So I have recently acquired a gaggle of three HR824's which are, despite some serious cosmetic issues working and putting out sound.
They came as a working pair and a spare with the main woofer missing.
They came from an events company(stages, sound systems, live events etc).
I initially thought that they were good, both the complete ones powered on and sound great but lack any serious bass but i put this down to the woofers not having dust caps and hence the sealed cabinets not being airtight, on further inspection one of the drivers rubber surround has perished in parts, I ordered some 8" rubber surrounds that said 196mmOD(from amazon) but were a few mm short and don't fit.
I thought it best to remove the woofer and get a good look at the cabinets, unfortunately the previous owner has painted all the boxes with a thick black gloss paint and by the looks of it put the(woofer/tweeter) surround back into the cavity before the paint was dry, anyways I got it out with some considerable force and it made a right mess of the cabinet, it is still usable but is now taken back to the MDF.
I really would like to keep and maybe refurbish these speakers as the amps/tweeters/passive radiators are all good, in fact they are in fantastic condition given they are more than twenty years old.
So what to do with the driver, glue it and hope the rest of it does not give out anytime soon, take the rubber surround off and put a new one on or replace the driver?
The driver is a funny size, Mackie say 8.75" but it is really just an 8", the OD is 227mm, screw hole is 218mm the rubber surround is 196mm.
Oh what to do, if i can't find a replacement driver or rubber surround I do still have the amps which are very tasty units and could be bolted to the back of a good hifi speaker box or even build a box in the same fashion as the Mackie box.
I will post up some pics later of when I took it apart.
All suggestions welcome, thanks.
