The low-frequency performance of a vented-box loudspeaker system is directly related to a small number of easily measured system parameters. This system is a fourthorder (24-dB per octave cutoff) high-pass filter which can be adjusted to have a wide variety of response characteristics. Enclosure losses have a significant effect on system performance and should be taken into account when assessing or adjusting vented-box systems. The efficiency of a vented-box loudspeaker system is shown to be… 

Enclosure Design for Direct-Radiator Loudspeakers

The design of direct-radiator loudspeaker enclosures must be closely related to not only the resonant frequency of the speaker but also its loaded Q and compliance. For closed-box systems, there is

Time-domain measurement of vented-box loudspeaker system parameters

This work uses the pencil-of-functions technique, and shows that all of the loudspeaker system parameters can be determined straightforwardly from a single time-domain test.

Design of closed loop audio power amplifiers by means of an accurate model of vented box loudspeakers

The purpose of this paper is to analyze the stability of closed loop switching power amplifiers using an accurate model of a loudspeaker installed in a commonly used bass reflex enclosure instead of

Designing Loudspeaker Boxes

Most historical descriptions of loudspeakers (as we know them today) begin with Chester W. Rice and Edward W. Kellogg from General Electric [1]. They described what we know today as direct radiant

The Vented-box Effect on Thiele-small Parameter Loudspeaker

Loudspeaker testing is usually using the Thiele-small parameter. To see the effect of the vented box on loudspeaker quality, Thiele-small parameters in vented box boxes are used. Research carried out

Assessment of Nonlinearities in Loudspeakers Volume dependent equalization

Digital room correction of loudspeakers has become popular over the latest years, yielding great gains in sound quality in applications ranging from home cinemas and cars to audiophile HiFi-systems.

Design and construction of loudspeakers with low-drivers for low-frequency active noise control applications

The design and construction of small sound sources, as the elementary building components of a compound source for low-frequency noise control applications, is investigated. The need for small volume

Loudspeaker system figures of merit

The loudspeaker system small-signal figure of merit is a useful performance criterion that must be evaluated and used with some care. In practice, this figure of merit is significantly reduced by

A craft-project loudspeaker to serve as an educational demonstration.

A low-cost loudspeaker project/demonstration is presented here that is built from scratch using common household items and craft supplies, making it appropriate for a wide range of academic levels.



Performance of Enclosures for Low Resonance High Compliance Loudspeakers

This paper analyzes the low-frequency behavior of the vented loudspeaker enclosure and the pressure-tight closed box. Inherent interrelationships of the speaker-amplifier system Q, efficiency and

Loudspeakers in Vented Boxes: Part 1

An investigation of the equivalent circuits of loudspeakers in vented boxes shows that it is possible to make the low-frequency .acoustic response equivalent to an ideal highpass filter or as close

Direct Radiator Loudspeaker System Analysis

The low-frequency performance of direct-radiator loudspeaker systems can be accarately specified and is quantitatively related to the basic parameters of the system components. These systems function

Root and delay parameters for normalized Bessel and Butterworth low-pass transfer functions

Tables are given for the roots of the normalized low-pass Bessel and Butterworth transfer functions in both Cartesian and polar form. The latter form is especially useful when designing transitional
