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.

A couple years ago a friend came to my house he had an app in his phone which showed where the dead spot in my room is. If you don't have the app or a friend who does, get a pair of Dollys from Harbour Freight and keep experimenting with best placement

Not that this tip will solve your bass issue, but, there is a method for cryoing cables/fuses, etc in your frig and freezer. Do a search for the article

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).

I actually have the sublimes.  I like the fact that changing the crossover points is just swapping an inexpensive board, so experimenting isn’t going to break the bank (like tube rolling.. 40 tubes…..)

the outs go to 2 tekton 2-10 subs,  mids and highs to a carver silver seven 900 (atm) and the lows go through a carver a760x.  The amps are feeding tekton Double Impact SE speakers..with single beryllium tweeter and bi-amp wiring.

Why I say (atm) is i am waiting on a new Carver RAM285 to swap for Silver Sevens.

I am looking at magnepans.. have a room that is fairly rectangle at 26x18 with vaulted ceilings.  I do have some room treatments on the walls and the room has a nice thick rug with padding..

What magnepans would you all suggest for the Silver Seven 900s and the room?

yes, I do like my music LOUD but also without distorting; feeling the vibrations in my chest, not just listening with ears  .. well and I work outside around the house alot too..

Physically I did not like the fact that maggies being about the size of most doors, cut my room off. My personal preference is for a much shorter speaker. enter Emerald Physics OB 3.4s which throw as big of a sound stage as my Maggie 3.5Rs, but visually opened up the room (see my Virtual System). Now, if you want more bass they made a version of the 3.4s with both 1 and 2 @ 15" bass drivers.

No longer made but they do come up for sale from time to time at super cheap prices
