The elusive "i" ???




This is by no means official or confirmed, just my own thoughts and observation. Could I have stumbled upon a few clues as to what revisions were made to the 1.7 to elevate it to the "i" designation?

I have a pair of new 1.7i speakers in house, so using the trusty flashlight trick, I thought I'd take a look at the crossover through the sock to see if there are any obvious differences. I found a pic of the original 1.7 crossover in an old post using Google for comparison.

Here's what I can see:

A. The 1.7 had a solder tab on the far right that joined the yellow super tweeter wire to a red wire that was connected to the rear fuse/jumper plate. That solder tab is gone in the 1.7i and the yellow super tweeter wire now goes straight to the fuse/jumper plate.

B. The 1.7 had two black Axon True Cap capacitors that are now white capacitors of a different vendor/model that I haven't identified. I also cannot determine by looking through the sock if the values are the same as those values previously posted for the 1.7. Obviously I can't measure them yet either.

C. The red wire that connected the solder tab on the far right has been eliminated along with the solder tab. The yellow super tweeter wire now goes straight to the fuse/jumper plate.

The inductor connections look the same through the sock, but again I cannot verify the value or DCR of the 1.7i inductor without complete access which will come later on. ;)

All of the other wiring connections look the same tracing them with difficulty through the sock. Again though, that is my preliminary observations doing this with limited access.

I know my 1.7i crossover pic looks like a 1950s UFO shot. It's the best I could do through the sock. Clear access will come soon enough!

So, there are some mechanical crossover revisions that I can see, but I don't know if any component values are different. It does appear that two of the crossover capacitors are from a different vendor?

This is just fun speculation on my part. Nothing more, nothing less.
