jjj 寫:Raymond Wan 寫:jjj 寫: Me not expert but I think the extra Real Traps did not show improvement in Raymond hing's house (although still can affect imaging on real life listening) may due to ;
1)Real traps placed on opening area(door)
--Try on front/rear right corners(enclosed area) maybe(may not) better
--I feel with existing Raymond DAADs placements, only hang all extra Real Traps on ceilings(scatter around with 45degree to corners) then able to see better improvement.
--Consumer bass traps did not design to trap low low frequency + most rooms are not big enough
2)DAADs already done a nice job
--Bring all DAADs out of the room and replace by Real Traps then can compare the both .
Through my little experience, only scatter bass traps all around the corners(including ceiling) then will see good results .
Raymond hing may also want to just open 1 of the doors slightly(to leak out some bass) and measure(just try for fun ).
I am just passing by , please do not shoot me , I beat myself first
(Note: I did not use any of Raymond hing's bass traps product and those EQ software before :sorry)
Hi Jason
Long time no see ! How's your AV life in Singapore ?
I am not just testing at the door/wall corner. But also at wall/wall corners at the front left and right.
If you have time to review all my tests on RealTraps, I did nearly all the possible combinations of using RealTraps and DAAD individually and together on both corners and walls.
試用 RealTraps 產品 --> viewtopic.php?f=7&t=155185
RealTraps 吸音板和 DAAD 調音柱測試 --> viewtopic.php?f=7&t=155928
再試 RealTraps 用作牆角 Bass Trap 低頻陷阱 --> viewtopic.php?f=7&t=157529
In all case, the findings are
(1) DAAD is slightly better than RealTraps in my home
(2) Adding additional RealTraps will not achieve improvements
(3) Use RealTraps at first reflection point at the side walls is better than present DAAD2
(4) Use RealTraps placed along the walls at scattered locations will improve the RT60 slightly
The aim of trying the RealTraps is to find possible improvement on dealing better control on the bass frequency to flatten a little bit as well as handle the existing room mode of 26Hz.
However, I cannot achieve the goal from the various tests.
Anyway, I finally find a useful adoption of RealTraps is to use in the first reflection points.
Hence, I end up with the purchase of 4 units of RealTraps BareTraps.
Hope the above can give you full picture of my past tests and some basic findings leading to the conclusion and adoption of RealTraps and DAADs for my own home environment based on the present acoustic conditions.
I am fine , thanks bro
Already slow down on AV since baby born . Now experiencing what bro Luckybeanbean been thru before.
I have read some of your testings and experiments but I feel your DAADs already done a good job on what it should so adding this Real traps on the same locations may not improve anything. (except more on changing imaging and adding pressure)
Trying on a open corners(got doors) is not a good idea since bass will sure leak out and hard to trap . It is better still to just change/open the door slightly(just like SvS sub tuning port) and feel the difference.
What I see from your pics is your ceiling corners quite bare so that should be the locations to put and test if you really want to have significant differences from current . But ofcoz need to go thru lot of hazzale just to hang up the Real Traps...
Based on your findings;
1)DAAD can be better in your case since materials used, size and placement method,amount of space occupied in your room are different. All these can result in different imaging and etc. Ofcoz you did a good job by comparing in actual situations and not just reading . Really admire
2)Like I mentioned , place the Real Traps at the ceilings think should improve more.
3)Since Real traps is bigger in size , the absorptions of first reflections area also bigger so no doubt it it yield better results
4)Again because you covered bigger area by placing the Real Traps along the walls at scattered locations so it sure improve something.
26hz I guess the only way to to change your door/open your door . No consumer traps can do that. It may only seems improving because it improve the ringing on higher frequencies that will also affect readings on lower frequencies. However , actual fact is it is not doing anything on 26hz .
If you still can remember my room , you can see I covered almost every inches of my room with somethings(although looks ugly ). This is because I strongly believe sound is 360degree(with reflections and etc) from speakers so every small inches counts . It will be worst if room is small(like me) so better covered every areas with somethings.
DAAD2 is good but we cannot ignore the fact that it is small and the area covered is smaller for first reflections.
Again,wrong infos don't beat me I apologize first

I believe you have overcome all the challenge of AV issues as you can successfully tune in great conditions in your AV room with 7 subwoofers. You are moving to the next more time consuming task on bringing up your son and enjoy another era of joyfulness.
I still learn and struggle how to do it right with my present 4 subwoofers : M&K MPS-5410 x 2 and MPS-5310 x 2.
In fact, the first attempt to consider the RealTraps product is the Tri-corners which coincide with your belief on the ceiling corners. However, I have not taken the fixing device from Eddie so I just place them on the ground corners.
I have returned all the MondoTraps and MiniTraps to Eddie but retain 2 Tri-corners with me. I will get the fixing device from Eddie and test the final go for the RealTraps.
Even with the "open door" option can solve the 26Hz room mode, I will not use it as it will affect my boss in the study room or bed room.
Having with the room mode of 26Hz is not so bad at all since the occurrence of this frequency is not high. Even it is occasionally appearing in the movie, the extra dB will act as a body massage which is quite good as well.
But just for perfection, I will try whatever way that I can able to do for possible enhancement only.
This is the main reason why I get 4 units of RealTraps BareTraps to be placed on the first reflection point at the 2 side walls as well as at the ceiling for possible improvement on sound focus.
Hopefully, in the near future, I will see you again in Singapore visiting you and the AV friends that I met during my last visit. Please send all my regards to them. If you are planning to come to HK, please give me some advance advice so that I can spare the time and stay in HK rather than travelling aboard for business.
Good luck, good health and all the best to you and your family.
