[QUOTE="squeak9798, post: 552979, member: 555320"] Those are peerless, not scanspeak. And yes, the Koda tweets are modified versions of the Peerless RDC2000. From what I've seen Dan post in the past, they (Adire) had the RDC2000 modified for better off-axis response and a little smoother top-end frequency response (notice the huge peak from ~5K on up on the RDC2000 FR graph). So they aren't [I]exactly[/I] the same, but the Adire tweet is definitely very close and is based off of the RDC2000.

And one last thing to watch out for when looking for a new tweeter is the Fs. General rule of thumb is that the tweet needs to be crossed over at a minimum of twice it's Fs. So, if you're components have a crossover point of 3khz (for example) and you buy a tweet with a Fs of 2khz (which would mean it needs a xover point around 4khz), then they may not work together well.
