DS18 PRO-84XA 8” 10th Anniversary Mid-Bass Loudspeaker 550 Watts Max 4-Ohm For 10 years now, DS18 has supplied all vehicles with the loudest and cleanest sound the streets have ever heard. In honor of our 10 th anniversary DS18 has created the PRO-84XA ; a versatile mid-bass loudspeaker designed to do it all! This high-quality 8” mid-bass speaker was made for the listeners who like it LOUD just as much as we do! The 97.8db 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! 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 10 th year of bringing LOUD products into every vehicle. Highlights Steel basket for elevated style and durability The high powered voice coil on the PRO-84XA allows this speaker to retain high levels of efficiency for those never ending jam sessions
