They list this as a 2 inch driver. It's outside dimension is 2.56" so we are listing as 2.5" diameter driver - May not be that important to most but if you are limited on where it is going to be installed you need to see all the details concerning the OD, mounting hole size, depth & more below.
Great little driver for unique compact speaker projects. Contact me with questions. We have a few still available and also some with minor marks on the front of the flat speaker cone from handling at a nice discount. All are brand new and unused, never mounted, etc.

BMR Series are the first full-range, off-the-shelf drive units using patented BMR technology. Square BMR12 2" drivers combine the qualities of  flat panel speakers and the pistonic movement of conventional speakers. The technology's wide directivity enables flexible placement options, while the wide frequency response means BMR drivers can also deliver cost savings to engineers, since no crossover components or frequency-specific drivers are required. Excellent for line arrays or most any other type of sound project where space is limited and sound performance can't be sacrificed!
The BMR12 2" drive unit has an excellent and extended frequency response with wide directivity and is ideally suited to compact full-range applications that require a high performance acoustic solution. Typical examples include MP3 player docking stations, Internet/DAB (Digital Audio Broadcasting) tabletop radios, and home theater speaker bars. Just use your imagination for projects that you can apply such a small and shallow depth speaker. Requires less than 1 inch of mounting depth.
