## Description

Fosi Audio V3 Stereo Power Amplifier Home Audio 300 Watts x2 TPA3255 Class D Mini Speaker Amp 2 Channel Audio Component Amplifier for Passive Bookshelf Tower Speakers for Desktop Home Theater : desertcart.in: Electronics

Review: Ample power for tower speakers. - Sounds good for the price. It powers Elac FS58 3-way, bass-reflex floorstanding loudspeaker with a recommended power: 20 - 180 Watts. The speakers are loud and clear without any clipping.
Review: This is essential if you want to increase power or connect additional speakers. - This amplifier is a must-have if you're connecting multiple speakers, as I have, or simply setting up a stereo system. I’ve been using it as a power amplifier for my Atmos speakers in my dedicated home theater. My AVR has pre-outs, so I connected the Fossi amp to the AVR and then to the speakers. It’s doing an excellent job. I’ve been using it for over 7 or 8 months, and I haven't experienced any issues. As a driver for Atmos speakers, it easily handles both heavy bass and high frequencies. I have not tested it for stereo listening. Overall, it is great value for the money.

### ⭐⭐⭐⭐⭐ Ample power for tower speakers.

Sounds good for the price. It powers Elac FS58 3-way, bass-reflex floorstanding loudspeaker with a recommended power: 20 - 180 Watts. The speakers are loud and clear without any clipping.

### ⭐⭐⭐⭐ NOT AUDIOPHILE, BUT GOOD VALUE
*by R***U on 28 January 2025*

Well built.I bought it as a second amp for a new setup . Can deliver adequate power to my ELAC 50 W speakers without any issues. Lacks warmth or fullness. If you are used to hearing on good quality amps, you will certainly feel the difference. But for the price it packs enough punch for a basic setup. No noises.
