Consumer Reports May 1970 Loudspeaker Tests and Rankings

Weren't the AR2ax already getting old by 1970?

Nope, just getting into the second generation version with foam surround woofers and paper dome tweets that started in 1969 and went on well into the 1970's.

I have all of the Conumers Report books from the 50's through the late 70's (my parents had a subscription and never threw them out). They always had a large section dedicated to all types of electronic gear that was covered in their monthly magazine for the the year and I read them over and over again as a kid. Later on when I had enough scratch to buy decent used audio gear I already knew what to look for (although back then I would take whatever I could get :D).

I also subscribed from about that time and still do. I miss the reviews on stereo/hi-fi equipment. It would be great if you scanned in those old articles for us to look at.
 
"In some of their speaker reviews in the later ‘70’s and into the ‘80’s they started including a response curve along with the ratings. I wish they had done that here. It just seems easier sometimes (at least for me, anyway), to see information like this presented in a graphical format as opposed to just trying to make sense of a written description."

"I think you may have misinterpreted what they were trying to do with this part of the test. From the way I took it they were just trying to establish if listening tests by a panel of real people with real ears would collaborate their laboratory tests. They found that they did. To quote, “The panelists were asked to judge which one of the two test speakers produced a sound that was, overall, closer to that of the reference. (We could, of course, switch back and for the between the reference speaker and the test speakers almost instantaneously.) The listeners were told emphatically not to base their judgments on which speaker seemed ‘better’ for music or which they ‘liked’ better, but merely to say which was more faithful to the reference sound.”

Now I just wonder what they used for their “reference speaker” that “we knew provided a wide, smooth frequency response.” They never mention what it is, but that is a speaker I would love to search out and listen to myself."

I was wondering the same thing. What's the reference speaker? Since they wouldn't name it, I guess it'll have to be the Dynaco instead. :D

And yes, I too would have liked to see a response curve. Those are especially-helpful in comparison tests.

I wish I had a huge collection of old hi-fi magazines. That would be so-cool just to have the reviews and ads for all your favorite speakers, amps, turntables, etc.
 
I found this post very informative. Interesting that the Optimus 1's were the highest rated speaker of the second tier, since they often get so little respect. Would love to see an article from CR from about 74-76. Thanks again!

I know that I have several other speaker reviews from all through the '70's. I'll look them over this weekend and see if I can post another one next week sometime. Most of the time they tested and reviewed speakers in this lower end price range, but they did test some higher end ones as well. It should be interesting.
 
Just got the Jan '13 issue. Here's what they're recommending as one of 25 "Great Gifts". :sigh: No review, just the picture and product name.

Amazing timing on this thread. Last night I picked up a pair of Dynaco A25's as well as a pair of Jensen TF3's. Haven't had the chance to compare the two just yet (I'm a Jensen Junkie, if you couldn't tell...). I absolutely love the TF3's but with CR's ratings and this thread, I'm going to have to stop what I'm doing than give the A25's a serious listen!

Thanks very much for posting that article! What an excellent reference find! I saved a copy for future use.

1969-1976 so the AR-2ax was rather new at the time of the test.
One of the AR documents on the web shows the dates of manufacture and other info about the speakers.

This CR article is the one that made the A25 the ubiquitous speaker it is today. Many here on AK have owned a pair of few.

Actually the 2ax started production in late '64 or early '65 when they used the phenolic dome tweeter and the old style alnico cast frame woofer along with the newer single midrange unit. It was basically an upgraded AR2a which ceased production in '64, the primary difference being the use of a single midrange driver instead of the old dual 5 1/4" baffle mounted midrange drivers used in the old 2a system.

In '69 they went to the stamped steel basket alnico "slug magnet" foam surround woofers and the little black paper dome tweeters, then some time around '74 or so they went to ceramic magnet woofers.

I like the original ones from '65 to '68 the best, but they're all good IMO!
 
I actually have a copy of that 1970 consumer reports which I bought on an online auction when I was vasilating between the Dynaco A25 and the KLH Model 6. Based on this article and threads comparing the A25 and the 6, I went with the 6 and have since added 23's, 5's, & 17's. I'm still thinking I'd like to venture into the AR's, Advents, and the Dynaco's. I like the Accoustic Suspension soundstage vs in your face boomy bass and super tweets. They become fatiguing to my ears very quickly.
 
Snip!

This CR article is the one that made the A215 the ubquitous speaker it is today. Many here on AK have owned a pair of few.

I assume you mistyped and mean the Dynaco A25, and I suspect that you are correct. I don’t have any other reviews from other sources other than this CR article, but if memory serves, I believe the Dynaco A25s also had very positive reviews in the specialty HiFi audio press back in the day as well. (Maybe someone else can provide a copy or a reference to one of those articles?) Both of these factors I’m sure contributed to their popularity back in the day, and as you point out, their ubiquitous nature today.
 
The bozo was Amar Bose. He took CR to task in a big way. Bose's future was at stake. The outcome was that CR changed it's review technique for ever more.

Here's an article on that.

I always found it amazing that Bose actually sued over a reviewer's statements regarding his subjective impressions. Glad to see they lost, if only because of the First Amendment "actual malice" requirement.

Very interesting. Thanks for the link.

It is always scary to me when a scientist (in this case the CU researcher) can be sued for their legitimate research and findings. It is not unlike the recent case in Europe (Italy IIRC) where scientists were jailed for failing to predict an earthquake which resulted in the loss of property and life. That is a very dangerous president to set. I'm am certainly glad that Bose lost this lawsuit as well.

With the prevailing anti-science attitude among audiophiles these days, one wonders it doesn't happen more often, by the makers of these magic cables, liquid-filled fuses, etc.

Juries today are easily swayed with pseudo science, given the state of our education system; it would be an easy win for the magic-makers, I'm afraid.

I suppose this has a lot to do with why the good Hi-Fi magazines are gone, and we're left with the likes of Stereophile... :sigh:
 
I have a pair of ADC 303AXs that my dad bought in 1973 (ironically enough) on the strength of a CR review. They've been in daily use since then without a break. And they still sound great -- I haven't touched them. I thought there must be some sound quality degradation over the years, so when I picked up a pair of reconditioned Altec Lansing Model Fives for the music room system, just for laughs I did a side-by-side A/B comparison. Well, there is no comparison -- the 39 year-old untouched ADCs walked on those Altecs. Frequency response, lack of distortion, crispness of highs, nice tight lows -- the ADCs were superior in every way imaginable. All this with a ten-inch woofer, no mid and a paper cone tweeter. CR got this one right. What a great little speaker. Wouldn't sell mine for a thousand bucks.

Had some A-25s too. They were pretty good ...

I need to get to working on these things! I'm getting kind of excited and glad I hung on to them!

Maybe I'm drifting off topic here but I once (long ago) had an AR brochure showing either an AR-1x or AR-1y (?). It was an AR-1 with a tweeter. It's not on your list. I remember the brochure featured Judy Collins.

I'm a big AR fan. If you want to test the waters, AR5s can be had for pretty good money. AR3s go for a whole lot, but the 5s haven't kept pace. All in all, they're very similar speakers. The 5s only give up a little bit on the *very* bottom end.
