This thing bumps. I’m powering it with a Wuzhi ZK-LT21 (30W for the sub) the other two subs in the photo are okay but even with the small form factor, this onkyo outperforms. Pair it with some speakers that can cover good mid range because this sub will cover low end 50-200Hz. Has a crazy spike at 51Hz and a heavy dropoff below that. That spike really comes out in those dropping bass lines.

Awesome rich low bass. I’m using the ZK-LT21 to power it. Has a long port that does get some chuffing or wire vibration in higher volumes. I ordered a second sub and tried other versions. Out of all the mini subwoofers on Ali, this one has the best sound.

Упаковка – выше всяких похвал. Звучание немного разочаровало. Ожидал большего. Также смутили резонансное дребезжание. Придётся дорабатывать пластиковый корпус, снижая вибрации. По задумке, хочу разместить внутрь спинки сидения автомобиля, есть там место. Да и пробные подключения показали, есть в этом что то…

Decent amount of bass from such a tiny speaker, the speaker driver itself has a lots of potential but unfortunately with this enclosure the port has a huge amount of port noise even in low volumes. It defenitely needs a new box design so the next step is tó get the speaker out of the box, measure the T/S parameters and design a new box with a port that is wider.
