Hello !
I would like to build a subwoofer, and need some advices ! I'd like to make something like the Adam t10s, the goal is to hear sounds at 28hz.
What interior design is the best ?
There are some small and cheap class D amplifier in aliexpress, what do you think about that ? It is ok for me if the amplifier is external.
It will be used in home studio, with Adam a7 satellites, at low and medium level. No need to be extra loud, I prefer sound quality than power.
For an other diy projet, I use a little cheap (16€) class D amp for a guitar cab I made, and I have to say that it works pretty well.
Thanks a lot in advance for your help !

This may be one better suited for the subwoofer section.
Some things to note:
1. For a given driver size, efficiency scales strongly with Fs. IOW, drivers that go deep are not particularly efficient and vice versa.
2. If maximum bass quality is desired,
a) go with a closed box design (don't worry if the response drops on the low end - chances are that room gain / boundary gain will help you with that, and then the more gentle dropoff will integrate better compared to a BR design)
b) use at least two subs in locations that do not excite all the same room modes for a better chance of evening out the in-room response
c) take measurements and apply DSP room correction.
3. Do not underestimate how insensitive human hearing is down there.
4. Subwoofer plate amplifiers generally come with useful functions already built in, like an adjustable lowpass and a phase control.
5. If there is any type of device that can use a balanced input, it's a sub.
