Theater owners also had the option of purchasing only the Cerwin-Vega drivers and horn cabinet blueprints, buying the wood and making the horn cabinets themselves. MCA made these changes due to the success of the system and because the shipping costs of the heavy Sensurround horns were becoming very expensive.
Cerwin-Vega was founded as Vega Associates [4] (with later name changes to Vega Laboratories and then Cerwin-Vega) by aerospace engineer Eugene J. "Gene" Czerwinski (1927–2010) in 1954, [4] and became noted for producing an 18" speaker capable of producing 130 dB in SPL at 30 Hz, an astonishing level during its time.
Paul Wilbur Klipsch (March 9, 1904 – May 5, 2002) was an American engineer and high fidelity audio pioneer, known for developing a high-efficiency folded horn loudspeaker. Unsatisfied with the sound quality of phonographs and early speaker systems, Klipsch used scientific principles to develop a corner horn speaker that sounded more lifelike ...
The Voigt pipe is a type of loudspeaker enclosure that embodies a combination of transmission line, ported enclosure and horn characteristics. It is highly regarded by some speaker designers, as evidenced by established manufacturers such as Castle. Due to its relatively high efficiency the design is frequently employed in full-range ...

There are many ways in which the duct can be folded and the line is often tapered in cross section to avoid parallel internal surfaces that encourage standing waves. Depending upon the drive unit and quantity – and various physical properties – of absorbent material, the amount of taper will be adjusted during the design process to tune the ...
