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

highpass was set at 200 . here is what i set up for . both passes checked off from 40"

What is the sweep highpass set at? Anything over about two or three hundred will make the top end drop like a cliff. There's probably no reason to set it higher than 60 hz.

One of my computers rolled off the top like that with the headphone connection, but not the other output. (Or it might have been the other way around.)

Soundcard issues can be difficult to figure out sometimes.

Make sure no one changed the treble setting.

thanks Kerry , here is pic that shows what i'm talking about , i was set up at over 3ft for a whole speaker measurement and took a look at my mid X ...

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

alright guys i'm gonna need some help getting good measurements . Josh has got the aluminum version together and had to make some XO changes , we're not sure that i'm gonna have to yet but some good pics would go along way . first my mic shuts down on the top octave around 15k in the near field and farther out it shuts down around 7-8k . also my space is very small and cluttered so i do get some noise . thinking of going outside but i do have a busy noisy road out front . i am using UMM-6 and Holm impulse . any thoughts , suggestions or advice would be greatly appreciated ...

Thanks
Mark

I've had the same issue with HolmImpulse. I had to play with the settings a lot to get it to extend out to about 18.5-19khz. I used a weird sampling rate. Like 170something hz or something and had to keep reinitializing and restarting the stream. I would take a measurement, reset/reinitialize, and keep doing this until I got a response that worked. It only worked on this sample rate. Anythinge else was a little messed up.

i looked at those before deciding to build these Joey , the impedance load scared me . i would of needed a new amp as well . these are 7.5 nominal ...

Yeah, CJD stays pretty dedicated to separates. His stuff is so good though. Love it.

Definitely would be nice to have an AVR friendly version.

Similar aluminum version with larger mids.....

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

They look great!

They are too far from the wall. The bass will improve a lot if they are 3 feet or less from the back wall to the speaker face.

If anyone is interested, I have begun construction of an all-aluminum version of these.

good call !

and git - r - done !!! your only a few hours north , maybe i drag these up there for day when i finish them ....

slow season has hit with a vengeance and the guys at work that watched most of the build wanted to hear them , so ....

in this big space they look kinda small and sound a lil thin ...

thanks for the answer Wolf , i was going through my notes trying to find it hoping Josh would see it .

I'm curious about the series 0.04mH inductor you're using in front of the tweeter filter (on your schematic). What role does that play?

That's one way to tilt down the topend on the RS28F, as it has a top-octave rise. The other method would be a CR across the tweeter.

I rarely use glue on my pegboard xovers. Usually for nothing more than to keep conductors isolated if necessary.
On the larger coils or caps, you would use more zipties. I got a ziptie-gun for Christmas last year, and I love it!
No need for adhesives, and stuff becomes modular and easily tweaked.
