Since many of us have been doing the FR graph and even waterfall chart, it is better for us to share it here .

Also, please share ways / ideas in taming the graph.

Pls also specify the room dimension, any acoustic treatment, etc (if possible)


Mine :

Room size : 10' x 20' (bad room size)
Minimal acoustic treatment with absorption panels and book shelf at the back as diffusor. No bass traps.

what's the red and black line (before /after?)

Bro, how come there's a dip at the 48hz range? I believe svs eq1 can help even this out? Maybe you can post a graph pre and post audyssey MultiEQ (using ur denon) and pre and post SVS eq1.

If its not too time consuming Then it will give us laymen a better idea of the true power of ur beast

taiko, when ordering one?

Me no taikor la, young peasant onli hehehe...

Will order when my old one go out then new 1 come in haha...

yeah, old one dun go how new one can come (cantonese saying) hehe!

KNN this saying cannt be applied for HT or else forever be poor man leh haha

Here's the AS-EQ1 :

Impressive... is this the graph of your sub??

Also i am wondering if this is just before and after calibrating usign SVS eq1? No other calibration done? If yes, this gadget is working magic..

Jz done the AS-EQ1. I have yet to use 4310 to run Audyysey, which is recommended by most of the avs forummers.

Yes, it is indeed impressive. Here's the review :

Thanks! Pls share with us the graph after u run with audyssey (Denon)... I'm still a bit skeptical to run audyssey on my onkyo

I posted this comparison sometime ago but was missed by many; so, I'll just re-post here for posterity

FR graph using REW to demonstrate the effect of my DIY corner bass trap.

1. All bass traps in place.


2. Remove Front Right corner bass trap.

Why are you skeptical? Got bad result before?

Set my fronts to -5 and set my sub to -15 ><

You only should be concerned if the setting is at the extreme ends (plus or minus).

In your case fronts at -5 dB is normal. Mine is at -7 dB. However, for your sub at -15 dB is at the extreme end. This indicates some kind of set up issue - simplest thing to try is decrease the volume control on the sub and rerun Audyssey.

Sub volume was at 25... Now i have set my sub reference level vol at 20-24... No prob at all.. I might give it another try and see as its quite time consuming and i spend more time calibrating it back to the way i like the sound to be....

When u rerun Audyssey just use the minimum 3 positions (to save time). This is just to see if it sets the sub trim higher than -15 dB.

OK will try it out during this weekend Pray pray that it doesnt screw it up again...

Actually this is the 2nd time that a Velo owner says that Audyssey sets the trims too low. I suspect its got something to do with the EQ that the Velo applies. I would need to spend some time to investigate this.

Appreciate that bro... 1 reason i suspect this could be bcos of the echo in the room causing audyssey to lower my velo trim to d max..
