  • Regular price $ 1,099.99

A single lightweight 15″ cabinet with warm tones, and a punchy mid range.



In the neo/light version, the bass cabinet built with a state-of-the-art neodymium transducer in an 8Ohm configuration (A 4Ohm model is available by special order and takes 1-2 weeks to manufacture). Ideal on its own or stacked with a 2B10L (an extremely popular combo) the 1B15L delivers Form Factor’s signature tone and reproduces the entire musical spectrum phenomenally well. With a 1.4″ Compression driver and 90×60 horn and a unique crossover, this single 15″ delivers a rich and distinct sound. The cabinet is machine made on a state of the art CNC router, then hand assembled for an unparalleled level of craftsmanship and quality, delivering an unsurpassed amount of rigidity. Cross braced and made from Italian Lite Ply plywood, the cabinet’s strength adds immensely to the tone. The design and construction of this cabinet allows the woofers to work at their optimal range, delivering a bigger, fuller sound with the added convenience of lighter weight. Like all Form Factor products, the 1B15 is Made in the US.
