Massive Audio's GTX subs use tight Red stitching that's sewn through a UV treated non-pressed paper cone onto a EROM foam surround. Then it's bonded to a heavy gauge steel basket that's bolted to double stacked high flux Y30 70-150oz Strontium ferrite magnets with a 10mm top plate. Then everything dances on a springy poly cotton spider with high powered woven tinsel leads that connect to spring loaded 5-way binding nickel plated speaker connectors. These woofers scream sound quality and truly represent Massive Audio's commitment to value and performance.

Dont let its diminutive size fool you, this ultra compact Massive Audio E3F EDGE Series Amplifier is a Class D powerhouse capable of up to 1500 Watts RMS at 1 Ohm. With a frequency range of 25Hz - 18KHz this amplifier will deliver high current for Subwoofers, Mid-Range and Full Range Speakers!

Its Class D design enables its compact footprint and cool running within all system configurations. Theres no need to worry about running out of gas, our E3F has a regulated power supply and dual output voltage.

As with all Massive Edge series Amplifiers only the highest quality materials are used. One example is our use of Double Sided, Mil Spec PCBs with Surface Mount Devices. Another Massive Edge family trait is the inclusion of our built-in OEM Line Level Converter with RCA inputs, capable of processing RCA or Speaker levels signals up to 10 Volts! This built in converter eliminates the need for an additional component, thereby reducing cost.

Differential input switching allows for twisted or single end RCA connections to prevent ground noise for those difficult installations and when using a high input source this Amplifier has a built-in auto sensing turn on function. The E3F features variable LPF, HPF and Full Range crossovers for precise tuning.

The E3F also features a 0 12db variable Bass Boost circuit that can be controlled remotely with purchase of our UR1 Bass Boost control and maintaining our legacy of continually upgrading, we include our Next Gen Advanced 5 Way Protection circuitry.
