    Building my first house! What should I do for a home theater room + other questions

    Kyle, Find it ($2,000) in your budget to get in touch with Dennis Erskine ( http://www.designcinema.com ). He will give you all the advice you need, and design your theater for you. The $2K is for a fully designed theater that you can DIY at a later date. I recommend contacting him ASAP. Tim

    Help with sound dampening??.....

    I'd listen to the movie soundtracks at a lower level until you house is complete. Soundproofing can be a major undertaking, likely more than you are going to want to deal with in the short term.

    Please help with insulation question - complete HT construction noob

    The best way to minimize bass transmission is reduce the physical connection between the interior walls and exterior walls. That would mean building a room within a room, which might not be practical for you. The other option is some form of resilient channel, onto which you mount a layer of...

    Bulding new dedicated HT need help.

    Omard, The most important consideration is room construction. Audio performance in the theater depends on how the room is built. Not only do you want, I assume, to keep sounds from getting out of the room, you want to prevent outside sounds from getting into the room (that lowers the noise...

    Need another set of eyes: Confirming room modes

    You've probably received his spreadsheet by now, so you'll have an idea of what I'm talking about. Your room dimensions "look" OK just from looking at your website. That is the only thing it would be too late to deal with. Put the dimensions into his spreadsheet and it will tell you for sure...

    Need another set of eyes: Confirming room modes

    I agree with Cees. But also, understand that the spreadsheet assumes perfectly reflective boundaries, which isn't the case, meaning the predicted frequencies and locations may not be accurate. The best thing to do is address reverberation time first and then do an acoustic analysis in the room...

    Home Theater Builder Stage Article

    He did have an article on stage building in a previous issue. I back ordered all the early issues to get it along with other articles.

    Jeff, I sent you an email. PE #245-455 is the dayton IB sub. Cacu, How difficult is it to make the Eros? I was considering making a set of them for a HT. Tim

    Any IB near Vero Beach, FL?

    Thanks Jeff! I would like to hear the IB whether equalized or not. Where in central FL are you located? Are those the MKIII's? Those were one of the drivers I'm considering along with the tempest, tumult, and dayton IB.

    Any IB near Vero Beach, FL?

    Does anybody that lives near Vero Beach, FL have an IB setup they'd be willing to demo? I'm considering building one into my HT, which I've yet to start building, and would like to hear one.

    room width question

    http://tedwhite.homestead.com/Whitepapers.html Buidling a floating ceiling involves putting the ceiling joists between the above floor joists. You should definately use something more than 2x4s for the ceiling joists. Take a look at the above link, you'll see how Ted White built his floating...

    New DIYer starting 1st project

    Just FYI, I tried unibox on my mac and had trouble. Although I think it was a function of the version of excel (MS Offic 98) rather than the computer itself.

    My rectuangular box

    What is your desire for sound isolation? Do you want to minimize sound/vibration transfer to the rest of the house? If you want isolation, and since you are at the house design stage, then look into building a room within a room for the HT. The idea is to minimize physical contact with the...

    Where do I begin, if I want to improve the sound in my room? Other advice needed...

    A couple of things would probably help your interior acoustics. First is the imaging for the front speakers. I can't remember for certain when I looked at your HT (I can't get into the site now), but I didn't see anything on the walls behind them (absorptive panels) to eliminate early...

    Speaker Wire Question

    Speaker Wire Question

    Make sure the wire is CL2 or CL3 rated. There is alot of debate over things like copper purity, number of strands, etc. But it isn't clear as to whether or not the sonic difference among purity and strand difference within a guage is discernable. What does make a difference is diameter (guage)...

    Value of completed HT (when selling turn key)?

    The HT is a finished room, nothing more or less, to a lender. If the appraiser agrees with the asking price for the house, then the bank will give a loan based on the appraiser's opinion. If the appraiser assesses the value lower than what you think the house is worth, and the difference is your...

    Screen position

    The height of your head when seated should be at approximately the lower 1/3 point of the screen. So if your head height is 40" off the floor and the screen is 48" tall, then the screen bottom should be about 24" off the floor. But that is if you're looking straight ahead. If you lean back in a...

    Acoustic Panel Question

    Those blinds will have some diffusive as well as reflective properties. How much of which, I don't know. But they may not be as much of an issue as the front and back walls. Something you could try is a large wall hanging quilt or something to that effect. Put one above the couch on the back...

    Sound proof door?

    It is not surprising that the door you're talking about stops the mids and highs at typical listening levels, but not the lows. What will be accomplished by stuffing a hollow core door with insulation is you'll minimize the door panel's vibration because the fiberglass will absorb energy. Your...

    Things I wish I would have done differently in my project

    I can think of two things right off, and they aren't necessarily independent. I would have done a better job of planning before building. It beats getting to a point in construction and then realizing there is something that I should have considered before starting. Along those lines, I could...

    Need help with DIY projector screen measurements

    Dave, I'm not sure I understand what you mean by a native 16:9 (1.78:1). Before you make your screen, project both a 16:9 and 4:3 (1.33:1) onto your wall without adjusting anything in your projector. I am guessing that since it is a native 16:9 projector, any 4:3 image will be shortened to...

    Standing waves + Bass Traps?

    There is some debate as to whether or not broad band bass absorption is appropriate. It has been argued that since only a few frequencies need to be dealt with, absorption of other frequencies by broad band bass traps will require the need for extra amplification to compensate for the loss of...

    Need help with DIY projector screen measurements

    I have a feeling that newer projectors are much more flexible in their aspect ratio sizing abilities. I'll offer advice based on the projector I have (CRT). With my projector, the image width will be fixed on all material regardless of aspect ratio, that is, 1.33, 1.78, and 2.35:1 will all be...

    What do you think of this vented ACI DV12 sub (model output)

    That is what I was beginning to think. My experience with models, not speaker building models, is that their output can vary considerably. It is informative to see how model output varies among models given the same input data. I have excel, and have used it quite a bit in my line of work...

    What do you think of this vented ACI DV12 sub (model output)

    That is about the age of the ACI drivers I have. So should I not be concerned with port air velocity? Winisd pro says the velocity will be about 93 f/s @ 20Hz through a 4" diameter x 9" long port. The dimensions I gave earlier resulted from my effort to keep the air velocity below 18 f/s...
