old speaker resistors

I recently picked up a very large, older speaker with 12 speakers in it all together, 9 mids and 3 tweeters. we took it all apart to see what it was made up to find that all the speakers are wired in pairs of three (so if i disconnect one, it will kill connection to the other 2). we noticed that one mid was blown and the three tweeters were not working due to what we think is a bad resistor wired to them. so my first question is, how do i manage to disconnect the blown speaker and save connection with the other two? and 2nd, since each of the 3 tweeters do work (made a direct speaker wire connection to each) the only logical explanation would be an old resistor correct? i would love to atleast have all of them up and running, but my knowledge on resistors is sub par. Thanks Guys. :)

That's not a resistor, it's a capacitor. Non-polarized capacitors are used as a high pass filter with tweeters. If the value can be read, it will be marked in uF. Just make sure that any replacement is made for use with speaker systems.

I would just leave the non-working group of mid-range speakers disconnected for now. If the speakers have any markings, it might be possible to find a replacement. First, see if you want to put that much money into the speaker system.

ps. This appears to be an old speaker system from an auditorium. As such, it has probably been used at high volumes and may have more problems than just one blown speaker. Don't expect it to have great sound quality either. These types of systems are optimized for high efficiency at mid-range frequencies.
Any chance you can post pictures of the speakers/components. Much easier to diagnose!
