I am playing around with the integrated subs in my Strata Minis and I was just wondering if there is any way knowing what frequency I have my crossover set to? I mean, the exact HZ. Most plate amps have a low number/high number listed but thats it... Is there a sure way of knowing the in between?
The crossover "point" isn't one frequency because it's A) impossible to cross over at one frequency with a passive filter placed between the amp and speaker and B) it really screws up the sound when drastic crossover slopes are used. Even with an electronic crossover, the low pass needs to mesh well with the high pass and on top of this, the way the speakers interact with the room will dictate where the crossover needs to be. A crossover is the theoretical point where the response is a certain level below the full-range response for that driver and the frequencies may be attenuated at 6, 12, 18, 24db/octave.
Yes, it's possible to get an idea of where it's crossing over- you can download one of the real-time analysis programs, like Room EQ Wizard, also called REW. It can do a frequency sweep that will tell you of acoustical issues and the overall response of your system, although it's best to have a better mic than computers have. This is more important at the high and low extremes, so you should be able to see the crossover region of your sub. It's best to play through only the front speakers first, get the best response and then add the sub, looking for the smoothest and flattest response. Starting with all speakers playing only guarantees frustration and if everything is set up correctly the first time, it will only be by coincidence.
