Subs with room correction DSP?

Martin Logan and Paradigm subs both use Anthem’s ARC Genesis software and a USB mic for room correction. The software can be downloaded for free but I think you have to buy the “Perfect Bass Kit” to get the mic. Unfortunately you cannot use your own mic (like a UMIK-1) with the Anthem ARC software.

Alternatively, buy a miniDSP 2x4HD, UMIK-1 and download REW and any sub can be room corrected. Requires a bit more effort and there is a bit of a learning curve, but IME, it can deliver better results than built in room correction.

Svs has a very good app and you can buy a usb Mike and REW program 

which is very good ,and Svs can assist in this to fine tune your room 

the best self contained Room correction is theJL Audio Fathom subs 

a bit expensive but very accurate and tuneful.

It's JL Audio. They're built like tanks, deep, very fast and tight. The newer versions use their room tuning DSP DARO (II) which is much improved over the earlier versions.REL is good- I had an SHO/510 but more subtle, driven by the speaker leads and did not have any tuning. SVS make a decent one with a decent phone based app to tune it with-but its not in the same league as the JL product imo and my experience. Depending on your budget you can also get the JL CR1 which is a pretty sophisticated - and tonally invisible- active crossover that will really tune the sub, the room and the main speakers. 

I'm really happy with my two older SVS Ultra 13 subs with the upgraded plate amps So now I can adjust every sub parameter from my listening chair because of their DSP app that I have on my smart phone No more running back and forth adjusting subs! I have a 2 channel tube stereo rig and 5.2 AV rig  I ran the Dirac from my Emotiva XMC-2 to intergrate the subs into my room REW also does a very good job and it's free, but you need to buy a mic

The ARC "kit" and SW is a joke. Absolute garbage hardware.

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

This is what I did. Assuming you are not building a home theatre, using 2 subs as bass extensions of your mains is relatively easy. No subwoofer crawl or gimmicky software with "special" mics required.

Alternatively, buy a miniDSP 2x4HD, UMIK-1 and download REW and any sub can be room corrected.

Nonsense. No room correction solution can "room correct" a sub that is in a room that is an acoustic nightmare, which is the case for many of us without purpose built rooms.   

I agree a remote for my RELs would have been nice though.
