Noo They are covered from tha back

They are not tweetwers and they are not covered from back...but they should be

Those are Twitter

You can put medium and tweeter in the same chamber, but the woofer always need to be alone.

@@issoulescondes3913 You can install tweeter in the same box when it is "closed type" tweeter (sealed from air entering from the back). He did it wrong in the video as he used "non sealed" tweeters. They will act pretty much as passive radiators as pressure from woofers/mids can move tweeters cone from inside the box. You can see them moving out of phase when bass hits. Its going to distort sound and probably will damage tweeters as well. You should seal those manually by making small enclosures as others said.

Думаю, в данном случае провалы громкости на мощных низких частотах это проблема усилителя, а идея фазоинвертора была не такая уж и плохая, если была цели достичь максимальной громкости самых низких частот (с пассивным излучателем такое не прокатит). Внутрь лучше не ложить особо ничего звукопоглашающего, ведь это повлияет на вес подвижной системы (если такой широкополос как 10ГД-63К, то лучше использовать синтепон в ЗЯ, чисто для поглощения внутренних резонансов), максимум обшить стенки поролоном, лучше даже акустическим...

Tenho dó dos vizinhos deste cara, não é fácil morar perto dele, com tanto barulho assim...

Start by making sure the speakers (drivers) match in sensitivity (SPL, measured in dB). This is more important than wattage, it will make sure that your speakers are at an even volume. You can use any amp with any speakers, but usually the amp is lower powered than the speakers. If you are using an amp with more power than the speakers, just be sure not to turn it up too loud. You will also need to design an enclosure that has the correct internal volume (i.e in Litres) for your drivers. if you google 'speaker box enclosure' there are calculators that will do this for you.

Nhìn cách đấu nối là biết dân mù âm thanh rồi..loa to như thế mà k đấu qua phân tần hay tụ cho trép gì cả

@@HienNguyen-ip8hy Tào lao ông ơi, làm gì có treb mà cản tụ, 2 cái loa vệ tinh là toàn dải chứ không phải treb, còn cặp bass 20 cắt tần sẵn trên mạch rồi nên phân tần là vô nghĩa.

trebl

power supply

Maybe in online shopping

🤣

it will keep constant voltage supply to an amplifier. When battery discharges over time, its voltage going to drop. Less voltage to an amp = less power output from it.
