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.

  • Great SQ sub with plenty of output

    Posted by Ross McElroy on 21st Dec 2017

    I've owned my own shop and been through many subs. I got the 15 inch Flatlyne and put it into a 3 cubed box tuned to 35hz with plenty of port area. I have always made my own boxes but table saw and router and nail gun are in storage and did not want to mess with it. Got the box from mobilesoundworks and it is well made, 3/4 MDF etc no internal bracing and they did not router the port opening on either end which is no big deal with the power 400 watts I am giving the sub. It is being powered by an AudioControl D-4.800 giving the sub 400 watts at 4 ohms dual 2 ohm sub wired up to 4. I have mid level Morels up front getting 125 rms per side. from channels 1/2 of the Audiocontrol 4 channel which has an internal DSP which is very cool. Sub blends perfectly with the front stage in my Toyota Sequoia. Sub is crossed around 75hz @24db's and fronts are around the same on the high side. I did some minor time alignment for the sub and with the remote level knob from the Audiocontrol amp it's easy to dial in just right. The sub blends so well it sounds like the bass and midbass is all coming from the front doors. It hits clean and clear and has more of the upper bass than I would have thought which helps it blend. I love the sub it is so clear and accurate and at at a great price. I'm sure I could put more watts to it with one of my Ground Zero Amps or Mmats but at 400 watts it has great output since it is very efficient and light weight.

  • Great Sub!
