to crank up the room gain is the fact that you feel the LFE is lacking…

Use the same old method as I always do. It’s tedious but gets the job done. That is to use REW and play the sine tone frequency at the crossover set for the Mains. In my case is 80Hz. Previously I have Audyssey read the distance for my 3 subwoofers which have the delay computed for me. So I’ll start off with the distance which I have derived from my Audyssey setting and then use that as a baseline. Next, I will slowly play with the phase control for each pair of subwoofers and I will either add or subtract 3ft from the baseline distance and then take a summation reading with all 3 subwoofers playing at the same time. The goal is to get the response curve of the 3 subwoofers to be as flat as possible. Lastly, to add a house curve, simply add at least 3dB room gain (depending on your room mode as well) and add at least 1dB of bass boost to the modal region to get that extra rumble on your seat tactile feel.

All these manual adjustments maybe over soon when Anthem release the much anticipated auto phase (time alignment) control later this year. Hopefully next month as there are a handful Anthem dealers already have their hands on a beta ARC Genesis to play with.

Based on my understanding, you need to include 2 other parameters into consideration.
On my setup, I aim for a flat response, thus I did not put any tilt ie 0, thus the starting freq is irrelevant.
The 2 parameters that I’m talking about is the Max correction freq. and HF roll off.

From above they are set to flat and 8kHz.
The resultant effect from the ARC correction is shown below.
While I chose flat, the correction does nothing beyond 8kHz, thus does not unecessarily push the system beyong 8k and just follow the natural response.

My understanding is that playing with the tilt and level is usually to address the output at the higher freq range. One needs to consider the freq response plot against the target curve. By def the Max Corr Freq is 5k and if the correction is needed beyond this limit, it needs to be raised higher. For example in my FL plot, I raised the limit to 8K to address the spike that extend all the way to 10k.

In my setup, the high freq are pretty awesome due to the Be tweeters. However as in-walls, the bass is lacking in punch and rumble. Thus I pushed the room gain by an additional +3dB for the added thump (the original ARC result b4 tweaking is +3dB) thus total +6dB.



I have different target curves for the subs as I try to keep it below the measured response (per advise in the manual).

Overall, I’m quite pleased with the results compared to my experience with the Yamaha… the results are more predictable esp when you can see the freq plots and the many areas to tweak.

Since I made so many changes all at the same time, it is also hard to pin point what each one brought to the table ie

  • room treatment (practically a new room)
  • new speakers (different layout positions and type/quality)
  • new AV processor
  • new subs (1 sub to 3 subs)

The good - the many parameters to tweak and the ability to upload new tweaks without running the measurements again and again. The multiple profiles can let you compare different tweaks by just a click of button and swap.

The bad - the manual distance is not ideal and does not cater for sub delays (this one I am still unsure how to address manually). The remote volume - arrgh. The volume constantly blocks the subtitles.

There are more (I can feel it) but off hand I do not have time to list down more systematically and objectively like in a review.

I’ve not tried higher end processors like Lyngdorf or Storm Audio - would love to compare and see what I’m missing (or not). I’ve heard so much about Dirac and that would be nice to evaluate.

I noticed your subwoofer 2 SPL drop quite a fair bit from 40Hz and below. I guess the SPL for subwoofer 1 more than make up for it. Did you do a summation of the 2 subwoofers? What’s the combined output level?

Yes, the profile setting is a godsend feature since we can make changes on the fly and review first hand. Sometimes, I feel like I am spending more time playing with the setting rather than sitting down to watch or listen to movie and music. :stuck_out_tongue:

Yes, the OSD does get in the way of the subtitles but that’s hardly an issue since it only remain for a few seconds imo. And yes, we are all waiting for the auto phase control feature to be released in the new ARC Genesis. Hopefully by next month since some of the dealers are actually testing the beta version with this built-in feature for months. Anthem is very very slow when it comes to releasing new features. This is really very annoying at times.

Breaking news.

New ARC genesis beta 1.6.1 and a new firmware update are out! And yes, the auto phase control for multiple subwoofer finally arrived!!!

https://www.anthemarc.com/downloads/beta.php

Sub2 is actually a combine response for the 2 Focal at the back.
I believe it is due to the positioning, both are against the back wall but abt 1m from the corners.

On the RIGHT side, there’s a structural column and immediately next to it I have my equipments thus the offset.
On the LEFT side, it’s the door entrance swinging inwards, thus I need to leave 1m gap.

As the room is pretty small, the MLP is within 1m from the back wall give or take 6" to 1’ as the chair is a recliner. If you ignore the huge spike at 43Hz, the drop is not too bad. Actually due to the huge spike, the ARC kept complaining about high output during the measurement and I had to turn down the volume significantly to very low ie 3 o’clock or less.

When I’m in the mood, will try to shift the sub around,… maybe swap to the front and bring the single sub to the side… :thinking:

Wow its finally out!
