Double Audio Kit with filter , specific for small migrating birds

Kit for small migratory birds, used to call specially song thrush, redwing, fieldfare, skylark and pipit.

This kit has two speakers, the first specific to reproduce  high frequency sounds and ultrasounds (micro-speaker), the second is a micro trumpet specific to reproduce the medium frequency sounds and able to develop a very high acoustic power, thank to its neodymium magnet able to reduce its dimension. 

The micro speaker for high frequencies is connected to a filter that separate the frequencies coming from the device, optimizing the acoustics for a more effective call and also avoiding breakage of the speakers due to the too much power emitted by the professional MP300 and F60 digital reproducers.

The Double Audio kit is at disposal with a high quality RCA jack with chemical gilding.
