IMG Stage Line SAM-200D 280W Digital Active Subwoofer Module, 32.0780

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.

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.

I took a chance on this purchase as there doesn't appear to be many companies that do sub-woofer repairs and my old Tannoy had developed a fault with its amplifier. 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. Quick delivery, Good price thanks,

Wow... I'd been looking for a replacement amp module for my bargain mordaunt short Active subwoofer that had the usual cooked amplifier, which was beyond redemption.. This although a smaller footprint that the Mordaunt i fitted this into the original rear panel, modified with a jigsaw.. The sound and adjustability are beyond what i expected for the price tag, easily adjusted for different levels of bass on music streaming.. Well worth the investment and a great alternative to finding an original mordaunt short unit..

I had an old Kef subwoofer that like everyone else’s broke way too soon! This replacement amp is perfect to get it working again! It doesn’t fit straight off, I got a piece of wood to adapt it to fit as explained in other reviews. Great sound!!

Nothing to dislike for the price. Fills medium sized hall...a bit muddled at high volumes but then you dont need to turn it up to 1/2 even to hear the bass.

The revue by S. Mitchell said it all! (That's why I bought one) I had an KEF Subwoofer that needed up-grading!...Only difference being is that I didn't use the old circuit plate but instead adapted the speaker box to accommodate the new one and bored some ventilation holes at the top to prevent it from overheating! (See photo)...The sound is terrific when hooked up to my av receiver!...set at a level that's not too overpowering when music is being played, (It's not all about the Bass) but cranked-up for my Blu-Ray Collection of 7.1 surround Sci-Fi movies which always need a little bit more volume for the explosive effects! (It's definitely about the Bass)

Made a subwoofer box to house this Amplifier for my surround sound .. I can only say WOOOOOWWWW !!! Infact I do not use it too much as it annoys the neighbours and gives me a headache especially the low frequency rumbles you get in films and adverts.....

Ho trasformato il mio subwoofer push-pull in carico simmetrico passivo di alta qualità in un subwoofer attivo con soli €150 e considerata l'efficenza e l'alta qualità che già avevo nel mio sistema passivo, con questo amplificatore, il risultato è andato oltre le mie aspettative! Io piloto due woofer della Coral da 20cm 100W rms e 8ohm l'uno, messi in parallelo, per cui mi ritrovo a pilotare 200W rms in 4ohm, esattamente uguale alle specifiche del SAM-200D. Lo consiglio, ma ovviamente, l'amplificatore della Monacor, deve essere abbinato a dei componenti di alta qualità ed un mobile fatto a regola d'arte, con calcoli e materiali specifici.

Voor een gesloten subwoofer!

Bei meinem MIVOC 1500 A-II war plötzlich das Subwoofermodul defekt. Da eine Reparatur noch etwas dauern kann, musste also Ersatz her. Das Monacor SAM-200D schien ideal, da von den Abmessungen her passend (Modul ist versenkt eingebaut) und bzgl. Leistung das MIVOC AM 120 MK II sogar noch übertrifft. Also eine Reduzierblende gebastelt, Kabel konfektioniert, eingebaut, angeschlossen und ...wow! Leistung satt. Das Modul treibt das 38cm Chassis auch bei größeren Pegeln brachial an. Sauberer Klang, sehr dynamisch, pegelfest, keine Verzerrungen. Im Vergleich zum AM 120 kommt mir das SAM 200D noch ein Tick dynamischer vor. Selbst enorme Pegelsprünge quasi von Null auf Hundert meistert das SAM 200D sehr gut. Auch die Nebendiszplinen meistert das SAM 200D tadellos. Es gibt kein "Einschaltplopp", keinerlei Rauschen und die Einschaltautomatik schaltet sehr gut. Das SAM 200D ist per Y Kabel an meinem Onkyo TX NR 929 angeschlossen, Pegel leicht erhöht (am Modul dann entsprechend reduziert) und das Modul schaltet nach meinem Empfinden genau richtig ein und schaltet auch nicht zu früh in den Standby. Das hatte das Mivoc AM 120 MK II deutlich schlechter gemacht. Es ist schon beachtlich, was so ein "kleines" Modul im Vergleich zum originalen leistet. Allerdings gibt es ein paar Punkte, die mich einmalig beim Einbau gestört haben. Die Frontplatte ist wirklich sehr knapp mit ihrer Auflagefläche bemessen. das hätte man ruhig jeweils 1cm zugeben können. Auch das Platinenlayout ist arg gedrängt. Einige Bauteile ragen über die Platine leicht hinaus, was man beim Einbau ggf. beachten muss. Dann werden so 3 Sorten Kleber verwendet, um Kabel und Bauteile zu fixieren, wobei sich der Heißkleber teils schon wieder gelöst hatte. Auch hier: hätte man die Platine nicht jeweils 1cm größer machen können, sodas z.B. Elkos nicht vollen Kontakt zu benachbarten Transistoren haben (die hoffentlich nicht zu warm werden)? Der Anschluß des Subwoofers ist meiner Meinung auch nicht ideal gelöst. Das Kabel ist mit Flachsteckern auf der Platine befestigt, was irgendwie keinen Sinn macht, wenn es dann mit Kleber verkleistert durch einen Ferritring geht. Am anderen Ende dann die üblichen Standard Flachstecker. Da bei mir das Kabel zu kurz war und das Modul in eine Wanne eingelassen ist, habe ich 2 6,3mm Flachstecker mit Gehäuse dran gemacht und dort dann den Subwoofer angeschlossen. Das hätte man gleich so lösen können. Aber ok, störte nur einmal beim Einbau. Leistung und Klang zählen und da gibt es nichts zu meckern, der Preis ist absolut ok.

Cette platine marche très bien. La classe D est particulièrement adaptée aux caissons de grave (meilleure efficacité, forte puissance, peu de chauffe, faible encombrement). J'ai remplacé la platine HS d'un Magnat Omega 300 et ça envoie du bois et pas qu'un peu ! J'enlève une étoile car il y a quand quelque chose qui ne va pas : ça fait très "cheap". La plaque fait 3 mm d'épaisseur et est en aluminium et se déforme lorsque l'on serre les vis de fixation, c'est vraiment très limite. Ensuite, le PCB et l'organisation des composants, c'est un peu n'importe quoi et la colle qui fixe le tout à été posée n'importe comment. Ça fait un peu sale quoi... Mais en dehors de ça, mission accomplie!

L'ho sto utilizzando in cassa bass reflex, con un subwoofer acrilic 1200 da 30 cm, spinge abbastanza bene sicuramente non è al top con 200 w rms in 4 ohm, sembra manchi qualcosa, abbastanza soddisfatto.
