Subs with room correction DSP?

The Elac Varro series has automated room correction, though I don’t know the details (how many bands it adjusts, for example). Review here. I believe it takes its measurements with a smartphone or tablet.

The SVS models come with an app with three PEQ points, but you need to measure them independently to make the settings. I wouldn’t be surprised if there are iPad apps for measuring frequency response, but I don’t know for a fact.

The apps are a definite improvement over running back and forth, which gets tiresome and breaks concentration.

I’m in the market for a sub or two

You might start by researching the value of two, or more subwoofers vs. one.

Also, it would be great to see what your system looks like under virtual system. What frequency range should the subs be covering? How big is your room? What are the room dimensions?

Another question that I have is why don’t more manufacturers offer subwoofer DSP? What is the downside of DSP? I can see that the upside might be the ability to place the subwoofer(s) in less than ideal position. Is DSP one of the top features needed when shopping for subwoofers?

I recognize that you simply asked for DSP subwoofer brands/models, but I guess that I’m asking why DSP and is this the best solution for your room/equipment? I went with REL and it did take some work to get things right, but that was a one time effort.  One of the main challenges that I had with bass was keeping the stylus/cartridge/tonearm/platter free from the subwoofer output.  This issue extends beyond analog play, but can also act upon other components.

Lastly, are you trying to get things right within a two cubic foot listening box, or will you need to consider a larger listening area?  This is an important question and one that goes back to subwoofer placement, type and number.

I believe SVS and now Hsu offer some sort of app that lets you configure the sub from your listening location.

I don't know about Hsu, but I have two SVS subs. The app includes PEQ, phase, level, polarity, low-pass filtering, and more. All configuration can be done from the listening chair.

The SVS is looking good. 
Yes there is an app to control it, but it's still just guesswork without a program to measure the frequency response of the room.
