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

This amp was purchased to power a Dayton BST-1 Bass shaker. It does it with out a sweat. It is used on a sim racing cockpit under the pedals. It never goes over half as the rig would just vibrate to much. Perfect when using Simvibe software on PC, clean sound and very powerful. I have just got another to go under the seat, so two amps, 2 Dayton 50watt BST-1 bass shakers. Perfect combination. Would easily recommend for Bass shakers. Cannot verify for music as not tested, used for that.

This is the second one of these little Amps I have bought. The first one was to run four base shakers in my cinema room seats. It did this perfectly on a low setting too. My main £500 subwoofer amp stopped working a couple of weeks ago and had to go off for repair. With the Christmas period coming up I didn't want to have a none working system, so a bought one of theses again as a temporary measure... Running two 12 inch subwoofer seems easy for it, the system is now putting out bass that I can't tell any difference between this little amp and my big £500 amp. It's not even stretched, it's on about 25% volume. If I knew what these little guys are capable of I would have never have invested in the expensive one. A very impressive little amp for the money.

Great build quality and performance is good. I have a KEF home cinema sub with 2 drivers that blew its amp and this was my solution. Initially I wired to both drivers (into 4 ohms) but noticed clipping/diatortion in this use case. This is fair enough as the amp is 200w rated and the double sub originally ran on 2x250w amps, so I wasn't expecting the same output. However it handles it's power much better at 8 ohms with just one of the 2 drivers connected (so the other moves passively which is fine). In this config it produces a quality output which is fast and clean, but also can run higher levels in this single driver use case. It's producing comparable power and quality to the (over spec) original dual amp, at least for my needs in a medium sized lounge setup. So, certainly a strong option for any single driver sub up to 10" but don't overdrive it as the 200w is likely peak and not sustainable for more demanding configurations (bigger or dual driver units). Considering the cost of fixing the original amps is around 200-300 this is exceptional value for money and very easy to setup. The crossover control is also smooth and effective. You could easily set and forget this device inside a sub cabinet if you wanted to, as it's small and doesn't run too hot either.

Excellent little device for home theatre. My active LFE sub was overheating so I junked the built in amp and wired this in its place. It sits externally to the cabinet. Got it plugged in to an RF socket to turn it on/off as there is no signal sensor for auto switching. Sound is every bit as good as the original product and it seems to coast along at half power - the switch mode power supply provided hardly gets warm. Very pleased.

I somehow blew the amp of my van's Edge 10" EDBA active subwoofer. Despite optimistically swapping out some capacitors it was beyond my skill to repair. It seemed a shame to throw out the whole unit, so snipped out the speaker wires from the amp circuitry and threw the circuitry away. This Fosi TP-02 subwoofer amp drives the "now passive" (4 ohm?) Edge 10" speaker nicely. The Edge speaker wires connect to the two passive sub output posts on the back of the fosi amp. I now have it installed on a home sound system. I have the volume only a "third to half" of the way up and it is more than enough thrumping bass for a 5m by 5m room using the supplied power supply... any more on the dial is overpowering despite the the amp's power (200W "max" or 150W rms at 4ohm according to manual) being much lower than the speaker unit's original active rating (250W rms)... most use cases will not need to drive the speaker at anywhere approaching its maximum capability. Unlike another reviewer, the unit I was supplied with has the two dials, one for volume and one for subwoofer frequency as shown in the product description. To my ears, feet, and chest, the amp provides the warm tones and thumping bass I'm seeking and the frequency dial is to me vital in amplifying the frequencies I want depending on the music I'm listening to. I'm no audio expert so take this all with a pinch of salt. Well pleased with the amp and salvage of a piece of kit otherwise destined for landfill.

It's amazing. Used with an old passive subwoofer and the results are quite astonishing. I'm hearing things in the bass I've never heard before. All without distortion. Just pure bass. Thinking of buying another to replace the amplifier in my other subwoofer because this amplifier is better.

Amazing mini amp right here, works great on small subs that can take more wattage, this sub in the video is a 600w 8” boss audio sub, also bought here on Amazon, but the mini amp is really able to push good power to the sub even at low sub volume and frequency, and makes good sounding bass, no rattling or anything, just good clean, deep bass. I would 100% recommend for anyone interested in starting a room audio setup or home theater!

Nutze den Verstärker für 2 Bass-Shaker von Reckhorn im Parallelbetrib (4 Ohem). Funktioniert gut und die Leistung ist mehr als ausreichend.

Acheté pour amplifier le son de mon ancien mais bon actif subwoofer d’une vieille radio que je comptais jeter , suis tres content du résultat.

Ok i have now had my unit for almost 3 years powering a buttkicker mini in my sim rig and i really cant put it over a third as it rattles the whole rig with zero problems have a m04 too and that doesnt even compare probably getting another of these to replace the m04 highly recomended although i would not really get it for anything that needs more than 100w rms @ 4ohm i havent tried it with 2 ohm but it would raise distortion and wont get more than 108w from the power supply anyways so yeah 100w 4 ohm load perfect

This little ripper replaced a home-built subwoofer theatre amplifier that kept our movies “thumping” for over 20 years. It weighed about 4 kg with a massive torroid coil transformer feeding the amplifier push-pull circuit. No matter what hubby did, he could not get rid of the low frequency hum when no input signal was coming in from the Yamaha theatre receiver sub output. Apart from that, it thumped the passive subwoofer speaker for two decades. We decided we needed a replacement for “old hummer”and chose this unit. It arrived and I was a little taken aback - it is 1/4 the size of the previous amp. I wasn’t sure what to expect. Needless to say, I need not have worried. This little unit packs a massive punch into the 8 inch, 6 Ohm subwoofer speaker and when there is no input, it is as quiet as a church mouse. Bye bye humming... We have to have the FOSI set at about 1/3 to 1/2 volume otherwise the sub overpowers the rest of the theatre sound and starts rattling our French doors leading into the theatre room. I get that it is new and you can never be assured of the longevity, but the quality from the outside looks and feels good and the output at a low volume setting is simply amazing - despite its miniature size. Clear and concise. And no idle hum. :-) Long may it stay this way!
