DSM 25 R - 8 Ohm

25 mm (1") High-End titanium dome driver for the highrange above 2000 Hz. Due to the enormously strong and ultra-light titanium dome and in conjunction with a highly damped sypronyle surround, linear frequency response and no partial oscillations. Due to the enormously high magnetic flux in the ferrofluid-filled air-gap high efficiency and high power handling are possible.

Waveguide WG 220x150

15 x 22 cm Waveguide of high-quality plastic for 25 mm tweeters. The exponential enlargement provides a high sound pressure level gain in the lower high frequency range, which discharges the tweeter. In addition, the focus and the coupling to a woofer are improved, because the sound generation planes move closer together.This Waveguide was adjusted in width and length to 13 cm (e.g., AL 130 8 Ohm) and 20 cm (e.g., AL 200 8 Ohm) loudspeakers.For the connection of the tweeter 4 pieces M4 screws (length approx. 10 mm) are added.This waveguide is suitable for: G 25 FFL 8 Ohm; KE 25 SC 8 Ohm; DSM 25 R 8 OhmPacking unit: 1 pc.
