A brand that wins countless SPL competitions over the years, can’t build a premier sound quality sub. Or can they? The Incriminator Audio Flatlyne is proving people wrong while making a serious name for Incriminator Audio in the Sound Quality world of car audio. A great way to do that is to pick up Sound Quality champions using the IA Flatlyne in MECA and IASCA. The first generation of the IA Flatlyne established itself in the hard-core sound quality crowd. Now, with the second generation Flatlyne, Incriminator improves on the already very successful under-hung motor design by upgrading to a light weight, Neo magnet motor for improved motor force, that now employees a full sleeve copper shorting ring. What this means is reduced driver displacement for smaller enclosure requirements as well as better cooling and lower inductance for serious precision.

The Flatlyne uses an 8-layer 3” copper coil with dual black progressive spiders and woven leads. As well as a dual layer foam surround, an outstanding injected pulp matrix fiber reinforced cone and an interlocking spider spacer assembly in addition to the Air Driven Cooling (ADC), the Flatlyne shows it can take some power and stand up to daily abuse while still sounding amazing. The Flatlyne has Incriminators new 8 spoke basket, and is available in Dual 2 ohm coils and Dual 4 ohm coils, in 12”, 15” and 18” sizes. Conservatively rated at 600 RMS, you don’t need massive power to get awesome results. This model is called the Flatlyne because of such incredibly smooth response across the range and that it is deadly accurate no matter what music you throw at it. For bass so clean it will make your heart stop, the new for 2017 Incriminator Audio Flatlyne is the choice of champions.
