KLH Model One and Model 5 Speakers?

Thanks guys, I'm really looking forward to these.

I wrote and asked Kelly the dimensions, Ron, and I did think of you, so thanks, we'll see. Good of you to offer and good excuse to visit again.

Thanks for the kudos on my Valiant, thedelihaus, I really like the A-body vintage Mopars.

Hey, if the cord isn't completely severed, there is always hope. My dad broke his back 3 times rioting murder-cycles :yikes: and has absolutely no problems. This is my 17th year; there is no question as to my status. I've seen them come in totally paralyzed, and walk out. Sometimes it takes years; keep up the physical therapy they say. You didn't say how long since your accident. Good luck to you, I hope you have access to good help. :thmbsp:

These are truly very rare. The Model 1 was a woofer in a cabinet with a cavity with the dimensions for a JansZen tweeter array and later they made a KLH array to the dimension as an alternative. The KLH array is very rare as most opted for the JansZen. Value on these is really up to the buyer and seller as there are so few that were made before the Model 12 and soon after the Model 5 came out and killed it off. KLH opted to license the design of the Nine from Art and Art produced his hybrids.

I have seen a few of the Model 1s on eBay and 1 complete 1/5 system. It is a shame you are so far away or I'd do some swaps for them.

The important thing is to keep them together and not separate them nor part them out. May not have the dollar value but a true collectable.

I suspect the bass module could stand some bracing and the x-over some new caps to get them up and running right.
 
Shhh... I don't want Kelly to change his mind. Great info, Brian, I know they are special, but not the details you point out. I'll re-cap it, if necessary. Should be hearing from him soon...
 
Damn sure got em!

Well guys, I got these big speaks from Kelly. :banana:
They look and sound great. Driving the Model 1's with one SANSUI BA-2000, and the Model 5's with another of the same. I am amazed at how they soak up the 110W (by the meter, at 8Ω... whatever that equals at 16Ω?). With a bit of powered <140 kHz sub they are comparable to the best I have heard -- and they are ~50 years old! Of course my ears are nearly the same age so.....

Brian, I don't know how a guy would do this without destroying the cabinets; there are no screws, they are glued and completely sealed. The drivers may be removable, but the grills aren't. There is a bit of resonation that bracing may reduce... but that might be my ears or the amps or WKW. Surely the x-overs need help but..... :scratch2:
 
Congrats on getting them. Be careful as to the power. Remember these were designed LONG before high powered amps were out and for a community that primarily listened to classical, chamber and vocals at polite levels so easy to burn out the drivers. Also, they are old and age should be respected.

As for getting to the x-over; its been so many years since I had my hands on a set of these I am not sure how to get into them. 1st look closely around the perimeter of the grill and see if either tacks or staples can be seen. The were made in a period when many grills were inserted into the cabinet and then the baffle so the box has to be opened to get the grill out. So they could be either tacked on or not removable externally. I think some of the early KLH 6 owners can advise as to hoow to get to the x-over when you can not remove the woofer (for whatever reason) as the woofer on the early 6 is bonded to the baffle.

Good luck with then and thank you for saving a truly great piece of audio history. These preceded Art's hybrids AFAIK and were specifically made to accept his array. The AR1w was not designed with his array as a design criteria so hence, I think the KLH 1 with the JansZen may have been the first designed as such hybrid dynamic woofer / electrostatic stereo speaker. The fact that you have the even more rare 5 addon system make you set even more exclusive and interesting.

I hear you Brian. The low-efficiency design of these and working the amps at 16Ω makes the large and sensitive meters show the jumps to high levels very quickly, even at low volumes. The needles bounce from 20-70W at one setting; 50-110W further up the scale; max w/o clipping is pinned from 90-redline. I only went about half-volume, and it didn't max the speakers out, but don't have reason to drive them that hard again.

It is probably fortunate for them that my hands don't work. Before I broke my neck, I worked on an early model KLH that was glued together. The back didn't come off, and the woofer wasn't very cooperative.

I don't hear any flaws, so will keep them as-is, listened to through sheets, in my living room. I live alone and actually spend little time there now. Thanks for the background info... any more, sites etc.? I have found little on these.

Thanks, Matt :thmbsp:
 
Matt, I'm looking forward to hearing these new speakers someday soon. How are the other smaller KLH's you also recently bought?
 
As an afterthought. I suspect the 5 module was carefully tuned to at the x-over point and to the 1 as it had to compete against the JansZen module and at the time the JansZen was considered as THE ULTIMATE STANDARD. While companies try to get the crossovers and integration right, few have to design to compete against its own design using the same component as its competition. Sort of odd sentence but think you can get the jist.
 
Ron, c'mon up, it would be nice to get an opinion from your ears. I will confess to a ringing and drop in hearing at certain frequencies, diagnosed in '89 :yikes: prior to my discharge from the Army. Working on tank engines for them 13 years had its affects, especially the later gas turbine M1.

Sad to say, the KLH Sixes have not arrived yet, 15 days after the auction's end. The seller assures me that they are on the way, but I am beginning to have my doubts. Time to contact him via phone... don't want to wait too long to file a claim.
I hate that! :twak:

Brian, I did read somewhere that the JansZen's really make the Model One come alive and that Model Five couldn't compete. I have no complaints with the latter, but acquiring the lot of them would be right special. I didn't understand which speaker you are referring to as being electrostatic? :scratch2:
 
The sound of the 2 modules whould be different but that is not the fault of KLH design. The electrostatic is a detail animal and has the prefect (or near it) level of air. It's big advantage and at the same time disadvantage for its use in a hybrid config is the low levels of distortion that approach .05% whereas a dynamic driver can easily be 5% at normal listening levels or even higher. KLH's challenge was to use its drivers in a manner that would give the speaker a cohesive refined sound that mate with the woofer. The sound is different and will be more laid back and the highs not as extended with less detail but should be enticing and draw you in to listen to the music. As to if it could compete, well tha t is a matter of tastes. I have been a proponemt of electrostatics from the time I heard the Quad ESL just after it was introduced and later the JansZens, especially the KLH Nines that a few here now are enjoying ( a personal victory for the cause) but I have not problem listening to a well made dynamic system though it does take awhile to reacclimate myself after listening to electrostatics. Take my 2 pair of Bozaks and the Wharfedales. In my heart and mind I know they are not up there with the Nines in absolute terms but I love their sound and when listening to any of them never think about what is compromised.

I got it, Brian, with a little research. I see some JansZens on eBay... they sure are expensive! Might be in the best way for me to get into electrostatics though. I wonder how well they survive and how to fix them.

Thanks again for the info, Matt :thmbsp:

Oh yeah, the Sixes are on the way, the guy assures me. Threw his back out he said.
 
The Series I panels are pretty bulletproof but will tend to arc if there is humidity. The later Series II are less subject to arcing and will hold together with much more power pumping through them.

The Series I power supplies are quite simple and easy to rebuild if necessary. The later Series II has several variation of power supplies but generally are more complex than the Series I. Sereis I can need caps and possibly a replacement for the selenium if early enough. In the Series II, simply more caps. Occasionally, if someone thies running them with caps shot, it can take out the power transformer but these are pretty generic and can be subbed out. The Series 1 units are what were mated with the Model 1. Not sure if the Series II had the same cabinet dimensions.

Yes, the addon arrays from the company are really sought after today and where back then they were only for the well off or audio insane today more can afford them and are willing to pay for what was an ultimate upper end back then.
 
Hmmm... interesting, I would love to audition a pair, but for now will have to stick with the KLH Model Five. Do you know what's inside it for drivers? (My hands don't work...)

Thanks for the info, Brian :thmbsp:
 
Brian, one last note on the JansZens. Have you seen the JansZen Loudspeaker, Ltd site? Very informative, with resources and history. Check it out here.

Hi SuiDog! What did they say was wrong with your hearing? I also experience the same thing and I'm sure it's damage that was caused by my "car stereo years" as a young guy! I've done a little research and came up with something called tinitus but not sure if that's exactly what's going on....

BTW - I was the one that started this thread wondering about the values of the KLH's. I'm kickin' myself for not jumpin' on these but I'm glad they went to a good home! :)
