    New HT walls/acoustics

    Symmetry, especially between left and right is important to the soundstage. As suggested, build the open frame wall mass up. Two thick, but dissimilar layers of Type C gypsum with RoomDamp2 visco-elastic damping compound in-between for the interior side would be a good, inexpensive performer. If...

    How to approach an HT room

    Jonnythan, Good question. At minimum, you want to attenuate any first order reflections that are within 15 dB of the direct signal down to at least 500Hz. This would mean the treatment needs to be at least 2' wide to cover the wavelength. Be suspect if the product does not have a data...

    How to approach an HT room

    Jonnyhtan, You can find the first order reflection points by doing the math or, with the help of an assistant holding a mirror flat against the walls, ceiling and floor, mark the points where you see the tweeter from the listening position. Our metu panels are broadband and customizable to...

    Building new home, need HT Room advice.

    The room dimensions mentioned are not great for room mode distribution, nor functionality. I would suggest going larger. A flat ceiling is recommended for room mode control, costs and probably some noise control issues. Placing the door at the rear is ideal. Two layers of drywall with a damping...

    How Important Is Proper Room Treatment For Audiophiles?

    It doesn't matter what kind of room it is, acoustic treatments will be needed in order to make it sound more accurate. Noise control, room modes, first order reflections and reverberation times are all issues that probably need attention, but optimizing your speaker/listener positions within the...

    New room construction: overall acoustics

    Remember that noise control is a system approach of principals incorporating blocking, breaking, isolating and/or absorbing sound waves and vibrations. Remember too that it will only be as good as it's weakest link, so be careful of doors, windows and other penetrations in the system. I don't...
