Great article on where to place your sub-woofer:-

I am using Fig2 placement.........except the front left sub is about 1' from wall, right back sub is about 1' on each side in a corner. Measuring output from both sub need spl meter so that sub vol output is about the same due to using different sub & sitting position. 

Dont need subdude, buy the AS EQ 1 la, one off solution. Dont need bass trap and whatever.

HTkaki came over my pad yday and help me calibrate my set with the inclusion of my new baby, the AS EQ 1..

Previously i was very sceptical that such product can work magic on the bass as i experienced very loose, muddy and boomy bass.. After setting up the As EQ 1, listening to bass was a different thing.. Tight, solid and clean bass..

As what both Ron and Htkaki say, after flicking the switch on and off a few times, i'm pretty sure my AS EQ 1's switch will be left 'on' AFAIK... Downside is, i'm still trying to adapt to certain scenes where the bass suddenly doesnt have the loud effect anymore (visible in transformers scene, the first scene "helicopter scene" and the airport "explosion scene")... Not boomy, and clean bass but stg's missing and that will be because of the near flat graph i assume..

Another thing to notice is that, after calibrating my set using the SPL meter, all my speakers (LCR, Surr & sub) trim were set to -9db ... Even setting to -12db trim on my AVR but still couldnt achieeve the 75db reference level on the SPL meter.. Probably HTkaki can shed some light on this and the solution..

But nevertheless, i think this AS EQ-1 has solved most of my bass problems

That's most ppl will find it to be somewhat less oomph as there isn't any peak or 'artificial' bass anymore.

However, still need to get down to the dB issue. I suspect it could be due to the limited room size for the monstrous setup. Even trim to the lowest, still reading a crazy >80dB. Another headache is the 'ext in' on 876 unlike the easiness in Yamaha, Marantz and Denon.

Nvm, I'll seek help from HQ and we shall see to it soon  I bet it should sounds much better when we get it done properly

the 876 mic can be used with 875 receiver or not?

I dont know, really. Initially i thought it was normal since the Dali had 2 tweeters in it...

Until bro htkaki came yday and told me its not normal... Anyone using Dali Ikon On Wall could perhaps share their experience?

Lol.. My neighbours would think that tsunami has hit PJ

Thats damn weird.. So i guess this means my driver is faulty?

Pink noise, not a problem. When you run audyssey setup , the sound occurs. It still have the 'booob booob .... booobb..' with an addition of that.

I knew you gonna get these... anyway head to AVS to get the weighting adjustments for RS SPL.. low frequency need to adjust the weighting..

look at all his cheese?! 

The reason why I set my sub vol at 50% is that as the output of the sub is dependent on LFE input, that will not be any 'distortion' if the LFE input signal is too large as some movie do have very large LFE output. Ehhhh! Can understand what I meant kar?

Ok it is like this.........LFE input very large so by right ur sub output will be large but it can't output that very that much as it is being restrict by the vol control ( eg at 30% ). So that is why I set my sub vol at 50% & let my avr control the LFE signal.

BTW auddsey set is being done but it can control the LFE output so that it 'balance' with the rest of my 7.2 system. Also even though it is at -15db ( two set up with diff sub vol at 40% & 50% ), the auddsey set the LFE out put differently.

Ummm.... I think I understand what you're trying to say. 

Well, Audyssey will compensate for your sub volume. If you set your sub volume very high, then Audyssey sub trim will be set very low (-15 dB is lowest). Conversely, if sub volume very low then Audyssey will boost the sub trim (up to +12 dB max I think). So really it doesn't matter what is your sub volume as long as you don't reach the limits of Audyssey because then you go beyond the ability of Audyssey to compensate.

What you said: "Ok it is like this.........LFE input very large so by right ur sub output will be large but it can't output that very that much as it is being restrict by the vol control ( eg at 30% )" I don't think is correct. The sub vol control is a gain control, i.e. it multiplies the input signal from the AVR. So if you set at 30%, Audyssey will boost the signal (to compensate) so 30% x boosted signal = 50% x lower signal. Like I said earlier Audyssey will compensate so that some balance is achieved.
