The use of loudspeakers can become a nuisance to neighbors if the building is not sufficiently insulated. To limit the transmission of vibrations to the structure of the building, an elastic support must be inserted between the enclosure and its support. The difference between bipolar and dipole is at the phase level: speakers on both sides of a bipolar speaker work in phase, while a dipole speaker has a phase reversal between speakers that reproduce the same bandwidth (this aims to increase the envelope at the expense of accuracy). Dipole speakers are designed for THX systems. Phase reversal also has the effect of causing an acoustic short circuit in the low frequencies, because wavelengths and radiation cause acoustic opposition of the low frequencies. One solution to maintain a good bass level is the semi-dipole speaker, which consists of maintaining the unipolar principle for low frequencies with one or more speakers and keeping the rest of the spectrum in the dipole typology for packaging. Thus, we preserve all the advantages of this solution, since the bass is omnidirectional (360° radiation). Some speakers allow you to work in both modes, with a switch to switch between them. Speaker combinations are a common and normal practice in the world of sound systems.
On the other hand, for high-fidelity listening, it is a practice that must be avoided: multiplying speakers and therefore sound sources without controlling their transmission range creates interference detrimental to the quality of sound reproduction. The monitor is a very high fidelity speaker, the main feature©of which is a©linear©response in frequency©and intensity©. ©© These speakers are typically©©used in©the studio to get an objective preview of a mix. Contrary to popular belief, it is not just a matter of “recovering” the rear shaft, otherwise the vent would redistribute the same sound spectrum as the speaker, which is not the case. The bass reflex system can be considered as a mass-spring-mass system. [20] According to this analogy, the speaker has a mass (diaphragm + coil) and a spring equivalent (suspension + spider). The addition of a resonator connects the mass of the speaker to a new mass (air in the vent) through a new spring (the air contained in the volume of the load). Air is both a spring and a mass, but the one contained in the vent is considered only a mass, because the small surface of the vent gives it a high speed and therefore inertia [20]. On the contrary, the air contained in the volume of the case is considered a spring due to its relatively large volume and low speed. There are also tripolar speakers, but this solution is less common. The price of speakers is often very high, so it`s tempting to make them yourself to save money.
This is often a bad idea, as the cost price is rarely attractive in terms of value for money. Personal achievements only make economic sense when it comes to putting your possible ideas into action or creating models that fit you perfectly (available space, integration into a decoration, certain techniques). On the other hand, the joy of self-construction is to be considered, if not economically quantifiable. Take, for example, the case of a speaker of sensitivity at 97dBspl/1W/1m, we deliver it with a signal of 512W, the spl level at© 1m is then 124dBspl. If we set ourselves© at 8m, the spl level is 106dBspl.
