Could some one please help with the driver speaker impedance for T Ref and also at the binding posts .
We had a storm and it smoked 2 channels on Emotiva XPA , this has been repaired but want to check speaker before powering back up .

Hi green, There a few things that might help with determining if your Triton Reference towers are working properly.

First, when looking at the passive speaker components used in this tower, these components are not normally damaged by a storm/power surge. When exposed to a power surge, the tower's built-in amplifier (and possibly their passive crossover network) could could be damaged, but it's unlikely the midranges and woofers themselves would be damaged. When the amplifiers built-into these towers are damaged, they will most likely not produce any bass - or they'll produce bad sounds on their own. When a passive crossover goes bad, it will normally block any sound from passing to the midranges or tweeters - or greatly reduce the sound that passed through to the midranges and tweeters.

When looking at the passive speaker components, I would consider gently pushing on the center part of each of the midrange and woofer cones to make sure you do not hear or feel any scrapping from these cones. The cones should move in and out smoothly. (This will help to determine if the voice coil or voice coil formers are bent or not.)

Taking an ohm meter to the binding posts of the tower would not provide a meaningful measurement. At that point, you would be measuring the input impedance of the built-in subwoofer amplifier - and not the impedance of any of the speaker components.

Thanks for the quick response.
I have done the movement test and they move freely. Could not see any visible damage on cross over .
However did find lose solder residue between the Fets legs on on board and fuse was blown .
Have cleaned it up and replaced fuse .
Have powered up speakers without any input all seems fine as it switches on and then times out.
Was just worried as Iam getting less than 1 ohm load on the binding posts .
Have done the battery test and can hear speakers click.
Hopefully all is well and get many years of listening.

Pls tell Sandy I still have Polk SRT running and going strong .
Thanks

Did Sandy have anything to do with the design of the Polk SRT system? From my understanding, he parted ways with Polk Audio in 1988. I still own a pair of Polk SDA-CRS stand mount speakers and enjoy them very much.

Hi anthem, Sandy was instrumental with the development of the SDA technology when he was with Polk Audio in the 1980s, however, he had left Polk Audio by the time the SRT system was introduced.
