Fosi Audio TP-02 Subwoofer Amplifier Home Audio, Mini Bass Amp Mono Subwoofer Amp, with TDA7498E Chip 220W Volume and Frequency Control, for Powered Passive Subwoofers Bass Shakers

Overall its quite good actually. Looks sure need improvement as silver bolts with dual rotation dial infront doesn't look elegant.Power:- it handles quite a big watt number range(220w max) but do remember the power supply in box is only upto 100w so to reach that max you need to buy new power supply so extra spending there. Still for 100w, i just listen at 30% volume as its that powerful. I have connected it with Bia Acoustics 8" Sub and just at that volume it sounds elegant and pleasing with enormous deep bass. I really like it. For medium size room just that much power is enough so think what would a full volume cover let alone 220w psu. So overall its amazing little device.Ports:- Has 2 way binding posts at back, i am using bare wire 1.5 sqmm(around 16 awg) to connect it directly to my sub as i don't like extra hanging wire and didn't want to cut my expensive ofc cable from dhivis. And that wire just barely went in so do remember that.Freq Range:- do note that TP-02 covers 20-120hz range shown on fosi webpage but amazon webpage shows 20-200hz. I confirmed with fosi team about this and they said unit as a whole covers 20-120hz but freq dial infront covers 20-200hz. Well thats confusing now. Would have been nice if freq dial had numeric markings on it.Comparison:- so comparing it with plate amps i would say its versatility and simplicity to just drag and drop, plus connect to any sub just makes it better option over plate amps. Also it doesn't lack in any way compared to AB sub plate amps. There is no noise at all when idle and sounds amazing. Plus consumes less power than class AB amps so its better for environment and budget. I checked with smart plug and it showed 20w while playing so good, if measured wrong then still it won't be much more than 30w as class D amps are power efficient devices so they are gaining more popularity now while still covering beautiful audio quality provided by AB amps.Also its cheaper in price also as recently it hit ₹5699 price mark. So save it cart to catch that deal when it comes back around.

I am using this subwoofer amplifier (Fosi Audio TP-02 TDA7498E Subwoofer Amplifier Mini Sub Bass Digital Class D Integrated Subwoofer Amp 220Watt) as a separate amplifier for driving my 10 inch passive subwoofer as my av receiver's subwoofer port is not working. This amplifier provides amazingly powerful sound output, and I think it can also drive a 12 inch passive subwoofer. Although it is a bit expensive (my purchase price was Rs. 7300/- approx.) but the sound quality is very good. I am totally satisfied with this product, now I have been using this for almost an year or may be more.

Very powerful subwoofer amplifier. Used in JBL HT 1S Dual 12 inch 100 W × 2 Passive Subwoofer (THX Certified, Made in Denmark) in parallel connection.

Look wise very small, it's was a dinamite 😍😍😍😍

Decently enough for the home purpose. It's easily driving my 12 inch Kenwood traditional car subwoofer box. Amp connected to my Denon AV receiver.

I've been using the Fosi Audio TP-02 since December 2024, and it's been a fantastic upgrade. I installed it as a replacement for the original amp board in my Polk DSW 550 subwoofer after it developed issues. Paired with a 24V 10A power supply, this amp delivers exceptionally clean and tight bass — far beyond what I expected at this price point.The performance is simply impressive. The bass is punchy, well-controlled, and adds real depth to my home audio setup. It's silent when idle, runs cool, and integrates seamlessly. No unnecessary features — just solid, reliable amplification.I'm genuinely happy with this purchase and highly recommend it to anyone looking for a budget-friendly yet powerful subwoofer amplifier. It brought my old subwoofer back to life with new energy!
