Re: RS-P WWMTM 3 Way underway ( pic heavy )

Looks like the soundcard is the problem. What kind is it? Did you turn off all the special effects?

its my internal laptop . best i can tell all effects re off and sample rates for playback and mic set to 48k ...

Somewhere there may be a setting that tells the soundcard to take whatever signal comes into the mic, and send it out the output. This has to be turned off. Otherwise when the mic picks up say the 300 hz sweep signal after a 4ms delay, the soundcard mixes that signal back into the signal being sent to the speaker while its trying to produce 500 hz. So the signal sent to the speaker is corrupted. I made up the numbers, but hopefully you understand the idea.

Speak into the mic, and see if you hear your voice come out of the speaker. It should not!

Look at this soundcard output settings. I have the mic input turned off. This may be your issue, or one of them anyway.

Your card might have a line in as well as a mic in. One of my cards or computers worked better with one than the other. I'm not sure which. I believe it was a computer that I no longer have or use.

i know that my machine has 3 different USB ports that run at different rates and my mic does work better plugged into 1 of the 2 that is higher rate . also i hook up to my Onyko amp via HDMI and i think it then bypasses my sound card all together for playback ?

In addition to everything rpb suggested ... when I first started using my Win8 laptop with HOLM, I was getting measurements that looked a lot like yours. The top end was clearly not measuring correctly. The problem in my case turned out to be that HOLM was actually using the built-in laptop webcam mic instead of my Blue Icicle/Dayton mic. For some reason, only one (out of three) of the USB inputs on my laptop will allow the Icicle, if I use either of the other two USB inputs HOLM can't see the Icicle. Once I figured that out, everything was OK.

thanks 50 , i have USB mic and don't have Icicle , but you are right as i've found that the different ports do act different . we are gonna go outside tomorrow morning and try a few different things . i'll let y'all know ....

When I measure in the house, the drivers are 4' off the floor, which is really adequate for most x-over work. That's a big speaker, and could hurt you if it falls on you. I use a 6' ladder when I measure outdoors.

Re: RS-P WWMTM 3 Way underway ( pic heavy )

i got tables and stands that i could use , 4' would be tough but 2-3 is doable . i also have a 1/2 sheet of ply that could simulate a floor ?

Re: RS-P WWMTM 3 Way underway ( pic heavy )

moving outside i believe was it . my first sweep set up the same as i was using inside from 36" , both passes off , 1/12 smooth . what ya think ?

Re: RS-P WWMTM 3 Way underway ( pic heavy )

I think something's wrong. There's no way the speaker is that flat. Disconnect a tweeter, or throw a towel over it and remeasure. Or measure 45 degrees off axis and see if it looks the same. The loopback correction file may be the issue. I'm not being negative. I really don't think the measurement is accurate.

Re: RS-P WWMTM 3 Way underway ( pic heavy )

got ya . no worries , i'm no hurry to move this big b!tch again so i'll be set up for a while .... lol

also that was the calibrated loop-back and the speaker is about 24" up on a table .
