[@RandomAudioGuys]

I just found your channel Donny, and you did an amazing job of crafting something that looks retail, I love your use of the 3d printer. You made jigs with it that helped finalized a professional look, I was worried that it would be a overuse of 3d printing when I saw the title, but you integrated the 3d printer in a way that it should be used, we all know the look of 3d printed parts is not a finish that gives a production part look. The ports were masked in the back allowing them to do their job without showing up to the eye. You may want to consider giving the front ports that show an acetone bath, It helps give a production look to 3d printed parts and would only need done to the piece that shows to the eye. But I wanted to say, you did an amazing job , and I am about to use a set of Focal Slate series speakers for a similar product and kudos for doing an awesome job in inspiring many others.

[@Danielddiniz]

You’re so greatly talented, man, congratulations 🏆

[@DGen.X]

Yep, your classic type of building a bluetooth speaker here in your KZbin channel! AWESOME! The combination of that bluetooth amp and the driver are perfect! Sound quality is amazing, great build sir Donny Terek.👏👏

[@DonnyTerek]

Thank you so much! Kindly appreciated.

[@user-rj4ly9qu6j]

Very nice finishing

[@wattspeakers]

Wow! Incredible build, so much attention to detail and the craftsmanship was meticulous. Your camera work and video editing are... Well to say incredible would be an understatement. The sound sampling was top shelf, the sound was excellent. But the part I liked the most, was the ported, powered portable speaker system that sounded impressive. Gorgeous work of art, with that embossed handle. Amazing. Really really good job all the way around.

[@DonnyTerek]

That's awesome, I love the attention to detail! How loud is it? Did you test the decibels? It seems that the "22uF 100V Electrolytic Non-Polarized Crossover Capacitor" and " Dayton Audio CX120-8 coaxial driver" are sold out. Do you have any recommendations for replacements?

[@DonnyTerek]

Thank you! Sorry for the late reply, but it seems both are back in stock now.

[@DonnyTerek]

[@bhawnajarwal]

made a solid sistem no compromise to quality too good work exilent

[@Schjoenz]

I really wanted to know how to get those numbers like internal volume, port size and whatever that is. All I know is how to connect the amplifier, power supply, speaker and everything about electronics. But the box sizes, air volume, and all the physics of sound wave is something I have zero knowledge. Where can I find tutorials for these and what terminologies should I use?

[@HVACSAN]

Nice bass and sound quality!

[@natomale]

Hi Donny, how did you calculate your needed power? Your battery pack is 3* 3.7v 3.4ah - Your amplifier can receive 12-24v and can give 2*100w - Your speakers can receive 40w

[@DonnyTerek]

Hi! The actual power output on the amplifier is more like 2*25W if not less. The battery pack is roughly 35 Wh of capacity so it is suitable for the power needs of this amplifier.

[@ricardoandres1427]

Hola. Consulta: dónde compras el kit de altavoces? Por lo que he visto en tus videos, me quiero animar a fabricar uno. También soy amante de los parlantes y los colecciono. Excelente trabajo y muy prolijo. Te sigo desde ahora en KZbin. Saludos desde Chile.

[@DonnyTerek]

Hi! Had to translate your text. You can check the description for links to the parts.

[@puresoulg]

Where can I purchase the Speakers amp and elcteoncs ? Approximately how much do they run??

[@DonnyTerek]

Hi, sorry for the late reply. I have just finished writing down every component in the description. The battery life is quite good, around 8 hours on mid volume.

[@denisbritorodrigues]

Mto top parabéns!

[@ford1546]

with 11v batteries, you will not get that many watts out of the amplifier! and with so few batteries, batteries don't last long. I think the JBL extreme 2 has a 10 Ah battery compared to the 3 Ah that you have
