Ann: Performance Specifications, page-6

Actually I've made a mistake here 'Also, the 'theoretical' 64 chip speaker, (i'll assume these charts mean max) looks like it can produce 93dB at 100hz. To compare to a home or car speaker, it's about the same, maybe 3dB above average, but look at it tail off after that. '

Most home hifi speakers and car speakers are within this sensitivity range +or-3dB, tested at 1 watt at 1 metre. But the home hifi speakers and car speakers can handle a lot more than 1 watt and achieve much louder levels. What I'm saying is, to achieve the same performance as some cheap car stereo speakers, you woudl probably need 32 times 64chip arrays (2048 chips in your car) PER CHANNEL. This would pretty much take up the whole parcel shelf for just the two rear speakers.
