Performance Features Build Quality Value PRICE $1,100 each; $2,200 as reviewed AT A GLANCE Plus Powerful bass for a compact sub Performs extremely well with music and movies Minus Lacks last half-octave of deep bass you can get from larger subs THE VERDICT If you’re limited on space but have adequate funding, this is the strongest-performing compact sub I’ve auditioned. It’s another American business success story. A couple of kids, Jim Birch and Lucio Proni, begin building home loudspeakers during summer break in 1975. More than 40 years later, Jim and Lucio are still going strong, having seen JL Audio become one of the most respected consumer electronics brands in the world, branching out from the home to mobile and marine applications. I’ve experienced their products at some custom shops and have read glowing reviews of their subwoofers over the years. My favorite review was by my colleague Darryl Wilkinson, who said the company’s Fathom f212 sub could play a 20-hertz test tone loud enough to liquefy his bowels! High praise, indeed.
