A/D/S L1 speakers ??

They look around the same size as my 70's ADS L-10 speakers, which BTW, used 7" woofers in acoustic suspension cabinets.

Dang. I hope it works out.

Although the tweeters'offset isn't mirror imaged, they still reproduce the stereo image very well. The offset is made to reduce baffle diffraction and to avoid response lobing.
 
Haven't posted here in quite a while but came across this thread and had to put in my 2 cents worth--
I just acquired a pair of a/d/s L1's from the goodwill website, I have been an a/d/s fan for a while and have owned several of their products including the L-1290's which I recently sold. The L1 may just be the best sounding a/d/s speaker I have heard, and that's comparing them to the 2 1/2 -way tower 1290's with dual 8" mid-woofers and a separate mid. The L1's just sound phenomenal, although I am not well versed enough in the technical aspect of speakers to tell you exactly why. Their soundstage is enormous but very intimate, and they seem to cover pretty much the same range that the 1290s covered. Their dynamics are fabulous-punchy and weighty but not bloated or loose. I don't ever want to use the cliched "I heard things I never heard before" line, so I won't. What I WILL say is that they give CDs I have heard over and over again a completely new presentation. These are CDs that I have listed to thousands of times and am very familiar with, and there are certain instruments that just come right out at you on these L1's where they don't on any other speaker (I am not even sure they did like this on the 1290's.)
If these are still available I HIGHLY recommend picking them up- I am very impressed with mine and plan on keeping them for quite a while. I recently snagged a couple of M&K S-85s with the LDM-125 docking module stands from a pawn shop and thought they would be my reference speakers for a long time, but these L1s just beat them overall. The S-85s MAY be more accurate, and they do sound good, but they may be accurate to a fault-- they do not seem to have a "signature sound" that I like from speakers. The L1's do in spades, so the M&K's are about to go bye bye. Hope this can help in some way.
 
This sounds promising:

"The L500 & L520 IMO do not get bested in sound quality until the later B8/L8e.There is also the near mythical L1 which was essentially an L520 in the later style cabinet w/ angled grilles. I would love to find a set of those but doubtful."

Hi, I have both the L520 bronze grill and as you said the mythical L1. Both are great but I think the L1 is tighter. Im runnig them with the PB 1500 system. Pure majic. Im the only one that I have found on web with a pair. I know Soundmotor speaks highly of them both. Some guy in Boulder Co had both I snagged both for 3 bills.
 
Nice but you do realize the original post is over 8 years old. No big deal, just sayin’.....
 
Fellow L1 owner bumping this. Would be fun to find out how many were built...

I have serial numbers 00237-2 and 001348-1.

Bottom says ADS Analog & Systems, Inc :smoke:
 
Hi.Yeah seem to be rare as clean air. My numbers are nice and close to each other.001248 -1. 001252 -1. I have been running these for the past 8 years and my L520's sit in bags in the closet until last week, Such classy speakers the L 520's are, Both my pairs are mint with the exception a few scratches on the bottoms. I notice that the L520 pair have better base response, great height and depth yet narrower sound stage than the L1's have. I think they may be a bit more forward also but nothing to complain about. Running Tube preamp into Belles Research 150 75wpc and 250 125wpc. Seems to take both very well. Using an old Yamaha PF-Turntable/Grado 1 cartridge and Roksan cd player. I also have the ADS Sub system PB1500 which is a gem but unneeded. These speakers rock, I had a pair of the L1530's before these and had to downsize in living quarters. Those were the cream for sure however these give me the same sound stage and volume and clarity in a smaller package which works,I doubt if we will ever get the L1 interest off the ground but we know that/s ok.
 
For those who have heard them (the L1's), how would these compare with Dynaco A25's (if you've also familiar with those)? Any good with rock music?
 
Another first for me. I’ve never heard of the L1s. I thought someone was talking about the L10s, but once I saw an L1 I knew they’re not the same speakers, although they do seem to share drivers.
