Lx-mini REW Umik-1 Measurements

[CentralCoast]

I am new to speaker measurements how is my system looking? Just the left speaker measured.

open image in new tab to view

An externally hosted image should be here but it was not working when we last tested it.

Topping Dx7pro
Pass DIY Lxmini Analog crossover
Elekit TU8600 amp for high freq drivers
Audio Reasearch 150.2 amp for low freq drivers

I'm not able to view the image for some reason.

 

[CentralCoast]

Did you try opening the image in a new tab?

 

[fatmarley]

Yes it does work if you open image in a new tab.

 

[CentralCoast]

Glad to hear it worked.

Was that measured outdoors? Distance?

 

[CentralCoast]

Measured at 6 feet indoors. My room is 20’x 20’. Speaker is 3 feet from back wall.

1/6 octive smoothing. Impulse reflection filter window set to 2.4ms.

How do you like them? I'm running LX521

Do you think the measurement is unsatisfactory in some way??

The measurements suggest rising response above 1Khz. Have you checked the relative sensitivities for your amps and the gain setting for mid/tweeter.? Also the cal file for your mic, has it been applied?

If you like the sound please ignore my questions and carry on enjoying.

i find the lxmini pretty bright compared to my other dsp`d speakers. then again it makes a lot more noise in the back which causes reflections.

I can adjust the full range 4” driver (crossover at 1kHz), with the TU-8600 volume control. I’ll adjust it down to better match the lower frequencies.

I enjoy the LX mini speakers most when playing records via my Pearl 2. The active crossover really smooths the sound when compared to a passive crossover that I built.

It’s expensive to buy all the amps required, but I am happy with the results!

Like you have, I was hoping some speaker measurement experts could comment on the measurements I made.

 

[Davey]

Your measurement (using a 2.4mS window) means pretty much everything below 500Hz is meaningless.

And, the LXmini ASP has a tweaker on the board to adjust either high or low levels relative to the other. So you shouldn't need to adjust your power amp.

Unless the speakers sound bright to you, I'd leave your adjustments alone.

Dave.

At the Linkwitz audio website LxMini design page there is a graph labelled front. Maybe that is useful as a reference.
Don't forget to record your current settings before making adjustments as you may not like the corrections. Your room and furnishings will also modify the sound and your results.You have a lot of things you can configure, so I am sure you will find a good setup.

I’ll look for it. Thanks.
