Recommended unconventional (planar, bending wave, etc.) drivers summary:

The following tables summarize the significant specifications of all recommended unconventional drivers. These may include planar magnetic, ESL, and/or bending wave transducer (BWT) drivers.

Notes:

Most frequency range (FR) data is supplied by the vendors, occasionally without any tolerance specified. Where backup data (e.g. curves or independent tests) are available, the manufacturers' specs may be modified to more closely match the measured data.

All other notes for Sections 8 and 9 apply.
