Wow, Olly. That's interesting. Where did you find that?

I see, so its just the crossover board. Let me ask you, do you know what the frequency overlap is supposed to be exactly so we can know if its just the normal activity of the board or if its out of order?

The coil apparently did come loose on one of them. The same problem isn't true of the other. Yet both are suffering from the same midrange blow out. He does have his particular way of testing the frequencies. These guys were recommended on a number of forums because musicians send them their stuff from around the counrty. He's just not familiar

We have the service manual with the schematics of the crossover. This guy is pretty well known in the states, so I trust him so far. Considering I have 2-3 weeks before the drivers get here I have time to discuss it here and see what the forum experts think.

So Martin hooked me up with new midranges that are on their way. The repair fellow at A Brown Soun told me the reason why the mids died was apparently a design flaw in the speakers themselves. There's apparently a small resistor that is sending low end frequencies to the midrange driver on purpose. The old drivers couldn't handle the strain

I'm using the PSW-10 (manual here: specs.retaildeck.com/CACHE/FILE17069.PDF ) I created the cable ends myself with screw plugs I got on ebay. I connected them to the second set of speaker outs on the 2400. On the sub I connected the bare wire to the "Speaker Level Input". The first speaker outs on the 2400 go straight to my Beovox s120s

I just bought a polk audio powered subwoofer to add on to my BM2400 system. I pluged the second channel into the subwoofer with my two main speakers on the first channel. When I switch both channels on the sound quality of the speakers degrades and the sub just sounds like a mess. Also the amp is getting crazy hot. I disconnected the sub. Is there something

Well if you have refurbished replacements I wouldn't mind buying them from you. I'd even be willing to send you the ones I have if they are of any use to you. I don't particularly want to do a lot of foot work involving this.

They said this specific speaker - which he had the documents for and recognized without looking up - was one of the few that was exactly 3" and could be replaced by anything the same size. He also knew that the coils on these specific models can fix themselves after a time and go bad again - which is exactly whats happening as one speaker had this

I just got done doing one of Martin's great recap kits for my crossovers but my midranges are still distorting. I called the B&O service headquarters in Chicago and they said the coils are shot. They also said any 3" 8ohm midrange will do as a replacement, but I'm having trouble finding one that will fit the cabinet just right. The
