This is one of the reasons why I bought my Scarlett 2i2 interface, so I can access 2 stereo output channels. Channel 1 (Left and Right) is for the speakers being measured, and Channel 2 (with 1/4” jack splitter to L/R stereo RCA outputs) is typically dedicated as the timing reference (using a...

I tried EQ'ing the aligned sum of the woofers, mid & tweeters, and got a real mess. Ran multiple scenarios (about 20) and could not get anything that measured better (Indoors) than what I already have (see post #26) So Im going back to basics, instead of aligning all the drivers into one file...

Today i'm starting the merging and EQ process, so I wanted to document first steps. I'll be using the outdoor measurements already posted at #31. I wanted to see how the woofer and mid/tweet align at various XO points so, using the REW Alignment Tool, I tried 4 different combinations that seem...

Today I measured the Left and Right in-room response with exactly the same REW settings, plus measured the distance to the microphone to be EXACTLY 8' which is also how far the tweeter centers are from each other. Since I posted the in-room measurement on Post # 26, I have done NO TWEAKING to...

Thanks Steve, the fun is just beginning! :cool:

Thanks Cristiano, my system will be a hybrid crossover, The plan to use the existing passive XO for the Midrange to Tweeter transition, and the the MiniDSP 2x4HD for the Woofer to Midrange crossover. Now that I have better measurements, I want to see (hear?) whether he DSP crossover works...

Hi Cristianolo, thanks for your response! Ive seen many "standards" for windowing and smoothing, and am still trying to figure out what makes sense to me and why. Consider me a stubborn work in process. :cool: The 0ms point I believe is set by the acoustical reference (fullrange single...

Yes! - I was able to spend some time measuring outdoors yesterday, and this is what I got: The solid blue line is a fullrange measurement of the speaker with stock XO all around at 1m and amp output somewhere betwee 1v and 1.4v. The dashed green lines are the twin woofers both at 1m (for delay...

Cool!, thanks!!! I need to look into this. I don’t know enough about baffle step, so I’ll be researching that for sure. Impressed at how flat you were able to get the FR graph, with just two or three filters. But first, I want to measure the speaker again in a quasi-anechoic setting (my...

It's slow--going, busy time of year. I'll post progress along the way. Thanks for checking-in! Sixto

The new USB interface works! - I've run a few measurements in REW of the current in-room response as an updated baseline. It still looks rough with lots of reflections, but is more even than what I got from the old interface. I did get some funny messages about clipping in the reference...

Took a while, after several calls to product support (these guys were great) but we finally came to the conclusion that my USB interface has a hardware problem we can't fix with Phone Support, so I am going through their trade-in process and hope to get a brand-new Scarlett V4 soon so I can...

Thanks! I will keep my eye out for a deal Steve, thanks for taking the time to provide such a thoughtful response. While I wait to connect with Focusrite, I’ve been reading tons of threads on this forum, and running various measurement scenarios to see what works better using the Tascam USB...

Do you really need to separate the filters for the LP and HP? Why not generate one filter file and import it into all 4 MiniDSP channels? The filters will only act on the Frequency Range you are assigning to each driver.

While I wait for an answer from Focusrite (repair the broken unit or buy new) I figured I'd go ahead and re-measure the individual driver responses without any XO using the Tascam USB interface. I also did the woofer as a single driver, at close range, though I have not yet corrected it for...
