Question 1970s Rola Plessey FR driver

Hi,
Does anyone know anything about these full range drivers?

They're a Rola Plessey 8inch, model C8MX00 and my googling tells me they're a 1970s Australian driver, but not much more. I'd love some more specs on them if anyone knows anything.

Also, does anyone recognize the logo on the cabinets (see the picture)?

I found these speakers on the hard rubbish (kerbside rubbish collection) but the drivers look to be in good condition. The box was a smallish vented box. Of course they're probably not as good as the pair of B&W DM330 speakers I found on the hard rubbish a few months ago

Good find. I'll take them if you can't find a use for them !

They were a pretty good driver for the time, running fullrange from 45-50Hz up to 12K with not too many peaks and troughs in the response.

Do they work?

Default Re:C8MX

I have a few NOS C8MXs and some other similar ones from 70s, (can't recall exact model, but may be 8PX???). In the 70s I built a similar slimline enclosure as described in Electronics Australia mag. It had a series of slots on the back of the enclosure and was lined with 1/2" felt--sortof an aperiodic vent. I remember it sounding OK, but that may be selective memory ;-) I would appreciate any plans for ROLA speakers or pointers to where I might find them as I am interested in full-range drivers, perhaps with helper tweeter on OB or aperiodic box. TIA

Regards

Ozziozzi

Hey simply, that info sheet is a good one. Were there any more like that around, or just the one?

I might have to run a search to see if there's any more like that. Love the twin slot version...

Thank you Richard for your kind offer to scan and share plans. I sent you an email via diyAudio with my home email address--hope it got through to you. Re: 70's speakers, Magnavox 8WRs are another good type to grab if you see them.

Cheers Ian
