TWO heavy duty American Made Eminence 10-inch Delta Bass Speakers. 8 ohms each, 4 ohms when paired. Delta 10's have 56 oz magnets and 2.5 inch voice coils rated at 350 watts RMS per speaker. These two speakers combined are rated at 700 watts rms--that's a lot of punch! Purchased for a custom bass cabinet, but turns out I should have ordered two 16 ohm speakers. So, these were installed in a cab, confirmed functional, then removed and returned to the factory original packaging. No issues, guaranteed.
