Convenience is the name of the game. Attaching the resilient channel to the ceiling is particularly challenging for one person. At a minimum you should use a solid-core door with a door-seal kit such as ASC’s DoorKit. Convenience is what drives the trend to combine one’s listening room with their film room. I then got another electrician to modify the existing floor-plug rings to accept the Shunyata AC outlets. My description of the room’s AC power a few issues ago prompted more than one reader to accuse me of elitism (“That was the most elitist bunch of crap I’ve ever read. In order to get the full benefit of a two-channel high fidelity audio system, it must be located in an environment that is customized to it, not the opposite. The walls and ceiling are turned into giant diaphragmatic bass absorbers. This entry was posted on Friday, September 26th, 2014  Authored By: Robert Entenmann. The channel’s springiness “floats” the drywall on the channel, reducing the energy transmitted from drywall motion to the framed walls and ceiling. Acoustic supply houses sell gypsum board composed of two layers of gypsum separated by a viscoelastic polymer (SoundBreak XP from National Gypsum, for example) that blocks more sound than does conventional drywall. Before telling you about the room’s design and construction, I’d like to state that a dedicated room is most certainly not a prerequisite to musical enjoyment. The walls adjoining the hallway and garage are framed 2×6. So why invest in a dedicated sound room? Your email address will not be published. The wall inside the listening room should be treated very differently from the wall outside the listening room, as we’ll see. Elitism actually has nothing to do with it. One of the problems of frame construction is that bass energy from inside the listening room puts the wooden-frame-and-drywall structure into motion—a bass impact, for example, makes the wall move. It involved screwing and gluing, rather than nailing, the wall structure together. You can follow any responses to this entry through the RSS 2.0 feed. I could hear fine detail in the lowermost octaves. The size, i.e. The speaker had a spooky sense of realism, with instruments appearing seemingly out of nowhere with startling immediacy. Some integrators utilize custom tablets, enabling the user control of every function of their environment from a handheld device. Begin typing your search above and press return to search. Fortunately, acoustic-design consultant John Brant has created an excellent tool on his website (jhbrandt.net) for evaluating room dimensions. Furthermore, most home theater rooms are acoustically treated for their primary purpose, film! I know several audiophiles who have built expensive dedicated rooms that sounded awful. 1). Replacing your AC outlets is a relatively inexpensive upgrade (see Neil Gader’s review of the Furutech GTX-DR NCF AC outlets in Issue 291). I spent the next eight weeks listening to the system powered by the stock outlets. Between the stud dampers, the damping rectangles between the resilient channel and the studs, the damping material on the channel, and the damping between the layers of sheetrock, there are several hundred pounds of ASC WallDamp viscoelastic material built into the room. The majority of home theaters are completely over deadened (far in excess of 20%), and for good reason: movies have very intense bursts of low and high frequencies, such as explosions, propagating contemporaneously into the theater. Make sure your integrator consults with a professional two-channel applications architect who can offer their services to ensure that your investment in home entertainment is well executed. To avoid damage to the new house (and preserve domestic tranquility), the listening room has a secondary door that opens to a third-car garage with no step. Most reputable integrators are capable of providing an outstanding home theater experience; however if you want a zero compromise approach, then we highly suggest consulting with NYC’s premier two-channel architect, HFDG. Utilizing floor standers could solve the problem, however in most seven or nine channel systems, this is not a tenable option either aesthetically or functionally. Constrained-layer damping is widely used in many industries and is a science unto itself. After evaluating the possible construction techniques for my room I chose one that simultaneously solves all three of these problems. Stephen was a prodigious musical talent (he went on to get a degree in Composition) who generously shared his records and passion for music with his little brother. I cannot stress enough that two-channel applications require an entirely different and specialized skillset than that of home theater. Although I was disappointed at the time, the situation turned into a valuable learning experience. 8 shows my room with the channels installed. When you think of the extraordinary effort that some loudspeaker designers put into creating inert and well-damped speaker enclosures, it makes sense that one would want similar performance from the structure in which the loudspeaker is operating. To see how I chose the listening position and speaker placement, check out our room and speaker layout guide.
