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

## Questions & Answers

**Q: can i use a 48v 5 amp power supply?**
A: yes ，you can，in fact i used 48V 6A is OK！but ，you want support a passive Sub as 8‘ or 10’ about 200-400 watts is very difficult and sound no good!  If you like low bass,I suggest you buy power Subwooder, because” good Bass”is very expensive

**Q: can i use a 24v 10 amp power supply?**
A: Yes, But pls check your subwoofer power , and our A3001 package with DC36V power adapter,pls know it,thanks

*by S***E on 19 April 2024*

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.
