Bag End Infrasub-12 ($1,690) Bag End claims the Infrasub-12 can do 8 Hz - but how does it perform before it drops below the range of human hearing?

What's in the Box?

• Cabinet design sealed, magnetically shielded • Electronics proprietary ELF (Extended Low Frequency) processor • Finish black textured paint • Driver size 12 inches • Rated Power 400 watts continuous • Controls fixed 95-Hz low-pass filter, fixed 95-Hz high-pass filter (line only), phase switch, level, on/off • Warranty 1 year

How Big Is It? • Dimensions (WxHxD) 18 x 15 1/2 x 15 1/4 inches • Volume 1 1/2 cubic feet • Footprint 2 square feet • Weight 56 pounds

Ins & Outs • 3 line-level inputs and outputs • 2 speaker-level inputs

How Low Does It Go? • Bass limit 16 Hz at 65 dB SPL While the Bag End showed it could plumb the depths, it produced only modest SPLs.

How Big the Bang? • Average SPL from 25 to 62 Hz 96.1 dB • Maximum SPL 110 dB at 62 Hz • Dollars per dB $17.58 The sub produced impressive levels at 62 Hz but was 3 to 5 dB below average from 50 Hz on down.

The Bottom Line While the Infrasub-12 can go all the way to 16 Hz, its limited feature set and high cost put it on par with similarly equipped but considerably less expensive competitors.
