7-372/32 Hex

7-372/32 Hex


A long throw woofer / midrange speaker with heat pipe technology. Its open front construction method is the prerequisite for a correspondingly open sound reproduction. This characteristic increases in the high frequency range, and for this reason perfectly allows the combination with “airy” and “light” sounding tweeters.
