Apilon, I would try moving your sub around a bit. Run quick measure and try to get rid of that huge peak before it falls off. Try to get your cut off to 120 after running arc.

I am in the process of connecting 2 vintage Vandersteen 2W subs in the system which connect to the front speaker amp through parallel connection using inline high pass filters. In that case before running ARC do I configure front speakers as "full range" & sub to "no"?

Here i changed the settings to flat and also since my sub design call for a HPF at 23hz i also tried that settings


i also change the cutoff to 100 hz and it seem to be better


what do you think

The third and fourth subwoofer graph looks flatter as it approaches 20 hz.

What are the different settings? Did you manually set the cutoff to 100 hz or did ARC make it 100 hz?

I'm wondering if the crossover adjustment on
The back of the sub is turned to its highest
Value. At 60hz the response falls off a cliff.

If it is at its highest value then apilon needs to
Work on different sub placements.

Simply changing the xover to 100hz is not doing
Much good in my opinion.

I agree With grasshoppers. You should try to obtain 120hz naturally. Sometimes moving the sub even a little bit will help. Using quick measure to eliminate that hump at 60hz should do the trick. Once you find the better spot, rerun ARC and you are golden.

Arc set the cutoff for the sub at 80 hz as you can see in my first post, all other cutoff were set by arc as well

then i set the sub cutoff to 120 and 100 as you can see in my second set of message

The first image is the sub at 120hz with auto , second image is sub at 120hz flat , thirds is sub flat at 100 hz 4th is sub flat with 80hz and last is sub flat with hpf 23hz

sub is powered by behringer ep4000 with minidsp set with hpf at 23hz

i will try to move the sub a bit and see if i get better result

Arc-2

Quick question, does ARC-2 support MRX 300/500/700? From what i read, ARC-2 is superior and easier to setup.

ARC2 was designed for the x10 gen MRX receivers. Not sure if you tried to load it on an x00 MRX if it would fail to load or brick your receiver. My guess is that Anthem has it coded to check for the receiver version and fail to load.

Has anyone placed the mic 1m infront of their main speaker and taken a measurement?

I did and was expecting a slightly flatter response curve?

I guess because in quick measure there is no smoothing the graph is going to look more jagged.

Has anyone else done measurements like this?

I guess ARC can only improve things a certain amount.

Is there anything I can do to improve the curve beforehand and re-run ARC?

I've attached my initial 5 measurements
