Maintained! JBL's large speaker system equipped with a 46cm woofer. Compared to 4343 and 4344, the overwhelming sense of volume of bass played by a super heavyweight woofer is a masterpiece. Sufficient leeway is secured for low frequency reproduction, and sounds that are driven loudly do not lose their outline and are expressed with plenty of punch (Oikawa Tetsuji)
