We are often asked about amplifiers that are suitable for use with Acoupower Drivers. Acoupower Drivers handle enormous amounts of power and they are 8 Ohms. Delivering 1-5kW of Power into 8 Ohms requires high voltage swings that are out of the realm of most audio amplifiers. However, there are many high quality amplifiers capable of delivering this voltage and power.
High power Professional Audio amplifiers can usually be bridged, and many of them, from companies such as QSC, Crown, Powersoft, Crest, and many other firms are good performance choices and are available at surprisingly low prices (under $1,000). These amplifiers generally have excellent performance and are much more robust that amplifiers typically seen in a home or studio environment. The ONLY drawback to many of these amplifiers in practice is that most often use a fan to cool themselves. Sometimes this is a non issue because the fan noise is very quite and/or the amplifier is in a separate room or closet. Most amplifiers have variable speed fans that do not make a lot of noise until the amplifier is really putting out enormous power. In cases where no fan noise can be tolerated, Crown's K1 and K2 amplifiers are a good option, as they are powerful, and do not use a fan.
Powersoft from Italy has a few amplifier modules that are a great fit for use with Acoupower drivers: These high performance modules start at just $395 in quantities of 1 and also feature low cost digital filtering and signal processing options. Here are the stats on a few of them: DigiMod 1000 = 1,000W into 8 Ohms (Bridged) DigiPower 3600 = 2000W into 8 Ohms (Bridged) Many higher power OEM amplifiers are also available at http://www.digiamps.com |
