Great Product.
This thing shakes my room. Awesome, great for passive subwoofers to make it active.

After doing some research, I picked this subwoofer amplifier because it comes with the best stock power supply when compared with competing units within its price range. So far, I'm quite happy; I currently have it paired with a "broken" (bad plate amp) Martin Logan Dynamo 700W, 10" subwoofer. While it isn't rated for as much power as the stock plate amplifier (~200W versus 300W), it seems to have no problems driving it; fully-cranked there is just clean and loud bass. I'd imagine you could rattle a room a bit if you paired it with a larger/ported subwoofer. What mostly differentiates this from other monoblocks is the inclusion of a "SUB FREQ" knob. This effectively lets you set your cut-over frequency without requiring a DAC or some other type of EQ module; since my main speakers perform quite well down to about 45-55hz, I keep the SUB FREQ at a level where the sub is only producing notes at/below that range. For a basic 2.1 configuration, this function removes the need for additional equipment/cost. I would highly recommend this unit for anybody looking to breathe life into an old subwoofer. The cheapest subwoofer sold by Martin Logan today goes for $600 new. I found mine from a local electronics recycler for $130 and spent $20 in parts plus the cost of this amplifier to get it all working. The value proposition these little class D amplifiers provide is fantastic whether you have an unpowered sub, a powered sub with a bad plate amp, or if you want to build a subwoofer from scratch. Time will tell the longevity these units provide; if it lasts, i'll be sure to buy another one if I decide I want to add another subwoofer to my rig.

J'ai commandé cet ampli pour me faire un petit caisson de basse maison. Il rempli largement son travail. Je l'utilise pour une pièce d'une quarantaine de mètres carrés. Il est connecté à un sub de 250W RMS en 4 Ohms. Pour résumer, idéal si vous avez un sub passif et pas spécialement l'envie de le changer par un actif.

Ho preso questo miniamplificatore in classe D senza grandi aspettative conscio della reale potenza. L'alimentatore è da 35V5A in grado di erogare al massimo 175W che nel migliore dei casi si traduce in 140W effettivi su 4Ohm. L'ho preso per alimentare un subwoofer della AUNA che aveva lo stadio di amplificazione difettoso. Questo amplificatorino lo alimenta perfettamente e risulta perfino sovradimensionato rispetto a quello originale. Rispetto all'originale (di pessima fattura!) ha bassi molto più secchi e meno roboanti. Sicuramente più musicali e meno da effetto cinema (anche se io lo uso in ambito HT). L'ho provato anche come amplificatore di un canale frontale e si comporta davvero molto bene se non per un leggero fruscio alle alte frequenze che però leggo essere una caratteristica degli amplificatori in classee D economici. Rispetto al Denon (usato da pre) è più analitico e tende a mostrare maggiormente i difetti delle tracce audio. Sono tentato di prenderne altri due per verificare come si comporta in una scena stereofonica e provare ad alleggerire il carico al Denon.

Great product, using it to replace the panal amp in my B&W ASW-2500 subwoofer and im finding it a great substitute. As a bonus the controls are more excessible now than before. As i would have to crawl in behind the sub
