These are wonderful speakers sounding quite nice powered by a Yamha M-60 amp and cx-1000 preamp, about 10' from the back walls in my relatively narrow living room. Excellent bass, good soundstage with a touch of imaging.

Now that I know what they are, does anybody in Audiokarma land have any info on these speakers and its passive radiator?:scratch2: Thanks 
I recently received a pair of RSL Nevada XT's from my brother in LA. They appear to be in great shape, except for the passive radiator. I found the disk down inside the enclosure, surround gone.
Am ordering the replacement pr's and am anxious to get these guys fired up. This is the model previously mentioned with the 12 and 8 inch woofer, and EV horn tweeter.
Congratulations on your score. Nevada xt's are truly amazing speakers. The 1989 "Factory Direct" price on them was $400 each. In today's money that would be well in excess of $1,200 for the pair (...and that's equivalent of wholesale). Many of the recording studios in Hollywood swore by them back in the day. I run mine with a 31 band EQ which really brings out their potential.Am ordering the replacement pr's and am anxious to get these guys fired up.

Not yet but its on my to-do list. Haven't decided which to go with.. Solen... Jantzen...? or I thought I'd give Crescendo a try.. I dunno. I think I'll ask Howard what he thinks. Anyone here have any recommendations?Have any of you re-capped the x-overs?Thanks
No Kby, you are not alone. I also have a pair of RSL 6600H's that I purchased from the Torrance Rogersound Labs store location in the late 1970's. By the late 80's I was working for RSL so when the foam surrounds on the woofers went bad I just bought replacement NOS woofers from RSL for cheap since they were no longer using that woofer. Unfortunately my "new" woofers still had "old" foam that didn't last very long so I took the four woofers to Speaker City in Burbank and had them put on butyl rubber surrounds that should hopefully last a long time. The Electro-voice T-35 style horn tweeter spits a tiny bit but apart from that I've always loved how they sound and will never sell them. I also have a pair of 3600's (the final production run) and two pairs of CG-6A's, but the 6600H's are my favorites by far and highly efficient to boot. There are some owners of Elan's here that love them and after the 6600H that was my next favorite late 70's RSL model. In the late 70's RSL also had a tall column "time aligned" model with an slightly rear-angled upper face that sounded superb, but I've never seen a used pair for sale......
