The Birth Of The AR-5

Re: A 1968 AR advertisement:

Dear ‘linedrive’, I’m in awe right now from this ad/photo!

As an avid AR-buff since the late sixties, early seventies, I’ve never actually seen this ‘ad’ or photo or whatever it is. With my knowledge of photography and ‘Photoshop’, I almost have to wonder if it’s real or contrived?

Pardon my doubt, but surely you and anyone else might feel the same.

I trust your contribution to this site is ‘real’, but again to see it,this ad is almost unreal.

Thanks for sharing it; it makes me wonder if you have any other ads as bizarre or as wonderful as this one and what was actually in the minds of the AR staff and management? It almost makes me feel even more special about my love for this vintage line of speakers, I must be correct about my whole affliction for them.

Thanks again and I will add; this has been quite a treat!

P.S. It's all very funny also as in 1972 when I took the plunge to buy my first set of AR's, my budget only really permitted AR-2ax's and that was stretching it; I was fantasizing about going for the AR-5's. At the last minute my heart and soul said: the 3a's must be the last word and so far away from my reality, why not? Then, at 22 years old I asked ‘Momma’, she really couldn't afford it, much less understood it,(but Momma was Momma), for a small loan. I've had those same 3a's since.

It's a real eye-catcher, isn't it Frank?

Yes, the ad is totally authentic, dating from a 1968 issue of

"Stereo Review".

AR advertised heavily throughout the '60s in SR (formerly known as "HiFi Stereo Review"), "High Fidelity" magazine, and "Audio". I have a ton of back issues, and I'll be glad to share some of the more interesting ads.

Here's a 1968 ad for the AR amplifier:

Dear ‘linedrive’, you’ve gotta be kidding?

Sadly, I’ve thrown-out most of my ‘Stereo-Reviews;, ‘Hi-fidelity’ and ‘Audio’, ‘Popular-Science’, ‘Popular-Mechanics’ and literally pounds of information from manufacturers of that period. I used to send for the free mail services from most of those magazines and manufacturers’ and unfortunately that stuff is gone from my collection, although I still have some ‘frozen in time’ at my family’s old house.

It must be said though: you’re, ‘killing-me’!

Sincerely, Frank Marsi

Frank,

That AR-5 ad is 100% the real thing. If you read down through the ad you will see reference to speaker-testing techniques. What AR was doing was mounting the AR-5 (note that the midrange and tweeter drivers were de-activated for this test) flush in the ground so as to get a true "hemisphere," or "half-space," or "2Pi Steradians" or "180-degree solid angle" vantage point from which to measure the woofer's low-frequency performance. This type of mounting "loaded" the speaker properly for accurate low-frequency measurements, and was the standard way in which many serious loudspeaker manufacturers measured woofer performance (see example below from another manufacturer). A woofer's low-frequency response cannot be accurately measured in an anechoic chamber because most, if not all, anechoic chambers (with a few notable exceptions) cease to be "ehco-free" down into the very low frequencies; therefore, outdoor measurements were the rule. Indoor, non-anechoic measurements are now done with more or less satisfactory results using "gaited" measurement techniques that block out the harmful first reflections; however, the "gold standard" is still considered to be the indoor or outdoor anechoic measurement techniques.

Dear Tom Tyson and everyone:

Whoa, now 2 men in front of me, “T.T.“ and ‘linedrive’ ?!

I’m ‘out-gunned’ here and I know it! I’ve worked on the battleships "Iowa" and the "Wisconsin" in ‘1969’ that each had nine- 16 inch guns, 20 double turret 5 inch guns, 40 anti-aircraft guns, and 30 -50 caliber guns, and 6 torpedoes available at any time. I know what I’m feeling here, I know when it’s desperate, and I’m stuck! I’m impressed, and in full trust of any and all information I just know either one of you must have.

I’m going to sleep tonite feeling and knowing that I’m happy to have what I know, and that others are out there for me if I need them, who, I share much with.

Such good feelings, being part of this AR Speaker affection ‘thing’ and hobby, - I’ve become more of a fanatic than ever before. I won’t go into ‘politics’ or ‘world affairs', but each of us knows what we all feel in the 2000’s.

What else can we all have fun with? The past is here upon us almost more than the present and future is!

In reality it says something about the love of music we must all share and what it means to each of us. I’m sure we each have our individual love of particular types and forms of music, however

isn’t it reassuring we all share so much in terms of the need and love of music’s very existence?

We’ll all be speaking together, soon, I’m confident.

Frank Marsi 3-06

P.S. I don’t wanna’ sound too much of anything here. I’m just speaking plainly.

Soundminded, you did know that the "official" beverage at AR was Johnny Walker Black Label, didn't you? I thought that perhaps you had a sip of the official beverage before eulogizing the old AR-5.

I was truely touched to see that AR5's best friend and favorite microphone delivered the eulogy over the unusual open casket graveside ceremony.

"Friends, Romans, Cambridgemen, I come to Praise AR5, not to bury it."

These days I'm strictly a Glenlivit man myself but there was once a time long long ago on a planet in a galaxy far far away....
