See the speakers Bose uses in their Critical Listening Room

@millercarbon, thanks I must be blind.  Would be interesting to know what drivers they chose.

From what I have heard from associates in Boston, there are a lot of audiophiles who are engineers working at Bose. There job is not to make audiophile products, but products that sound "good" and easy to use. Just like they are engineers who love racing working on the next plain Jane Honda Civic. You do your job.

A number of us audiophiles are using their QC35s for traveling,  better than PSB, or Sennheiser in noise cancelling and they sound descent.

By the way, what Bose, and Harmon are able to do with OEM systems are incredible, especially if you knew how little they are paid per car vs what you would pay aftermarket.

The 901 is no longer being sold.............(thank goodness).
