Hi to everyone,
I am a new French user of this forum that I discovered a few days ago. I will take time to read posts in coming days as it seems there is a lot of information shared here.
I am also a recent DEQX customer, model HDP-4 that I use as a digital PRE, DAC and linear phase crossover for a 3 amp active system. I used a XILICA digital crossover and REW for months, and decided to move to DEQX to simplify my system, work in full digital and erradicate noises generated by mixing HiFi and Pro devices.
If my first attempt to measure the 3 drivers of the speaker seems good, I do have some difficulties to setup an accurate crossover in between MR and TW. When I look at drivers' measures (100% smooth or less), I can not see difficulties to design a strong 192dB or 300dB linear phase crossover (at specific XO frequency, target curve in between MR and TW is "quite" linear). But when I look at the calibration result, there is a heavy notch that I can not erradicate, even when adjusting XO frequency. I therefore suppose there is a phase issue, but phase graph do not give much information...
How can I analyse in deep the problem to get ridd of this notch? Any comment?
I will see how to post pictures to clarify my problem.
Thanks to all in advance.
Phil
