The M-909¡¯s are fairly efficient at 92 dB so a good 100w (that doubles down at 4 ohms) power amp should drive them pretty well with plenty of headroom.
How big is your listening room? ?Are you buying new or used?
Wow that was easy. I¡¯ve been googling these speakers for a while and couldn¡¯t find any specs on them. Thanks! Do you happen to know the maximum power they can handle?
