Description

Subwoofer frequency control knob for optimal bass integration Extremely potent bass that conjures up thousands of waves With a maximum output power of 220W, it is ideal for large subwoofers TP-02 M04 M03 M01 V3 Mono Two V3 Mono Which type of speakers works best with the TP-02 Amplifier? TP-02 works well with most 2-8Ω subwoofers. Why does the TP-02 make serious noise when used together with a radio? The common feature of Class D power amplifiers is that they can cause serious noise when used with a radio, so we do not recommend using the TP-02 with a radio or too close to it. Why does the amplifier stop working after a period? And after a while it work again? The amplifier is in this case normally overheat protected, and the output power may have exceeded the designed range, so you can lower the volume a little and try again. Why isn't the powered subwoofer working? Connection: Computer (3.5mm Headphone Out) → TP-02 (Sub Out) → Powered Subwoofer. If the powered subwoofer has an LFE port, use a mono RCA cable.

    • An excellent, cost-effective product
I have a 7 year-old Polk PSW110 subwoofer. Recently, its plate amp failed. The amp, while easy to replace, hasn't been available for quite some time. I found one on eBay, untested with no returns, so I passed on it. I couldn't find one on Facebook Marketplace. I called the U.S. repair facilities listed on the Polk audio web site. They would all repair the plate amp, but the least expensive facility quoted $100 to evaluate (applied to the repair), plus parts, labor, and shipping, with an estimated total cost around $200. I can buy a new, fairly equivalent 10-inch subwoofer for $230, so going the repair route was not cost effective for me. Then I decided to "think outside the box". What if I got an external amp, I wondered. I did some searching, and came across the Fosi Audio TP-02, which costs only $70, so I figured I'd give it a try. I was able to bypass the Polk's plate amp quickly and easily, thereby converting it from an active to a passive subwoofer. I'm happy to report that the TP-02 is well made, compact, easy to connect, and easy to adjust. Most importantly, I am very pleased with its performance. It provides deep, clean, extended bass response, with extremely low distortion. It can put out way more power than I need in my moderately-sized listening room. Thanks to the TP-02's low idle power consumption, I leave it turned on all the time. When my receiver is turned off, if I put my ear right next to the subwoofer, I cannot hear even the slightest amount of hiss, hum, or buzz. I consider myself to be an audiophile, and I enjoy listening to many genres of music. If you're looking for an excellent, cost-effective way to bring a powered sub back to life after its amp bites the dust, the TP-02 subwoofer amp is the way to go. ... show more

    • Fosi, the king of kompact kool once again
I use this with the Fosi MC331 integrated via a 3.5mm plugged cord. It's a simple set up that sounds great in my bedroom system. This little sub amp plays very cleanly with all the heft and detail that Class D amplification provides, especially in the low frequencies. I have the volume set at 1:00 and the crossover frequency set at about 100hz. The input sensitivity is fine for matching the MC331 integrated. There is no phase switch, but switching the speaker wire polarity is the easy work around if needed. I didn't. My small subwoofer now blends so well with the main speakers. It's noticeably quicker than the old $450 Class AB sub amp it replaced. It can play the sub louder to impressive levels, and exceeds my need for power playing even the heaviest music. For those seeking serious bass from larger drivers will be disappointed. "This ain't that." The form factor is good and the unit is attractive... but not as attractive as the MC331 case. I hope Fosi considers putting this same package into the new style case for more design continuity. Still, the combo looks great to me. I'm happily filling my life with more music and Fosi provides a cool, convenient way to have high quality audio reproduction for modest prices. I operate this amp for 8-10 hours per day and it doesn't produce any heat due to the high efficiency and has no perceivable impact on my power bill. This is a great, affordable answer to those needing a modest subwoofer amplifier in a small package. After a long life of having high end audio products, I really appreciate the niche that these products fill. It's an exciting time when quality and attractive audio products are now available to more people than ever. And, listening to music makes us a little less crazy. Rock on and hug your mom. ... show more

    • Great amp! Great value!
Bought the TP-02 to replace a dead Klipsch SPL-120 subwoofer plate amp that went bad. This amp was easy to hook up after I added passive input to the speaker cabinet. Wow! This amp really provides plenty of power for the speaker and the crossover works perfectly. Very pleased with the sound and it saved me from an expensive repair or replacement sub. Great value! ... show more

    • Nice sub amp...
This Fosi Audio TP-02 Subwoofer Amplifier works great. It was much cheaper than a replacement amp for my sub. I bought this same amp a few years ago for my other subwoffer and it's still going strong.

    • Great Amp! Crossover could be more steep.
Great little amp! I have a powered subwoofer that had its amp go down. The cost of getting it fixed was well more than the cost of the TP-02, so I rewired the speaker to use this amp instead. Seems to deliver enough power for my kind of listening. 85db is as loud as I go. My only gripe is the crossover seems to use a more gentle 1st or 2nd order slope. At least that's what my ears tell me. I'd prefer a more aggressive one, but I made this work. ... show more

Works great to power my bst-300ex for my sim rig. I tried an aiyima a3001 before this which kept cutting out due to power protection. This one does not have that issue.
