Dear all, I'm considering redamping my cf-3 rev 3 with good quality foam. Can you advise me? What about this type of foam? https://www.toutlehautparleur.com/laine-d-amortissement-15-mm-coton-100-x-73-cm-speciale-acoustique-avec-face-adhesive.html And where should I apply it? On every internal faces? The original foam look cheap. And I LOVE my speakers so if I can upgrade it... Thanks for your help!

Dave you was absolutely right! 2 woofers on the same cabinet with dust cap unglued! Now I need advices on how to glue. I have to completely disassemble the dust cap or can I just add glue where it's needed (with a toothpick for example)?
-
Thanks Dave, I will check tonight when kids will sleep !
-
Thanks Dave You speak about the dust cap but I was thinking my problem concern the plastic part around the woofer. Is it possible? I can clearly hear a vibration on high-volume bass sounds. It's really annoying ++

Dear all! A few days ago, I upgraded my installation and bought a DAC (Gustard X20U). What a, improvement!! Whaou! So impressive! But, with this quality I also noticed that one of my woofer is making a strange noise when playing music with high low frequency. Something is vibrating/resonating and I can't find what. I have the feeling that the plastic spacer that surrounds the woofer vibrates. Do you know what can it be? I have also the same noise when the woofer ii outside the cabinet (unscrew and put on the ground).

not me sorry. But It should be easy to read caps and resistors values on your actual crossover.

Hello Moray James In the past you sent a zip file with two differents crossover. After some research, it looks like it was a rev1 and a rev3 crossover. Can you confirm? Again, do you think I can modify my actual rev3 crossover to have a rev1 version despite my differents woofers (model 1030 instead of 1022) ?
-
@Dave this is strange because we don't have the exact same schematic. It's pretty close but... (Mine is on the left, yours on the right) When I look at the schematic Moray James sent, it looks like I have the exact same component as CF3-B schematic. You have component from rev1 and rev3 so I think that you have a rev2 crossover. Can you post you Low Frequency crossover part to check the difference with other revisions? @Moray James Do you think I can modify my actual crossover to have the same crossover (with my actual woofers) as the rev1 version? Thanks again for you help!

So today, I disassembled one of my cabinet totally. Actually one of my cabinet had the back unglued so it was easy to make some bracing! I was very astoniched to see that my two cabinet was not build the same way. one is poorly built compared to another. This is completely sloppy! On the bad one, the screws are screwed awry, no paper gasket but a really thin foam between woofer and cabinet, the damping foam in the enclosure is badly cut... The builder did a crappy job! Here are some photos of the cabinet I am bracing (this one was well built) For making a good bracing in this cabinet, what are the secrets? Thanks again for your help!

Ok thanks all, Next time I will try to cut the dynamat in one piece. by this way, It will be faster and easier to put on the woofer. Then I will brace my cabinet. I have a lot of wood tools (purchased for the construction of my cinema room 2 years ago) and I think I can make something good. My idea is also to put a veneer on the cabinet to make it WAF compatible
-
Ok so the first woofer is finish, what do you think? Did I forgot something? As you said, the speaker wasn't glued but there was a kind of foam around it that I damaged during disassembly. I do not think it's serious but it must certainly be replaced to get it right?

Can't stop damping Bob Crites can remake my crossover with better capacitors but I have to think if I want to take the risk of shipping my filter... I can do it by my own if I really want but is there a big improvement after that? I also have to carefully choose my caps because it can be better or worse... ++

I've sent a message to Bob Crites to know what he can do on my CF-3's filters.
