Default info on Wharfedale 12" 3028?

Hi Guys,

I've done some searching and can't find any info about this driver. I doubt it's of any real quality but I got it for free so thought I might be able to use it for a cheap sub project.

Wharfedale 12" Speaker 3028 4 Ohm | eBay

Any info appreciated

Hi,

Cheap sub plate amplifier and 2cuft tuned to 30Hz is
as good as guess as any for a hifi 12" sub with no info.

If that doesn't work out because its not up to much,
you want it tighter, convert it to sealed and stuffed,
that will work as well as its ever going to as sealed.

rgds, sreten.

Thanks sreten,
I have a cheap ported 8 inch sub I was thinking of the taking the amp out of it and using it for the 12".
I was thinking sealed too or maybe just a badly sealed (aperiodic) box might give me the best room to maneuver?

Vented pole and fairly large spacing on the basket between where the spider should be mounted and the top plate suggest that this particular driver might be capable of some decent excursion. I suggest you try to measure its parameters before committing to a design. There are ways to do this manually, if you have access to some basic equipment. It might be worth the effort.

Thanks Brian,
Great website!
Vented pole, interesting
Measuring parameters is not something I've done but it is something I am curious about as is measuring in room response, I think these are issues you tackle naturally as your diy hi fi journey grows. I'll look into it.

Just in case some one else happens by this driver it looks like it's from a wharfedale spc-12. Not a bad subwoofer apparently
