To run Audyssey you need all your speakers plugged in. You also need to plug in the Audyssey microphone into your AVR. Then just follow the instructions.

Audyssey is not the perfect cure. It helps but it cannot solve all your room's acoustical problems. So, yes there is still use for those room treatments.

An example of a graph with and without Audyssey.

The 1st one is without Audyssey



The 2nd one, no change in anything except engaging Audyssey.



The graph without Audyssey has a sharp peak at abt 32Hz. There are also 2 dips at 50Hz and 70Hz.

With Audyssey, the peak at 32Hz is smoothened. The dips at 50, 70Hz are now less pronounced.

The 200Hz dip is seen without Audyssey and it is quite big. Whereas with Audyssey it is better.

Here's my graph for before and after Audyssey:

Looks nice. If you get an eq and tune down few dbs from 32 to 64hz then that would be much smoother. Looks like this sub is a good buy.

audisi multiEQ XT memang sedap ..love to see those sifus here tame down the peak n drop

u guys really hardworking to prepare the data plot

The F15 does come with a parametric EQ, but one band only so I have to choose which peak to tame. To do more, like you said I'd need an external EQ. But dang, one of those is like the price of a sub! Or an XPA-5

Part of learning about this hobby. Really, before I was also dizzy about all this stuff. Slowly as I try some of these things out I learn to appreciate it.

Hz by Hz plotting :



This evening, I did some treament again. I loaded 2pcs of 2" foams into the back of the room. Done clapping test and some freq test.

Anyway, I will do some treatment on the stands first. I mean the 2 pairs of surr stands by filling it with sands / pebbles. Will make it near solid. Then, apply small foams on the downlight to stop any vibrations. The back wall will be tested with RPG diffusers. Have to look for big bean bags.

Next, it is abt shifting the DVD racks. Then, will do a FR check again.

I did exactly the same for all my speakers
I thought need to do a separate run just for the sub? No?

btw, after running the Audyssey there's improvement on the sub
it's just that i know nothing about graph plotting, and frequency kinda things

I did bought the SPL meter, but even with the SPL meter I still feel that nothing beats our ear when it comes to the final output. We could get the SPL meter to show all the speakers at the same sound level but in the end if we feel that it still does not give us the punch we wanted, then still need to calibrate with our ears.

The other thing i won't want to do is acoustic treatment for my room. getting the room treated usually requires placement of silly looking things which I cannot compromise for my living room. And moving my sub around to odd places is out of the question too. To me , i am not after the best sound but sound that is appealing to me is ok oledi.

If that's the case, you need to buy SVS AS-EQ1 or something similar to this

Anyone know how much is this?

Looking for 4 pieces. If expensive, maybe get one and ask the carpenter to duplicate the design.

This is poor man sub eq. Note that it is not as advanced as SVS AS-EQ1 as it can't correct phase or time-domain issue. Only can help to tame those peak. I wouldn't advice on boosting the valley too much as this would limit your sub headroom.

pierreye,

Since it is wood, I think it should exceeds RM500 mark easily.

This RPG diffuser already abt RM300 (IIRC, it's a pair) Made from styrofoam.

You can now have use Acoustic Resonator to treat your room now. No more traditional room treatment stuff anymore. CMY is the sole distributor now. It's amazing if you attended Frank Tchang's presentation during KLIAV.

dont know stick some mahjong on the wall can work or not

ROTFLOL.... Darn funny.

I will do 2nd treatment today. Shall see how it goes.

nadky, any link / info on that? TIA

htkaki, here u go..

I had seen the styrofoam but didn't pull the trigger cause styrofoam might not be a good material to diffuse sound. The styrofoam might not be good for lower freq. But maybe I'm wrong, any data or test that show styrofoam is as good as wood?

tks, nadky.

pierreye, here's the co link :

I think that wood is better too (One of the reason why my billy bookshelf is at th back of my listening positioning with lots of books and mags.)

I seriously need bass traps.

oki doki

WOW!!!!

Btw, I just got 2 huge pieces of sort of 'rubberised at 1 side' foam. Nearly an inch thick. More on that later once I get it done in my room.
