Plus, I think all the posted results I've seen show the sub cutoff at 120. Just an observation...

It seems to me that when the sub is crossed over at a higher setting than 80hz you gain a lot more of the higher end of the bottom, but some people prefer a more bassy sound. that is why 100 is prob a good compromise.

It may simply be that there's too much Room Gain in his solution. When he posts the charts and Targets window we can see.

In your case, you have about 2dB of Room Gain which is towards the low end of the typical range.

Howdy - Just received my MRX 500, along with a set of Gallo Ref Stradas in a 3.0 setup (L, R & C), no sub for now (WAF - its an iterative process ). Room is 18x12. When running ARC, do I need to account for the lack of a sub?

Thanks!

Thanks for the quick reply!! Totally forgot about the DB9 serial cable that came in the box

Hi everyone,

just a word of caution for anyone attempting the multimedia update for the MRX series using the USB Flash Drives --- at least one of them is not recognised by the Anthem even though it is usable by everything else.

I first tried the multimedia update using a Lexar JumpDrive VE 4GB USB Drive. The Anthem failed to recognise it from either the front or the back USB inputs.

Thanks to John (jayray) who told me he used a Kingston DataTraveler 8GB USB Flash Drive and it worked like a charm. I went out and purchased one today and as soon as I loaded it into the Anthem up popped the Update option.

So, if you want an inexpensive USB Flash Drive to perform multimedia updates the Kingston works... and this model Lexar doesn't.

Hope this helps.

Cheers.

Tony

I've had my MRX-700 sitting in the box for several weeks after I moved out the old speakers and waited for the S-8-s, C-5, two Sub 12-s and surrounds to arrive. Tomorrow I set up and ARC. Following this thread as I have, we'll see how smoothly things go.

What format was the drive, FAT32 or NTFS?

If I am not going to be going the 3D route, do I need to do the multimedia update with my MRX500?

Hi everyone,

H/W the ARC 3.01 results from my MRX 500 for 5 measuring positions with my Revel Concerta speakers. I have the F12s as the Left and Right fronts, the C12 as the Center, and the M12s on their matching Revel stands as the Left and Right surrounds. My subwoofer is the PSB SubSeries 6i. The Revel speakers have an exceptionally flat frequency response and are arguably the best engineered speakers in their price range.

The listening room is setup as an L shape with four measurements taken directly in the main listening window in the front of the home theatre system and one taken on the left about three feet in front of the main sofa. Distances from the sofa center point are approximately:

Front left, right and center: 10 feet
Subwoofer: 11 feet
Surround left, right: 4 feet

I believe the asymmetrical layout is what causes the ripple effect in the ARC measurements. As you can see ARC doesn't have to work too hard given the flat frequency response up to 5kHz.

Cheers.

Just for fun, try setting the sub HPF to Flat. and see what that does to the curve at the 20 Hz range. Just do a recalculation, no need to do another measurement.

It may only recognize NTFS then. Although I have found that it is usually the other way around with most electronics. Just a guess.

It sounds great so far... That said, outside of a few demo clips, I haven't really done enough critical listening yet. Shopping is consuming all my free time these days. What I can tell you is that it already sounds better than my Denon 3808 with Audyssey.

I'm curious to see what Bob P. has to say about my two sets of calculations. I didn't have a chance to directly compare them with listening, but setting the sub cutoff to 100 sure does flatten out the response.

I noticed the sub change and to test that use Transformers at 1:56 where the transformer flips over the woman. This sweep is a good test of how smooth the LFE is from your sub. For impact, of course the pod scene in WOTW is very good for that. This is how I tuned my sub with ARC. The Flat setting should also give you some good tactile LFE if your sub can do it and from your chart it looks like you have a good one. I'm not sure what Bob would suggest but at this point there doesn't seem to be a lot you can do to improve. Usually any dip or peak under 2db. is inaudible anyway.

I may try that next time I pull out the ARC gear. The PSB Subseries 6i subwoofer has the following frequency response technical specifications:

On Axis @ 0° ±3dB 29-150Hz
Lf Cutoff -10dB 27Hz

Cheers.

The adjusted solution looks fine. You are losing a little bit of the high frequency end of LFE compared to the original solution, but there's not that much LFE up there.

Another approach to smoothing the original sub curve might be to lower Room Gain a bit. You can experiment with different values in the 2.5 to 4 dB range.

Hi Bob,

sounds really good. Very pleased with ARC and the MRX 500. Suffering a minor issue with the MRX 500 that I am working with Anthem on.

Cheers.

Hey all.
sitting back watching a little football! J-E-T-S!
Anyway I had another run this AM I remeasured the room again but this time, (as Bob suggested) I put the sub closer to the wall. I re ran and here are my posts. I do not know if it is reflected in the graphs, but I get much more punch now out of the sub. It is like a very tight and punchy sound! I was watching the Jeff Beck Blue Ray in DTS Master and the bass never sounded better! In fact the whole mix sounds so much better than what I am used to! You Actually feel more like you are at the gig with the audience!
Here are my Music graphs, PS John Mclaughlin from 1984, also sounds better than ever!

When frequencies are corrected accurately
,the result is a more 3D sound field ie. feels more like you're there. This is why ARC gets so many accolades. Reviewers comment on this time and again. Enjoy. BTW, a different sub will give you more deep LFE but that's for another day
