    Acoustic Project with 802D and Classé

    I've always believed that room acoustics is the main contributor to the overall sonic experience one has over its audio room.

    After a few experiences with my setup in my room (where I basically tested and measured my speakers at any place available) and a listening session a few days later of the same setup over a studio, I concluded that, even though I was quite happy with my system's performance, to improve it significantly, I had to go other way than upgrading my equipment.

    I contacted an audio designer and acoustic consultant (www.audiodesigner.eu). He has been involved in many important projects and I was eager ho hear his opinion. He came by and measured my room's acoustics. We talked a bit about my possibilities (it is a living room, so no 'studio like' work is possible) and decided what to do. We went for a Helmholtz ressonator at the systems wall.

    It took a few days for him to define the project and one day (from 09h up to 23h) to build it.
    The results are simply amazing and I can't put it into words the differences I hear now. My bass's performance is so much more resolved and detailed, unveiling details at the mid's and highs I never knew were there. I can clearly follow all the notes of the bass guitar with fast decay that enables the overall experience to be much more engaging. Drums are... oh dear... 8)

    The WAF is quite good too (at least mine) who loved the overall looks, so, points gained ther also .

    Here are some pictures of all the work involved and the final result. If you can do something like this, please do. You will not regret it!

        Looks nice. It is amazing how much dealing with room modes can help

          Yup, just one. Ideally, we could go even further, but the next best thing would be the wall behind me and I just don't have the space for that. The results are already amazing and I can't even start to imagine how it would sound if I could do the whole room 8O . I might do something else to turn down the RT60 for the mid's and highs but I don't know if it is justified.

            That was my first thoughts but in reality it's much more than that. Diminishing the reverb time for most low frequencies has dramatic impact on sound reproduction. To be honest, I wasn't expecting that much :P .

                Hi Maverick,

                I am thinking of doing something similar. Can you tell me what kind of material wood / plate finish is used? Is it MDF kind of stuff? I also see there is some space between the plates. Doesn't the insulating material cause dust in the room?

                Thanks,
                Louis

                  Also interested in what the panels are made of and how they attached to the wall batons, i.e. are they floating panels or firmly attahced...?

                    Very nice, so basically fiber glass with wood paneling, I asume it is special paneling that absorbe the Bass?

                    I am in the US so I am not sure I could find the material?

                      The wood is called "faia" (I don't know what that translates in to). The space between the plates is (as other factors) defined by the room's resonances. Before defining the plate sizes and depht, Audiodesigner came by a couple of times to measure the system/room's acoustic response.

                      No dust whtasoever until now. :T

                        The vertical wood bars are attached to the wall with iron L shaped parts. The panels are glued to these bars.

                          It's mineral wool and the panel is basically a bass trap, configured accordingly with the room acoustic response.

                          Sorry all for the late replys :roll:
