Pengeras suara PD764i Precision Directivity™ memberikan penguatan suara berdampak tinggi pada jarak jangkau yang melampaui kemampuan desain driver tunggal. Satu modul menghasilkan lebih dari 104 dB SPL (berkelanjutan) pada jarak 50 m (165 ft). PD764i dapat digunakan dalam kluster dengan modul keluarga PD lainnya atau sendirian sebagai bagian dari sistem terdistribusi.
Untuk meningkatkan keandalan dalam kondisi cuaca dan mengurangi infiltrasi air, dimensi kabinet model WRC & WRX mungkin berbeda dari dimensi model standar. Hubungi CustomAudio@harman.com untuk gambar dan/atau informasi dimensi model WRC & WRX.
