do you think running the speakers as they are now but placing them together in the room would sound ok with one mid out? if i disconnect the driver for safety?.

they have an output on the back where the terminals are for linking another speaker on the same channel and i was considering this running from a mono source so i can use them now without loosing the mid from one channel, in essence having two woofers and tweeters and one mid. would this work? and if it does would it change the impedance of the setup?

thanks Hugh
I don't know what you are going to do really, but I can tell you that if you have a broken driver, it is essential to disconnect the midrange filter altogether. Right now your amp is seeing 16uF in series with 4mH undamped. That will be very bad. Pure resonant load that could fry your amp at high volume.

how would i go about disconnecting the midrange filter if i decide to do that?

honestly havent decided what to do with these for now.
quite fancy building new crossover copying the old one as much as possible to make 2 way for now. dont really want to take old crossovers apart as they are originals far as i know. think i will sort out some parts and use them 2 way for a bit. not going to be high volumes atall so should be ok

Hi H Burch. I am sorry to jump in on your thread but I hoping to ask you a favour. I have the exact same speakers as you that were my dad's pride and joy back in the day and he kindly gave them to me. I've recently had an issue with the woofer cone/driver on one of them and i'm currently desperately searching the internet for a replacement! I was wondering what became of your project and whether there was any chance I could buy the part off you if they aren't in use at the mo. Or if you had any advice towards finding spare parts for this type of speaker. Thanks very much. George
