Why such secrecy for supplier info on a door? Surely others will also want to know without having to PM individually :D

I have a pile of stuff that pushes out squiggly waveforms from smaller squiggly waveforms that sometimes come from 1's and 0's.
It's wonderful to behold as long as you don't let the magic smoke out.

Life is short! Enjoy the music while it plays, when it stops, there might be a chair for you...or  maybe not.

actually nothing secret, just not sure if posting other's information all over the web without consent will violate any data protection act etc. Just being cautious

Im sure they would be happy for the business lead...just post their website free to all to use :D

I don’t think they have a website even, one Uncle Wenson, but he is very experienced, had got good understanding of acoustics as well

https://www.sgpbusiness.com/company/Jnw-Reno-Building-Services-Pte-Ltd

Office is at Bukit Batok

Price also very reasonable compared to many out there

Can try approach him. Busy man, gotta be patient for anyone keen

Some reading for SMT Diffusors

http://diffusor.com/PDF/170515_Resolution_Mag.PDF

And some feedback from musicians around the world, taken from SMT page. It’s really that good...

World famous Tuulikki Bartosik found its long-awaited reference Forest acoustics in a small game changing Wing  bubble in Stockholm !!

"For the first time in my life, I heard the harmonics in my instrument and by hearing them I could bring them into my music making.

When I play on my instrument I always sit and try to shape the sound.
But when I sit in the wing room, everything falls into place. I connect with my instrument and my inner self when my soul is in contact with what is around.

Now I completely relax and stop looking for my sound, because it is so clear that I now have access to the full capacity of my self and my instrument, because I now hear just about every detail, just as if I were in the forest.

Except in this studio, this level of detail I have only experienced in my forest in southern Estonia”

Here is a very good video on why this $200k system didn’t “satisfy” its owner

<a href="http://www.youtube.com/v/B-VHFamIZBc&fs=1" target="_blank" class="new_win">http://www.youtube.com/v/B-VHFamIZBc&fs=1</a>

That’s why experience is important and a good acoustician will tell u that

In the advice above, he advocates front back diffusion and sides first reflection with absorption, then two specific diffusor exactly beside MLP , near the surround speakers

At the end of my journey, I noticed these really brought up the system up to the next level. If u r planning your new HT with acoustics, I’d suggest this

1. Measure your subwoofers before u even move in, use room simulation and find that best MLP, sub placement is the most difficult
2. Once u have that, first thing target all corners or trihedral sections, place good bass trap panels, (dihedral Mount)
3. Ideally your MLP is 2/3 from back wall. Go full diffusion behind MLP ( this is very critical, it brought up a whole lot of difference). If the seats are near, then no choice, absorption
4. If u go with diffusion, SMTs are TOP class, no joke, use all SMTs, don’t mix rojak. It’s not ex, but the shipping is and cumbersome no local dealers
5. On the side walls, diffusion again, single piece as recommended. Just beside MLP. An effective one like the smt really brings the system to another level. The other day I was listening to stereo, and I was shocked to hear the sound extends all the way to the left right of MLP , thanks mainly to the SMTs, they are solid
6. Front wall I went with bass traps, there were pros and cons here. Previously with SMTs at front wall, the width was better. But bass was less controlled. And now the reverse , bass better control, but lesser width.
7. Ceiling, hybrid approach. With bass traps above with air GAP to ceiling, and beneath surface of it diffusion. Why I chose this? Firstly, not to disturb neighbours upstairs. Secondly for Atmos, we need diffusion. With the BAD panels at ceiling, the sound stage extends all the way up (height). There are two clear layers, ground and heights, Very syok !
8. On the first reflection points for mains, absorption, this is placed at the angle of incidence

There u go, that’s the very basic for HT. Take this basic approach, and I’ll assure u the system will be up at least by 50-60-% improvement , best if u can get acoustic Consultants, if cash not an issue

This 200k room is using all the SMT diffuser and bass trap now.😅

Some of it does look like the SMTs, especially the veritune V4






Are those PRDs from SMT? Haven’t seen such design

Those call golden horn, it is earlier SMT design

I see. I suspect too many diffusion stuff at his place. Can see from the pics

For front wall, I think bass traps absorption is good, same for first reflection points at the left and right speaker area

Ceiling would be good if he went for the golden horn, because I believe redirection or sound re-direction overhead sounds nicer

For surrounds at 90degrees definitely go with diffusion, same behind MLP. Definitely diffusion, the whole back wall disappears with diffusion at the back

I think he should have used a better product like the SMT Wings, that’s calculated, rather than the PRDs that redistributes sound and reflection

So from the video,I’ve also learnt one thing, other than buying the product, type of product and placement will be key factors how the system sounds

Golden horn wasn’t design using Primitive Root Sequence, read that Matt believe mathematical design diffuser will cause Periodicity effect...and the diffuser arrangement in the room are in random sequence.

QRD , PRD or MLSD all are diffuser using math to calculated and design; Wings on the other hand is using small “partition” to transit and delay the sound , SMT get the idea from the sound travel through the trees in the forest in Sweden , I think might have some mathematics involve but so far he did not announce the mathematics theory behind it unlike QRD , PRD or MLSD.

https://usir.salford.ac.uk/id/eprint/26633/1/11332557.pdf

I am pretty sure the room layout was design by Matt the SMT boss himself......or at least his Distributer in US because it is full of SMT style, especially the adjustable Helmholtz cum diffuser at side wall (those are not to redirect sound like the youtube guy said) Matt like to incorporate Helmholtz absorbing design into diffuser.

My point is not to say which design is good or bad, but looking at the photo and listening to online comments sometime really difficult to imagine how the sound of the room will be.... we don’t know the reason of why the room owner don’t like the sound , who Know, maybe his preference is old nasty JBL type of sound but he choose “wrong” Rockport speaker , or maybe he get use to room with heavy bass but the room bass is too clean for him? 😁

Let sit down as watch how the new design become...😊

Is it better beside MLP instead of at first reflection point?
