Can you list your source for 2As with side-by-side tweeters? If not, I think we can put this to bed.
My list of drivers clearly states 2 - sl2000 tweets for the 2A. The sentence on page 7 is a bit confusing. After reading the paragraph over a couple times it does seem to indicate a single tweeter. My copy must have a typo when it lists the drivers for the 2A's, which was subsequently corrected in the dl version.
So yes, lets' put this to bed because who cares, if he has a single tweeter, then he has a single tweeter. I do know of 2A's which were early runs having 2 tweeters, perhaps they were mis-identified. We ALL know Polk and transitional models can be hard to classify. That's the best evidence you're going to get, unless it comes from Communist China.
Here is a photo of the 3rd generation driver list from the Final SDA Compendium.
So far my understanding is that the dimensional drivers play a signal that is equal to the Left minus Right (or r-l) signal. Essentially only those portions of the signal that is different between the left and right channels. I have understood this principal to be the same in all models with the only differences being the # of drivers (of which all play the same signal in the dimensional circuit) and the wiring of this circuit in TL-able models vs earlier versions. As mentioned earlier, I do understand the progressive point source design in the multi tweeter models, but this is not associated with the dimensional circuits. I would like to learn more about this if I have been incorrect in my understanding.
is there somewhere I may be able to download the information from the sources pictured from you two guys?
I think Polkieman may have posted a link to one of those in another thread but it doesn't appear to be the one H-9 has. Where may I find that one, and is the link to the one in the other thread the same as the one Westmassguy has here? here is the link...
I think that everyone here tends to lose sight of the fact that EVERY SDA model, when it was introduced and offered for sale to the audio public.........was the Cat's A$$ at that moment in time, and the sound was what they wanted it to be ! I'm pretty sure that without the benefit of a hindsight view, any of the SDA models would be regarded as great sounding speakers, absent any others for purposes of comparison. I personally think that the sound/effect from stock 1As is great and I actually wish that my SRS2s sounded a little more like the 1As in the dimensional department. Attachment 83161
Out of print means out of print, afraid you're out of luck. H9 has it because he paid for it......
