A lot of material will be recycled from this lot because it is not useful, but some components such as transformers, valves, coils and passive components will be selected and tested by an electronic expert for resale. Posso unire gli articoli acquistati ed effettuare un unica spedizione facendovi pagare un solo costo di spedizione. Grazie e buon proseguimento I can combine the items purchased and make a single shipment making you pay only one shipping cost. Thank you and good continuation Before bidding, if you are not sure, do not buy.

The horn provides uniform on and off axis frequency response from Hz to beyond 16 kHz in the horizontal plane and 2 kHz to 16 kHz in the vertical plane with constant directivity above 2 kHz. The exceptionally consistent horizontal dispersion eliminates the midrange narrowing and high frequency beaming problems typically associated with conventional horn designs.
Additionally, the highly predictable performance of the A greatly simplifies cluster design. The need for horn overlapping is minimized and lobing and comb filter effects are virtually eliminated. Computer-aided design techniques were used to derive the horn contours in the horizontal and vertical planes.
Utilizing sidewall contours based on a polynomial power series formula, the horn design yields smooth response, low distortion, and even coverage.
This design avoids the performance disadvantages of horns that feature sharp flare transitions and flat sidewalls. The Bi-RadialT M compound flare configuration provides constant coverage over defined, solid angles. To ensure light weight, superior strength, and freedom from esonances, the horn bell is constructed of molded structural foam. The A will accept the 49 mm 2 in diameter throat , , or compression driver With the addition of the adapter, the horn will also accept the 25 mm I in throat driver.
Features Uniform horizontal on and off axis frequency response Precise horizontal and vertical pattern control Full horn loading to Hz Flat front and compact size Lightweight construction 49 mm 2 in throat entry.
