Ceiling panels installed...what have I been waiting for?!

Recommended Posts

My experience has been like many slowly moving to room treatments. Once I got stated I really liked the way they improved the sound. What I went with is RPG BAD ARC which do both absorb and diffuse - seems impossible but they do. So the next step was to do something with bass or bass traps. Personally I think they are ugly and so have avoided them. However I went to Axpona to the Synergistic Research demo of the black box. I really liked what it did and it was so small and unobtrusive. Ended up purchasing two but after experimenting returned one. They have a 30 day return policy so it was great to test then buy. I really like this device its passive - no electrical nothing to attach. You can move it in seconds to try various locations. I ended up in a corner which makes sense.

 

My next thing will be the back wall but what was suggested is what Alaric H. has pictured and to me it does not pass the aesthetic test. Probably work just fine just not for me so in the hunt for something else. Also at this point since I have electrostatic speakers and a 9' ceiling I don't think ceiling conditioning will be needed. At any rate the back wall needs to be next from what I have been told.

Hello

 

A very, very interesting thread. Thanks all for these valuable inputs (and links) when it comes to room treating.

 

I am fighting with a slightly other case: my appartment is on 3. floor. The problem is that the neighbour on 2. floor hears nothing from my music exept the bass like boom boom (depending on kind of music).

 

First of all I want to understand the matter. The appartments are very well isolated and have all the same shape. To make it simple: there are two identical boxes attached upon each other. Both will have the same resonances e.g. roommodes. I think treating the roommodes in one box cannot prevent the other box to get in resonance.

-> i have to change the frequency of resonance in one box.

 

What do you think of this approach?

 

All thougts apreciated.

@michaelD: This Black Box, what kind of thing-magic is it? Did you dismantle it and can tell us what is inside? What kind of physics is behind this box: helmholz-resonator or the like?

A very astonishing product.

I used to have exactly the same problem, I am in a level 2 apartment and the neighbours underneath me had to put up with bass from my music, even at less than normal listening levels.

 

Have a look at isolating your speakers from the floor. Barry Diament used to post a lot about isolating (floating) speakers and certain components on this forum.

 

If you have a look at the photo in post 12 in this thread, you will see my speakers are on Townshend Speaker Bars which effectively float the speakers, they move both vertically & horizontally with a push of your finger. Townshend, Diament & others who promote this methodology will tell you that it will benefit the SQ and I guess it does (subjective) but the biggest benefit for me wasn't subjective at all - it stopped my neighbour problem dead in it's tracks, they never hear my music any more.

 

The Townshend bars are ridiculously expensive, even more so now than when I got them. There are other (cheaper) ways to achieve this type of isolation so do some Google research.

 

BTW - if you have small children or large(ish) pets running around, it might not be such a good idea :)

Not sure what's in it but when you shake it there kind of a resonance feel to it. I have not opened it either. All I know it works and looks a lot better then the big old bass traps.

I used to live in an apartment and Townshend Speaker Stands fixed a similar problem for me. Kept using them after moving to a house on acres (yay ! No worries about disturbing neighbors) as I did find they improved sound quality of my system, actually a bigger upgrade than moving up the range of Focal speakers (from Electra BE to Utopia BE). Townshend products are extremely expensive... Though they are also very effective. The Speaker Stands have been the 2nd best tweak for my system (the first being power products like Balanced Power supplies and LPS).


Speaker : iPhone 6S Plus > UpTone Audio USB Regen (x2) > Benchmark DAC1 Pre > Pass Labs INT-30A > Focal Micro Utopia BE

Headphone : Auralic Aries > Auralic Gemini 2000 > Audeze LCD-X

Power & Tweaks : Heaps of Balanced & Isolation Power supplies, Dedicated Line, Vinnie Rossi MINI PURE-DC-4EVR, HD-Plex LPSU, iFi Audio DC iPurifiers, DIY Resonance/Vibration platforms using Townshend Audio Seismic Isolation Pods

I can see from the photographs that your room is quite small so the influence of wall reflections on the sound you hear is quite strong, much stronger than in huge rooms. But I can bet that this is not the ceiling sound reflection that is the strongest but the one coming from the side walls. Compare the distance from the speaker to the ceiling with the speakers-side walls distance. The photos suggest it's 40-60 cm (?). Use mirror to place the panels correctly - you should see the speakers from your listening 'hot spot' and the panels should be placed where the mirror placed on the wall is when you see each speaker. Unless you play snooker - then you won't need the mirror - imagine playing cue ball from your listening position towards each speaker after it hits the wall. The wall hitting area is the right spot for the panel :). The sound absorbing panels will work best according to my experience. They will improve overall smoothness, detail and stereo imaging beyond belief. I've made lots of sound adaptations of listening rooms and I'm pretty sure you will appreciate the changes the side panels will bring.


The man that hath no music in himself, nor is not moved with concord of sweet sounds, is fit for treasons, stratagems, and spoils. The motions of his spirit are dull as night, and his affections dark as Erebus. Let no such man be trusted. Mark the music.

                                                                          ―  William Shakespeare.
