908 0r 902?

FWIW, IMO&E 902 wins hands down for HF extension. The older style 802's with the annular slit steel phase plugs will render the most "seamless" transition at 500hz and 800hz XO points. Ironically, for my preferences, this leaves the 802G as the least desirable in terms of sonic performance. A little further irony, even though i own examples of all the small format Altec drivers and am fond of them all, i probably spend the most time listening to Renkus SSD-1800's which, IMO, have a combination of the best attributes of the 902, and early style 802 all done with a diaphragm that has a mylar surround but should not be confused with a Symbiotik Altec.

Note.....Renkus SSD-1800 diaphragms are no longer made, but if your quick......http://www.google.com/url?sa=t&rct=j...MOqR8g&cad=rja

I think i still have one NOS phragm left somewhere, i bought 4 about 10 years ago from a mastering studio not too far from here that was also a parts supplier for the microphone and speaker repair industry. I've never needed a replacement, so ebay'd the others off here and there for "play" money. I've never really counted, but i probably have ~50 working Altec/Emilar/Renkus small format drivers floating around here. I've got spares to last the rest of my lifetime, or for as long as i can still hear, whichever comes first.

FWIW, a few years back a gentleman(who's name escapes me, apologies) posted here or maybe at AK or both who had worked with Jonas Renkus. I think our friend Steve Schell can fill in the blanks where my memory fails, as i believe this gentleman was staying with Steve at or around the time of his posting. he gave some great insight into the diaphragm construction, i think he helped Renkus develop the "tri-laminate" material that the phragms are constructed from.

Maybe some of the old posts have survived the various server migrations, i'll do some searching and see what i can find.
