So I've been on a bit of a deep dive into what I can do with this base system. And I've found an ebay seller selling total kits for different models for about 1/2 what bavsound does.
What's interesting though, is that his systems appear to be based around this:

It's actually a driver I have experience with in home audio settings and IS very good.
Anyone have thoughts on just using these as full range speakers in the HiFi setup? I've used them as pure full ranges in bookshelf/desktop speaker projects and they're actually quite good, on axis. My concern is in the car the off axis response and the highs. But, with the center and rears reflecting off glass I don't think it'll be that much of an issue, and with how the base speakers are, it can't be worse, and I've noted most people who drop in coax speakers say they end up dropping the treble -5 anyway.
Granted, they'd need brackets and ideally wiring harnesses, but for ~$150 total for all five speakers that's one hell of a deal imo.
Anyone have any thoughts on this?
