I agree, it’s noticeably stronger on the recording, this is due to the distant location of the microphone and the side walls of the furniture; in open space it sounds better live.

All work on the channel was done out of personal interest in audio systems, it’s like a hobby. A lot of time is spent on producing a finished project. For a person who just wants to make acoustics with his own hands, there is no particular point in assembling it himself, since it requires a lot of tools, time, skills, and money for good components, especially if you want to make a beautiful and effective device.

To assemble a Bluetooth speaker using a 12" subwoofer, it will be heavy in any case, especially if the speaker requires a large internal volume. For example, on my RU-vid channel there is a speaker with a jbl 12" subwoofer, it weighs about 42 kg. this is a lot, you need to carry it in 2 and carry it only in the trunk of a car. For a portable one, I think the maximum size is 8", as for the power of the tpa3116, it approximately needs an 8" subwoofer, they are usually about 100w. Car subwoofers require more power around 200w and above, you can consider tpa3255. About the speaker parameters, I agree that it will be easier to assemble, knowing the parameters, you will be able to understand what internal volume is needed for the speaker, what design is suitable.

For the best efficiency of designing your Bluetooth speaker in an open environment: a closed box, a bass reflex or with a passive radiator, you will need to at least measure the impedance of the speaker in the box. Based on the result, you can understand what type of design is better suited; if it’s a bass reflex, then it’s better to bring the port forward. A closed box will play well if you buy a good speaker with low FS, a good magnetic system (full quality factor), with a small internal equivalent volume, then you can get low tuning in small dimensions.

If you use CO 08 Evo, it has fs 41.9Hz, Vas 20.7 liters. Let’s assume you assembled a closed box, square, then it will be approximately 28 x 28 x 28 cm, this is inside the case, taking into account the small volume displaced by the speaker itself, i.e. you take into account the thickness of the material and can imagine the future size of the speaker, or rather the compartment for the subwoofer. In this case the resonance will rise to 58-59hz. This is normal for clear and correct sound; you won’t hear low bass in the open air. The bass reflex can be adjusted to approximately 39-41Hz. Just use the program to see for yourself how long the port will be needed, whether it will fit inside the case or make a port along the wall with a 90-degree turn.

@@DIYAcoustic thanks for your Response ! So do you think its stupid to build with a speaker if you dont have the parameters ? I dont want to throw them away or build cases i cant reuse for anything u know. I dont need ultra low bass, 50hz and above would be fair enough

Of course, you can assemble without parameters, but the result can be very bad, for example, you assemble a case, and the VAS dynamics are very large, in the end you will get a very high setting, etc. Of course, it may be that you get a good result the first time, in fact, you can configure it after assembly if you make a bass reflex port using a port in the form of a sewer or some other pipe, selecting different lengths by ear, or use a smartphone microphone in a spectrum analyzer application.

Coleciono projetos principalmente por encomenda ou para pessoas que conheço. Se você quiser comprar algo parecido, então você precisa escolher na sua região, a entrega do meu país vai ficar muito cara e a embalagem pode ficar danificada. A única coisa que posso te ajudar são as dimensões, tem um desenho em Corel, mas usei um alto-falante médio do microlab h600, você simplesmente não pode comprar isso, então ainda terá que mudar alguma coisa ou usar outra coisa .

@@DIYAcoustic tudo bem. Obrigado pela resposta,. Faz sentido

From 1 hour to 10, depending on the volume. At medium volume about 4 hours.

You can find it by name on Aliexpress. Some links no longer work.

But can you tell me what is company name of the sub woofer please

Aiyima subwoofer 5,25 inch, 40w

Thanks

I don’t sell bluetooth speakers, I only make them to order in my region, because they are more expensive than factory ones. If you want something similar in design, you can contact a specialist in your region. You can find out the price approximately by counting the components you need.

I'm from Russia

Oo

I think it’s better and easier and cheaper for you to make a similar Bluetooth speaker in your country. If you need the dimensions of the parts, I can send you the file by email, write to me, in the channel description there is an email for communication, only you will take into account your speaker sizes, mounting for the amplifier and more.

В описании канала есть почта.

मेरी कई परियोजनाएँ चालू हुईं, लेकिन मेरे क्षेत्र में। आप वीडियो के नीचे विवरण में घटकों के लिंक से अनुमानित कीमत की गणना कर सकते हैं, लेकिन मेरे क्षेत्र के बाहर तैयार स्पीकर बेचने का कोई मतलब नहीं है, क्योंकि डिलीवरी बहुत महंगी होगी। आपके लिए अपने निवास क्षेत्र में खरीदना या बनाना आसान होगा।

Tôi không hiểu ý bạn lắm vì người dịch, nhưng trong bản sao của tôi, loa tần số cao được kết nối với kênh 1, loa tầm trung được kết nối với kênh 2, bảng phát trực tuyến được đặt ở chế độ đơn âm.

I'm actually thinking about it too, but now I understand the concept.
