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 Ohm Packing unit: 1 pc. Technical Data: Cutout diameter 125 x 185 mm Net weight 190 g Cutout diameter D = 38 mm https://elecena.pl/product/18519276/5175-waveguide-150-x-220-mm 2021-05-20 https://elecena.pl/product/18519276/5175-waveguide-150-x-220-mm 2022-12-02
