PostSubject: Want the advice from Michael and members   Mon Oct 10, 2016 5:49 am

Greeting from Thailand, I' a newbie here.
I can share some image here then please feel free to comment and advise me how to improve it.
My room is so small 3.5x4.5 meter 2.55 as height, I already have some acoustic treatment board that resulting improved the unwanted bass extension and resonance, but I still heard the unwanted mid-low frequency that still standing there, I think the 4 ceiling corners need to have a treatment, and also the the little pillar part might cause this unwanted reflection, can you please advise how to improve this, below is some image.

Hi Thanaporn! Welcome to the Tune Very Happy

Nice compact room you have there. Actually your room is not that small. Michael built a wooden room within a room for Tunee Bill333, its smaller than yur room dimensions.

Some questions to get us started:

a.Your floor looks like tile over concrete and the ceiling a drop ceiling (is Sonic right?), what is the materials the walls?

b.What's the equipment you are listening to? Preferred formats?

c. Looking out your window, you are in an apartment on the upper floors?

d. What is right, what do you like about the sound in your room? Is the unwanted mid-low frequency problem in the bass the only major problem?

e. What is your favourite music and albums?

Thanks Sonic for your reply

Please see my answers:

a. It is a tile floor over concrete, this is a room in the first floor, so there is the room above, ceiling is flatten and the wall material is light-weight brick.

ิb. Speaker is Proac response 2.5 drived by my owned design 600W/ch amp, the sources are CD player and almost of the time DAC plays streaming music(Tidal) and hi-resolution files.

c. This room is first floor in my house.

d. I liked almost kinds of music except heavy rock. I love percussion, test tracks, vocal, pop and most of audiophile tracks.

Actually deep bass also issue, since this speaker products low as 25hz, bass and mid-low standing wave overlay the mid and high then I could not hear mid and high clearly.

5 of front diffusers help so much, but still not enough for me now.

Hi Thanaporn

Welcome to TuneLand! I'll take a look at the system and posting later today. The pictures help to see your sound and as well the good description. The more you share the more we can get an idea of your goals.

Hope you make TuneLand one of your audio homes.

See you in a few hours Smile

Hello again Thanaporn

Take a look at the PZC's and Sound Shutters.

Here's a look at Hiend001's system.

Hi Michael,
What difference between Pressure Zone Controllers and RoomTune set, which one is better and how much of it cost for each of them please?

Hi Thanaporn

While you wait for Michael's reply and consider which products you want, here are some things to try at no cost. The results you hear will help you, Michael and the rest of us Tunees understand your room.

You will have seen that most Tunees have our speakers placed in the near field and with little or no toe-in. Give this a try: move your speakers forward a bit (about 1 foot), a little closer to each other (maybe 3 inches per side), with just a bit of toe-in or no toe-in. See how you like the sound, in what way does it change?

Are those diffusors from any of the manufacturers like RPG? Michael wrote a very good analysis of diffusors and traps on my present thread about Computer Audio. Have you seen it?

Another idea to try is to put some device at the point of the first reflection floor bounce from your woofers. Forget about the first reflections off the side walls -- that is a myth -- but the first bounce of the woofer off the floor does create a deep notch in the bass response which is measurable. Sit in your listening chair, place a mirror on the floor, find the first reflection and take a pair of those triangular cushions which you have in Thailand and put one each at the reflection points. One audiophile I know did this and it improved the bass of his Spendors a lot.

However, when you get more into the Tune like the rest of us, your speakers may be moved forward to the point you will not need this first floor bounce reflection treatment any more.

Hi Thanaporn

The RoomTune pillow product is a barricade treatment that is mostly used to deflate the pressure buildup in the room while leaving the tonal balance intact. RoomTune will allow you to balance out the response of the room. Nice thing about the RT pillows is the flexibility of placement. No matter how I treat a room (even with others' products) RT pillows is a big help in the fine tuning process.

here's a link to the basics

http://tuneland.techno-zone.net/t57-roomtune-acoustical-treatment

You should also look at the RT Squares.

http://tuneland.techno-zone.net/t25-roomtune-squares

The PZC (pressure zone controller) will take you to the next level of control by introducing variable mechanics to your tuning. I'll let you work with Harold on pricing, but when I get back from my appointment tonight I'll get into your sound a little more if you want.







When we listen to sound in our rooms we are listening to air pressure. Sound waves are not traveling in a straight line to our ears. There are 2 main parts to what the sound pressure (build up) is doing. One, pressure zones, the other, laminar flow.



This constant build up of energy is in every room and is what you hear. As the pressure forms it makes pressure zones that you can easily listen to as you walk around the room talking or making sound. Some areas are at a plus signal and some at a minus.



Pressure Zone Controlling is what we have named taking control of a zone in the room and telling it what to sound like with the use of our acoustical/mechanical tuning tools. Below we are controlling the zone with PZCs and Sound Shutters.



PZCs take the acoustical energy brought to them by the laminar flow or from a pressure zone and converts it to mechanical energy, (which makes it tunable) and reintroduces it back into the air.




The brass tuning bolts are where the PZCs are adjusted and the effects are huge. Tuning pressure zones are the last sound adjustments made in the audio chain and are the biggest as far as the size of signal (sound waves) in the chain.




Below is a typical placement diagram for PZCs in a audio room setting. There are 2 PZCFS opposite the chair and the rest are mini controllers.

Hi Michael,
Thanks to the great explanations,

So now what I can realize is the PZC is an improvement of the earlier RT pillows am I right?

I'm considered from the material point of view, the RT material is a working of energy absorbing and PZC that is wooden plate do diffuse(control the reflection), please correct me if I am not understand correctly.

I saw the stated frequency response of RT(16 to 20KHZ), how about for PZC?

I'm also thinking about below PZC component, please PM or let me know what you can do the pricing of below for my major improvement.

4 x PZC-MCC
4 x PZC-MEC

For ceiling tuning, can you please explain what are difference between PZC-CC and SoundShutter?

Thanks,
Thanaporn
