Class D active subwoofer module, 200 W at 4 Ω High-performance active module in class D technology Variable low-pass filter: 40-200 Hz (18 dB) Continuously adjustable phase control 0-180° for perfectly matching it to the main speakers Line input, par. line output Integrated bass boost of approx. 3 dB at 40 Hz High power reserves Box Contains 1x Active Digital Subwoofer Module Review: Good bit of kit. - Replaced a burnt out Kef subwoofer amp, had to make a plate up to mount it as this amp is smaller. But it does the job well. Sounds very good and the auto power off works too. Definitely would recommend rather than throwing a perfectly good subwoofer speaker and cabinet away. Review: Great digital subwoofer amp - well designed and easy to fit. - This subwoofer plate amplifier does everything expected of it. It's neatly constructed and lightweight and performs well down to a satisfyingly low frequency level. I bought it to replace a faulty amp in an older Kef subwoofer which, through overheating over time, had burnt out some fragile capacitors. The Kef had a design fault that meant that, despite having a so-called automatic standby mode when no input signal was detected, it never actually switched the amp circuits off, thus producing constant heat. This, coupled with a very poor heat dissipation construction method, caused the components to fail and produced a well-known buzzing sound and no reproduction of audio. After two attempts to replace the faulty capacitors with no result, I decided to replace the whole amp and chose the IMG unit as the nearest match. The plate of the IMG is much smaller than the Kef original so I had to cut a suitable hole in the Kef plate (after dismantling all the original electronic components, which were now useless) in order to mount it neatly in the speaker enclosure. Doing this allowed me to make sure all electrical connections were safely enclosed, whilst also providing good ventilation to make sure overheating never reared its ugly head in future. Having installed the IMG plate on top of the stripped down Kef plate I now have a subwoofer that does exactly what I wanted, for a much lower cost than a brand new unit from Kef or Tannoy costing several hundred pounds more. The IMG has a genuine standby switch which really does reduce power consumption when no signal is detected - I can tell because it goes completely cold after a period of no usage. The sound is nicely balanced with the subwoofer output from my Marantz streaming receiver. Now I have the deep bass that my bookshelf speakers can't reproduce when listening to high quality audio or video. I recommend this unit. One caveat - it does produce an obtrusive hum if the output level is set too high - but I take this as a sign that I've cranked up the volume too high anyway. ## Features - High-performance active module in class D technology - Variable low-pass filter: 40-200 Hz (18 dB) - Continuously adjustable phase control 0-180° for perfectly matching it to the main speakers - Line input, par. line output - Integrated bass boost of approx. 3 dB at 40 Hz - High power reserves ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B008AVOSP4 | | Best Sellers Rank | 279,058 in Electronics & Photo ( See Top 100 in Electronics & Photo ) 2,873 in Car Audio Speakers & Subwoofers | | Colour | schwarz | | Compatible Devices | Personal Computer | | Country Produced In | china | | Customer Reviews | 4.1 4.1 out of 5 stars (98) | | Date First Available | 11 Aug. 2012 | | Item Weight | 1.05 kg | | Item model number | 32.0780 | | Material Type | Plastik | | Power Source | Corded Electric | | Product Dimensions | 8 x 17.8 x 20.4 cm; 1.05 kg | | Scale Length | inches | | Speaker Amplification Type | Active | | Wattage | 100 watts | ## Product Details - **Brand:** Monacor - **Speaker maximum output power:** 280 Watts - **Connectivity technology:** RCA - **Audio output mode:** Stereo - **Mounting type:** Tabletop - **Material:** Plastik - **Model name:** SAM-200D - **Speaker type:** Subwoofer - **Special feature:** Hochtöner - **Recommended uses for product:** For music players ## Images ![IMG Stage Line SAM-200D 280W Digital Active Subwoofer Module, 32.0780 - Image 1](https://m.media-amazon.com/images/I/91RkWXGgsjL.jpg) ![IMG Stage Line SAM-200D 280W Digital Active Subwoofer Module, 32.0780 - Image 2](https://m.media-amazon.com/images/I/71oOEtp8ZkL.jpg) ![IMG Stage Line SAM-200D 280W Digital Active Subwoofer Module, 32.0780 - Image 3](https://m.media-amazon.com/images/I/71I2VCc-JhL.jpg) ![IMG Stage Line SAM-200D 280W Digital Active Subwoofer Module, 32.0780 - Image 4](https://m.media-amazon.com/images/I/21+-2zEMruL.jpg) ![IMG Stage Line SAM-200D 280W Digital Active Subwoofer Module, 32.0780 - Image 5](https://m.media-amazon.com/images/I/81nI9wk6VHL.jpg) ## Available Options This product comes in different **Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good bit of kit. *by J***G on 7 January 2020* Replaced a burnt out Kef subwoofer amp, had to make a plate up to mount it as this amp is smaller.

After some research this amplifier seemed to fit the bill and I couldn't be happier, It was not too difficult to install I had to make a plate with some MDF I already had, Screw it in and wire it up, Most people with basic DIY skills would manage this without problems. I can honestly say It has made a vast improvement I have more power than the original amp but it has maintained its musicality, Although its main use is for Movies I also play a lot of music and the amplifier performs well, Overall its saved me in the region of £400 for a new Sub and I'm a Happy customer.
