This full frequency amplifier adopts brand-new TI TPA3116D2 amplifer chip, which can offer 100W powerful output and 90% efficiency.
Compared with other similar products on the market, it also uses a NE5532 buffer op-amp to achieve more powerful performance.
Its super mini size can be easily hold by one hand, which will be a good match for your desktop.
Power supply (not included, search ASIN: B074J81XRB to get one): DC 8-25V; at least 3A; higher voltage and current within the limitation would bring higher power
The subwoofer version (search ASIN: B072KDNW3F / B071GL4C9V) is used for a subwoofer, while the full frequency version is used for a normal speaker (please note it is for one single speaker, not a pair. So if you have a pair of speakers, you should buy two full frequency amplifiers).
