What! No Wake???
Darko, the problem is usually with the control pot. Below is what a 40 year old pot looks like disassembled. As you can see, corrosion is everywhere.
You best bet is to by-pass the pot completely. This will cause a slight boost to the high frequencies, but when you look at how the AR-6 normally "rolls off", that slight boost can actually help a bit.
Hope this helps ...

Jerry

Hello Jerry,
Oh, did I dismissed something
Hmm.. the Frequency Diagramm is very informative.
Thank You Jerry !
Have right now mount the Bassdriver back,
after pulling out the imense Amout of yellow Glasswoll.
I have a lot of nice Speakers, but only this new Babys
take sooomuch Dampingmaterial Inside!?
The Switch is overall glued with some Wax or similar Stuff.
By side, two Resistors are soldered. Pretty nice Job, they done.
I measured also the 24uF/50V Lytic on the Bassdriverconnectors.
Was 34uF. Not bad. Off course, ESR may be away.
On the Network "Platen", is a huge blue Sprague installed too.
I cant read the Value, but tis Baby rocks definetly.
Funny is, I can read some Letters, like "...ampilytics".
Ok, so far, so good.
I let them in Original Shape and Tommorow, I will play with some Tannoy SRM12B ( Little Red Monitor ).
ps: I think, a Yamaha CR-620, or CR-820 may harmonize with the AR-6 ?
Some SS Amps like Yamaha have very punchy, piercing High's.
Lets cook ...!
Have a very nice Week, Jerry
Cheers,
Darko

Darko, the AR speakers have a "darker" sound than most ported speakers. The top is rolled off with purpose, to recreate more faithfully the sound of live musical performances. I find the AR "sound" to be one of the least fatiguing speakers I've ever heard.
They will not make you go "WOW" at first like many splashier speakers do, but the sound will grow on you over time if you give it a chance!

Hmmm, I've never seen a switch on any of the early AR's. The AR-LST's have a 6 position switch.
Darko, take a look at the Increase position of the switch. My guess is in this position NO resistor is selected. If that is the case, try by-passing the switch as it may have the same corrosion problem as the pots.

Jerry,

Ozmo,
Thank You for the Input. Its like, You describe.
Its a Non-Fatique Speaker System. The WAF is also increased ;-)
The Bassdriver have very-new Surrounds. They need maybe
some Time to Play-In. I like the massive superior Datail Works.
These are Quality Speakers, sold in the 70ies for 82$US (Oiled Walnut Version).
I think, maybe they was constructed for Regals to put-them in a Encloser
Ambiente. Its a Flip-around-System. You can rotate from vertical to horizontal Position and vice-versa. The AR-6 Logo flip also in any Rotation.
Very good Craftmanswork, the Guys of AR have done!
You Guys, have Fun and enyoy every Second in Your Life
by doing, what makes YOU happy -> Listen to the Music!

There are no switches on AR-6. Your speakers' integrity have been breached at some point!
I will make this important comment in respects to AR-6:
This is one of the only 'earlier' units that is not veiled/muted in the highs. It actually has a considerably bright and upfront high. This speaker model was designed for rock music; and as such, it is brighter sounding than other AR's of the same era.
All in all, AR-6 is a great smaller-type mid-sized bookshelf that has terrific bass and clear crisp highs. The AR-6 is the only pre-Teledyne era AR that approaches the West Coast sound. It is unique; and as such, it should be a part of any serious vintage AR afficionado's collection.
Cheers
PS. I would NEVER sell mine

FWIW, my AR6 has a pot, not a switch. The pot is marked "Increase--Decrease"

New surrounds on the woofer will take a while to loosen up - over the next few weeks you should hear increasing bass output . My AR woofers kept extending for over a month after the new surrounds were installed.
Definitely need to figure out how the crossover network has been changed and get a proper replacement pot in there - that will go a long way towards giving you the right "balance" between the woofer and the tweeter. I'd guess that you have still not heard how these speakers can truly sound!

Well, the mystery of why darko has has a switch and no potentiometer is solved.
Darko has the European version of the AR-6!
Very nice pics, darko!! Those cabinets are beautiful!!
Now to get that tweeter working! Looks like you have a foam gasket on the woofer, so just unscrew and remove.
darko, can you take a picture of the switch and xover? Chances are the switch is enclosed so it won't be easy to clean, but by all means try to clean.
My guess is in the "increase" position, the switch by-passes some resistors. Once we see the switch, we might be able to come up with an easy way to by-pass. Ideally, darko, you should remove and clean it, but sometimes the corrosion is so bad ... it's impossible.

Jerry

Beautiful speakers, Darko! I love the European cabinet styling......very classy. I have the European versions of the AR3a and AR5.......but they both have pots. If you ever want to part with those 6's, please keep me in mind.

EDIT: Oops! Strike that, I wasn't aware of the "European version." Onplane, what do you make of the paperwork referencing the ability to disconnect the tweeters, but the cabinet only having two binding posts? Do you think it is just an oversight?
onplane
What! No Wake???
judge, I think you are correct that AR just used one set of paperwork for all models and just changed the model number.
Did you notice the velcro to hold the grills in place? That looks like it might be original.
Anyhow, the European cabinets are beautiful!!

First,
I will say Thank You to All, fo rthe nice and informative comments
The Switch is only a Switch, no more -> can be replace with better one, in the same Size and same Look, no Problemo.
Onplane,
The Original was in the same Highment and I use again the same Hardpaper-Gaskets, to glue the new Sourrounds on it. Under the Chassis-Edge, is indeed a soft, grey Foam. Its important to be there for a good Air-Isolation ( Suspension ? ).
Iff I try to push the Membrane-Cone In/Back,(gently and centered ),
I can feel the Strenght in compressing Air in a Box. Tight!
AND:
I compare with a Marantz 2270 2 Pairs of Speakers.
- Tannoy, Little Red Monitor ( SRM12B )
- Acoustic Research, AR-6 ( EU-Version? )
PLUS:
Tannoy is a bit more unforgiving and present the whole Range, but no enough
Deep. Have used Stand with ~4 Inch in high. Better than directly on the Floor.
The Optimum should be between 35-45". ( for my own use ).
The Adjustment Pots are very fine and good doing the Job.
MINUS:
- The Sweet Listening Point is pretty small. One feet left or right, You loose.
The Deep is missing at normal Volume. I have to take the "Loudness" Function.
- Its clean and bright sounding, without the Grills.
AR-6:
PLUS:
- Reel Live Feeling of the Image. Dezent and discret. Never too busy.
- Little, small Cabinet.
- Very good Positioning in Corners ~ 1m over the Floor.
- Good WAF, between "... oh so little and nice" and "...is there Anybody in the Kitchen??" ( livesounding Atmosphere )
MINUS:
- Have only one Pair ;-))
- Hard to find in Switzerland in this good Shape.
BTW: My Refoamjob was a Pleasure
First Time, I not cut the Dustcone away. Only from 8:00 - 16:00 O-Clock.
I let a bit Paper alone.Then moisture the Bending-Zone with warm Water. Then bend slowly up, until the VC is present. Shims? YES! Have tryed 4 Visitcards, before I found the right Thickness. Then after the Sourround was drying good, I bend back the Dustcone and glued back, exactly in the same Position. For keepin down, I use a Easter-Egg of Stone, that fit perfect in Diameter Imagine that Picture
ps: I wish, I better understand American Language, to make the Prozess clearer and more plaisant for You. Maybe after the Summer_07?
Anyway - The AR-6 are very lovely, little Keepers!
Have a nice Weekend,
Darko

The effect of filling a sealed cabinet with damping material is to make it appear 1.4x larger in volume, thus a lower resonant frequency and better bass.
Turn up the treble and put your ear close to the tweeter itself to verify if it has any output.
