The Ampeg SVT-410HLF is a great example of how Ampeg knows that players have different tastes, and make the configuration YOU are looking for. The world-renowned Classic Series Cabinets are synonymous with bass enclosures - they've simply set the standard for decades. The Ampeg SVT-410HLF delivers extended range and unexpected low end from a 4x10-inch cabinet. It features dual Neutrik Speak-On and 1/4-inch input and output jacks. Its high frequency horn is controlled with a variable level attenuator. To prevent overpowering and damaging the horn, a resistive bulb is wired in series with the horn for protection.
