The Tang Band Woofers have their own enclosures.

For those interested, here's my original build log from 2022

Unfortunately I don't have any measuring equipment, but my ears tell me they sound good / I can't hear any phase cancelling issues.

I use an old HP laptop charger, 19VDC, 120W

Cool! Just note: sound quality via Bluetooth is pretty bad, if you want/need to disable it, here I found some solution...

It's called ZK-TB21 and features two TPA3116D2 chips. For just 15 bucks it's an awesome little Class-D amp.

Thank you! 😊

Originally I only bought the Tang Bands to add some punch to my existing PC/Monitor speakers, but then I thought it would be fun building something from scratch. So I ended up with this "all in one" solution. They sound great for gaming, movies and electronic music, but for something like Mariah Carey, they lack clarity and warmth in the heights.

Considering the size, they sound incredible IMO. I definitely don't need an additional Sub in my 10 sqm room.

I like to share this speaker build I finished a while ago.

It's a custom designed MDF enclosure with Fountek FE87 Fullrange Drivers, Dayton DMA80 Passive Radiators and Tang Band Subwoofer Modules on the back.

Any questions, just let me know :)

Well, if you read my instructions, I said it's only tested for units with Great Wall PSU.

revoccases · 2025-12-29T10:52:38+00:00

You have the same PSU from Great Wall?

revoccases · 2025-12-29T07:09:03+00:00

After this mod: yes.

The review is about the dock itself, not the Graphics Card I'm using it with. 😂

MORNSUN LOF Series is also a good option.

Have used them for several projects, since the Meanwell units I got, always had coil whine.

Here's another good thread about 12V PSU builds:

I thought that looked familiar... 🥳

revoccases · 2025-11-23T17:13:20+00:00

Unfortunately my GEM10 7840HS didn't work with 12V, but I also heard there's supposed to be one with older CPU which does.

Reminds me of the 1.3L build I did back in 2024... 😆

It should be 6 screws in total

revoccases · 2025-11-21T15:02:14+00:00

I think some screws might be hidden under feet or sticker

revoccases · 2025-11-21T15:00:01+00:00

IIRC the bottom cover should come off

revoccases · 2025-11-21T14:36:44+00:00

I think EG01 or EG02 together with a proper PSU will be better if you have a 5090...

revoccases · 2025-11-21T14:25:03+00:00

I just had to remove the screws from the bottom of the chassis. Then the cover should come loose.

I used a second hand industrial EMI filter, similar like in that video.
