I can say with complete confidence, that I am the second biggest subwoofer nerd in the country. This has been a vital link in mine and many customers systems for over two decades. It’s important to know that almost all subwoofers are awful. Even great speaker manufacturers make subwoofers, little more advanced than what a teenager would put in their hatchback. A few ‘specialised’ manufacturers however, make subwoofers that will transform a system and sometimes yield the largest gain of any of your investments in ‘High Fidelity’. It’s just science and you must work ‘inside the square’.
