Thank you!

So you tucked them in, but just a little bit 🙂

I’ll try.

@Glitch can you perhaps take a photo of your grills from the inside. I don’t know what to do with the tape and the cloth around the clips on the frame. If I cut around them, the cloth pulls comes out because of the tension. If I snuck them in the clip, then it can’t move properly to be attached to the speaker. These are the grills from hell :)))

You just caught me trying to get rid of the glue applied by previous owner 🙂

I have also prepared the glue :)))

Well, I guess I’ll get rid of it, and starting looking for the tape.

Thank you for the advice!

Ok, got it. Working now. And we have an overwhelming improvement in sound 🙂

Now I’m moving on to polishing and changing grill cloth, which is going to be a great pleasure now that I know they are working.

Of course, in the near future, I plan to refresh crossovers, and check what that guy did with amps.

Thank you all very much for your help, this is a great community and I’m happy that I joined. We will certainly talk more 🙂

Thank you Glitch, I think at this point I need to try to correctly wire them. Beobuddy’s explanation is a bit confusing at first reading, so I’m now trying to understand what is the correct position for each wire.

If correct wiring doesn’t help, I’ll take out crossovers and send pictures.

[NickNS]

Can you please re-iterate once again the correct wiring 🙂 ?

[NickNS]

Ok, I’ll try what you said. It’s still possible that they were incorrectly wired after re-foaming.

Hi everyone,

Thank you once again for taking the time to help me with this.

Here are the results after taking midrange board off one of the speakers.

First I checked polarisation with voltmeter, it was correct on two drivers and incorrect on other two.

Disregarding polarisation at this point, the real result is this – when connected to Penta, neither one of midrange drivers is working at all. When connected directly to the amp, all four work as they should. Tweeter works fine when connected to speaker.

So, I suppose the issue has to be somewhere in the tower.

If you have any further suggestions on my next step, I’m here to listen 🙂

Thank you both so much for the ideas and suggestions!

Let me reply ‘shortly’.

I didn’t have the opportunity to hear them prior to purchase, I just took a leap of faith. Not a smart move, I know, but what’s done is done.

I can not test Beolab amps with S45.2 because I gave them in exchange to the guy who sold me Pentas (plus some money). But, I did take the amp off and connected Beomaster directly to the speakers, and the sound did not change (BeoVOX test). Therefore, I assume I can disregard the option that amps are causing this issue, at least for now. Also, I didn’t have a feeling that seller actually new what was done with the amps, he is the dealer of used audio equipment and has ‘his service guy’, and he seamed like the person who doesn’t get involved much in the ‘service’ part.

Placement of the speakers is in the corners, 40 cm from each wall, about 3 1/2 meters from each other and about 3 meters from me. And I’ve tried all of the settings provided on the speakers, starting with factory suggestions from manual, and then combining different levels of sensitivity and bass, as well as Power Mode.

So, following your suggestions, I plan to check polarity of midrange drivers tomorrow and test them with frequency sweep connected directly to the amp. On that occasion, I will take some pictures and post them along with results. If I don’t find any faults that way, I will consider re-capping the crossovers.

At some later point, I do plan to take the amps to my service guy who already did an excellent job with my Beomaster 5000. I want them checked, measured and serviced if necessary, even if I find that something else is causing current issue.

Thanks again to both of you, hopefully I’ll post first results and pictures tomorrow.
