JENSEN HYPEX HORN SPEAKER ANNULAR DRIVER
These were removed from a Magnavox tube console years ago, and were made by Jensen. It is impossible jensen hypex horn speaker annular be an expert and we are honestly representing the item to the best of our ability. Lot of 2 crossovers removed from a set of Jensen 23 speakers. The response-frequency characteristic the cone.
Loudspeakers: For music recording and reproduction
These break-up effects lead to a nonuniform response-frequency char- acteristic. The response in the low-fre- quency region is not as accentuated in loudspeaker B as in loudspeaker A. The response at the resonant frequency of loudspeaker B is reduced by a larger mechanical resistance in the suspension system. Listening tests indicated that the sen- sitivity of loudspeaker A was about 3 db higher than B. Most loudspeakers today are evalu- ated by comparing response-frequency characteristics taken on the axis, or by means of listening tests in which the ob- servation points are on or near the axis. In comparison of performance, sensi- tivity appears to be the principal consid- eration. However, careful listening tests will show that the distortion produced by loudspeaker A is very high as com- pared to loudspeaker B.
The distortion tions, the sound output of the jensen hypex horn speaker annular loud- speakers will be the same.
It will be seen that the harmonic distortion of loud- speaker B is very much less than A. This is to be expected, because the rigid- ity of the cone of B is at least eight times that of A. Since all speech and music is of a transient character, the transient re- sponse is another characteristic which depicts the performance of a loud- speaker. Poor transient response leads to fuzzy reproduction with poor defini- tion. As a result, jensen hypex horn speaker annular character of speech or musical instruments is destroyed.
A deviation in the sound output of a loudspeaker from the rapid growth and decay characteristics and the uniform steady state characteristics of an ap- plied electrical tone burst depicts the transient response of the loudspeaker. The responses of loudspeakers A and B to tone bursts at the resonant fre- quency of cps are shown in Jensen hypex horn speaker annular. Fig 5 left. Directional characteristics of a typical commercial in.
Directional character. It will be seen that the general sensitivity is considerably lower than that of Fig. The lower sensitivity comes about by reason of the larger cone mass. The effect of the larger mass of the vibrating system can be deduced from equation 1.

The response-fre- quency characteristic of loudspeaker B shown in Fig. The smooth response is due to the greater stiffness and damping in the heavier cone of loud- speaker B.
The stiffness is increased ap- proximately eight times by doubling the mass, which in turn doubles the thick- ness. An increase in the stiffness of the cone reduces the "break-up" effects in 16 characteristics of these two loudspeak- ers will be examined in the next section. Distortion One of the effects of nonlinearity in the elements of the vibrating system of a loudspeaker is the jensen hypex horn speaker annular of har- monics and subharmonics. Nonlinearity in a cone occurs when the force vs. In a light-weight cone this deviation occurs at a relatively small input.
The total nonlinear distortion fre- quency characteristic of loudspeaker A for an input of 0. The total harmonic distortion- frequency characteristic of loudspeaker B for an input of 0.
Note that the power input of B is doubled to compensate for the de- creased sensitivity. Under these condi- AUDIO It will be seen that the transient response of loudspeaker A is superior to loud- speaker B, because jensen hypex horn speaker annular growth and de- cay are much faster. The responses of loudspeakers A and B to tone bursts at cps are also shown in Fig.
