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 could not think of anything. Then I thought maybe the phase is reversed in one channel? Check it out before going deeper.

@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. 

I have not checked to see if the bananas were pushed too far in. 

Do you also have 3.5r speakers

The connectors can contact the circuit sometimes and do exactly what you are describing. I have not owned 3.5s but I helped my brother set up his 3.6s. (We solved the bass issue with Infinity RS1B towers).
