Yes, they do look like eye balls.
Yes, they will be incorporated into our A/V series kits.
They sound very similar to the GR-T1's. Differences are very subtle.
They were designed to fit the same driver holes as the T-1 and be a direct replacement. The sensitivity of the T-2 is barely lower than the T-1's. For the A/V-1 I had to adjust the one resister value that is used in the series network from 2.2 (sometimes 2.7 depending on the tweeter) to a 1.5 ohm. All else remained the same. The response in the top end was a little bit smoother too.
If you have A/V series speakers with the T-1 keep the T-1's. They are that close in sound.
If you have A/V series speakers and plan on ordering more A/V series kits to match the ones you have, don't worry, they will match.
The really great thing about the new tweeters is consistency.
With the T-1's I would have to work at it to find matched pairs and shoot responses of lots of drivers to find matches. I was able to find matched pairs to send out though.
With the new G-2's finding matched pairs is easy. It's harder to find responses that don't look alike. I shoot the responses on 40 units the other day and finding tweeters with identical responses was pretty easy.
Good quality control goes a long way with me. I am really pleased with these so far.
