Bass cabinet from Hartke. In 1984, Hartke revolutionized bass amplification with the first all-aluminum cone driver which produced bass tone with broader dynamics than ever before. This led to the original Hartke XL Series Bass Cabinets. Now, to commemorate 35 years of the "Hartke Sound", the new 210XL V2 Bass Cabinet will house Hartke's classic 2 x 10 all-aluminum speaker design inside a more durable, modern-looking cabinet enclosure that packs 200 watts of power handling.
