My experience adding subwoofers to 2 channel

Well Vin, you've gone and done it. Could it be that you filtered through all the pontification of endless subwoofer suggestions and found you're own suitable success? It certainly sounds that way!

I'll apologize in advance for one last thought. If you find yourself beginning to differentiate between your mains and the subs then I suggest considering Eric's advise.

Keep your eyes peeled for a small used Velodyne DD Plus. You can slave all the Minivees off the DD. The Velodyne Room Optimization program goes much further than Anthem, JL Audio, and even Magico. What took you hours can be accomplished in minutes. You'll gain remote control, volume, six presets of customizable alternative settings for when you go from Paganini to Prince, maybe even one for the SVS.
Just a thought, and again I apologize.

Enjoy the deep end.   

Vinny, did I mention you've gone and done it?
You've made your purchase and the well meaning suggestions just keep on rollin' in. 
Subwoofing is getting popular...


Tim, actually I'm more impressed than thrilled by the economy and positive user comments regarding your DBA Swarm system. You have created a user friendly solution to an often ill informed segment interested in true full range listening. 

I've misplaced a list compiled a few years back of recordings that contain ELF below 20Hz. My Mastering acquaintance in SoCal describes spending great amounts of time mastering the ELF for many of his customers. He's using modified Duntechs/Danley Sound Labs setup for playback. I'm sure we've all heard some of his work misrepresented while driving around.

    I'm willing to assist you in this process but I want to warn you it's going to take some work and trial and error experimenting to properly position and configure the settings.

Very nice offer.

Researching khiak's Canadian Funk Audio 21.0LX subwoofer's their enclosure seems to be well crafted and similar to another successful subwoofer design. 

Tim, I'd suggest obtaining more information on the parameters of their DSP process. Specifically, if they're able to line out their DSP'd signal into the F212s. I was able to do this with an F113v1 from my Velodyne DD and the F113s integration and output improved in my room. 

The F113 is a very fine subwoofer but its crossover and manual adjustability seemed to be a shortcoming in my experience. JL Audio currently markets version 2 processing and a separate CR-1 Crossover component which I have no experience with. 

I would definitely NOT sell your F212 v1s. Good luck with it.

Hi Tim, sorry about the delay in answering your question. I hope this helps somewhat.

  Currently subwoofer digital signal processing (DSP) varies a great deal and so too do thier results. My only in home comparrison with a JL Audio F series Automatic Room Optimization ARO v1 was with my old Velodyne DD-18 (v1). 

   Instructions and methods for both differed greatly and can be reviewed and compared on line. For example:
  The JL F v1 uses a limited amount of manual adjustment (at the sub) before and after the internally generated test tone ARO program. Aside from two channel connection instructions there seemed to be little mention of integration with main speakers other than the basic crossover adjustment. 
  The DD (v1) setup procedures include a test tone disc played via CD player were the in room bass roll off of the main speakers and the sub can be viewed from 200Hz on down. Auto-EQ adjusts the level of the eight preset parametric filters from 100Hz on down. Only Manual-EQ allows adjustment of the frequency, bandwidth, and level of these filters and to further tailor the output desired by the user. The sub is not bound by the Auto-EQ or its limits. All DD adjustments can be performed at the listening position using a laptop or by the supplied remote and a TV.   

  The initial equalization results from JLs ARO were different than the DD. After processing the F113 via the DD Auto then Manual-EQ the equalization graph was only slightly different between the two subs. The JL now had better integration and overall presentation. Surprisingly, its 13" driver was every bit as formidable as the DD-18. The JL Audio F series is a great subwoofer.

  Both manufacturers are now using second versions, JLs DARO v2 with an optional CR-1 Crossover and DD Plus. There is a possibility the Funk Farm software could be applied to khiak's 212s which offer a similar amount of cone surface and twice the motor control than the 21.0LXs.
