    If possible, a checkbox to calculate the distortion only on the visible area of the RTA graph would be excellent. Often measuring at higher frequency rates makes it much quicker, but there's often a rise in noise above 24 or 48khz. An option to limit the distortion, THD and THD+N calculations...

    I've taken some measurements of an Infinity 1260w both to calculate its TS paramters, as well as measuring the Qtc in the 38.6L sealed box I made for it. REW's calculation for Q of the impedance sweeps is close to but not exactly the same as what I get calculating Qes/Qms/Qts by hand, using the...

    If I have a 6ft^3 enclosure, how do I calculate the brace volume? I don't know what to put into the calculator.
  4. IB - Infinite Baffle Subwoofer Build Projects
    Hi, right now I'm finally planning my new HT room and trying to figure out if I can fit an IB in it. It's gonna be a sealed off, room in room type of HT and around 24x17x9 ft big. No way to cut holes in walls or ceiling. the only way of doing an IB setup would be to build a huge "box". It...

    Hi, I've done an impedance measurement of a driver I had lying around (using a circuit I designed to buffer output and input stages). This is the .mdat file. I don't have a weighted measurement, but that's OK for now. I'm trying to have REW calculate some T/S parameters, but nothing happens...

    Is there a way to use REW to figure out how much room gain I'm getting? I'm in the process of looking for a new sub, or a pair of subs, and understand sealed designs rely on room gain to boost the lowest frequencies. I'm wondering if there's a way to use REW to figure out how much room gain...

    Help me figure out how many watts I need per channel on a receiver. I plan on running 4 floor standing tower speakers and a center on the amp. The other 6 speakers will run off the receiver. 11.2 system. I used this formula sheet as provided by another HTS member. Just don't know how to...

    I've measured my speaker's impedance both with and without the added weights, but now REW won't calculate the T/S parameters for my speaker. I click on the Calculate Parameters button and nothing happens. Please help.

    hello to everyone I wish to ask if there is any math formula for calculate the delay in m/s have researched but not satisfactory results . Any help would be appreciated Best regards Francisco

    What is the proper way to calculate the power consumption of my components so that I buy the right size power conditioner an UPS. The conditioner will manage all gear(blu-ray, cable box/DVR, receiver, Wii, projector, computer, UPS and TV). The UPS will plug into the conditioner and the...

    Is there a such thing as a calculator or equation to estimate a rooms gain curve? I have a livingroom connected to a kitchen with a very large opening between them, that could probably just as well not be there, and I would like to get somewhat of an estimate of what the cabin gain will be like...

    I was wondering, how to calculate how much air a subwoofer moves in L at (x)hz? you have to multiply xmax with SD or vas?
