Crossover question about KEF KAR 160Qs

[Absolution]

Hi all,

I recently came across some KEF KAR 160Qs (my dad had them in box for 15 years). I do not have the KX3 crossovers. I hooked them up and they sound pretty good despite not having the crossovers. I am a bit new to car audio, but I want to use these in a system I am planning to make.

Does anyone have a suggestion on an alternative crossover I could use? Here are the specs I was able to find:

Low pass: 70-150Hz
High pass: 2.5kHz

Crossover points: 2.5/3.3kHz AT 12 DB/OCT
Power handling: 150W

THANKS!

Hi,

From what I can tell they are the recommended x/o settings
for car amplifiers with active x/o's. Its quite reasonable that
the treble high pass is set a little higher than mid low pass.

rgds, sreten.

Note that the KX-3 was used for two systems, one with 6.5" midbasses and one with 5.25" midbasses. (It may have also been used for the ".2" or separate-driver variants, as well as the "Q" or concentric variants.)

2.5kHz, 4th order (24dB/oct) is I think where I ended up with mine.

And congrats! You managed to stumble on some of the finest drive units ever marketed for car-fi. One word of caution: the tweeters are a bit fragile. If you run them active I highly recommend putting a fuse in front of them, or a lightbulb as Andrew Jones & Co did on the KX-3 passive unit.

KX3 crossovers

I have a pair. I'd be willing to sell them. Those are amazing drivers. I have the 160's in my 350z right now. They came with two pairs of KX's, and of course, I only needed one. My email is kostroske14@gmail.com. I'd take $90 plus shipping for them. Let me know.
