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 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

Underwood HIFI has an Emerald Physics page that says “new models in late March 2023”

Emailed for an update.

Still, any magnepan owners out there who could chime in on minimum level model to handle 900watts/channel, without blowing up or distorting?

My old listening room for years was 24' wide by 34' long.  Vaulted ceilings. 

Best listening room I've ever been in due to wall materials and some other factors.  I HIGHLY recommend Magnepans for a room like the one you're describing.  

They have serious potential when given the space and not crowded with other things.  Other than a few plants, I had nothing else behind the speakers.  My components were off to the side, which is preferable to between speakers.  When I had that setup, I auditioned many expensive setups and in my head would always think(these don't come close to my system at home.)  I didn't always say it because you don't want to insult someone else's setup that they're enjoying.  And they were some really great rigs.  

But it literally took an $85,000 rig to get into the range of realism and Natural detail that I was getting.  

My point - the room is everything with Maggies and I think most people overlook this.  The room I am currently in is not 30% of what I used to get in my old house.  

But that is what happens when you move to the city.  Unless you have a huge loft or something.  Which many people do have.  

Sound stage in my old room was unlike anything I'd ever heard at any price.  It was not only wide, but so DEEP and holographic that it would stop you in your tracks.  

Amazing.  Sounded gorgeous.  A friend at the time who lived around the corner still had the first pair of Magnepans ever sold.  He bought them new.  They sounded AMAZING.  But again, large rooms, high ceilings.  12 feet, at least. 

I favor this environment for Magnepans and I always suggest this to those interested in Maggies.  

Regarding the sublimes, any other thoughts?  Do you feel they color the sound at all?  Are you satisfied with how they dial things in and tune your system?  Do you feel you're at an advantage sonically?  Cleaner?  Less distortion?  Or just different from passive, as opposed to "better."
