Subs with room correction DSP?


I'm in the market for a sub or two, but this time I want a system that will take a microphone reading of the room and give me a correct setting for the sub. 
I've seen these in the past but can't remember who was making them,
Thanks

@macg19 No subwoofer crawl or gimmicky software with "special" mics required.

If you’re using a -6dB sub-bass speaker/s they roll off around 40Hz and simply do not output enough subsonic frequency to excite most rooms standing waves. I’m guessing your using one or two satisfactorily right next to your main speakers which are typically located in the rooms null?

Actual subwoofers output a far lower frequency which can excite a rooms standing waves. The subwoofer crawl IS exactly the gimmick that easily demonstrates the reverse locations of most, if not all, the rooms standing waves for subwoofer positioning in relation to the listening position.

A four sub distributed bass array can eliminate a rooms standing waves all together making the crawl moot. Either method does not require a purpose built room.

 

The ability to process and compensate poorly recorded bass or to simply to kick out the jams with punched up deep bass is really fun audio nonsense. Your happy, we’re happy. Don’t forget the sunscreen.

 

I have two JL Audio F112V2's in my set up and it sounds fantastic! Before purchasing them I borrowed my brothers SVS subs. They were great in his more Home Theater based system, but sounded very sloppy and  bloated in my audio focused room despite many attempts to tighten them up and get some degree of refinement. 

 

@m-db I didn’t say the sub crawl was a gimmick, it is not and I have done it and understand it. What I was suggesting is that it is not necessary if you use 2 subs as an extension of each speaker for 2 channel. You can see my set up in my profile but you are correct in terms of l placement. Also I went with 2 REL T/9x because they are advertised as low bass extensions and not so much a true subwoofer

For a multi channel home theatre set up where very low frequency special effects are in play it’s a different story.

My set up is ideal for 2 channel and a compromise for my 5.2 system. (Which shares the mains and the RELs)

FWIW, the REL crossovers are set to 48Hz, the mains are rated at 50Hz, and the gain is just 5 clicks so they are barely breathing.

Always wear your sunscreen !

 

@macg19  I'm interested in your comment on the Paradigm and Martin Logan subs. I've read some pretty good reviews on them, even here on Audiogon, saying they offered clean tight bass and that the room correction gave a smooth response in the listening position. Have you had a bad experience? Thanks.
