Sonic Bliss - E90/92/93 Enhanced Audio Stage 1
After nearly two years of development, we’re proud to release our Stage 1 for the Enhanced Audio equipped M3 coupes, sedans, and cabrio (front soundstage only).
In removing the tweeter from the front center channel, we’re much better able to control the imaging of the front soundstage. The addition of custom-tooled crossover networks give precise control of the image as it dances across the windshield. Paired with our 25mm silk-composite domed tweeters in the side mirror sails and custom 100mm midrange drivers in each front door, we’ve struck the perfect balance in your M3.
In layman’s terms, what does all of this mean? You guessed it; an incredible sounding, easy to install upgrade for your M3.
Here are some thoughts on our new crossovers included in our Stage 1:
- The crossover network was empirically optimized to have a warm, balanced sound. In addition to CAD, the circuit itself has evolved through extensive listening to provide effortless sound quality.
- Crossover slopes have been engineered to complement the natural responses of the tweeter and midbass drivers. This results in a more dynamic sound while avoiding added circuit complexity and its inherent phase shifts.
- High quality component parts such as film capacitors are used in the signal path, along with over-rated resistors and high linearity inductors. In particular, a ferrite shielded inductor is employed to minimize interaction with metallic door panels as well as other circuitry inside the door.
- The circuit board itself is designed with massive high current paths, as well as parallel topology.
- The tweeter circuit includes -3, 0, and +3db attenuation options. A heavy, gold plated buss bar is used to select attenuation, thus eliminating unreliable switches or high contact resistance.
- The tweeter is protected via a self-resetting solid state circuit breaker with bypass. Unlike most designs, overload will not completely turn off the tweeter. Instead, the tweeter continues to operate but at a reduced volume.
- As in high-end home audio applications, a Zobel impedance compensation circuit is used to maximize the crossover’s overall performance.
