LE-S is more! DD Audio LE-S06d is a very compact loaded enclosure. Next generation of famous LE-S06 is now even better. Driver has all new desing that gives more lower bass thanks to lower fs-value. Spider, surround, cone and all parts of this little beast are re-thinked and re-designed to outperform the previous model. Excellent choice to a truck cabin, small car, van cabin etc. Outer dimensions of the box are same than before.
