Spec sheet here: https://forums.melaudia.net/attachment.php?aid=6183
They’re heavy beasts at 14 kgs each and are rated to 200 W at 250 Hz (!) so would be ideal for crazy large horns (e.g. W.E/SATO).
Both measure 5.3 ohms and play fine when swept from 200 Hz upwards. No buzzes etc.
In excellent condition, except that one driver is missing its label and this one has some hairline cracks and some missing paint on one side (see pics). Purely cosmetic.
I’m based in Dublin and cash-on-collection most welcome, but happy to ship (preferably UK/EU) at buyer’s expense and risk.
Asking €700 and payment via bank transfer or paypal friends/gift.
I have another pair although only one with a working diaper but happy to do a deal with the buyer if they want a spare motor/diaper (as they are now quite hard to find).

PM for further pics/details etc.
