    These are one of the sweetest speakers you will find at this price. Carl is very good at what he dose. He has done work on my speakers and they now sound like Music not speakers.

    I built a pair of Mltl enclosures for these drivers and the results are spectacular. I used Carl’s final crossover. Stunning performance for very reasonable cost. Thanks Carl.
