Please Suggest An Electronic Crossover


Speakers:  Infinity Kappa 9

Preamp:   Audio Research Reference 3

I’m looking to find an external crossover to add to my system.  Preferably a pre-owned unit…will consider new unit.

Would like to limit to $1k…but will go to 2k for the right unit.

To expand 2 way or 3 way speakers.  

Single DAC or a DAC for each channel?
or use the DAC from the crossover?

Digital crossover convert analog to digital back to analog.
MiniDSP does have a multiple crossover board that has a built in dac or just outputs digital but would require a DAC for each crossover point



So is the External for the Kappa? You want to remove the  stock XO and add your own? Take care of the dip below 1 ohm? Amp killers..

erik_squires …. I am looking to bypass the internal crossover in the Kappa 9 speakers.

 I am looking to improve on the existing internal crossover in the speaker.


Hey Mitch,

That's a good plan, but those crossovers are complicated.  They do more than simple low pass/high pass slopes but include impedance and frequency equalization.

You'll want a miniDSP for this. You'll also want to understand how the original crossovers worked though and I encourage you to learn to do a complete speaker analysis before attempting this. This isn't something you can do by ear so you'll need to have a measurement kit.

DIYaudio is a good place to go for help, far better than audiogon. If you go with Room EQ Wizard those forums are also going to be helpful.

Best,

Erik
