Audio is my career for 32 years, cars I love, and I love my Genesis.
Harmon make some great audio equipment, though the company has not been bringing in the revenue the past few years and is struggling some. They pretty much own a lot of the car market with all their different brands.
I would not get too excited about the name
badges, a great JBL system in another car, or Becker will sound as nice as the Genesis 14-17 speaker system. You don't get a lot of sound out of some of these 1-2 inch tweeters.
I have the 17 speaker car stereo, it's great, maybe one of the best I have had in a "factory" stereo, but remember, this is not home audio, and road and inside car noise, and of course, ability to listen with much attention, and even passengers bodies blocking the sounds, makes a big difference.
Some Harmon names acquired over the years include AKG Acoustics, Audio Access, Becker, BSS Audio, Crown International, Harman/Kardon, Infinity, JBL, Lexicon, Mark Levinson. Before Harmon bought JBL (James B. Lansing), Infinity, Lexicon and Mark Levinson, you would never see some of these high end home audio brands placed in a car before Harmon bought them.
They used to keep their auto limited to Clarion, but I believe the dropped the name over the past few years with all the high end companies going under and them buying them up. It is a license fee they pay the automaker, yes, Lexicon, and Levinson is higher end sound, but if the auto company bucks up, you get the name, probably many of the same exact speakers. Lexicon got in some big trouble and lawsuits before they went under and Harmon grabbed the
badge. Lexicon had their high-end home $3000 DVD players which were being made by OPPO (which sold for about $600-$900 bucks). OPPO is the best DVD player you can get for the bucks now, the Genesis of DVD players.
The car interior which the Genesis had one great one, makes such a big difference, just like a dedicated home stereo room. Harmon will get involved with speaker placement with the auto engineers to get the best sound in the cabin. Good placement of mid range, tweeters, to off set all the carpet, leather and glass (which is a very tough material for sound). All is Harmon, and you will find many of the same internal parts in all systems. High end JBL, HK, Becker, and even after market Clarion systems are very similar and hard to tell a difference. Hey, at least it is not Kraco from K-Mart!
Watts are not regulated by any agency, so one can never compare apples to apples. and putting a 500 watt McIntosh home amp, will give your ears a whole new understanding of what a high end amp really sounds like. McIntosh even went in some auto's, I think the Ford GT @ $250K got one, I am not talking about Mustangs.
So whether 4-6-10-14-17 speakers which are hard to put into cars with the limited space, enjoy the sound and make sure you stay under 90 db, your ears will last you a lot longer. Download an AP on your phone for a buck to measure the db's in your car.
Also, if you use an iTunes, don't buy shaved music, get Apple's higher end music download, still shaved, but at 320, good enough for the average human ear versus the 128 all mid range, otherwise your feeding a nice system a lot of lost treble and bass notes so you use less hard drive space and buy more music. It's .29 cents more a song. Some artist are recording CD's on MacBooks in a barn that on a good home system, sound like crap, but high end home audio is pretty much dead these days.
It is a very nice car audio system, but Harmon puts "high end" in a lot of their brands.
