Servo Sub Amps

My plate amp just died on me, so I am looking at replacing it . It is verry old so thought it would be best to replace the old 200wrms to something alot beefier. I do not mind upgrading but do not want to do constantly. That is why I would like something with plenty of power. On the question of the servo sub amp issue, Just what is a servo sub amp and does it have to be combined w/servo sub? To my recollection, I was thinking they work in harmony as a push/pull operation with the cone driver to make return of cone faster. Also less distortion and more accurate. Any thoughts?recommendations?

Re: Servo Sub Amps

Have a read on the types of servos and how they work.

What kind of sub do you have? sealed, ported...? What driver are you using? Yes, you have to use a servo driver with a servo amp or you are just wasting money without the benefits. I am using an Oaudio 500w plate amp on my sealed SDX15 and I am very happy with it. Good power and flexibility. There are more opowerful plate amps out there but the cost goes up dramatically. The Oaudio was a good bang for the buck option. Let us know what you are working with and what your budget is.

Re: Servo Sub Amps

Infinity 12" svc 4ohm driver in a ported enclosure. The only reason I want to go with a plate amp is to simplify the replacement with the old one... fill the hole ... withought having to rebuild the enclosure. I have hooked up my QSC RMX 2450 to it and this little 12" rocked for what it is I kid you not!!!! The bass was harder of course, but what really impressed me was the quickness and accuracy of the thing like sound quality. This is why I want something a bit beefier than the old 200w amp. to get the full potential of this sub when I want it. The driver is rated @750wrms, but I carefully gradually put the power to it wirh the QSC and with music and concert bluray and no problem. With movies I have to be a little careful to not exceed Xmax. P.S. the amp was bridged into 4 ohm mono.

Re: Servo Sub Amps

I would suggest the O Audio 500w plate amp.

Re: Servo Sub Amps

Have you looked at any of the Hypex plate amps? Very good build quality and sound. The stereo/bi-amp plates are software configurable in Windows. http://www.hypex.nl/index.php?option...d=77&Itemid=90

Re: Servo Sub Amps

Leave your old plate amp in the box and keep using your QSC.
