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

Hi randy 11,

    I try to keep an open mid about system changes and improvements.
    But I'm not certain what you mean by your last post comments.

   Could you please elaborate and provide more specifics?

Thanks,
  Tim
Small sound wave launch of an sub will not mate well with the six foot tall wave launch of the 20.

Image and sound field in the low bass will be screwed up!

Be satisfied with quality sound down to 25Hz.

The bragging rites of screwed up sound down to 20 Hz are not worth it! 


randy 11,

     You stated in a previous post, I believe in response to comments I had made about the attributes of my distributed bass array utilizing 4 subs and that I've never had my room's bass response analyzed via mics and software:

" you might be surprised about the bass....
whether it is worth changing the look of the room is another issue."

     Since I wasn't certain what you meant by the comment "you might be surprised about the bass", I requested you elaborate and be more specific in order to clarify your meaning.  
     Since you haven't responded in the few days since my request, I wanted to point out that your comment "you might be surprised about the bass" can be interpreted in 2 opposite ways:

1. It could mean that, if I analyzed the bass response produced in my room of my 4 sub DBA (Distributed Bass Array) system utilizing a mic and software, I would be surprised how well the in-room bass response actually measured.  
    I don't believe this is your meaning, since I would not be surprised in the least to discover that the excellent bass response I consistently perceive in my room is validated by excellent in-room measurement results.

2. It could mean that, if I analyzed the bass response produced in my room of my 4 sub DBA (Distributed Bass Array) system utilizing a mic and software, I would be surprised how poorly the in-room bass response actually measured.

    This is more likely your meaning, since I definitely would be very surprised to learn that the excellent bass response I consistently perceive in my room is not validated by equally excellent in-room measurement results.
     If this were the case, I'll admit I would be initially very confused.  How could something that I perceive as sounding so good measure so poorly?
I think my initial reaction would be that either the measuring equipment or the measuring method are at fault. Either the equipment is not properly measuring the in-room bass response or the specifics of what is being measured do not correlate to how bass response is actually perceived by our ears and brains.
    Even in the highly unlikely possibility that the bass response in my room was measured accurately as poor, however, I'm not sure I would search for an alternative bass system/subs to replace my current DBA.
    I say this because our 'perception' of the sound of our systems is our 'reality'.  
    If the bass system I utilize sounds as extended, as detailed, as seamlessly blended with my main speakers and as close to the real thing as the DBA does, how well or poorly it measures in my room is much less important to me than my perception of how it sounds.
     As I've stated, I use absolutely no mics, DSP, room analysis/room correction software, equalizers or room treatments.
     I am curious, though, how  my system/room's bass response would measure.
     I should point out that when Dr. Geddes and Toole performed testing on their DBA theory in numerous rooms of various sizes and shapes, however,  the bass response measurements of the rooms deploying a DBA system were consistently very good.  I have no reason to think my room using the DEBRA 4 sub DBA system would not measure the bass response at least as equally 'very good', if not even better.  
     

    And finally,  I'm also not certain what you meant when you stated:" whether it is worth changing the look of the room is another issue."
     Why and how would I change anything?


     I still hope you respond and clarify your comments.

Thank you,
  Tim  
if a living room it cannot be too odd looking

you  may well have standing waves as most rooms do, so need to test
randy 11,

    You haven't even explained your comments from your previous post and you're just going to make more cryptic comments?

     I'm not sure why you're avoiding coherent comments in your posts.

 Are you just a poor written communicator?

Are your comments deliberately incoherent and confusing?

Do you care that your comments are completely ineffective and of no value to those they're directed toward because they're so incoherent and confusing?

Are you capable of explaining, elaborating on or just plainly and directly clarifying your comments?

Am I the only one having difficulty making sense of your comments?

Are you just messing with me by being so cryptic?

     I'm honestly uncertain if any, all or some combination of the above explanations apply.  But since your comments are of so little value to me, I suggest you might want to make them understandable or just avoid responding.

Thanks,
  Tim
