Others experience re: subs and Magmepan 20

I have a pair of Magnepan 20r’s. Have enjoyed them for years. In my room they go to about 30Hz, response way down at 25Hz.

I am experimenting with a pair of Janis subs. This gets the response to about 25 Hz then down a lot at at 20Hz. It adds a little something but not I am not bowled. over. I hear and feel a bit (in my chest) on some music.

I would like to hear about others have experience with adding subs to nearly full range speakers?

Did you feel you got your money’s worth for "a few silly Hz"?

Thanks

Thanks for reply.

My question is less about what equipment and integration issues (that would a whole, complicated discussion alone) but rather other folks experiences who have tried this and do they feel they got substantial benefit from an extra half octave added to (almost) full range speakers to justify the expense, hassle and real estate taken up in the music room.


Thanks

First iteration of monkeying around: Janis subs are crossed over at 35 Hz at  24 db/octave


Thanks to all who have responded

Stereophile test CD with 50, 40, 31.5, 25 and 20 HZ tones and a Radio Shack analog meter at the listening position I am pretty flat at the 31.5 Hz band (compared to the higher frequencies) and down 10 db or so at 25 without the subs


Music is virtually all/any but mainly rock, folk, classical.

But there are certain songs that I think I'm missing a bit of really low end:

Quick examples

"With God on our side" Neville Brothers

"Sista"  Rachelle Ferrell

"Solomon Sang" Cassandra Wilson


With or without the subs, things sound great;  I can't identify where the sub is located. Two of us listening can identify a little more low end with the subs, but not much.

With the subs, there is a bit of vibration in my chest - sort of fun (at first) but not what I get at the symphony hall and I suspect it will wear thin.

The subs are down at least 10 db at 20 Hz.

Re: an honest and honorable hi end guy

I had the opportunity to speak with Duke of Audiokinesis today.  It was an interesting conversation and we had an extended discussion regarding my setup and various constraints that are present. He evaluated things and felt his Swarm system was not the best solution for me.  He even suggested a competitor product to consider.

It is refreshing/unusual/nice/amazing to find someone in high end who really only wants what is the best for the customer.  

I would strongly recommend Audiokinesis and Duke if his products might be of interest.

Perhaps one from Column A and one from Column B?

Reviewing Rhythmik or Salk (upgraded cabinets with same components) as option.

Anyone care to opine as to whether or not a 12" vs 15"  has inherent advantages for music (no movies) where max sound pressure at seat 100dB and usually far less?  I do have some space constraints and the 15" might be problematic physical wise.  12" is front firing and 15" downfiring and I don't know how to assess what this would do.

Also putting subs behind the Maggies *seems* like a bad idea as I envision the sub output pounding the Magnepan panels and modulating its output.  My thought was to put the sub beside the Magnepans.   Any opinions as to whether this is a real or imagined issue in real world?


Thanks
