Datasheet
15 PT 400 MB [3.0]
The Sweton 15 PT 400 MB [3.0] is a 15- inch professional mid-bass transducer engineered for high-output live-sound and installed systems. It pairs a powerful, highly symmetric motor (Bl = 20.4 N/A) with a moderately stiff, well-damped suspension to deliver high sensitivity (≈100 dB, 2.83 V/1 m) together with low largesignal distortion. The driver is intended to cover the low-mid to mid band – nominally 100 Hz to 2 kHz – where its flat, controlled response and high efficiency let it produce high sound-pressure levels from modest amplifier power.
