I saw these for sale on eBay and decided to take a punt. Very much unknown but seem to be from the XLS family although I wasn't aware of an 8". After a bit of digging I and obviously via the Mission sticker I found they are used in in some Mission active subwoofer.
Fancying trying to build a compact SLOB or just OB I thought these things might be able to be pushed a bit. If only due to the heavy surrounds.
They're were specced by the seller only as 6ohm but this appears to be a DC reading and so they're an 8ohm voice coil. Not very big a VC either...shame!
Magnet is doubled up but not very large diameter. The whole driver is quite small, only 210mm overall diameter. Effective piston about 160mm diameter. Basket is cast aluminium but quite light feeling.
So out of the box I'm a bit unimpressed with the overall sizing for an 8" 'subwoofer'. Maybe has some LT from the plate amp it would have been used with ?
Anyway I did some sweeps on it with DATS. Fs dissapointing at about 52Hz....my RS225s will probably be better! Suspension is very firm so will probably take some power there but the VC being quite small and seems a paper /cardboard type former I'm guessing heat will be an issue before anything else .
