W4-1720 by Tang Band
With the W4-1720, Tang Band presents a 4 "(10cm) deep-midrange man, which convinces with innovative technical features. Our focus here is on a bass speaker with an excellent feature specification. With its subjugated 1-1/4-inch vibration coil, driven by A massive ferrite magnet structure and paired with an optimized paper membrane, the W4-1720 is really an audio-technical highlight. Its rubber is guaranteed, which are of high quality and durable.
The 4-inch middleman W4-1720 has a wide-ranging, hooked 1-1/4-inch vibrating coil, which is driven by a massive ferrite magnetic structure. A short circuit ring on the polkern is responsible for the extremely low level of the harmonious distortions of the second and third order of the speaker. This impressive engine is coupled with an optimized paper cone with rubber decay, which is worn by an aluminum cast frame.Highlights:
