  1. The tighter bass is what I would expect as a result of sealing what is essentially an air leak in an acoustic suspension loudspeaker. The symptom itself (woofer pumping) indicates that your cartridge and tonearm may not be well-matched. The woofer excursions almost certainly represent flexing of your cartidge's cantiler, amplified. As to the doping of the surrounds, I wish somebody could tell us what CTS used. I have several of their woofer from the same time period as the KLH's. They have thin cloth half-roll surrounds with a thin coating of something that is still tacky, highly flexible, and airtight after 40 years!
  2. Hello. The negative (often black) terminal on your receiver or amp should be connected to the 'ground' screw on the KLH speaker. The positive terminal (often red) terminal on your amp should be connected to the '8 Ohms' terminal. They're great speakers by the way.
  3. ADC (New Milford CT) used mostly CTS's, and Avid (Providence RI) used some also.
  4. I'm not familiar with your KLH 15, but the turntable is different (both the color and the tonearm) from the Garrards that were used in the more common KLH compact stereos.

    AVID History

    Oh yeah, I remember his name being somewhat revered back in the day, probably in relation to the Scott speakers of the sixties or early seventies. Seems to me he died in the seventies, "at the end" as you put it. I think his name was invoked in order to give the Avid name some credibility at its outset. On further thought, I think I learned of his death while looking online at an old issue of the Boston Audio Society newsletter.
  6. ...... I took the headshell off and the needle did not appear to be too good. It looks like the original cartridge. It says "ffss 4" on the front of it and on the bottom it says in handwritten "AE 9752". It also says British Patents ####, made in England. It looks like there is a little noose that holds the needle in place, weird. The headshell says "ortofon" on the top if it........... Mike: Ortofon used an "FF" prefix on some of their model numbers. And they did sometimes partner with European turntable makers. But the 'made in England' part is confusing; I only know them to be a Danish concern. -HarmonY

I hope that you don't mind my editing; I tried to save the salient points. Back in the early seventies, I remember several companies offered 'compact' stereos, a la KLH. Many of them had turntables that were superior to the Garrards that KLH used. Scott, Kenwood, and some others made units that had a Dual, a P-E, or a Miracord turnable built in. Scotts of course could be bought with Scott speakers, and in other cases people would buy the speakers separately, meaning they got KLH's, Dynaco's, etc.
  8. >Never heard of KLH Research Ten speakers. What are they? I vaguely remember some advertising. Probably from the mid- or late-seventies; the impression I got was that KLH was trying to modernize the look of their speakers (perhaps this series had wrap-around grille-cloths, and wood caps on the top and bottom?). But I've never seen or heard them.

Some of the Canadian brands were doing a good job of filling that void, though I've lost track of what they've been doing of late. Ten years ago, PSB, Paradigm, Energy, and a couple others were making good basic 2-ways. I like to think that they are (were?) the next step in the progression.

The Brentwood model was, I believe, also known as the 303A (no X). I've never seen a pair in person, but I once owned a pair of the successor, which was known as the 303AX (similar in size to a KLH model 6). They were a nice speaker, but the earlier model, the Brentwood aka 303A, was said to use higher quality drivers. The 303AX used a nice 10" woofer, and a cone tweeter which I would describe as rather ordinary. The earlier Brentwood used a dome tweeter, possibly KEF, and I'm under the impression that the woofer was 8" rather than 10. The 404's that you mention were a 6" (or 6 and 1/2") two way, and were on the market at the same time as the 303A Brentwoods. They were superceded by the 404A's, which ran concurrently with the 303AX's. Confused yet? My family still has a pair of 404A's. I wish I had my 303AX's back. I stupidly handed them off to a friend years ago.

Still would like >to know if anyone has had any experience with this machine - >good or bad. Hi Matt, Sorry this reply is late but I just signed up. Yes, the smaller model that I've seen was called the Forty-One. A friend had one in the early 70's and when it was about a year old the sound quality went to pot. Cleaning the tape path didn't help; I took it to a friend who was a computer tech and he tweaked a couple pots inside... but a year or two later the machine failed in some other way, and by then its owner had lost interest.
