I recently got my hands on an Eclipse 8455 and all I have to say is... wow! I plan to use it in 3-way mode with a 5-channel amp running front components and a single sub. My question is about how to best set each channel's time correction by ear.
I know that setting time delay for each individual tweeter/midbass will be a daunting task. So, rather than play music and making the adjustments, I am wondering if the following setups may help to adjust delay more easily or more accurately:
1) using test tones or patterns instead of music, such as sine waves, white noise, some other synthesized waveform. Or, sounds such as repeating "clicks" for example. I assume that sounds with sharp transients would make time differences between drivers easeier to hear, and therefore easier to adjust.
2) Playing the above sounds while the midbass and tweeter are both playing full-range and NOT crossed over. Phase differences in the resulting overlapping freq. ranges can be more apparent - and easier to correct. Of course, music or white noise would be excluded due to possible tweeter damage... but test tones or waveforms could be limited to a bandwidth safe for both drivers, say around 2000 - 3000Hz. In theory it should be easier to correct delay while hearing the same sound from both drivers, right?
Sorry to make this so long, but I will be making adjustments myself without any test equipment other than what's on the head unit. Is there an accepted method that you pro's use to adjust time delay? any info would be eagerly appreciated! Thanks in advance.
