paper cones and plastic baskets.

They put in 1 ohm drivers for ****s and giggles.

 

Thanks for saving me some time!

 

Thanks evhudsons

 

Per gasongasoff, it sounds like the bose system uses 1 ohm drivers. Per others, it sounds like 997.1 and 997.2 bose are same part. Based on this, I definitely would not replace existing speakers with 997.2 unless existing are blown.

In terms of replacement with aftermarket, just about anything would sound better than the stock paper cone bose speakers. The problem is...good luck finding a 1 ohm replacement (hence the logic of using a non-standard impedence...if your speaker blows, you must use bose). A really good website is parts express. They just might have something that would do it.

If you can find a better quality (look for something with a butyl rubber surround) at the right size and right impedence, it is likely you will get a good bang for the buck improvement in sound. Otherwise...again, slippery slope to full system changeout.

 

This tread is confusing me. Are we saying that we can simply replace the tweeters in the bose system with focal units and it would already increase quality of sound? Are we saying the focal impedance matches the bose tweeter units being replaced?

 

According to the experience of evhudson, yes.

No. The impedances would be different. But as long as the voltage sensitivity of the Bose vs. Focal tweeters are similar (i.e. XX db/ YY volts), then the system "brightness" would probably be close. Impedance is only a problem if a) the driver impedance is lower than the amp is rated for (i.e. 1ohm driver for an amp designed to drive 4ohm loads) or b) you're using passive crossovers that rely on the driver impedance to determine the crossover point. Neither is the case here.

 

Gasongass off mentioned two things that I had not considered which may damage the tweeters, the crossover and the capacitors. The crossover to eliminate the midrange signal as it is shared with the tweeters per the wiring from the bose amp, and the capacitor to help with any sudden surge on the tweeter. Even without the crossover the sound is immediately better, but Tito had pointed out in my thread that he found a bunch of tweeters with built in crossovers. I have a feeling that even a partsexpress tweeter with built in crossovers would be far superior to what was in my dash previously. I would think the money they put into the sound system was in priority: Double din nav and cd player, then the fiber optic bose amp, the subwoofer and enclosure, and lastly the crappy and I really mean crappy speakers. In every system I've ever had the end of everything comes through the speakers, so your money is best spent there which is not what I'm finding in the Porsche.
