Where should I cross my components at?

[lost1700 10+ year member]

I have a set of crystal sscs6's installed with 100 watts to each side. Where do I set the crossovers on my amplifier to, and what about the lp and hp filters? Do I adjust my sub amp crossover to match the front stage. I think my sub is set at 80 or 85hz.

Thanks

generally you'll want to hp at 80 hz.

whatever sounds best

i have my highs set to 160 cause theyre 4" stock components that just cant hang at the volumes i listen to

but when i get my 6.5" Oz components installed, probably around 80hz

SOME can handle it lower, especially if they have an 18dB xover already in the passive xovers. just play with it full tilt and see what sounds better, 50 or 80....typically 80 is where u wanna be at, but sometimes 50 sounds better

You're just limited by excursion. As you play lower frequencies, you need to move more and more air to create the same SPL. Not only that but your speakers also have a natural frequency range where it's loud and tapers off at extreme frequencies. For a normal 6.5" woofer, output generally rolls off above 2-3kHz and below 100Hz. Playing past these ranges will normally require some level of EQ boost to maintain a flat response. Below 80Hz, cabin gain helps some and can negate a bit of the loss. However, at some point, you will simply run out of excursion. Xmax is your clean movement range where the cone's movement is relatively linear and accurate. You have a further Xmech range where the movement is limited by the suspension/motor. This is the unclean range and is normally followed by distortion and bottoming out of the woofer. You can't get beyond physics.

So where should you cross? Well, it depends on your hardware, however, a good starting point for a common 6.5" woofer is 80Hz. From there you just play around with different points and see what sounds best. You might end up at 100Hz or 125Hz or down to 60Hz or lower. It depends on how your woofer and sub blend together, how much EQing you are willing to use, as well as how loud you listen to music.

mines are crossed as low as i can get em.. and boosted

i almost dont even need woofers //content.invisioncic.com/y282845/emoticons/up2something.gif.dd110ecf3ae4b76050d87598f2f8de7c.gif

so switch my filters to high pass, and then set the dial to 80hz?

Thanks for the advice

With only 100 watts, 40-50hz will be fine. With 200w (like I have), I cannot cross lower than 80hz because the speakers would just blow. But with 100w, 50hz should be fine, as long as you don't have any bass boost.

I have bass boost on my head unit i think, but I have all that turned off. I will set it around 50 and see what it sounds like. Thanks

I have to run mine at 120hz. My sub at 65 hz. Im missing 55hz of music. I guess I need midbass drivers.//content.invisioncic.com/y282845/emoticons/yumyum.gif.0556df42231b304b9c995aefd13928a8.gif I am bi amping my comps with stupid power right now. I will go active once I have the time to figure it out. Like others said each system is different It takes alot of time and money to get YOUR system right.
