What do you mean by auto tune setting the tone controls ?

So in my car I have a Pioneer headunit that has auto tune. you just plug in the tuning mic and attach it to the headrest in the drivers chair. The headunit automaticly adjusts time alignment of all the drivers, and sets eq about as flat as it can. In my experience this method works WAY better than anything I have ever been able to create myself 🙂

Is there anything available in Home theater that does this??? This would allow me to build a fully active speaker and simply run auto tune and you're done! (just like car audio has been doing for a long time)

even for individual driven speakers? (active crossovers)

What I think you're asking is whether an AVR can individually tune each element (tweeter, Mid, woofer) of a set of speakers as might occur in a car. The short answer is no. AVRs have auto-calibration but it treats each full range channel as a discrete unit and will tune by channel not by driver. It's slightly more complex than that, as they can pass some signal to a sub-woofer channel, but that's very limited.



I've been playing with alternative devices such as the MiniDSP 4x2 which acts as a crossover and can set individual drivers characteristics - such as setting the frequency range to be passed, output level and delay. That's not an automated process, though some tools (REW for one) can help. Some of the newer units may have better capabilities. Someone else will have to comment on that.



I don't offhand know an easy way to achieve an automated setup for multi-channel audio in the home environment. You could try using full-range drivers or see if you can transplant a car audio setup to a home environment. I suspect they'd struggle in a large room and you'd have to build custom enclosures.

I am amazed every day, how in a world of Alexa, siri, and driverless cars, that Home theater systems still use passive crossovers!

How long will it be until the industry recognizes the need for fully powered individualized drivers and crossover control?

Pioneer has had autotune for at LEAST the last decade 🙂 And a CAR has A LOT more variables than a house !

Strong dependence on the location of speakers and subwoofers in a particular living space. Various configurations and acoustic characteristics of living quarters. It's easier with the car interior.
Different results at different points in the room. There is no binding to the driver's seat 🙂
