Hi James,
I have had my Model T Signatures and TC-1 for almost 3 months now. I have been meaning to
give you my impressions, but the signatures just didn't sound quite right on a dedicated
2 channel system. The imaging seemed off, the voices were centered, but other instruments
seemed to be not quite in the right places all the time. In some songs if i moved my head
6 inches to the left the image would shift. It was less noticeable when i ran the speakers
in my surround sound system.
Last week i got to try a new surround sound processor. It said that all the bryston speakers
were out of phase, but my surround speakers(non bryston) were in phase. I checked the wires and
everything was wired correctly. Then i started to think, is it possible that one of the internal
wires were hooked up wrong. I found it hard to believe because you must check each speaker
before shipping, plus all 3 speakers, no way.
Well, today with alan wrench in hand, i first unscrewed the binding post holders on the left Model T Signature
to see how they were wired. This is what i found.
Speaker Binding post Wire clip Color
Tweeter Negative larger white
Positive small blue
Mid Range Negative larger green
Positive small yellow
Woofers Negative larger black
Positive small red
So then i did the unthinkable and started to remove the drivers on the left Model T Signature.
Here is how the wires are clipped onto each driver.
Speaker Binding post Wire clip Color
Tweeter Negative larger white Note that this also matches with the board behind + and -
Positive small blue Note that this also matches with the board behind + and -
Mid Range Negative larger yellow OOPS
Positive small green OOPS
Woofers Negative larger black
Positive small red
The problem is with the mid range, the wires are reversed. Not only the color, but the clip size. I can't reverse the wires on the
driver because the small clip wouldn't fit on the larger post.
I then checked the right speaker and it is the same.
I then reversed My speaker wires at the binding post for the mid range on the Left and
Right Model T Signature. I reran the speaker check on the surround processor and it now reported
that both speakers were in phase.
I then listened to a cd in dedicated 2 channel system(note this is not through the surround processor), and
sure enough the imaging changed dramatically. I could move my head back and forth with no
image shift. Instruments were in there right places. It sounded so much better.
I still have to look at the TC-1, but it may be harder to fix. I assume the upper binding post
has the Mid and Tweeter wires attached, changing My speaker wires at the binding post may fix the mid but
put the tweeter out of phase. So i would have to flip the clips on the mid range driver itself.
But that would not work because the small clip would not fit on the larger speaker post.
Not sure how to fix this one.
James i don't like to jump to conclusions but, this could indicate a bigger problem, if you know what i mean.
But just my Guessing.
BTW i have pictures if you want them.
