Listening room in Attic or Living room???


Before I spend 40-50 K on a high end system I want to make a space that will not present major problems from an acoustic matching point of view. I am still not decided on speakers (Vandy %A, Wilson WP & or Ariel 20T) The width of the living room is 13 feet 10 inches wide from base board to baseboard, about 35 feet long combining the dining room and living room and 9ft ceilings. This is new construction (thin sheetrock) but solid oak floor and a thick carpet (area rugs).

I could possibly put the speakers at the other end of the living room which is the entrance to the dining room, just in front of the two columns. This would minimize the open side wall on the other end but now how can I position the electronics to still allow an uncluttered walk through between the dining and living rooms. I suppose the CD and preamp could be to the side but how can the power amp or monoblocks be to the side? I know the speaker cables need to be the same length etc. I first thought about creating a shelf between the ceiling and the beam separating the two rooms but I don't know about heat buildup. The speaker cables would also need to be longer runs to come the 8 feet or so extra down to the floor level (just a crazy idea). I really don't want to partition off the two rooms (have to divorce wife).

As things stand, it is a long room. The speakers if positioned 7 feet apart would only be off the side walls by two feet. Is this enough? Please let me know what your thoughts are.

The second option is to finish the attic space (now no heat and a plywood floor) but opens to the second level of the house over the garage. I could build in acoustic treatment from the start but I don't know about the dimensions. The shape of the ceiling en face is trapazoidal. The ceiling height at the level of the horizontal rafters is 7 feet finished but this spans only 6 feet across. The beams then slope downward from there to one foot off the floor. The useable floor dimensions would be about 15 feet by 15 feet since the side walls slope downward from the 6 foot wide flat part of central ceiling. The actual plywood floor dimensions are 19 feet by 19 feet giving the room a big feel at the listening height. I don't know how such a relatively small cubic foot space would sound acoustically with the sloping side walls and reflections. With acoustic treatment perhaps this could be controlled. Any thoughts? I can email pictures of the space if it would help. Anyone have any dealings with RIVES Audio. Are they hype or really worth the investment?

IMHO, to spend that kind of money and not obtain the services of a professional like Rives would be just plain foolish. The only other option might be something like the TacT or Sigtech, which might be used in conjunction with professinal acoustic advise as well. Unless you plan on moving in the near future professional acoustic advise might be the single best investment in audio you make.
Bombaywalla, you bring up some good points. However Dbk is planning on spending up to $50,000 on this system. The cost for an expert opinon that may have greater effect on his total system than any combination of components (except perhaps for the room correction devices previously mentioned )coupled with the experience that an expert may have to keep the reconstruction hassles of his home to a minmum, seems like a bargain to me (of course the caveat about moving still applies). Rooms may effect sound by as much as +/- 10 dB, I can't think of many components that vary that much. The rooms he is considering vary greatly, are not simple square or rectangle boxes and as such would take more than the typical amount of study to get a handle on. Considering that one can not "return" self designed reconstruction efforts, mistakes or dissatisfaction could be quite costly, in both money and aggrevation. Furthermore, if one were to take your advise why stop there? Might as well get an EE degree and design and manufacture all the gear too. Heck, why stop there one could study medicine, law, you get the point. An initial consultation by an expert in a system of this cost may be less than the cost of some cables or a power purifier.
