Wondering if Rennspec could put together a recommended package - Better, Even Better, Best with cost in mind and Basic, Improved, Ultimate with sound in mind. Of course the idea is to provide the "newbie" with your expertise in speaker selection and getting better sound with your offerings based on price point. Don't know, but maybe some different speaker combinations would match up nicely. For example:
Basic Better - might be just replace the tweeters with lowest cost of what they offer.
Basic Improved - just replace tweeters but with a mid range cost.
Improved Better - maybe replace the tweeter and midrange with lower cost
Improved Even Better - replace tweeter, center and midrange with moderate cost

Cool stuff! Currently have the musicar tweeters on a Bose system with the center dash speaker disconnected. What would be a logical next step up from here? Upgrade just the mids and see how that sounds? Seems like the Bose woofer is decent and less bang for the buck there.

As Carl mentioned, adding some sound deadening to the doors can help tidy things up as well.

cool great idea. Have material and so will do that. If I wanted to do mids which would be recommended of the rennspec options to go with the musicar tweeters and Bose woofers? If I’m reading the spreadsheet right I’d need 4 mids total?

Dynaudio Esotan MF 171 MKII Midrange Kit
- Features: Diaphragm design: 3in diameter MSP, Impedance: (4±15%)Ω at 3550Hz, DC resistance: (3.6±15%)Ω, Measured characteristic sensitivity/1m: (86±3) dBSPL, Recommended frequency range: 160~14kHz, Nominal long-term IEC: 120W, Transient: 1000W, Net weight: 0.5kg, and Overall dimensions: 100 x 56.8mm.
Not much price difference between the price 3 Rennspec offerings. Maybe the more affordable Dynaudio option would be a good since your tweeters are Dynaudio?

This is a great idea and about time someone came up with a solution for plug and play.
The biggest problem with these 991 systems is the amp and this is the one area that isnt being addressed. Probably because it isnt so easy and not just a plug and play for the DIY'er.
You can improve the stock system significantly with better speakers, but if you don't change the amp you will never have the power, lack of distortion or clarity you need for great sound.
Make a system that incorporates an amp for those looking to transform the sound into top quality and keep the plug and play speaker kits for those that just want moderate to good improvement.
For most people, changing the speakers (and sound deadening) will be more than enough and far better than the Burmester at a fraction of the cost. But, even the Burmester is lacking to audiophiles.

You can replace all 4 with the same speaker, or considering going with a nicer pair like the Esotar 430 in the front and then maybe the Esotan or Audison in the rear.
Great question!
Porsche uses the same speakers in most of their current cars, so there is quite a bit of overlap in the what sizes fit in which vehicles. There is some variation, so for example the while the 991 will support the 8" and 10" Dynaudio woofers, the Cayenne has less available depth so the only options would be the 8" Audison or 6.5" Dynaudio.
Then there are some applications like the Cayman (and Panamera/Taycan) where we just don't have enough experience to say which speakers will fit in all locations. The mounting holes and wiring are consistent, so there is a good chance the tweeters will work - but there could be other factors which may have an impact.
Happy to chat further about options here, so feel free to drop me a PM.

We may look at doing something with amplification down the road. Lots of options to explore.

Christian, I agree with you. There is only so high quality a speaker you can realistically install without changing the Amps. At some point the premium speakers are overkill and unnecessary if you cant drive them cleanly.
However, there is a lot of room for improvement over the stock speakers (absolute junk) where you can retain the factory amp and get significant improvements.

We have tried to lay out various options at different price points on our site to accommodate the varying goals and enthusiasm levels people have for upgrades.
Thanks for the feedback though.

I'm not a pro but I have had good results using the Infinity Kappa tweeters in different Bose systems, never had a problem and they don't break the bank. They are 2 ohms with 93 db which do very well with the Bose amp
Waiting for the new ones to come out, just need to figure out how to install them
Some Info:
Infinity Kappa 10.11t
