The Laboratory Speaker is a quality, high-power (30W RMS) 4” loudspeaker on a robust metal base suitable for all laboratory applications.
Description
A Physics Lab essential, the Lascells Laboratory Speaker features a high quality, full range 4″ speaker, mounted to a metal base with standard banana jack plugs. Suggested demonstrations include: finding the range of human hearing; showing that volume is a function of diaphragm displacement; dancing oobleck/cornflour (ensuring that the speaker is protected with cling film); interference, for which two speakers would be required, and coherence provided by the dual output on the LA50-555 Lascells Wireless Amplifier (not included). The optimum audio frequency range is 80 Hz to 22 kHz, but the speaker will respond to signals well beyond this range when required.
