Hello, did anyone managed to measure absolute delay of signal using two different soundcard inputs (Mic in: Microfon; Line in (as reference): Loopback cabel with signal)? Or is it only possible to use right channel mic in as reference signal (ref in) and left channel mic in for signal...

Hey acoustical room treatment gurus. As the title implied, I am totally clueless, and this is the very first time I have even opened up such a forum, but I would like to learn. Short of spending hours reading through threads that I am not even sure of which ones to read, please help. For a...

Hi everyone, how do I configure REW to measure the absolute phase correctly? At the moment, REW automatically shifts the time t=0 to the onset of the measured impulse, thus removing the allpass delay due to the physical distance between the source and the microphone. I'm therefore loosing all...

I hate to ask such a simple question, but what number is actually 50 percent and also full wide open out of curiosity? I usually only bring it up to -20db and the volume is kicking good. I just wanted to really know where fifty percent was, so I definitely wouldn't get into distortion. I am...

I'm looking for helpful comments/owners' reviews for a new 7.1 HT speakr setup with choices of the following brands & amp models. My room size is 15X21X9 ft. TV and speakers need to be on the 15ft side. Note that right side of the room is open to kitchen & breakfast area and no wall. I prefer...

I'm somewhat new to ported subs, but I understand the basics. However, what is the absolute maximum port air velocity that can be used without tons of port noise? I am designing two subs, one extends much lower than the other but has much higher port velocity (65m/s). The other doesn't extend as...

Hello, I have a rather simple question, what is the difference in Absolute and Relative volume settings, I noticed most if not all refer to the volume levels as Relative settings -dB as opposed to +dB. I hope I am not showing my ignorance here with this question. Thanks. Jeff

Well my two anarchy drivers arrived today. Hooray! They are sharp looking, beefy little buggers! I have the mdf, walnut burl veneer, and a rising level of anticipation..... now I just need someone to start a thread or publish a design. I have been reading all these other posts of people...

So 14Hz is minimum for LLT, 8Hz is "Bottom C", and I've heard 5Hz is a lot of DIY'ers dream or goal. At some point, there has to be a cut off... 4Hz is after 8 and may still be felt?, 2Hz, 1Hz... 1Hz, but then it is infinite... 1/4, 1/8... So if there was no limit... you won the $350 million...

According to what I have read, when setting up the BFD it should be at the -10db input and set up so that at the maximum listening volume, the output level of the sub from the AVR should be set so that the maximum deepest bass causes the BFD red light to come on for no more than a flicker here...

Can the absolute level be controled with a BFD I want to use a large power amp to drive the sub-ins. Can the BFD be used to set the level I don't want to have to buy a level control(pre) just for the sub-in If that won't work can anyone recommend an inexpensive line level control to put in...
