The new REDLINE Series coaxials and component speakers were designed to take your daily listening to the next level without taking your hard earned cash. Available in sizes ranging from 4” to 6×9”, the new Redline series speakers cover most factory replacement needs while their compact motors and baskets make for an easy drop-in installation process. A balance between power efficiency and power handling design elements allow these speakers to perform well at factory power levels, while they really come to life when paired with an aftermarket DD Audio amplifier. Solid Performance. Sizable Savings!
