[quote user="Chrisreunion"] Chasepoes, have you done any mod to the treble filter section after replacing the tweeter itself? [...][/quote] Yes I have. I've shorted a resisitor (I think it was R3, have to check that) It's the only resistor in the high-section that is placed in series with the tweeter. This brightens the overall sound

What I do know for sure is that if you order a new driver from B&O, you get a HEAS unit. I'm currently in the proces of fitting a pair of high quality metal-dome tweeters in the Penta's, which is surprisingly easy. I'm now calculating the modifications I have to make to the cross-over. So far (no mods to the filter) the high's are

As far as I know, the original OEM manufacturer used to be HEAS. My Penta's have unit's with exactly the same label on the back. It's identical in every aspect, except for the brand name, which is ITT in my case.

[quote user="tournedos"] resistance between different connectors is not constant. I'm not claiming that would be audible either, measurable just perhaps... [/quote] Ok. I thought the soldering was done to improve the sound. Simply disconnecting and reconnecting them again will make them have perfect contact again. [quote user="tournedos"

[quote user="Beobuddy"] How did/would you do that? All the penta display's get there power (10V AC, type mkI, II, III) through the powerlink, which comes from the main transformer. Imho a wrong suggestion. [/quote] What I meant was: If you connect the original display's to the connector found behind the plastic panel (situated inbetween

Second hand display's are few and far between. They can be ordered at B&O, but it'll cost you. I've never worked with the Ridax display's, so I can't comment on them, nor on how easy or hard it is to fit them into the Penta's. Regarding your other steps in upgrading the Penta's, I've got a very different opninion

But he already found some display's if I'm not mistaken. In reply to Dillen. Realligning the spider is not necessary with these units, 98 times out of a 100 times. The spider in these units is strong enough to hold the conus in place, even without a surround. I've refurbished hundreds of speakers (Used to work at a speaker\stereo repair

[quote user="Chrisreunion"] Great, thanks for the advise and the detailed pictures! I found on Internet a pair of BeoLab 200 at a reasonable price, is it possible to simply screw them at the bottom of a BeoVox, and make the BeoVox become a true BeoLab Penta with proper Powerlink connections? Or is it not so easy to do...? [/quote] Fitting

Yes this feeds directly to the display. Behind the plastic front (inbetween the two front grills) you'll find the other end, with a connector attached. If you can find the original LCD display's, you can connect them directly to that connector and mount them behind the translucent front. Plug the bottom connector directly in a powerlink and

I recently refurbished a set of Penta's for a client, who insisted on having the mid-units replaced, instead of refoaming. So I replaced all 8 units with new ones (ordered directly from B&O). After finishing the job, I was able to compare a refoamed Penta, against the replaced Penta. I (and my colleaques) could not hear any difference between
