Checking the B&C website reveals no patent claims on the DE-250 data sheet or in the company information. The driver materials, diaphragm shape and other features don't appear significantly different than comparable 1" compression drivers and it seems doubtful that there would be intellectual property issues. The main concern for the consumer would be availability of the product and support. Replacement parts - in this case the driver diaphragm - should be easily obtained. Parts Express is probably as stable a supplier as can be found in the audio and electronics industry at this point.
Parts Express has a history of providing the DIY audio community with a source of quality products no longer available from other vendors. Subwoofers comparable to the long discontinued Adire Audio Shiva and Tempest live on as the Dayton DVC series. They are American made. The QSC horn in the Econowave is only available due to the investment by Parts Express. The company has been aggressive in copying some of the better audio products available and manufacturing some of them overseas. They have also produced many original or uniquely modified products. Many loudspeakers and other audio products fabricated here or in Europe depend extensively on parts sourced from Asia. These are commonly accepted business practices and usually lead to greater product variety and value for the consumer.
The loss of US manufacturing is a very complex issue that carries with it a deep emotional response from many Americans. I have no affiliations with Parts Express and brought attention to this product only to enlighten others. Pi Speakers provides a valuable service to the DIY audio community through this forum and if any distress has resulted from these postings, please accept my sincerest apology.
