CLASSIC DESIGN - The classic DS18 design from the steel basket to the ferrite magnet is sure to create new memories for some of our oldest customers as we enter our 10th year of bringing LOUD products into every vehicle. LOUDEST AND CLEANEST SOUND - The high powered voice coil on the PRO-64XA allows this speaker to retain high levels of efficiency for those never ending jam sessions. HIGH PERFORMANCE - The 96db sensitivity on these speakers allow them to take your sound system to an out of this world volume level. The 4 ohm configuration of these speakers allow them to reach ridiculous sound levels IF they are matched with a compatible amp that runs at the same impedance. POWERFUL CAR SPEAKER - This high-quality 6.5” mid-bass speaker was made for the listeners who like it LOUD just as much as we do. MAX Power Handling 500 Watts. RMS Power Handling 250 Watts. SPECIAL EDITION - In honor of our 10th anniversary DS18 has created the PRO-64XA; a versatile mid-bass loudspeaker designed to do it all.
