ADS L-620

So I picked these up off of CL over the weekend. These are my latest pair of speakers and are quite clearly better than anything else I've owned.

Just amazing highs, mids, and lows. Now my other speakers, which were quite nice, are now terrible. Oh well.

They are amazingly attractive. I'm a nerd for stereos and speakers, so I quickly removed the grills so I could gaze upon those oddly large speaker faces with their itsy little tweeter and that luscious 10" woofer.

These really are head and shoulders better than anything else I've had. I hope to keep them for a good long time. I think these may be a very worthy long term addition. I really just can't believe that they were only $140. Shocked really.
 
just the beggining. Believe me ADS is once in a lifetime. Linkwitz Riley crossovers and full control over the drivers being built to match. The original owner of the company came here to work at NASA. He was an astrophysicist . Extremely good at mathematics and used formulas to get the gauss factors, damping factors, and make the lightest drivers for transient response. Even today most tweeters are heavier than ADS silk dome drivers. They may be older but other than Magnepan nobody can out do them.
 
The L620 is no starter speaker, I have a set, among other ADS speakers, and the L620 deserved their own system in my house, so they reside in my basement cave, as a dedicated analogue system, paired with the NAD 3150, NAD 4150 tuner, yamaha table and some old Magnavox cd player. It is a definite ear opener, and just luscious to listen to for extended time, you really don't need to hunt down the bigger ADS speakers as GD70 suggests, but you won't be disappointed if you do. In my avatar, there are two sets of ADS speakers stacked, the L980 and the L880, both are great sounding, especially together, but the L620 stands quite well against them for overall listening pleasure, just another example of how the designers at ADS had a purpose for every speaker model, maximizing the sound quality to any room or speaker size.

I have the L620's running on a NAD 3080 and they sound alarmingly good, though my point of comparison is quite limited.

That old NAD looks to be a formidable amplifier for the 620's. 90wpc, is more than enough power, and if my NAD amps are any indication, the sound is sublime.:beerchug:
 
I have been reading all about new materials, on a few science sites that I love. Also I have come to find out that 3D printers can make the baskets and the cones out of any materials available. They also 3D print the cabinets. I mean super complex computer aided designed to eliminate resonances and super fine tune T/S parameters. We will be able to listen to the finest sound reproduction to date, well beyond our feeble human bandwidth. And with no distortion or phase anomalies. I just got a gig going at the Emanuel Church in Boston to volunteer as a door person on Saturday mornings. The music ensemble comes in and practices the Sunday pieces and after all the musicians arrive they lock the doors and I get to leave the doors and go into the church to hear them rehearsing. I feel like I have died and went to heaven. These are all professional musicians, both voice and instrumentalists, and to witness how they practice and make small adjustments on classical music is awesome. Ridiculous amount of enjoyment to just watch the doors for a few hours.
 
I think I may be a little crazier than most of you guys. I have accumulated 8 factory ADS L1290/2s and built a center channel to match with the help of the Jedi Rich So. I really have cut down on any distortion. These speakers are very low in distortion to begin with but having 9 of them, I can run them with very low excursion and keep the voice coils within the magnetic gap, and maintain full control of damping, you know start and stop, no ringing, and still get a large output or volume of sound. Some day I will bump in to a better speaker brand, I DOUBT IT, but when I do I will share with all.

Once an ADS owner, there's no looking back! You like those, start looking for the larger models!

He could just look for 3-way models as the 620 is about the same size as the 710 a very respected ads speaker. I know you're talking the 910 or some towers, though.

I was thinking along the lines of L780, L880, and maybe the L980 if they can be found, and agree, the 710 is very good.
 
Love my 420s and 520s. Just saw a pair of early clean 620s on the 'bay for $150, but darn, they are in Michigan. A little too far to drive. I hope to get some ADS 3-ways eventually. I bet the 620s sound great!

Nine 1290s simultaneously? @plugto any pics/video of that system perhaps in a separate thread?

Speaking of center channels, there’s an orphan 620 on the Seattle CL for 50 bones, no affiliation.

The 620 on CL Seattle mentioned above is ME, and no one can buy it! I have removed the listing. I played a handful of mono LPs with that speaker and now it is listed in Orphan Speaker Bingo, because I want to find a mate for it! I’ve been gathering speakers for years and have never gotten lucky with any ADS, except this orphan. If I can’t find it a mate I’m going to home brew a mono turntable to single channel tube amp to single ADS. That’s the dream anyway. Hmmmm
