These are Cube3 not Cube2 so 4 inch Dalesfords. The Bextrene cones will be flobby by now. I have discovered that Bextrene has a life and lose stiffness and strength after 20 years or so.

New drivers I use now are listed in the DIY section. It is up to you, you may like as is, but PM Kazim who made the change on his old Cube1 if you want to know about it.

I am trying to help and stop disappointment as I did with Shane, why do you think he sold them.

Thanks for the info, Doc. I'll see what state the units are in when the Cubes arrive, Shane did say that some refurbishing work had been done. Should new drivers be needed, then I know where to look.

Carry on take no bloody notice of me, why should I try to help :roll: Did you ask Shane what he meant by refurbishing, are they standard as built.

I make £10 profit each for doping those drivers and selling them, I am obviously desperate for the sale :naughty:

Doc: in my enthusiasm I didn't ask and took the speakers in good faith. I did see from the photo's Shane posted that one of the tweeters had needed replacing. That anything should be done to the bass/mid driver was not something that I considered.

Of course I would dearly like to have these Cube 3's singing perfectly and will be more than glad for all information/experience/wisdom that you can give me. But they're not here yet so I just don't know.

But Doc, you had better put one of your sets of doped drivers to one side for me - there is a very good chance that I will need it.

They don't fit as exact replacement, if I was doing it I would glue the new drivers in with Bison kit and just bloc the old screw holes. If tweeters are not the same as each other that is not a good idea. I wouldn't spend £50 a time on the Visitons unless you really want to. we can find a cheaper set for this job. Crossover will not need changing unless it has been ferked with in this so called refurbishment. I really do not understand how they could have been refurbished if I didn't do it.

No need for steel plate unless you really want to as the thick MDF in a cube structure has very little of the problems steel plate removes.
