When Mach 5 released the MJ-18 over four years ago, we hadn't a clue just how popular they would become. Not only was the MJ a smash hit for home theater DIYer's but tons of folks used them in car audio applications as well. The price-per-pound 
break point of the MJ, and later, the entire MAW series of subwoofers, made Mach 5 Audio stand out over other "companies" trying to peddle similar product costing heaps more.
Through the SPL series, to the IXL line, and now the new FTW-21, Mach 5 Audio continues to deliver high quality products at pricing audio enthusiasts can afford, and of course, continue to expect. The accolades we receive from end users tell us we are doing the right thing, and that's all that really matters.
