Their description on the link makes it appear as though these twiddlers will play lower frequencies than just midrange. As for higher frequencies, typically it is VERY difficult for drivers larger than 3" to accurately reproduce frequencies approaching 15khz to 20 kHz when firing on axis. To compensate, companies often design the car to fire midrange drivers off glass which adds some "sizzle" to the higher frequencies. My favorite audio company, Hybrid Audio Technilogies (HAT) has an audiophile grade 3.7" driver that reproduces these high frequencies so well on or off axis that vehicles running "tweeter-less" 2 way front stages with a 3.7" full range and 8" midbass have won IASCA sound quality competitions. http://store.12velectronics.com/prod...eaker-Set.html That is no small feat, and speaks to the quality of HAT drivers. But those 3.7" drivers run about $530 per pair but the corvette has tweeters also, so I'm not sure of the utility of having "twiddlers" that will also reproduce tweeter frequencies. Hence me thinking that they want these drivers covering more of the midbass duties up front. In any case, it will be interesting to see what the system sounds like. I sat in one today that was on tour in SoCal in Costa Mesa. Not sure if it had the upgraded Bose system and the dealer wouldn't let me turn it up and play with it as all we were able to do was sit down for a few moments in the driver's seat.

Advanced soundstage processing, which is optimized for both seating positions.

How is this different than what is currently on the market, or what is currently in the vehicles. This is what our drivers are currently doing firing off glass.
Also, why have tweeters next to the twiddlers. Seems redundant and unnecessary

I’m not an acoustics or signal processing guy, but I assume that since the car is using a 16 channel amplifier, the tweeter and twid can have their own independent signal path and EQ. That allows for more phase and delay control, thus optimizing the soundstage for both occupants.

That’s the point, they can have different eq’s, phase, and delay.

This noise cancellation technology is evolving pretty rapidly and finding its way into many vehicles now. |
