Original speakers designed for guitar, but you could use for practice bass (i.e. low volume). To gig with, change over to Ampeg/Eminence 10" SVT replacement speakers. Rated for 32 Ohms each but wired in parallel would yield 5.3 Ohms, safe for solid state (Kustom, sunn) or tube amps (ampeg, fender) that are rated for 4 Ohms or higher.
