    Go straight to the horse's mouth.

    From link:
    "So what kind of amp will power one or more CS subs? Nearly anything. Old stereo amps, old surround receivers, mono-block amps, you name it. SVS’s are tremendously efficient since they require no power robbing equalization to run low. 100 watts delivered to the sub is enough to fill your HT with amazing bass. One of the reasons we offer the CS line is so that some of those venerable Adcoms, Soundcraftsmen, Pioneer, Marantz and other nice amps and receivers get a second lease on life!"

    Jeremy,

    That info is for the CS line, not he CS+ line, though I agree that the poster should contact SVS directly for their suggestion.

    I would think you could get by with 100 W into 4 ohms, but the + line is very good for power handling. 350 to 500 W into 4 ohms would probably produce a better result.

    Just my uninformed opinion,

    im using a 200w (4ohm) amp for my 20-39cs+ until i can get something more powerful and its still pretty sweet. i get uncorrected peaks of 108db (i dont quite know what the frequency that its measuring though, so it could be anywhere from 108db-115db) during AOTC. i wish i could tell you my room size, buts its very oddly shaped so i dont really know.

    The PC+, which uses the same TC Sounds dB12 "Plus" driver as the CS+, is equipped with a 525 watt Indigo BASH amp. That's the continuous power rating into a 4 ohm load, calculated using the RMS voltage value.

    Similarly, SVS offers the Samson S1000 amp for the CS+ and Ultra passive subwoofers, and the Samson is rated at 500 watts continuous power per channel into 4 ohms (RMS voltage).

    To drive the CS+ to its full potential, a 500 watt amp (continuous power into 4 ohms, RMS voltage) is a good bet. Remember, a 3 dB increase in SPL requires a doubling of input power.

    Regards,

    Ed
