I am not sure that you even understand what I wrote, and I am definitely not sure what you wanted to say. I will try to respond to what I understood you wrote:
"You can see my point about the so-caled Base Boxes...."
No, I do not. As I stated your post makes no sense in respect to suckout at the upper bass, lower mid, he experiences.
"Two of these are a must...."
No they are not, assuming you talk about subwoofers. Two can make positioning easier and play louder, but if you can properly position them and play at sensible levels....
"Low an mids start at the top...in all my speaker setups..."
Have no idea what you are talking about. Physical speakers/boxes, or frequency ranges? But either interpretation does not really ties to discussion, or your previous statements.
"The base boxes help with the uper frcs ...."
Assuming you talk subwoofers, they will not, unless you think something that does not follow previous statements.
"low base 30hz in your nom. room is a myth........most rooms are only ever going to see 50-60hz...good luck"
If you want to say that in a normal room it is not possible to produce less than about 50-60 HZ than I have to say that you are literally clueless in respect to the basics of sound reproduction / physics.

Note: Title should read "As" without double 's'. I would have fixed it but titles can not be edited. Sorry.

But I have measured speakers as low as 25hz -3db in my room. All depends on speakers, amps and placement/room treatment.

My Revel F52's are +3db at 30k.

Most issues I have had experience with is that 250 to 400 suck out

    TYU, think very hard about how an organ pipe differs from a listening room. I will even give you a little hint: there is a loudspeaker in the room. Now the eignemodes of the room create at the listener's location peaks and nulls, just as they do in an organ pipe. But where there isn't a null, one can always measure the output of the loudspeaker, however low the pitch. Indeed, if the room and loudspeaker enclosure are both sealed, you will get response arbitrarily close to DC -- as should be obvious if you consider that the volume of the room is changing.

    I spoke to Wendell at Magnepan today, and to my surprise he had not heard of such an issue, and didn't have any particular suggestions as to what to look into, as there was no obvious way that he could see that the tweeter output would be reduced but functional.
    
    So I'm pretty stuck at this point!

      Sounds like it. Try taking the output of the other crossover to that driver. If the level doesn't then increase, the only thing I can think is that there's some kind of physical problem, e.g., something blocking the movement of part of the diaphragm. This assuming that there's nothing weird going on with e.g., your room -- hard to imagine what would be.

  You responded to the wrong post. It was TYU who made that mistaken claim about low bass. He's repeating an audio myth that was current when I was a kid, 40 years ago. Stale was merely quoting it and pointing out that it's wrong.
What ever you say.. - tyu 10:46:24 11/18/12 (9)
Your Right.....Good luck
- RE: What ever you say.. - russ69 11:16:35 11/18/12 (8)
  I think the first issue is speaker placement, there is a sweet spot for bass with the speakers about 6 feet into the room, perhaps a little more but I think it's where the rear wave can support the front wave. Next, I have to agree with Tyu (who has considerable experience) about the amp. A big amp will certainly add some meat on the bones, so it is one way to improve the situation. Maggies can be lean if not set up perfectly and you also need to have your ear right at mid panel height. I think these 3 things are the key to your issues.
  - RE: What ever you say.. - JLindborg 15:02:46 11/18/12 (7)
    To just say that it's an amp problem that You have a suck out in one of the lower frequencies are just nonsense.
    And certainly when there is no problem at all in even lower frequencies.
    We are NOT talking about putting out 100db here!
    And if we were, a really REALLY bad amp would kneel upon ALL the lower frequencies. Not just some in the middle bass area.
    Again NEVER mind the amp!
    I have driven much tougher speakers with lesser amps with good results. So just stop it. hehehe

      Darn it, yeah I like sweet little amps. And yes I agree that other things are going on in the OPs setup. But I can't believe that some of you guys don't know what a good strong amp brings to the show. Go get yourself a good 350 wpc arc welder and see what it does for you. It will add some of "the beef" this system is missing, even at low volumes. Some times I think the naysayers just don't have the bucks for a big brute, that's fine, but don't knock it until you try one.
      P.S. I heard a demo a while back with NAD's best master series integrated amp and Maggie 1.7s. Guess what? The NAD couldn't get control of the bass? So, when I got home I read the Stereophile review of the amp and they said exactly the same thing. So that makes 3 of us, I guess.

        I agree that You can get a bit more headroom/dynamics from stronger amps on tough speakers.
        I know, I have a pair of Apogee Scintilla 1 Ohm version. hehe
        But I will tell You this. My little 65W Technics amp managed to put up a good fight without being fried or feeling overly powerless.
        It managed to put out around 94db without sounding fatigued.
        Then again my Yamaha PC2602M have a bit more headroom and more relaxed sound with its 260W per channel.
        But it DOES NOT put out an extra 15 freaking db in the 100Hz area and only that area. LOL
        That would be an EQ-amp!!!!
        If it did, I would throw out that amp and call it faulty!
        I mean, what model of amp would I get if I had a problem around 200Hz and not 100Hz?
        What amp should I get if I had a problem around 40Hz and not 100Hz?
        Do You see the ridiculous questioning here?
        It is not the amp!!
        It's an EQ-balance problem caused by factors I mentioned before.
        Am I missing something here or what? :)

        So...all amps sound the same, is that what you are saying?

        "So...all amps sound the same, is that what you are saying? "
        No! Obviously not! hehe
        What I am saying is and what I wrote is that any amp doesn't put out 15db of output at any random frequency. If it did it would be a poor design or faulty.
        Not to mention totally impossible to rely on to be frequency flat.
        Remember, we are talking about more then 15db of output differnence in one speciffic frequency area!!!
        That is not a poweramps business to take care of.
        Cheers!

        And by the way, if You were to use a Krell instead it would have more head room and possibly add some strength to the bass area.
        But it would not boost 100Hz by 15db and leave 55Hz untouched.

        Maybe........Maybe..Not....Never lived in a real Hard,Big Room with his NAD an his MG12...
        But every NAd Or what i Called...MAGic amps..NAD..Old Carver tfm,proton type amps..You No the amps about 25lb but can put out for a sec. 1000 watts...Hell NAd said there amps could sound like tubes..What was it Solf kliping switch on the back..
        All these amps i have ever heard had a suckout in the mids.. because .. All those type.. Had no GUts...
        If he was Driving a pr of Klipsch with a 100db at one watt.. it would sound the same............But he still has a suckout...hehe..good luck

      I was the one who didn't know it was impossible..... to know....
      Hes got a SuckOut...hehe...good luck
