Raal "Dipole 140-15D" Ribbon Driver

Special Order Only - 3 to 5 weeks delivery

The 140-15D includes no deep slots or short horns--created by bulky magnets in the vicinity of the ribbon element--which increase air loading mass and compromise linearity. 
The result is that acceleration and linearity are preserved. Totally symmetrical front and back openings provide identical response and dispersion patterns. To adjust for different and independent dispersion patterns in the front and back of the driver, a speaker builder can use Raal's proprietary foam deflector pads. In this fashion a speaker builder can add amazing depth in the stereo image, and allow for listening room adjustments. For the first time, you don't need electronics to adjust front and back levels!
The RAAL Dipole is the thinnest dipole true ribbon on the market.
