Wharfedale Unit 5 Speakers

[cdbirch]

I have some old Wharfedale Unit 5 speakers in home made cabinets dating from about 1970. I have lost the specifications and wondered if anyone knows about them.

I think these were driver or driver+baffle kit similar to the ready built Wharfedale models of the time -- Linton, Denton, Dovedale - start by looking for anything on those because they are a lot less rare than surviving kits, I suspect.

They weren't great speakers by the way -- I quickly upgraded to KEF and only ever tried Leak/Wharfedale again when given some while working on their advertising account 5 years later -- still didn't like them.

I built a pair in '70 or '71 and found the bass exceptional. I've since built better but want to use the 2 woofers as a sub-woofer and need the inside cabinet dimensions so I don't blow them. I'd love a scan of the instructions.

Hi John, Do you still have the assembly instructions, i have managed to get the dimensions from a friend who has a pair of these but it would be nice to have a copy of the original paperwork you got with them.
