You cannot bring a pair of big box speakers to use for the building&#8217;s sound system, but must be ceiling speakers, column speakers, box speakers .. and vice versa. Each sound system such as stage sound, restaurant sound, cafe sound &#8230; will have speaker devices designed specifically, so that it is most suitable and effective.<\/p>\n<p>Never consider the choice of speaker installation redundant, roughly. One day you will have to regret if you do not prepare yourself with those basic knowledge. Not only does it cost money, but the effect it brings will not be what you want.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"1_Select_the_type_of_announcement_speaker\"><\/span>1. Select the type of announcement speaker<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Speakers are an indispensable device in the notification sound system. To meet the needs of many different sound systems, the speakers have also become more diverse. Each system has its own specific type of loudspeaker.<\/p>\n<p>If your speakers are installed in the hallway, where there is a small area, there is probably no more suitable type than ceiling speakers. Space saving, soft, clear sound quality, not too loud causing jarring, discomfort for residents. More importantly, it matches the design of the corridor, creating an airy and beautiful feeling for the building. You can also choose a loudspeaker for the rooftop area of \u200b\u200bthe apartment building to make the general announcement resound.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"2_Select_a_reputable_speaker_company_for_the_system\"><\/span>2. Select a reputable speaker company for the system.<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>In terms of long-term reputation, it is probably difficult for any audio company to surpass TOA. Although there are many major audio companies in the world such as BOSCH; ITC; EV\u2026reliability and audio output are also outstanding. But TOA is still the most popular choice trusted by customers. TOA can meet all customer segments from low cost to high, but the sound quality is extremely good.<\/p>\n<p>Choosing a notification sound system, we should choose a sound company that provides all the equipment in the system. Because when manufactured with the same company, the devices have been calculated by sound engineers to match, match between devices to create a system. Using equipment from manufacturers to mix it will not be smooth and sometimes create a limp in the installation process. And should choose genuine distribution agents to avoid encountering counterfeit goods of poor quality. Do not be greedy and ignorant to choose floating speaker devices only through mere advertising.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"3_Select_the_required_number_of_speakers_in_the_system\"><\/span>3. Select the required number of speakers in the system.<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Choosing the number of speakers will become simple if you have a basic understanding of the installation distance and capacity of the speakers. If the area of \u200b\u200b\u200b\u200byour apartment speaker system is larger, the more speakers need to be installed, the thickness of the distance between the speakers also depends on the installation space. On average, if it is a ceiling speaker, the speakers will be installed about 4-5m apart (depending on the area).<\/p>\n<p>Selecting the number of speakers is also an important part of installing an apartment speaker system. If you think that the more speakers you install, the louder the sound travels, you are wrong. Aside from costing money, it&#8217;s not effective at all. easily tangled, the sound is overlapped, causing waste.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"4_The_best_and_reasonable_speaker_placement\"><\/span>4. The best and reasonable speaker placement.<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>The placement of speakers again depends on the area of \u200b\u200b\u200b\u200bthe sound used. In addition, it also depends on the speaker design, the architecture of your apartment building.<\/p>\n<p><strong>Example<\/strong>\u00a0: Ceiling speakers will be installed directly on the ceiling with a recessed speaker structure so that the sound bounces straight down to the listener. Box speakers are usually installed at extended angles so that the sound is spread to the correct listener position.<\/p>\n<p>If you are clever in choosing the speaker placement, you will reduce the number of speakers and save a lot of costs\u00a0installing the apartment speaker system.<\/p>\n<figure id=\"attachment_2589\" aria-describedby=\"caption-attachment-2589\" style=\"width: 800px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-2589 size-full\" title=\"L\u01b0u \u00fd khi l\u1eafp \u0111\u1eb7t h\u1ec7 th\u1ed1ng loa chung c\u01b0\" src=\"https:\/\/p69.com.vn\/wp-content\/uploads\/2022\/07\/IMG_20200801_120840.jpg\" alt=\"L\u01b0u \u00fd khi l\u1eafp \u0111\u1eb7t h\u1ec7 th\u1ed1ng loa chung c\u01b0\" width=\"800\" height=\"500\" srcset=\"https:\/\/p69.com.vn\/wp-content\/uploads\/2022\/07\/IMG_20200801_120840.jpg 800w, https:\/\/p69.com.vn\/wp-content\/uploads\/2022\/07\/IMG_20200801_120840-600x375.jpg 600w, https:\/\/p69.com.vn\/wp-content\/uploads\/2022\/07\/IMG_20200801_120840-300x188.jpg 300w, https:\/\/p69.com.vn\/wp-content\/uploads\/2022\/07\/IMG_20200801_120840-768x480.jpg 768w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><figcaption id=\"caption-attachment-2589\" class=\"wp-caption-text\"><em>Notes when installing apartment speaker system<\/em><\/figcaption><\/figure>\n<h3><span class=\"ez-toc-section\" id=\"5_Select_and_install_the_apartment_speaker_system_according_to_the_cost\"><\/span>5.

There are apartments designed with soundproof doors, which will limit the noise to create privacy for each apartment. With this form, we should use loudspeakers. Loudspeakers are designed to play at high frequencies, so the sound is very large and far away. In case the apartments are closed, they can still hear the announcements from the management.<\/p>\n<p>For apartments that use wooden doors or iron doors, we design ceiling speakers. Ceiling speakers have a beautiful compact design, sound coverage evenly. Because the sound dispersion is low unlike loudspeakers, the speakers must be mounted closer together, the distance between the speakers in the apartment corridor is from 8-12 meters.<\/p>\n<p>As for the stairs, you should choose a box speaker with a capacity of 6-10W. It is possible for each floor of the stairs to mount 1 box speaker or 2 to 3 floors to install a speaker.<\/p>\n<figure id=\"attachment_2591\" aria-describedby=\"caption-attachment-2591\" style=\"width: 768px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-2591 size-full\" title=\"C\u00e1c lo\u1ea1i loa s\u1ebd d\u00f9ng trong h\u1ec7 th\u1ed1ng \u00e2m thanh t\u00f2a nh\u00e0 chung c\u01b0\" src=\"https:\/\/p69.com.vn\/wp-content\/uploads\/2022\/07\/he-thong-am-thanh-thong-bao.jpg\" alt=\"C\u00e1c lo\u1ea1i loa s\u1ebd d\u00f9ng trong h\u1ec7 th\u1ed1ng \u00e2m thanh t\u00f2a nh\u00e0 chung c\u01b0\" width=\"768\" height=\"510\" srcset=\"https:\/\/p69.com.vn\/wp-content\/uploads\/2022\/07\/he-thong-am-thanh-thong-bao.jpg 768w, https:\/\/p69.com.vn\/wp-content\/uploads\/2022\/07\/he-thong-am-thanh-thong-bao-600x398.jpg 600w, https:\/\/p69.com.vn\/wp-content\/uploads\/2022\/07\/he-thong-am-thanh-thong-bao-300x200.jpg 300w\" sizes=\"auto, (max-width: 768px) 100vw, 768px\" \/><figcaption id=\"caption-attachment-2591\" class=\"wp-caption-text\"><em>Types of speakers that will be used in the apartment building sound system<\/em><\/figcaption><\/figure>\n<h2><span class=\"ez-toc-section\" id=\"Reputable_apartment_speaker_system_installation_unit\"><\/span>Reputable apartment speaker system installation unit<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Currently, there are many units on the market that <strong>install apartment speaker systems<\/strong>.
