Magnepan 3.5r Owners needed.... No bass


Hello.  Brand new to the site.  I have been into Magnepans for years. 

I have 3.5r speakers which are wonderful.  

But lately it sounds like they have little to no bass.  I have them bi-wired, and when only playing the bass, it is barely there.  Strange because these used to have loads of clean, tight bass.  The mids and the highs still sound spectacular.  No buzzing, no problems.  I've examined them in bright sunlight and there is no delamination on the wires or anything.  Ive taken apart the crossover and measured and it all measures to the correct values according to the schematic.  Why would my Mg12's have loads more bass than my 3.5r's?    Powerful amplifiers.  What sound I do get is beautiful.  But just not getting the bass that this speaker should put out.  

Wondering if anyone with these speakers has experienced this issue.  3.5 or 3.6?  

Any help would be appreciated.  Thanks.

I was searching through posts here doing some research on Magnepans and happened onto this one.  I have got to say somebody here needs serious help, and it ain’t jjss49. It is just some pretty pathetic stuff on display here.

Troll someone else.  I have no interest in you or your weird projections.  

I actually live my life.  I don't spend it in front of a screen attacking people for being direct.  Take your victim routine elsewhere.  

If you have nothing constructive to contribute, say nothing.  

No idea how your trolling hasn't been flagged.  No wonder women don't come on here.  

@jsbelieve  You got my head scratching. Let me just go down the list. Are you in the same room? Did you move anything? Did it happen over time or suddenly? Did you try a different bass amp? And I always suggest checking to make sure your bananas are not pushed in too far. That's everything I can think of.

Thanks so much for getting back, Russ.  

I appreciate all these "basics," lol, but I assure you I've checked them. 

Same room.  Nothing moved.  Happened suddenly.  Same amp.  I've tried others.  Same.  Also not happening with my other Magnepan models.  

I have not checked to see if the bananas were pushed too far in.  I have them pushed in all the way, as always, but actually, that could be.  Are you suggesting a poor contact from being pushed in too far?  Not a bad thing to check.  I mean I certainly pulled all of my connections in and out multiple times, tried different cables, etc.   

The amp I'm using has bi-wiring capability.  Two sets of outputs on rear.  I am not using subs now, so I wire them both to the external crossovers on the 3.5.  

When I plug in my mg12's WOW, the bass is excellent.  Of course they can't match the 3.5's in overall tonal quality, soundstage and realism, but they're lovely speakers nonetheless.  

I'm wondering If there's a connection unglued or something, but it would be odd to occur on both speakers.  

It could just be the terrible room that I'm in, because it is a terrible room, but it never did this before, so it's not.  But you know when you've tried everything, and then start to question things you're sure of?  Like looking for your keys in the refrigerator?? LOL. 

Anyway, I appreciate your response.  Do you also have 3.5r speakers? 

Have you heard of this happening?  

Your earlier post about phase being inverted is exactly what I thought in the beginning.  Everything is connected properly in terms of polarity.  
Also, a few weeks back, my turntable and phono preamp combo began picking up a radio station.  FM, of all things.  That's been driving me nuts, and my lovely noise 

So, double whammy.
