Hello All,
I was setting up my speakers for Bi-Wiring (knowing I may not her any difference), and noticed one of my speakers provided no sound if only the low frequency terminals were connected to to amp and the same for the high frequency terminals.
(jumpers removed)
As soon as I connect both the high and low terminals together I get full range sound.
The other speaker was fine, if I connected to low frequencies I got low sound and if connected to the high terminals I got the highs.
I used the same speaker cable to make sure it was not a cable issue.
Everything is OK if I just use the supplied jumpers, but I wanted to try out Bi-Wiring and now think I may not be able to do this given my problem.
Any ideas what could be wrong?
Thanks
Howie

A ground ?
I have been reading about star-grounding and a biwired speaker can't be star-grounded.

Definitely not a ground issue, I think it is the speaker that is the problem. I will contact my Canadian distributer tomorrow. Might need to return it, not sure at this point.

Have you tried swapping the cables going to the two speakers?

Problem Solved!
The speakers internal terminal wiring was connected incorrectly. So much for quality control, anyway, all is good now.
Thanks for your replies

Things happen and historically Emotive quality control on there passive speakers is excellent. They have had problems with there powered monitors having a bad power supply and also ground on there subs. Your problem with the T1 passive speakers is the first I have heard of. Do you like the T1's ? |

Yes, the T1's are excellent. They can get a bit fatiguing when listening for extended periods of time. Having said that, I am used to Magnepan MMGs that sounded very warm and could play all day at high volumes with no fatigue, just my personal experience. It has been difficult replacing the MMGs, however the T1s are up to the challenge for sure - just a different type sound though.

They take a short time to get there. Not long and think about what may be happening as a result of your room. The Magnepan MMGs are well regarded and will be different. High volumes may not be best suited for these speakers. How loud do you play ? |

Not sure if my sound level meter is setup properly but I get an average reading of around 90-95db, any more is just too much

Thanks for your replies Howie A problem like this could occur if either both positive or both negative wires to the speaker terminals are reversed (HF (-) from the crossover connected to LF (-) on the plate); if this is the case then connecting an amp to the positive terminals only or the negative terminals only would result in the circuit being 'open' ( = no sound). This wouldn't be caught by a simple test with the jumpers in place. I will contact our vendor to have them test the HF and LF sections separately with no jumpers installed as a matter of standard practice during production.

Hi Rory
Thanks for your reply. Yes this is indeed what happened. I carefully corrected the internal wiring and everything is OK now.
Now back to some music!
Cheers
Howie
