Bag End puts more power behind its Infrasubs

We remember back in the day when Bag End introduced its ELF (Extra Low Frequency) subs to the home audio market. The promise of really low bass -- +/-3-dB response from 8Hz to 95Hz -- from enclosures less than 2-feet on a side seemed impossible. You read that right -- eight Hertz. Fast forward to present, and the Hobbit-esque ELF that fit in with the "Bag End" name has now been recast as Infrasub. The company's Infra dual integrator system (basically active equalization) that allows the Infrasubs to apparently disregard the cabinet's resonant frequency does require lots of power, though. This is an ideal setting to bring in class-D amplification, and now Bag End has done just that by integrating its P-500 amp into the Infrasub-12 and Infrasub-18 models, delivering 500-Watts (100-Watts more than the previous amp) in a lighter, cooler, more efficient package than before. If you visit the Newseum and like the bass delivery, put these subs on your audition list.
