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.

Hello, Russ.  I thought the same.  Checked everything.  It's all fine.  

gdnrbob-   Nothing in the system is lacking.  

I used to get very clean and full bass.  Not interested in talking to any more dealers.  Called a few and none were interested in helping find the problem.  As soon as they heard I was not buying something, they tuned out.  I've owned Magnepan speakers for decades.  I know what they need.  Never had an issue before recently.  

 

I thought perhaps someone one here might have experienced the same thing.  If anyone has, please let me know.  

Gracias

op

did you move the speakers?  placement relative to wall behind makes a huge difference in bass response due to potential for doubling or cancellation, given the dipole dispersion of the panels

Well, it is your loss.

No offense, but if you haven't experienced the issue, no need to chime in.  

I already know all about the way Magnepans behave.  I didn't come on here to discuss the basics.
