Subwoofers with room correction built in?

@mijostyn…+1,

Most often folks neglect the listening position altogether when going through the time and expense of setting up subs in the corner or alongside walls. It defeats the purpose for the ideal end state. 

I am close to that level of tweaking “get a DSP preamp, MiniDSP, etc.” except not building a passive sub with an external amp like you did. Perhaps, you can sell your DIY kits for the masses:)😀👍

@audioquest4life the elac EQ uses your smartphone mic, but directs you to take a nearfield and then a listening position recording by which to calculate the frequency curve. i’ve seen it demonstrated online and it seems pretty snappy. and yes, velodyne is a little under the radar, but they seem like they mean business with regards to subwoofers. they’ve been doing this built-in EQ for a while it seems.

@mijostyn

The absolute best way of going about this is to get a DSP preamp like the MiniDSP , Anthem STR or DEQX Premate

I have a great dac and preamp and don’t want to do the ADC and DAC through these alternate components for my full signal path. If it was just in the path between my preamp and sub, it would be more appealing. we’ll see how the elac’s EQ does by itself first, but I’m open to tweaks.  This is an interesting option from Underwood hifi by DSpeaker:  8033 SII subwoofer equalizer.  Just for the subwoofer.  

@bigwave thanks for the heads up about this brand, even though they're currently out of commission

Check out Herb R's review of the SVS 3000 MIcro in this month's Stereophile.  He spends a good deal of time on the phone app and the many variables that are constantly adjustable via the app.

@twoleftears yeah, that review got me thinking about this concept again... I found it quite encouraging, but wanted a bigger sub that I could get a deal on.
