I don't know if this thread has been posted before (I apologize if it has) but I thought it would be interesting to hear what others have set as their crossover point for their subwoofer and midrange. I upgraded to a pair of 8 3/4" woofers and a 12" Ultimo, I have been experimenting with crossover points like mad. It also helps to know here your peaks are in your system, but what is your preferred crossover point? Also, what sized driver and what slope do you use for your midbass and subwoofer?

I chose 71 since low-mid 70's seems to be a good happy place for most 6.5-7" midbass drivers in a well treated IB door. I for one will never make a smaller speaker play a bandwidth a larger speaker can do better without any ill effects on staging. I'm running a 7" Scanspeak midbass.

I voted 56hz but its really 55 hz. I like my very full midbass up front. I do have a couple different settings though in the dsp. I go anywhere from 55 up to 80hz depending on how much boom I want.

 

[Hillbilly SQ]

Since I'll be able to change sub and midbass settings again without the laptop I'll likely have a tune with sub and midbass in the 60's for normal listening and then bump the subs up to about 100hz and midbass to about 125 or so when pounding the pavement. When I decide to make the subs jump sq takes a back seat to spl.

You need to check out the speaker's spec first before crossing them.

 

[Hillbilly SQ]

Most of us already know to do that. As a general rule of thumb though MOST 6.5-7" woofers are pretty happy crossed around 80hz in a car door. I do know of people who have crossed drivers that size in the 40's during competition. Those same people also babysit you during the demo and usually only play boring sq tracks that make you want to put a bullet through each ear.

50hz with sub on a 36db slope and the MB on a 24db slope.

I was running an acoustic 80Hz @ 24 dB slope Linkwitz on my car.

My Beyma 8G40 midbass don't get down as low as most car audio drivers. They have an Fs = 70Hz. But I need the sensitivity to match the horns.

Currently at 53hz 12db LW slope on MB and 62hz BW 24db slope with sub. Changed since adding the Arc Black 12 to the mix.

Why would you change the xover point on swapping amps?

Subwoofer not amp.

 

[BlackHHR]

40 hz for everyday use.

Subwoofer not amp.

Aah!!

Good thread! I'm new to this so was surprised to see crossover points so low.
Please also say if you're running a midrange or more between midbass & tweet.

Hah- that's how most car SQ demo's on youtube affected me!

My sub to midbass cx can be anywhere between 40 Hz to 60 Hz.

I can play my 8's down to 20 Hz if I wanted, but I don't like subs above 60 Hz.

It's easy for me to localize things above 60 Hz. I use two 15" subs.

Tool makes for great demo tracks when mid bass and up front bass comes into question.
Active 3 way up front, 8,3, and tweet. 12 in the back .

 

[Orion525iT]

~150hz. Subs in rear quarters just behind the B-pillars, stereo.

 

[ou812]

Holy hell that's high. 63 hz for me.

I as well as most of the other sq people I associate with in person encourage people to use their own music. I tune so pretty much all types of music have an equal chance of sounding equally good. And have an ejector seat to send anyone that plays Spanish Harlem through the roof. If I'm controlling what's being played I've been known to start out with something pure and tame then end with some kind of metal really loud. My system is here to party so that's what it will do!

I tend to have the mid play as low as it's rated for. 63ish but for the L6s I had that mf'er playing down to 30 iirc... Didn't even need a sub...
