Dynamo 1500X offers incredible power and detail with the added benefit
of PBK—a sophisticated room correction system. MartinLogan’s PBK (Perfect

placed throughout the listening room, to tailor the subwoofer’s performance to
the unique acoustic properties of your listening environment. The result is pure,
clean, and powerful bass down to 20Hz.
