Just curious if anyone would be interested in a group buy from these folks. They design upgrades to factory systems for Mercedes, BMW, Ferrari, and now Tesla. There are a number of threads about them on the Tesla Motors website. Anyway, they have designed 3 different upgrade packages for the S. Rick who works with them described the first two packages in detail. He said the Tesla Studio System is hampered by not enough power and some of the speakers are pretty poor. Level 1 - upgrades a number of the speakers and adds an amplifier. Biggest difference is the A pillar speakers which produce 70% of the sound. Big upgrade for general listening. ~$3,000 Level 2 - level one plus adds subwoofer in the footwell (a detachable one should you need the space) that takes up ~ 1 cubic foot of space. ~$3,700. Most people are interested in this. Level 3 - was vague on this, I wasn't really interested anyway, says they haven't sold many. 4k+ Says the first 2 levels are aesthetically unobtrusive to the car. Level 1 completely so. The only thing that changes is the way it sounds. You can still use all the sound controls on the touchpad. Level 2 adds the subwoofer but says it looks like it belongs in the car. People rave about their systems. Here's the man thread: http://www.teslamotorsclub.com/showthread.php/16001-My-audio-upgrade-for-quot-Watt-ME-quot-Reus-Audio You can also check out their website here: http://www.reusaudio.com/ Their site is pretty vague. Rick said this is intentionally so as other companies will try to clone what they do and produce cheap knock-offs of their packages. Makes sense... Folks in Boston and Southern California are organizing group buys. Apparently they come through Dallas quite a bit anyway so it's likely they will swing by as a matter of their normal business. However, if we can organize a group buy, the price per person drops (because they amortize the travel costs over more people). If anyone is interested, post here or message me. Apparently there are over 100 Model S cars in DFW so if we can get 8-10 we'll be in good shape.
