  • The Acoustic Design of Minimum Diffraction Coaxial Loudspeakers with Integrated Waveguides
    Audio Engineering Society Convention Paper Presented at the 142nd Convention 2017 May 20–23 Berlin, Germany This Convention paper was selected based on a submitted abstract and 750-word precis that have been peer reviewed by at least two qualified anonymous reviewers. The complete manuscript was not peer reviewed. This convention paper has been reproduced from the author's advance manuscript without editing, corrections, or consideration by the Review Board.

Reproduction of this paper, or any portion thereof, is not permitted without direct permission from the Journal of the Audio Engineering Society. The Acoustic Design of Minimum Diffraction Coaxial Loudspeakers with Integrated Waveguides Aki Mäkivirta, Jussi Väisänen, Ilpo Martikainen, Thomas Lund, Siamäk Naghian Genelec Oy, Iisalmi, Finland Correspondence should be addressed to Aki Mäkivirta ([email protected]) ABSTRACT Complementary to precision microphones, creating an ideal point source monitoring speaker has long been considered the holy grail of loudspeaker design. Coaxial transducers unfortunately typically come with several design compromises, such as adding intermodulation distortion, giving rise to various sources of diffraction, and resulting in somewhat restricted maximum output performance or frequency response. In this paper, we review the history of coaxial transducer design, considerations for an ideal point source loudspeaker, discuss the performance of a minimum diffraction coaxial loudspeaker and describe novel designs where the bottlenecks of conventional coaxial transducers have been eliminated. In these, the coaxial element also forms an integral part of a compact, continuous waveguide, thereby further facilitating smooth off-axis dispersion.

  • 11.8 Loudspeaker Enclosures 11-71
    11.8 Loudspeaker enclosures 11-71 11.8 Loudspeaker enclosures 11.8.1 Basics Often, cases guitar-amplifier and -speaker are mounted within the same enclosure (combo); alternatively, there is also the two-part piggy-back or stack design. From the multitude of sizes available on the market, Fig. 11.82 shows a small selection: predominantly, 10”- and 12”-speakers are found, occasionally also 15” (with 1” = 2.54 cm). The small combos almost always have a large opening in the rear while the larger enclosures are either of closed design or realized as ported box (bass-reflex). In the widest sense of the word, the enclosures open to the rear also represent a kind of bass-reflex system – albeit a very special one. Fig. 11.82: Loudspeaker enclosures; Membrane-diameters in inches The enclosure (or cabinet) makes a significant contribution to the sound generation. If it is airtight, it predominantly has the effect of an air-suspension to the membrane that increases the resonance frequency. Since this air-stiffness grows invers to the volume, a small enclosure would strongly increase the resonance frequency – it is presumably for this reason that small 5 2 cabinets mostly have an open back. The stiffness of air is sL = 1.4⋅10 Pa ⋅ S / V for adiabatic changes. In this formula, S is the effective membrane surface, and V is the net volume of the enclosure. For a 12”-speaker and a 50-litre-box, we calculate 9179 N/m – this approximately corresponds to the stiffness of the membrane. As an example: with such a mounting, the resonance frequency for a Celestion Blue would rise by 50%.

  • VHD4.18 Technical Data Sheet
    VHD4.18 Technical Data Sheet Introduction The VHD4.18 is a quad 18" subwoofer system, comprising of four individual loudspeaker cabinets. The objective is to make the system easy to transport and setup. When assembled, the VHD4.18 system becomes a high efficiency neodymium subwoofer system with immense output. The system was designed with very high sensitivity in mind; it provides 110 dB at 1W/1m and a tremendous output of 149dB when running at full power Each cabinet incorporates a large port area that becomes an optimized horn aperture when all four cabinets are stacked together. The quad 18" subwoofer system delivers extreme output and controlled low frequency resolution. Features ● Professional, Baltic birch construction with highly resistant polymer coating Application ● Very High Definition low frequency reproduction Specifically designed to accompany the ● 146dB sustained output / 149dB peak (using 4 units of VHD4.18) VHD2.0 and VHD1.0 as a true full range ● Large chamber horn reflex acoustic design high output system for live performance ● Single 18" low frequency driver with 4" (100 mm) inside/outside, epoxy baked, and music high temperature voice coil assembly and neodymium magnetic structure ● Proprietary side handles (6) for simplified handling and carrying ● Hire and Production ● High impact low friction feet, allowing lock-in to other VHD cabinets and easy ● Concert venues cabinet movement ● Large Theatres ● Front locking aluminium VHD wheel boards with wraparound hardwood bumpers ● Scalable into multiple large systems ●
