PURPOSE:To make the frequency near the crossover stable in a sound pressure characteristic, by arranging and positioning a woofer and a horn tweeter closely. CONSTITUTION:A front load horn 9 is provided at an upper part of a cabinet 8, a ceiling of the cabinet 8 constitutes a part of the front load horn 9, and a step 11 projected upward is formed at the ceiling corresponding to the inner edge of the horn 9. The step 11 is fitted with a woofer 12. At the upper part of the ceiling of the cabinet 8, a horn tweeter 14 is fitted horizontally through the use of the said step 11. Since the woofer and the horn tweeter are closely arranged and fitted at the step of the cabinet, the position of sound source is made constant and the frequency near the crossover can remarkably be stabilized, allowing to obtain a flat characteristic. |
