We are proud to announce the arrival of our new and improved models of amplifiers. We have brought in four new models. The RD- 5750.1D that does well over 5,000 watts RMS @ 14.4 volts. It will do 5750 @ .75 ohms daily, The RD-3250.1D that offers >3,300 watts RMS @ 14.4, The RD-1750.1D that puts out over 1,750 watts RMS, and the RD-1000.1D that does a cool 1,100 watts RMS. The new amps are a complete upgrade.
The 5750/3250/1750 models are now able to be strapped together with another like amplifier to double the output. With the power, durability, and sound quality unsurpassed we are sure these amplifiers will meet the R.D. Audio customers’ needs.
Our amplifiers were built to perform. We put real world true RMS watt ratings on all of our Amplifiers. They are solid warm sounding amplifiers. We are in process of adding another 4 channel SQ amp and a powerful 2 channel model to complete the 2007 R.D. Audio amplifier lineup.
All Class D models have variable subsonic filters Class D amps are over 90% efficient 18 db crossover slope on all AB and D series amplifiers All models have an variable 18 db bass boost
The RD-5750.1D along with the Heavyweight and Super Heavyweight series of subwoofers are available upon request and payment through you local or Net authorized RD Audio dealers. These are non stocked items for the most part. The subwoofers are built to meet your every need so once they are ordered they are yours and yours alone. More likely than not, there will never be another Subwoofer built the exact same. These products are covered under our full RD Audio warranty covering all products from manufacture defects. This warranty does not cover damage resulting in excess power being given to the products during SPL events. We do offer re cone kits to our competitors at our cost. These custom order products cannot be returned to RD AUDIO for refund for any reason since they are custom ordered.
