  2. Optimized impulse responce of subwoofer; Horn VS Vented box

    DIY Subwoofers - General Discussion
    Hi, I am investigating how to get best possible impulse response from a sub that will go all the way or close to 20Hz.

    Electronic Processing/Equalization Devices
    Hi, I own a vintage stereo receiver and a CD player. I recently purchased a miniDSP and a UMIK-1 to try to improve my audio experience. The problem is that miniDSP has too few filters for my room to be adequately corrected. Is there a computer program that could transform a ripped cd file by...

    What are the pros/cons of simply using the default plot WinISD gives for a particular driver in a particular alignment. Please, for now, ignore room gain as well as room peaks and nodes
  8. what am I missing for impulse responce?

    REW Forum
    This is going to be one of those dumb questions. I’m sure the help files tell how to do this and I’m just not comprehending it. I’m trying to do an impulse response with rew and I’m missing something. Shouldn’t the sweep produce that loud click noise? Is there a pull down menu option that I’m...
