The story of our Twin 8 series subwoofer upgrade is below.
The R35 GTR is an iconic Japanese supercar with a long-standing history of being an incredibly fast production vehicle. One shortcoming however, is that the factory stereo system does not measure up to the GTR standard of high performance. In fact, in many cases the bass provided by the factory GTR audio system is difficult to hear over any aftermarket exhaust. You may wonder why the bass is underwhelming because the factory subwoofer box looks like a large and somewhat impressive housing with Bose subwoofers. In reality, the factory subwoofers are free-air bass drivers that are 2″ in depth that vent into the trunk. The small size and minimal excursion of the factory subwoofers prevent them from being able to produce the amount of bass that you would typically hope for. To leverage the existing actively processed three-way front component speakers and enhance the overall sound without significant modifications, we chose to only focus on a drastically improved bass solution. So let’s get into the specifics of why this system is so special and sounds so great:
The new R35 Twin 8 series subwoofer enclosure is acoustically engineered. Every curve, angle, and measurement is by design with the goal to sound as good as possible in the GTR cabin. EQ parametric micing has been taken into consideration to overcome the unique interior pressure and shape of the GTR. The mounting angles of the subwoofers are also designed to produce optimal wave propagation and have the sound stage converge exactly at the driver and passenger seating positions. The inside of the box is the exact spec volume for the subwoofers and there are no sharp angles inside the box to eliminate any airflow turbulence. Sound testing included a six-month trial period in controlled and real-world driving conditions. In total, this system has over 1 year of research and testing invested and the original version of the twin 8 has been producing deep and accurate bass over the last 5 years. There is no compromise anywhere in this subwoofer upgrade.
