2. Band-pass filter - Wikipedia

   en.wikipedia.org/wiki/Band-pass_filter

   Compound or 4th order band-pass enclosure. A 4th order electrical bandpass filter can be simulated by a vented box in which the contribution from the rear face of the driver cone is trapped in a sealed box, and the radiation from the front surface of the cone is into a ported chamber. This modifies the resonance of the driver.

   Microstrip circuits can be manufactured by cheap printed circuit technology, ... "A comparison of four overmoded canonical narrow bandpass filters at 12 GHz", ...

4. Loudspeaker enclosure - Wikipedia

   en.wikipedia.org/wiki/Loudspeaker_enclosure

   Compound or 4th-order band-pass enclosure. A 4th-order electrical bandpass filter can be simulated by a vented box in which the contribution from the rear face of the driver cone is trapped in a sealed box, and the radiation from the front surface of the cone is directed into a ported chamber. This modifies the resonance of the driver.

5. Thiele/Small parameters - Wikipedia

   The 1925 paper [1] of Chester W. Rice and Edward W. Kellogg, fueled by advances in radio and electronics, increased interest in direct radiator loudspeakers. In 1930, A. J. Thuras of Bell Labs patented (US Patent No. 1869178) his "Sound Translating Device" (essentially a vented box) which was evidence of the interest in many types of enclosure design at the time.

6. Audio crossover - Wikipedia

   en.wikipedia.org/wiki/Audio_crossover

   An extra HPF section may be present in an "N-way" loudspeaker crossover to protect the lowest-frequency driver from frequencies lower than it can safely handle. Such a crossover would then have a bandpass filter for the lowest-frequency driver. Similarly, the highest-frequency driver may have a protective LPF section to prevent high-frequency ...

7. Distributed-element filter - Wikipedia

   en.wikipedia.org/wiki/Distributed-element_filter

   The purpose of the block converter is to convert the satellite signal to a much lower frequency band that can be handled by the downlead and the user's set-top box. Frequencies depend on satellite system and geographical region, but this particular device converts a block of frequencies in the band 10.7 GHz to 11.8 GHz.
