ronildoq Posted October 18, 2018 Posted October 18, 2018 I’ve been a very satisfied and happy man, enjoying my HT system, having completed my journey 1. calibrating the subs 2. Video calibration 3. Integrating the systems using Dirac In all my approach, I always look to calibrate the system to reference, then tweak to preference. This has been my method and goal. Then one day, I stumbled upon these diffusors , SMT Wings ! This stuff is amazing, incredible ! It’s been around for some years I’m more of a HT guy, 80-20% music. I appreciate HT better, mainly because all the family get together , my kids and Mrs. So in some form, it’s family time. Sound Quality is very important to me, no compromise, especially on vocals. With good sounding crystal clear vocals watching documentary etc, the kids pick up, speaking fluent language as well. That’s a plus indeed . What I’ve experienced with The SMT S Wings unit, is an enhanced depth, clarity, timbre and details to the set up in my room. This effect is something that electronics can’t produce. It is helped with radiated energy using these diffusors within the room. So here goes again, my HT journey, to bring out the best in my hall. It’s a very challenging hall, 8x6m in length, but this time round, I’ll be working on the decay times in the upper frequencies using the help from tools to measure energy times using REW software, to identify where to best place these S Wings in my room. I’ve got in 6x 120x60cm panels, and 2x 60x60cm panels from Europe, (yet to Arrive) with an idea of where to best place them in the room. Whether or not it will be as effective, that’s where I’m going to share my journey here. My previous demo loan panel was just 2x 120x60cm panel and I could hear so much difference and quality it brought to the set up.... What does these wings do ? It’s a spacial and temporal diffusor. Imagine this, when you throw a bowling ball onto a wall, it will bounce off the wall. Similar to a sound wave. Now if u have a diffusor on the wall and throw the ball again at the wall, that ball will burst into tiny pieces and scatter, if the diffusors are working as intended. That is the traits of a spatial diffuser. Now if those exploded pieces emerges in a different time relative to one another, then we have a temporal diffusion situation, where fragments repeats itself over time, until it decays off. The s wings does this diffusion in space and time and good diffusors work this way. First I’ll share my individual speakers energy time curve, then I’ll share again what happens after I place these s Wings. For now, still waiting for the S wing to ship.... stay tuned... to be continued ... Very good stuff! Once in, not coming out.... Sent from my iPhone using Tapatalk

Amazing europe stuff there. )) Sent from my SM-N9005 using Tapatalk Haven’t really started, waiting for it to arrive , very slow, but worth the wait. I’ll wait patiently. While waiting, I’ll share some details about the current room condition, what I have in my room, how I’m going to shift them, to make way for the wings. My main application and focus will be for HT, rather than 2 channel listening. I have the Low bass taken care by psi active bass trap, 1 unit only. but still insufficient. Need 2 units to be effective. So I’ll shift some of the panels using dihedral mounting, like this.. This method above is very effective in trapping bass energy, with a air gap at the back of the panel, especially when wavelengths down lower frequencies are much longer. Since I’ve already identified the room modes, and which areas have bass ringing, I know exactly where to place them. So that’s done. See here http://www.xtremeplace.com/yabbse/index.php?topic=268900.15 1 MOAB goes this way, and 2 absorption panel, total 3 pieces on dihedral mount to trap bass energy. The 2 aural aid corner traps will remain as it is. I have carpets on a laminated timber floor. So carpets absorbs in the upper frequencies whilst the wood transmits tactile energy, further amplified with crowsons and leather material sofa. Very happy here, nothing to improve anymore. On first reflection points, very nice thick black out curtains , but only on the right side [emoji51][emoji51].... left side empty, it’s the door So let’s see the left side of the speakers reflection point, and what is the angle of incidence Long journey ahead... with all the mounting work etc...but having lotsa determination to push it through Guys, just feel free to shoot anything u want and anything that can improve, most welcome to do so!

There is cardboard version and wood version, we got in the wood version, demo stocks .... Pricing for new is below, before shipping ... But this is Super high quality stuff, 2 pieces in a 8x6m room can be felt almost full force... can’t compare to those QRD or clone versions from China, totally different league... it even works placed nearfield, so good.

desray Posted October 20, 2018 Posted October 20, 2018 Acoustic treatment is the “last mile” for any HT and your living hall is really very big certainly will benefit from some form of treatment. But Just make sure don’t over-do it. Based on my short listening experience, you need more absorption than reflection. Remember that’s your living hall we are talking about here. By the way nice diffuser designs etc. Keep those pics coming. Sent from my iPhone using Tapatalk
whitesox Posted October 20, 2018 Posted October 20, 2018 And for me... I have been searching for my ceiling? will 3D wallpaper be able to act as absorber? Do you have any information to get absorber for the ceiling?

synthesis1624705793 Posted October 20, 2018 Posted October 20, 2018 Thanks bro for this info... what is the size/panel and price? :) Focus A is 60x60x2cm. Check with them for the current price. It's not expensive considering the number of panels. You need to buy in a box. 1 box of 28pcs is probably $300+.

All the panels I have now are All absorption panels. What I’ve come to learn is that a combination of both diffusion and absorption yields a very satisfying result, the absorption is focused for lower bass area whilst the diffusion’s for surrounds , back wall and front wall. I’ve also noticed this is not just any diffusor, it works down to 250hz in the time domain. The results are amazing, a very even diffusion soundfield, and this is far superior to any of the QRD diffusors I’ve tried. I’ll share again with measurement tools, how I intend to approach this with placement and how this affects what we hear in the end. The key area I’m working on now is how And where we should place them for it to be effective, in that hall. This is the next exercise I need to go through. Then probably one final emotiva processor with Dirac , then I’m done for HT.
ronildoq Posted October 20, 2018 Author Posted October 20, 2018 And for me... I have been searching for my ceiling? will 3D wallpaper be able to act as absorber? Do you have any information to get absorber for the ceiling? Wall paper won’t do anything, don’t waste time. What most people don’t realise is “placement”, the placement is very important. Similar to your speakers, the diffusors and absorbers work in a similar way. You need to know exactly where to place the panels on the ceiling. Not just put it all over the ceiling. Think of it this way, the speakers produce direct sound. There is also a reflected sound that bounces off the floor, ceiling and side walls. The physics behind is that the angle of incidence will always equal the angle of reflection. So 1st, u must identify the reflection point. Where is that sound reflecting off, when u place the speakers at the centre of your room below the tv, example. Ideally , it will be at approximately 40-50 degrees on the ceiling and floor that needs treatment. How to verify this ? Use REW and umik 1. Measure just the centre speaker, then look at the energy time curve. Then look for the peaks Any peaks above -20db are the ones that needs attention, so place the panels at respective locations , then measure again, until the peaks are brought down. You can use the mirror or string technique for this The point here I’m trying to drive, is not how many panels or area that is covered, it’s where the panels are placed that matters.... The wings does it very well, using the reflected / radiated energy from the room. But all will go to waste, if not placed at the right place Sent from my iPhone using Tapatalk
ronildoq Posted October 20, 2018 Author Posted October 20, 2018 What is also important to note is that, placement varies. Depending on type room For HT room, there are many speakers in the room 11 speakers including Atmos, so it’s a real challenge with placement For critical listening for 2 channel, it’s different again, how we should place then wings Then for studio, it’s different again. Placement horizontal or vertical will determine how the energy radiates as well, upwards downwards / side ways left right... So many things
ronildoq Posted December 24, 2018 Author Posted December 24, 2018 SMT Wings just arrived from Europe !! 2 cartons, some of it not mine Echophon ceiling panels just arrived too, getting the hall ready for 9.4.6 or 7.4.8 Ceiling speakers ready with belden studio 814 speaker cables to be mounted: full monitor audio setup, but I love the MK300 speakers, in wall series, that one is really awesome ! NO SBIR issues Echophon panels for suspended ceiling with 60kg rockwool density, leaving 3cm air GAP in a 60x60 grid mounting system for bass traps This will be paired with 16x BAD diffuser panels flanking the Atmos speakers for wider dispersion characteristics Haven’t unboxed the SMT wings... stay tuned...previously was just 2x 120cm and I was like WOW [emoji50].. this time round will be 8x, 2 back of MLP, 2x for surrounds, 2x behind mains, two small ones flanking centre channel... The rest of the 6x MOAB panels will go for dihedral mount ceiling corners for bass trap, supported by another 2 aural aid corner bass traps and 1 psi active bass trap... Exciting times ahead... the above SMT wings will be pairing the new Lyngdorf MP-50 processor, arriving from Denmark soon, in January19 Stay tuned.... Sent from my iPhone using Tapatalk

ronildoq Posted December 24, 2018 Author Posted December 24, 2018 will share more pics soon, some of it not mine, some of the forum members tagged along..... will also share the before and after room response etc
ronildoq Posted December 26, 2018 Author Posted December 26, 2018 War zone now at home this morning Before the dismantling of Atmos Existing kitchen sliding door Changing it out to 120kg density rockwool ply door with mass loaded vinyl on the other side, rockwool surface facing hall acting as velocity trap, hopefully can see some nice bass decay times after the change, incomplete version below Laying foundation for the grid ceiling system Partially done grid system 60kg density rockwool will sit on the echophon A panels, covered, rockwool to ceiling will have 3-4cm air GAP to work as bass trap ... With this 595x595 grid system, I can switch about my atmos speakers, swap out the echophon panels for BAD panels, or put in a vicoustic diffuser panel, lotsa flexibility....mounting for ceiling will be, diffusors-absorption-diffusors, all diffusors at extreme left and right, only 2 pieces exactly 40-50 degrees from centre channel speakers left right wings. this will give me the directivity with wider dispersion and soundstage Uncle who installed for me, very experienced, he said ok, will help me install The SMT panels as well, very nice!! very cincai also, not calculative, I like Sent from my iPhone using Tapatalk
ronildoq Posted December 26, 2018 Author Posted December 26, 2018 More pics... Grid type with one of the Atmos speakers How it was mounted onto the echophon, then with the wood pieces resting on the grid system to secure it Uncle’s skills to saw the circles, skillfully done 8cm , just nice for the Atmos speaker, Swee Swee calculation... Can be moved to another area if needed,cables Long and 595x595 system gives me this flexibility Rockwool stuffed inside, you can see the air gap to ceiling, this will give me some bass trap. Uncle says no use going more than 60kg density rockwool on ceiling, no diff... Suddenly realised short of 5 panels! Alamak [emoji1751][emoji3603], luckily bro SDDS had 3 pieces to spare, Uncle will load in 2 gypsum board tomorrow... still awaiting BAD panels to arrive from China ... Journey resumes tomorrow, dihedral mount panels on ceiling for bass trap and SMT on wall... Sent from my iPhone using Tapatalk
