Thank you. Now I succeed to import mls files. But I have problem with design of crossovers which is designed in VituixCAD by another person. I can’t find some blocks like LP1, BEQ in your list. Attached you can see details about the crossover I want to design. Could you help me to design such crossover in your software. Measurement files of that speaker are files which I sent you in previous emails. It seems to me very complicated. I studied your tutorials , but still I’m not able to design my first crossover in Eclipse.

LP1 sounds like Low-pass 1st order. In our software, choose a butterworth low-pass and set the order to 1.
I’m guessing BEQ is just a parametric filter.

Regarding your analog circuit block diagram,
– the tweeter has two HP2 (high pass 2nd order) filter blocks which combine to be a 4th order high pass.
– the midrange effective has a 4th order low-pass, a 4th order high-pass and one parametric
– and the woofer effective has a 7th order low-pass, one parametric and a LEQ (which I don’t know). I think this 7th order is a mistake. It’s probably supposed to be a 4th order low-pass and a 3rd order high-pass.

Regarding your target diagram,
– the tweeter appears to have a 4th order linkwitz-riley high-pass
– the midrange appears to have a 4th order linkwitz-riley high-pass and a 4th order linkwitz-riley low-pass
– the woofer appears to have a 4th order linkwitz-riley low-pass and maybe a 3rd order high-pass.

In FIR Designer M you can use the IIR filters tab to implement all of these filters, and see the summed response. Choose “HPF LR” and “LPF LR” – both 4th order – and “HPF Butter” set to 3rd order.

Regarding your measurement files, they don’t appear to be useful; they are way too chaotic in both magnitude and phase. I suggest you go back to whoever made the measurements for you and have them redone. If they still look like this, maybe have someone experienced check the measurement equipment and measurement setup.

Thank you for the MLS files. We are investigating now.

Can you please email us some of the exported Klippel files? The email address is info at our domain, or send us a message through the contact form on https://eclipseaudio.com/contact/ and we’ll reply from that address.

Did this appear with 4.3.14 (which we released overnight)? Did you experience this with the previous 4.3.13?

Mark, as Musan pointed out, the link to the 4.3.12 version for windows was actually serving 4.3.11. I’ve just corrected the link so try download again.

Actually we managed to replicate the problem and implement a fix. Version 4.3.12 is now ready for download.

(Thanks for finding this.)

Email ‘info’ at our domain. The email address is on the website contact page also.

Thanks a screenshot would be very helpful.

I’m sorry, we can’t replicate the problem. Can you email us a FIR Designer project where you see the problem? There may be something specific to the project that is triggering this.

Noted. We’ll take a look. BTW FIR Designer is now up to 4.3.11. Can you try this and let us know if the problem is still present?

Also, are you on Windows or macOS? The codebases a slightly different.

Hi Nathan,

Can you please email us one of the Systune measurements and we’ll take a look? Email “info” at our domain.

What version were you using before updating?
What version are you using now and are you on Windows or macOS?
What export format are you using?
If you have a specific system file that is exporting oddly, please email that to us also.

Have you tried reinstalling an older version? We retain at least one or two previous versions on the download web page.

Hi Ed,

We’ve confirmed the ‘use settings from current project’ problem in FIR Designer M and FIR Designer, and a fix will be in the next releases.

However we can’t replicate the preferences load/save problem. It’s working fine here on Windows 11 (64 bit ARM). We have some troubleshooting ideas and will followup by email.

Regards,
EA Support

The actual use case would be near zero degrees at 80 hz crossing to almost
180 degrees at 120 Hz, a fairly steep change of phase….. This response is
easy to create by summing a 100 Hz low pass filter with a 100 Hz high pass filter.

2nd order LP and HP filters have a 180 deg phase change but it’s quite wide – over 4 octaves. The phase change you’re after is very steep and will result in a fairly long impulse response.

There’re two ways you could try to achieve this.

– On the FIR Phase Adjust tab, put a minimum phase 1st order all-pass at ~100 Hz and then use multiple 4th order all-passes, either side of 100 Hz, to tighten up phase slope. Or..

– On the “Input” tab, clear the response, make a 3 column TXT file – freq(Hz), mag (dB, all zeros) and phase (deg) – with your desired phase transition, load the file on the “Target->File” tab (and make sure to un-check “Mag only”), use the “FIR Auto Phase” tab to push the impulse (from the “Import” tab) towards your target phase response, then on the “Export” tab, adjust the length and delay until the error is low.

Best regards,

Sorry, one clarification. Our products don’t have an IIR emulation mode specifically for Hypex. It’s possible some of the other filter modes might match, but you would have to test them. You can download demo versions of our products. Our products also output raw IIR filter coefficients, so if Hypex can load coefficients, that’s other option to consider.

Hi Ed,

Apologies for the delay in replying. We’ll check where the Preferences file should be saved and get back to you shortly.
