@timlub Hey Tim. I definitely hear what you are saying and totally makes 💯 sense. I really would like to get the most performance out of those speakers and I know totally agree what u are saying about only replacing the necessary parts and caps. Maybe some better wiring too ? I would really love for you to do the work on these crossovers for me if u would like to take on the job. I appreciate your time everything you said to explain all of this for me. And I’m sure I’m making the right decision now not buying those crossovers from eBay. And he also sent me a pic of the new crossovers and they look totally different with a lot less parts and caps. And it looks like they are mounted on a piece of plywood and not a circuit board. If they are. I forget when I installed them when I got my speakers.
Ferrofluid
Hey guys. So I have been texting someone from Germany I met online as he also has a pair of B&W 800 Matrix speakers. He mentioned that he treats his tweeters every so many years with Ferro fluid. It was kinda hard to actually text about it online with someone I just met from another county. I did google it and looked on utube for some videos and there are some. It’s seems it should be done about every 10 years or so. And u actually have to take the tweeter out of the cabinet disassemble / remove the voice coil clean out the old Ferro fluid and add new Ferro fluid. It’s seems to be some kind of a magnetic liquid used in speakers especially tweeters for better clearer sound, highs, voices etc. It really looks like a job for the experienced in rebuilding speakers. Has anyone heard of this or had it done ? I’d really love to know from folks who had experience with this. My speakers are from the 90s and even though they still sound phenomenal I’d really like to know more about this. I do plan on keeping my speakers for the long term. Thanks to all in advance.

My only FF experience was when I rebuilt my Boston a400’s. It took me maybe 10 min per tweeter . One had tarry looking FF, the other looked fine - go figure. I replaced both anyhow. I used a meter ( $20 off Amazon ) to check capacitance of the caps and a few were off so I replaced all with film caps. You should get meter and check them before replacing . I have a 40 year old set of ads 1230’s and and 42 year set of GNP Valkeryies and both had all caps in spec so why replace them? I’ll read posts of ADS owners sending their crossovers to Richard So to be recapped but why bother if they are fine? Btw, a good track to show off how good your speakers are is the song by the cars called “Drive”. If they are revealing, after the second stanza , you’ll hear bongos playing a counter melody in the back ground of the “duh duhs”. |
@katman Thank u for your reply. I will certainly think about that and possibly I can have my service tech come by and check out the crossovers. I have said that about the Cars song She’s Dangerous. The drums in that song sound phenomenal on my speakers. |
No need for a tech, just order a capacitance meter off Amazon $20, put either lead on either side of each cap and see if the number on the meter is with 10% of the number on the cap. It’s really that simple and you can do both crossovers in 15 min, no chance of damaging anything . In the time it takes to call someone up and explain what you want you can have one done. But hey, it’s your call. |
