215 GMF Midwoofer 40W / 96dB / 8 Ohms

215 GMF Midwoofer 40W / 96dB / 8 Ohms


The goal of the Classic Series is to maintain Supravox's philosophy of developing high-efficiency full-range loudspeakers. We are working to further expand the useful bandwidth for the highest possible performance, while constantly improving the definition, quality and linearity of response. From diameter 135 to 380 mm, the audiophile can satisfy his passion.


This woofer, with very high dynamic qualities, has been developed to harmoniously overlap with any high-efficiency horn system.
This speaker charges in a Bass-Reflex of 40L tuned to 60Hz, i.e. a PVC vent of 125mm by 9cm long, offering a cut-off at 65Hz. Listening to it, it reveals itself as a bass reinforcement of great finesse.

It can be used in pure low-medium in a closed volume of 10 to 12L.

With its 96 dBspl/2.83V at 1m sensitivity, the challenge of high efficiency is achieved and this with a wide linear travel without dynamic compression (+/- 3.7mm). Power handling is the highest of any Supravox 215.
